If a pack file is small enough that its entire contents fits within
one mmap window, mmap the file and then immediately close its file
descriptor. This reduces the number of file descriptors that are
needed to read from repositories with many tiny pack files, such
as one that has received 1000 pushes (and created 1000 small pack
files) since its last repack.

Rather than using 'errno == EMFILE' after a failed open() call
to indicate the process is out of file descriptors and an LRU
pack window should be closed, place a hard upper limit on the
number of open packs based on the actual rlimit of the process.
By using a hard upper limit that is below the rlimit of the current
process it is not necessary to check for EMFILE on every single
fd-allocating system call. Instead reserving 25 file descriptors
makes it safe to assume the system call won't fail due to being over
the filedescriptor limit. Here 25 is chosen as a WAG, but considers
3 for stdin/stdout/stderr, and at least a few for other Git code
to operate on temporary files. An additional 20 is reserved as it
is not known what the C library needs to perform other services on
Git's behalf, such as nsswitch or name resolution.
This fixes a case where running `git gc --auto` in a repository
with more than 1024 packs (but an rlimit of 1024 open fds) fails
due to the temporary output file not being able to allocate a
file descriptor. The output file is opened by pack-objects after
object enumeration and delta compression are done, both of which
have already opened all of the packs and fully populated the file
descriptor table.

When "git commit" was rewritten in C (v1.5.4-rc0~78^2~30,

These should generally never happen, as we already

Subject and identity headers may be arbitrarily long. In the
past, we just assumed that single-line headers would be
reasonably short. For multi-line subjects that we squish
into a single line, we just "pre-folded" the data in
pp_title_line by adding a newline and indentation.
There were two problems. One is that, although rare,
single-line messages can actually be longer than the
recommended line-length limits. The second is that the
pre-folding interacted badly with rfc2047 encoding, leading
to malformed headers.
Instead, let's stop pre-folding the subject lines, and just
fold everything based on length in add_rfc2047, whether
it is encoded or not.

The function strbuf_add_wrapped_text takes a NUL-terminated
string. This makes it annoying to wrap strings we have as a
pointer and a length.
Refactoring strbuf_add_wrapped_text and all of its
sub-functions to handle fixed-length strings turned out to
be really ugly. So this implementation is lame; it just
strdups the text and operates on the NUL-terminated version.
This should be fine as the strings we are wrapping are
generally pretty short. If it becomes a problem, we can
optimize later.

Sanity-check config variable names when adding and retrieving them. As a side
effect code duplication between git_config_set_multivar and get_value (in
builtin/config.c) was removed and the common functionality was placed in
git_config_parse_key.
This breaks a test in t1300 which used invalid section-less keys in the tests
for "git -c". However, allowing such names there was useless, since there was
no way to set them via config file, and no part of git actually tried to use
section-less keys. This patch updates the test to use more realistic examples
as well as adding its own test.

The logic in builtin_diffstat assumes that a
complete_rewrite pair should have its lines counted. This is
nonsensical for binary files and leads to confusing things
like:
$ git diff --stat --summary HEAD^ HEAD
foo.rand | Bin 4096 -> 4096 bytes
1 files changed, 0 insertions(+), 0 deletions(-)
$ git diff --stat --summary -B HEAD^ HEAD
foo.rand | 34 +++++++++++++++-------------------
1 files changed, 15 insertions(+), 19 deletions(-)
rewrite foo.rand (100%)
So let's reorder the function to handle binary files first
(which from diffstat's perspective look like complete
rewrites anyway), then rewrites, then actual diffstats.
There are two bonus prizes to this reorder:
1. It gets rid of a now-superfluous goto.
2. The binary case is at the top, which means we can
further optimize it in the next patch.

When creating a new branch using the --track option, we must make sure that
we don't try to set an upstream that does not make sense to follow (using
'git pull') or update (using 'git push'). The current code checks against
using HEAD as upstream (since tracking a symref doesn't make sense). However,
tracking a tag doesn't make sense either. Indeed, tracking _any_ ref that is
not a (local or remote) branch doesn't make sense, and should be disallowed.
This patch achieves this by checking that the ref we're trying to --track
resides within refs/heads/* or refs/remotes/*. This new check replaces the
previous check against HEAD.
A couple of testcases are also added, verifying that we cannot create
branches with tags as upstreams.
Finally, some selftests relying on using a non-branch as an upstream have
been reworked or removed:
- t6040: Reverse the meaning of two tests that depend on the ability to
use (lightweight and annotated) tags as upstreams. These two tests were
originally added in commits 1be570f and 57ffc5f, and this patch reverts the
intention of those two commits.

Users are sometimes confused with two different types of "tracking" behavior
in Git: "remote-tracking" branches (e.g. refs/remotes/*/*) versus the
merge/rebase relationship between a local branch and its @{upstream}
(controlled by branch.foo.remote and branch.foo.merge config settings).
When the push.default is set to 'tracking', it specifies that a branch should
be pushed to its @{upstream} branch. In other words, setting push.default to
'tracking' applies only to the latter of the above two types of "tracking"
behavior.
In order to make this more understandable to the user, we rename the
push.default == 'tracking' option to push.default == 'upstream'.
push.default == 'tracking' is left as a deprecated synonym for 'upstream'.
