Convert lookup_commit, lookup_commit_or_die,
lookup_commit_reference, and lookup_commit_reference_gently to take
struct object_id arguments.
Introduce a temporary in parse_object buffer in order to convert this
function. This is required since in order to convert parse_object and
parse_object_buffer, lookup_commit_reference_gently and
lookup_commit_or_die would need to be converted. Not introducing a
temporary would therefore require that lookup_commit_or_die take a
struct object_id *, but lookup_commit would take unsigned char *,
leaving a confusing and hard-to-use interface.
parse_object_buffer will lose this temporary in a later patch.

Git's source code assumes that unsigned long is at least as precise as
time_t. Which is incorrect, and causes a lot of problems, in particular
where unsigned long is only 32-bit (notably on Windows, even in 64-bit
versions).
So let's just use a more appropriate data type instead. In preparation
for this, we introduce the new `timestamp_t` data type.
By necessity, this is a very, very large patch, as it has to replace all
timestamps' data type in one go.
As we will use a data type that is not necessarily identical to `time_t`,
we need to be very careful to use `time_t` whenever we interact with the
system functions, and `timestamp_t` everywhere else.

The helper function tries to offer a way to conveniently show the

something like

while iterating over a list that has these three elements.
However, there is only one caller, and it passes the same format
string "%s\n" for both the last one and the other ones. Retire the
helper function and update the caller with a simplified version.

Instead of a custom commit walker like get_shallow_commits(), this new
function uses rev-list to mark NOT_SHALLOW to all reachable commits,
except borders. The definition of reachable is to be defined by the
protocol later. This makes it more flexible to define shallow boundary.
The way we find border is paint all reachable commits NOT_SHALLOW. Any
of them that "touches" commits without NOT_SHALLOW flag are considered
shallow (e.g. zero parents via grafting mechanism). Shallow commits and
their true parents are all marked SHALLOW. Then NOT_SHALLOW is removed
from shallow commits at the end.
There is an interesting observation. With a generic walker, we can
produce all kinds of shallow cutting. In the following graph, every
commit but "x" is reachable. "b" is a parent of "a".
x -- a -- o
/ /
x -- c -- b -- o
After this function is run, "a" and "c" are both considered shallow
commits. After grafting occurs at the client side, what we see is
a -- o
/
c -- b -- o
Notice that because of grafting, "a" has zero parents, so "b" is no
longer a parent of "a".
This is unfortunate and may be solved in two ways. The first is change
the way shallow grafting works and keep "a -- b" connection if "b"
exists and always ends at shallow commits (iow, no loose ends). This is
hard to detect, or at least not cheap to do.
The second way is mark one "x" as shallow commit instead of "a" and
produce this graph at client side:
x -- a -- o
/ /
c -- b -- o
More commits, but simpler grafting rules.

This output format prevents format-patch output from breaking
readers if somebody copy+pasted an mbox into a commit message.
Unlike the traditional "mboxo" format, "mboxrd" is designed to
be fully-reversible. "mboxrd" also gracefully degrades to
showing extra ">" in existing "mboxo" readers.
This degradation is preferable to breaking message splitting
completely, a problem I've seen in "mboxcl" due to having
multiple, non-existent, or inaccurate Content-Length headers.
"mboxcl2" is a non-starter since it's inherits the problems
of "mboxcl" while being completely incompatible with existing
tooling based around mailsplit.

A commit log message sometimes tries to line things up using tabs,
assuming fixed-width font with the standard 8-place tab settings.
Viewing such a commit however does not work well in "git log", as
we indent the lines by prefixing 4 spaces in front of them.
This should all line up:
Column 1 Column 2
-------- --------
A B
ABCD EFGH
SPACES Instead of Tabs
Even with multi-byte UTF8 characters:
Column 1 Column 2
-------- --------
Ä B
åäö 100
A Møøse once bit my sister..
Tab-expand the lines in "git log --expand-tabs" output before
prefixing 4 spaces.
This is based on the patch by Linus Torvalds, but at this step, we
require an explicit command line option to enable the behaviour.

In preparation for adding date modes that may carry extra
information beyond the mode itself, this patch converts the
date_mode enum into a struct.
Most of the conversion is fairly straightforward; we pass
the struct as a pointer and dereference the type field where
necessary. Locations that declare a date_mode can use a "{}"
constructor. However, the tricky case is where we use the
enum labels as constants, like:
show_date(t, tz, DATE_NORMAL);
Ideally we could say:
show_date(t, tz, &{ DATE_NORMAL });
but of course C does not allow that. Likewise, we cannot
cast the constant to a struct, because we need to pass an
actual address. Our options are basically:
1. Manually add a "struct date_mode d = { DATE_NORMAL }"
definition to each caller, and pass "&d". This makes
the callers uglier, because they sometimes do not even
have their own scope (e.g., they are inside a switch
statement).
2. Provide a pre-made global "date_normal" struct that can
be passed by address. We'd also need "date_rfc2822",
"date_iso8601", and so forth. But at least the ugliness
is defined in one place.
3. Provide a wrapper that generates the correct struct on
the fly. The big downside is that we end up pointing to
a single global, which makes our wrapper non-reentrant.
But show_date is already not reentrant, so it does not
matter.
This patch implements 3, along with a minor macro to keep
the size of the callers sane.

When we call parse_commit, it will complain to stderr if the
object does not exist or cannot be read. This means that we
may produce useless error messages if this situation is
expected (e.g., because the object is marked UNINTERESTING,
or because revs->ignore_missing_links is set).
We can fix this by adding a new "parse_X_gently" form that
takes a flag to suppress the messages. The existing
"parse_X" form is already gentle in the sense that it
returns an error rather than dying, and we could in theory
just add a "quiet" flag to it (with existing callers passing
"0"). But doing it this way means we do not have to disturb
existing callers.
Note also that the new flag is "quiet_on_missing", and not
just "quiet". We could add a flag to suppress _all_ errors,
but besides being a more invasive change (we would have to
pass the flag down to sub-functions, too), there is a good
reason not to: we would never want to use it. Missing a
linked object is expected in some circumstances, but it is
never expected to have a malformed commit, or to get a tree
when we wanted a commit. We should always complain about
these corruptions.

The callers of get_merge_bases() can choose to leave object flags
used during the merge-base traversal by passing cleanup=0 as a
parameter, but in practice a very few callers can afford to do so
(namely, "git merge-base"), as they need to compute merge base in
preparation for other processing of their own and they need to see
the object without contaminate flags.
Change the function signature of get_merge_bases_many() and
get_merge_bases() to drop the cleanup parameter, so that the
majority of the callers do not have to say ", 1" at the end.
Give a new get_merge_bases_many_dirty() API to support only a few
callers that know they do not need to spend cycles cleaning up the

Usually when we parse a commit, we read it line by line and
handle each individual line (e.g., parse_commit and
parse_commit_header). Sometimes, however, we only care
about extracting a single header. Code in this situation is
stuck doing an ad-hoc parse of the commit buffer.
Let's provide a reusable function to locate a header within
the commit. The code is modeled after pretty.c's
get_header, which is used to extract the encoding.
Since some callers may not have the "struct commit" to go
along with the buffer, we drop that parameter. The only
thing lost is a warning for truncated commits, but that's
OK. This shouldn't happen in practice, and even if it does,
there's no particular reason that this function needs to
complain about it. It either finds the header it was asked
for, or it doesn't (and in the latter case, the caller will
typically complain).

We are already using the flex-array technique; let's
annotate it with our usual FLEX_ARRAY macro. Besides being
more readable, this is slightly more efficient on compilers
that understand flex-arrays.
Note that we need to bump the allocation in add_name_decoration,
which did not explicitly add one byte for the NUL terminator
of the string we are putting into the flex-array (it did not
need to before, because the struct itself was over-allocated
by one byte).

In the previous commit, we made add_name_decoration global
so that adders would not have to access the hash directly.
We now make the hash itself static so that callers _have_ to
add through our function, making sure that all additions go
through a single point. To do this, we have to add one more
accessor function: a way to lookup entries in the hash.
Since the only caller doesn't actually look at the returned
value, but rather only asks whether there is a decoration or
not, we could provide only a boolean "has_name_decoration".
That would allow us to make "struct name_decoration" local
to log-tree, as well.
However, it's unlikely to cause any maintainability harm
making the actual data public, and this interface is more
flexible if we need to look at decorations from other parts
of the code in the future.

The log-tree code keeps a "struct decoration" hash to show
text decorations for each commit during log traversals. It
makes this available to other files by providing global
access to the hash. This can result in other code adding
entries that do not conform to what log-tree expects.
For example, the bisect code adds its own "dist"
decorations to be shown. Originally the bisect code was
correct, but when the name_decoration code grew a new field
in eb3005e (commit.h: add 'type' to struct name_decoration,
2010-06-19), the bisect code was not updated. As a result,
the log-tree code can access uninitialized memory and even
segfault.
We can fix this by making name_decoration's adding function
public. If all callers use it, then any changes to struct
initialization only need to happen in one place (and because
the members come in as parameters, the compiler can notice a
caller who does not supply enough information).
As a bonus, this also means that the decoration hashes
created by the bisect code will use less memory (previously
we over-allocated space for the distance integer, but now we
format it into a temporary buffer and copy it to the final
flex-array).

1. If the format is missing a terminating newline, we add
one automatically. This makes sense for --format=%h, but
not for a truly empty format.
2. We add an extra newline between the pretty-printed
format and a diff or diffstat. If the format is empty,
there's no point in doing so if there's nothing to
separate.
With this patch, one can get a diff with no other cruft out
of "diff-tree --format= $commit".

It could be misleading to keep a signature in a
replacement commit, so let's remove it.
Note that there should probably be a way to sign
the replacement commit created when using --graft,
but this can be dealt with in another commit or
patch series.
