Introduce a header file to define a macro that can define the struct
type, initializer, accessor and cleanup functions to manage a commit
slab. Update the "indegree" topological sort facility using it.
To associate 32 flag bits with each commit, you can write:
define_commit_slab(flag32, uint32);
to declare "struct flag32" type, define an instance of it with
struct flag32 flags;
and initialize it by calling
init_flag32(&flags);
After that, a call to flag32_at() function
uint32 *fp = flag32_at(&flags, commit);
will return a pointer pointing at a uint32 for that commit. Once
you are done with these flags, clean them up with
clear_flag32(&flags);
Callers that cannot hard-code how wide the data to be associated
with the commit be at compile time can use the "_with_stride"
variant to initialize the slab.
Suppose you want to give one bit per existing ref, and paint commits
down to find which refs are descendants of each commit. Saying
typedef uint32 bits320[5];
define_commit_slab(flagbits, bits320);
at compile time will still limit your code with hard-coded limit,
because you may find that you have more than 320 refs at runtime.
The code can declare a commit slab "struct flagbits" like this
instead:
define_commit_slab(flagbits, unsigned char);
struct flagbits flags;
and initialize it by:
nrefs = ... count number of refs ...
init_flagbits_with_stride(&flags, (nrefs + 7) / 8);
so that
unsigned char *fp = flagbits_at(&flags, commit);
will return a pointer pointing at an array of 40 "unsigned char"s
associated with the commit, once you figure out nrefs is 320 at
runtime.

Instead of using a single "slab" and keep reallocating it as we find
that we need to deal with commits with larger values of commit->index,
make a "slab" an array of many "slab_piece"s. Each access may need
two levels of indirections, but we only need to reallocate the first
level array of pointers when we have to grow the table this way.

The "indegree" field in the commit object is only used while sorting
a list of commits in topological order, and wasting memory otherwise.
We would prefer to shrink the size of individual commit objects,
which we may have to hold thousands of in-core. We could eject
"indegree" field out from the commit object and represent it as a
dynamic table based on the decoration infrastructure, but the
decoration is meant for sparse annotation and is not a good match.
Instead, let's try a different approach.
- Assign an integer (commit->index) to each commit we keep in-core
(reuse the space of "indegree" field for it);
- When running the topological sort, allocate an array of integers
in bulk (called "slab"), use the commit->index as an index into
this array, and store the "indegree" information there.
This does _not_ reduce the memory footprint of a commit object, but
the commit->index can be used as the index to dynamically associate
commits with other kinds of information as needed.

eb32d236 introduced the OBJ_OFS_DELTA object that uses a relative offset to
identify the base object instead of the 20-byte SHA1 reference. The pack file
documentation only mentions the SHA1 based reference in its description of the
deltified object entry.
Update the pack format documentation to clarify that the deltified object
representation refers to its base using either a relative negative offset or
the absolute SHA1 identifier.

i18n: make the translation of -u advice in one go
|

The advice (consider use of -u when read_directory takes too long) is
separated into 3 different status_printf_ln() calls, and which brings
trouble for translators.
Since status_vprintf() called by status_printf_ln() can handle eol in
buffer, we could simply join these lines into one paragraph.

Using grep "devel\s\+3:" to find at least one whitspace is not
portable on all grep versions; not all grep versions understand "\s"
as a "whitespace".
Use a literal TAB followed by SPACE.
The + as a qualifier for "one or more" is not a basic regular
expression; use egrep instead of grep.

When the source file is empty, the calculation of the merge score
results in a division by zero. In the situation:
== preimage == == postimage ==
F (empty file) F (a large file)
E (a new empty file)
it does not make sense to consider F->E as a rename, so it is better not
to break the pre- and post-image of F.
Bail out early in this case to avoid hitting the divide-by-zero. This
causes the merge score to be left at zero.
