The ends_with function is essentially a simplified version
of strip_suffix, in which we throw away the stripped length.
Implementing it as an inline on top of strip_suffix has two
advantages:
1. We save a bit of duplicated code.
2. The suffix is typically a string literal, and we call
strlen on it. By making the function inline, many
compilers can replace the strlen call with a constant.

Many callers of ends_with want to not only find out whether
a string has a suffix, but want to also strip it off. Doing
that separately has two minor problems:
1. We often run over the string twice (once to find
the suffix, and then once more to find its length to
subtract the suffix length).
2. We have to specify the suffix length again, which means
either a magic number, or repeating ourselves with
strlen("suffix").
Just as we have skip_prefix to avoid these cases with
starts_with, we can add a strip_suffix to avoid them with
ends_with.
Note that we add two forms of strip_suffix here: one that
takes a string, with the resulting length as an
out-parameter; and one that takes a pointer/length pair, and
reuses the length as an out-parameter. The latter is more
efficient when the caller already has the length (e.g., when
using strbufs), but it can be easy to confuse the two, as
they take the same number and types of parameters.
For that reason, the "mem" form puts its length parameter
next to the buffer (since they are a pair), and the string
form puts it at the end (since it is an out-parameter). The
compiler can notice when you get the order wrong, which
should help prevent writing one when you meant the other.

Instead of using strbuf to create a message string in case a path is
too long for our fixed-size buffer, replace that buffer with a strbuf
and thus get rid of the limitation.

When many branches contain a commit, the branches used to be shown in
the form "A, B and many more", where A, B can be master of current
HEAD. But there are more which might be interesting to always know about.
For example, "origin/master".
The new option, visiblerefs, is stored in ~/.gitk. It contains a list
of references which are always shown before "and many more" if they
contain the commit. By default it is `{"master"}', which is compatible
with previous behavior.

105b5d3f ("gitk: Use mktemp -d to avoid predictable temporary
directories") introduced a dependency on mkdtemp, which is not
available on Windows.
Use the original temporary directory behavior when mkdtemp fails.
This makes the code use mkdtemp when available and gracefully
fallback to the existing behavior when it is not available.

One of the purposes of "git replace --edit" is to help a
user repair objects which are malformed or corrupted.
Usually we pretty-print trees with "ls-tree", which is much
easier to work with than the raw binary data. However, some
forms of corruption break the tree-walker, in which case our
pretty-printing fails, rendering "--edit" useless for the
user.
This patch introduces a "--raw" option, which lets you edit
the binary data in these instances.

When a file descriptor is given to run_command via the
"in", "out", or "err" parameters, run_command takes
ownership. The descriptor will be closed in the parent
process whether the process is spawned successfully or not,
and closing it again is wrong.
In practice this has not caused problems, because we usually
close() right after start_command returns, meaning no other
code has opened a descriptor in the meantime. So we just get
EBADF and ignore it (rather than accidentally closing
somebody else's descriptor!).

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).
