Various small fixes.
* rs/misc-cppcheck-fixes:
server-info: avoid calling fclose(3) twice in update_info_file()
files_for_each_reflog_ent_reverse(): close stream and free strbuf on error
am: close stream on error, but not stdin
"git fetch-pack" was not prepared to accept ERR packet that the
upload-pack can send with a human-readable error message. It
showed the packet contents with ERR prefix, so there was no data
loss, but it was redundant to say "ERR" in an error message.
* jt/fetch-pack-error-reporting:
fetch-pack: show clearer error message upon ERR
Add finishing touches to a recent topic.
* jk/quarantine-received-objects:
refs: reject ref updates while GIT_QUARANTINE_PATH is set
receive-pack: document user-visible quarantine effects
receive-pack: drop tmp_objdir_env from run_update_hook
"git submodule" script does not work well with strange pathnames.
Protect it from a path with slashes in them, at least.
* bw/submodule-with-bs-path:
submodule: prevent backslash expantion in submodule names
The index file has a trailing SHA-1 checksum to detect file
corruption, and historically we checked it every time the index
file is used. Omit the validation during normal use, and instead
verify only in "git fsck".
* jh/verify-index-checksum-only-in-fsck:
read-cache: force_verify_index_checksum
In a 2- and 3-way merge of trees, more than one source trees often
end up sharing an identical subtree; optimize by not reading the
same tree multiple times in such a case.
* jh/unpack-trees-micro-optim:
unpack-trees: avoid duplicate ODB lookups during checkout
The string-list API used a custom reallocation strategy that was
very inefficient, instead of using the usual ALLOC_GROW() macro,
which has been fixed.
* jh/string-list-micro-optim:
string-list: use ALLOC_GROW macro when reallocing string_list
$GIT_DIR may in some cases be normalized with all symlinks resolved
while "gitdir" path expansion in the pattern does not receive the
same treatment, leading to incorrect mismatch. This has been fixed.
* nd/conditional-config-include:
config: resolve symlinks in conditional include's patterns
path.c: and an option to call real_path() in expand_user_path()
Allow the http.postbuffer configuration variable to be set to a
size that can be expressed in size_t, which can be larger than
ulong on some platforms.
* dt/http-postbuffer-can-be-large:
http.postbuffer: allow full range of ssize_t values
"http.proxy" set to an empty string is used to disable the usage of
proxy. We broke this early last year.
* sr/http-proxy-configuration-fix:
http: fix the silent ignoring of proxy misconfiguraion
http: honor empty http.proxy option to bypass proxy
Change the test descriptions from being treated as binary blobs by
perl to being treated as UTF-8. This ensures that e.g. a test
description like "æ" is counted as 1 character, not 2.
I have WIP performance tests for non-ASCII grep patterns on another

When we complete branch names for "git checkout", we also
complete remote branch names that could trigger the DWIM
behavior. Depending on your workflow and project, this can
be either convenient or annoying.
For instance, my clone of gitster.git contains 74 local
"jk/*" branches, but origin contains another 147. When I
want to checkout a local branch but can't quite remember the
name, tab completion shows me 251 entries. And worse, for a
topic that has been picked up for pu, the upstream branch
name is likely to be similar to mine, leading to a high
probability that I pick the wrong one and accidentally
create a new branch.
This patch adds a way for the user to tell the completion
code not to include DWIM suggestions for checkout. This can
already be done by typing:
git checkout --no-guess jk/<TAB>
but that's rather cumbersome. The downside, of course, is
that you no longer get completion support when you _do_ want
to invoke the DWIM behavior. But depending on your workflow,
that may not be a big loss (for instance, in git.git I am
much more likely to want to detach, so I'd type "git
checkout origin/jk/<TAB>" anyway).

Change the completion of "push --delete <remote> <ref>" to complete
refs on that <remote>, not all refs.
Before this cloning git.git and doing "git push --delete origin
p<TAB>" will complete nothing, since a fresh clone of git.git will
have no "pu" branch, whereas origin/p<TAB> will uselessly complete
origin/pu, but fully qualified references aren't accepted by
"--delete".
Now p<TAB> will complete as "pu". The completion of giving --delete
later, e.g. "git push origin --delete p<TAB>" remains unchanged, this
is a bug, but is a general existing limitation of the bash completion,
and not how git-push is documented, so I'm not fixing that case, but
adding a failing TODO test for it.

git-archimport has an option to register archives at
mirrors.sourcecontrol.net. The sourcecontrol.net domain
still exists, but that hostname no longer exists.
That means this feature is presumably broken. I'll leave the
examination and modification of that to people who might
actually use archimport. But in the meantime, let's wrap the
reference in the documentation in backticks, which will
avoid turning it into a broken link (and thus polluting
linkchecker results).

When we see an error from split_cmdline(), we exit the
function without freeing the copy of the command string we
made.
This was sort-of introduced by 22e5ae5c8 (connect.c: handle
errors from split_cmdline, 2017-04-10). The leak existed
before that, but before that commit fixed the bug, we could
never trigger this else clause in the first place.

The only caller of this function passes in a static buffer
returned from git_path(). This looks dangerous at first
glance, but turns out to be OK because the first thing we do
is xstrdup() the result.
Let's turn this into a git_pathdup(). That's slightly more
efficient (no extra copy), and makes it easier to audit for
dangerous git_path() invocations.
Since there's only a single caller, let's just set this
default path inside the init function. That makes the memory
ownership clear.

Writing directly into the strbuf avoids a useless copy of
the data, and dropping calls to git_path() makes it easier
to audit for dangerous calls.
Note that git_path() does an implicit strbuf_reset(), but in
each of these cases we were either already doing that reset,
or writing into a fresh strbuf anyway.

When performing an interactive rebase in split-index mode,
the commit message that one should rework when squashing commits
can contain some garbage instead of the usual concatenation of
both of the commit messages.
The code uses git_path() to compute the shared index filename, and
passes it to check_and_freshen_file() as its argument; there is no
guarantee that the rotating pathname buffer passed as argument will
stay valid during the life of this call. Make our own copy before
calling the function and pass the copy as its argument to avoid this
risky pattern.

As explained in the document. This option has an advantage over the
command sequence "git worktree add && git worktree lock": there will be
no gap that somebody can accidentally "prune" the new worktree (or soon,
explicitly "worktree remove" it).
"worktree add" does keep a lock on while it's preparing the worktree.
If --lock is specified, this lock remains after the worktree is created.
