This change is mostly clerical: the parse_cmd_*() functions need to
use local variables rather than a struct ref_update to collect the
arguments needed for each update, and then call ref_transaction_*() to
queue the change rather than building up the list of changes at the
caller side.

Make (most of) the error messages for invalid input have the same
format [1]:
$COMMAND [SP $REFNAME]: $MESSAGE
Update the tests accordingly.
[1] A few error messages are left with their old form, because
$COMMAND and $REFNAME aren't passed all the way down the call
stack. Maybe those sites should be changed some day, too.

In the original version of this command, for the single case of the
"update" command's <newvalue>, the empty string was interpreted as
being equivalent to 40 "0"s. This shorthand is unnecessary (binary
input will usually be generated programmatically anyway), and it
complicates the parser and the documentation.
So gently deprecate this usage: remove its description from the
documentation and emit a warning if it is found. But for reasons of
backwards compatibility, continue to accept it.

Replace three functions, update_store_new_sha1(),
update_store_old_sha1(), and parse_next_arg(), with a single function,
parse_next_sha1(). The new function takes care of a whole argument,
including checking whether it is there, converting it to an SHA-1, and
emitting errors on EOF or for invalid values. The return value
indicates whether the argument was present or absent, which requires
a bit of intelligence because absent values are represented
differently depending on whether "-z" was used.
The new interface means that the calling functions, parse_cmd_*(),
don't have to interpret the result differently based on the
line_termination mode that is in effect. It also means that
parse_cmd_create() can distinguish unambiguously between an empty new
value and a zeros new value, which fixes a failure in t1400.

Aside from avoiding a tiny bit of work, this makes it transparently
obvious that old_sha1 and new_sha1 are identical. It is arguably a
bit silly to have to set new_sha1 in order to verify old_sha1, but
that is a problem for another day.

Read the whole input into a strbuf at once, and then parse it from
there. This might also be a tad faster, but that is not the point.
The point is to decouple the parsing code from the input source (the
old parsing code had to read new data even in the middle of commands).
Add docstrings for the parsing functions.

The old signature of update_refs() required a
(const struct ref_update **) for its updates_orig argument. The
"const" is presumably there to promise that the function will not
modify the contents of the structures.
But this declaration does not permit the function to be called with a
(struct ref_update **), which is perfectly legitimate. C's type
system is not powerful enough to express what we'd like. So remove
the first "const" from the declaration.
On the other hand, the function *can* promise not to modify the
pointers within the array that is passed to it without inconveniencing
its callers. So add a "const" that has that effect, making the final
declaration
(struct ref_update * const *).

The old parse_arg(), when fed an argument
"refs/heads/a"master
parsed 'refs/heads/a' off of the front of the argument and considered
itself successful. It was only when parse_next_arg() tried to parse
the *next* argument that a problem was noticed. But in fact, the
definition of the input format requires arguments to be terminated by
SP or NUL, so *this* argument is already erroneous and parse_arg()
should diagnose the problem.
So teach parse_arg() to verify that C-quoted arguments are terminated
correctly. If not, emit a more specific error message.
There is no corresponding error case of a non-C-quoted argument that
is not terminated correctly, because the end of a non-quoted argument
is *by definition* a space or NUL, so there is no way to insert other
junk between the "end" of the argument and the argument terminator.
Adjust the tests to expect the new error message. Add a docstring to
the function, incorporating the comments that were formerly within the
function plus some added information.

The pack bitmap format requires that we have a single bit
for each object in the pack, and that each object's bitmap
represents its complete set of reachable objects. Therefore
we have no way to represent the bitmap of an object which
references objects outside the pack.
We notice this problem while generating the bitmaps, as we
try to find the offset of a particular object and realize
that we do not have it. In this case we die, and neither the
bitmap nor the pack is generated. This is correct, but
perhaps a little unfriendly. If you have bitmaps turned on
in the config, many repacks will fail which would otherwise
succeed. E.g., incremental repacks, repacks with "-l" when
you have alternates, ".keep" files.
Instead, this patch notices early that we are omitting some
objects from the pack and turns off bitmaps (with a
warning). Note that this is not strictly correct, as it's
possible that the object being omitted is not reachable from
any other object in the pack. In practice, this is almost
never the case, and there are two advantages to doing it
this way:
1. The code is much simpler, as we do not have to cleanly
abort the bitmap-generation process midway through.
2. We do not waste time partially generating bitmaps only
to find out that some object deep in the history is not
being packed.

When we are sending a pack for push or fetch, we may reuse a
chunk of packfile without even parsing it. The progress
meter then looks like this:
Reusing existing pack: 3440489, done.
Counting objects: 3, done.
The first line shows that we are reusing a large chunk of
objects, and then we further count any objects not included
in the reused portion with an actual traversal.
These are all implementation details that the user does not
need to care about. Instead, we can show the reused objects
in the normal "counting..." progress meter (which will
simply go much faster than normal), and then continue to add
to it as we traverse.

When the "--all-progress" option is in effect, pack-objects
shows a progress report for the "writing" phase. If the
repository has bitmaps and we are reusing a packfile, the
user sees no progress update until the whole packfile is
sent. Since this is typically the bulk of what is being
written, it can look like git hangs during this phase, even
though the transfer is proceeding.
This generally only happens with "git push" from a
repository with bitmaps. We do not use "--all-progress" for
fetch (since the result is going to index-pack on the
client, which takes care of progress reporting). And for
regular repacks to disk, we do not reuse packfiles.
We already have the progress meter setup during
write_reused_pack; we just need to call display_progress
whiel we are writing out the pack. The progress meter is
attached to our output descriptor, so it automatically
handles the throughput measurements.
However, we need to update the object count as we go, since
that is what feeds the percentage we show. We aren't
actually parsing the packfile as we send it, so we have no
idea how many objects we have sent; we only know that at the
end of N bytes, we will have sent M objects. So we cheat a
little and assume each object is M/N bytes (i.e., the mean
of the objects we are sending). While this isn't strictly
true, it actually produces a more pleasing progress meter
for the user, as it moves smoothly and predictably (and
nobody really cares about the object count; they care about
the percentage, and the object count is a proxy for that).
One alternative would be to actually show two progress
meters: one for the reused pack, and one for the rest of the
objects. That would more closely reflect the data we have
(the first would be measured in bytes, and the second
measured in objects). But it would also be more complex and
annoying to the user; rather than seeing one progress meter
counting up to 100%, they would finish one meter, then start
another one at zero.
