Convert several calls of getcwd() and die() to use xgetcwd() instead.
This way we get rid of fixed-size buffers (which can be too small
depending on the used file system) and gain consistent error messages.

Add the helper function xgetcwd(), which returns the current directory
or dies. The returned string has to be free()d after use.

Use strbuf instead of fixed-sized buffers in real_path() in order to
avoid the size limitations of the latter.

Store the original working directory in a strbuf instead of in a

Convert setup_git_directory_gently_1() and its helper functions
setup_explicit_git_dir(), setup_discovered_git_dir() and
setup_bare_git_dir() to use a struct strbuf to hold the current working
directory. Replacing the PATH_MAX-sized buffer used before removes a
path length limition on some file systems. The functions are converted
all in one go because they all read and write the variable cwd.

Instead of using a PATH_MAX-sized buffer, which can be too small on some
file systems, use strbuf_getcwd(), which handles any path getcwd()
returns. Also preserve the errno set by strbuf_getcwd() instead of
setting it to ENAMETOOLONG; that way a more appropriate error message
can be shown based on the actual reason for failing.

Add strbuf_getcwd(), which puts the current working directory into a
strbuf. Because it doesn't use a fixed-size buffer it supports
arbitrarily long paths, provided the platform's getcwd() does as well.
At least on Linux and FreeBSD it handles paths longer than PATH_MAX
just fine.

A handful of code paths had to read the commit object more than
once when showing header fields that are usually not parsed. The
internal data structure to keep track of the contents of the commit
object has been updated to reduce the need for this double-reading,

We create a directory that cannot be removed, confirm that
it cannot be removed, and then fix it like:
chmod 0 foo &&
test_must_fail git clean -d -f &&
chmod 755 foo
If the middle step fails but leaves the directory (e.g., the
bug is that clean does not notice the failure), this
pollutes the test repo with an unremovable directory. Not
only does this cause further tests to fail, but it means
that "rm -rf" fails on the whole trash directory, and the
user has to intervene manually to even re-run the test script.
We can bump the "chmod 755" recovery to a test_when_finished
block to be sure that it always runs.

While checking if a new alternate object database is a duplicate make
sure that old and new base paths have the same length before comparing
them with memcmp. This avoids overrunning the buffer of the existing
entry if the new one is longer and it stops rejecting foobar/ after
foo/ was already added.

The final test in t7510 checks that "--format" placeholders
that look similar to GPG placeholders (but that we don't
actually understand) are passed through. That test was
placed in t7510, since the other GPG placeholder tests are
there. However, it does not have a GPG prerequisite, because
it is not actually checking any signed commits.
This causes the test to erroneously fail when gpg is not
installed on a system, however. Not because we need signed
commits, but because we need _any_ commit to run "git log".
If we don't have gpg installed, t7510 doesn't create any
commits at all.
We can fix this by moving the test into t6006. This is
arguably a better place anyway, because it is where we test
most of the other placeholders (we do not test GPG
placeholders there because of the infrastructure needed to
make signed commits).

"git status" (and "git commit") behaved as if changes in a modified
submodule are not there if submodule.*.ignore configuration is set,
which was misleading. The configuration is only to unclutter diff
output during the course of development, and should not to hide
changes in the "status" output to cause the users forget to commit
them.

"git status", even though it is a read-only operation, tries to

is running. Detect such a race and avoid overwriting the index.
