builtin/apply: introduce 'struct apply_state' to start libifying
Currently commands that want to use the apply functionality have to launch
a "git apply" process which can be bad for performance.
Let's start libifying the apply functionality and to do that we first need
to get rid of the global variables in "builtin/apply.c".
This patch introduces "struct apply_state" into which all the previously
global variables will be moved. A new parameter called "state" that is a
pointer to the "apply_state" structure will come at the beginning of the
helper functions that need it and will be passed around the call chain.
To start let's move the "prefix" and "prefix_length" global variables into
"struct apply_state".

As the value returned by gitdiff_verify_name() is put into the

it is simpler to pass the address of the variable and have

"git describe --contains" often made a hard-to-justify choice of
tag to give name to a given commit, because it tried to come up
with a name with smallest number of hops from a tag, causing an old
commit whose close descendant that is recently tagged were not
described with respect to an old tag but with a newer tag. It did
not help that its computation of "hop" count was further tweaked to
penalize being on a side branch of a merge. The logic has been
updated to favor using the tag with the oldest tagger date, which
is a lot easier to explain to the end users: "We describe a commit
in terms of the (chronologically) oldest tag that contains the
commit."

Some multi-byte character encodings (such as Shift_JIS and GBK) have
characters whose final bytes is an ASCII '\' (0x5c), and they
will be displayed as funny-characters even if $fallback_encoding is
correct. This is because `highlight` command always expects UTF-8
encoded strings from STDIN.
On Cygwin, object creation uses the "create a temporary and then
rename it to the final name" pattern, not "create a temporary,

This is necessary to use Git on Windows shared directories, and is
already enabled for the MinGW and plain Windows builds. It also
has been used in Cygwin packaged versions of Git for quite a while.

The last test added to 't5510-fetch' in 0898c9628104 (fetch: release
pack files before garbage-collecting, 2016-01-13) may sporadically
trigger following error message from the test harness:
rm: cannot remove 'trash directory.t5510-fetch/auto-gc/.git': Directory not empty
The test in question forces an auto-gc, which, if the system supports
it, runs in the background by default, and occasionally takes long
enough for the test to finish and for 'test_done' to start
housekeeping. This can lead to the test's 'git gc --auto' in the
background and 'test_done's 'rm -rf $trash' in the foreground racing
each other to create and delete files and directories. It might just
happen that 'git gc' re-creates a directory that 'rm -rf' already
visited and removed, which ultimately triggers the above error.
Disable detaching the auto-gc process to ensure that it finishes
before the test can continue, thus avoiding this racy situation.

We introduce a way to send custom HTTP headers with all requests.
This allows us, for example, to send an extra token from build agents
for temporary access to private repositories. (This is the use case that
triggered this patch.)
Note that `curl_easy_setopt(..., CURLOPT_HTTPHEADER, ...)` takes only
a single list, overriding any previous call. This means we have to
collect _all_ of the headers we want to use into a single list, and
feed it to cURL in one shot. Since we already unconditionally set a
"pragma" header when initializing the curl handles, we can add our new
headers to that list.
For callers which override the default header list (like probe_rpc),
we provide `http_copy_default_headers()` so they can do the same
trick.
Big thanks to Jeff King and Junio Hamano for their outstanding help and
patient reviews.
