We set CURLOPT_PROXYAUTH to use the most secure authentication
method available only when the user has set configuration variables
to specify a proxy. However, libcurl also supports specifying a
proxy through environment variables. In that case libcurl defaults
to only using the Basic proxy authentication method, because we do
not use CURLOPT_PROXYAUTH.
Set CURLOPT_PROXYAUTH to always use the most secure authentication
method available, even when there is no git configuration telling us
to use a proxy. This allows the user to use environment variables to
configure a proxy that requires an authentication method different
from Basic.

The function is called only from one place, which makes sure to have
`interesting_cache` not NULL. Additionally the variable is a
dereferenced a few lines before unconditionally, which would have
resulted in a segmentation fault before hitting this check.

Commit 23af91d (prune: strategies for linked checkouts - 2014-11-30)
adds "--worktrees" to "git prune" without realizing that "git prune" is
for object database only. This patch moves the same functionality to a
new command "git worktree".

When fsck validates a commit or a tag, it scans each line in the
header of the object using helper functions such as "start_with()",
etc. that work on a NUL terminated buffer, but before a1e920a0
(index-pack: terminate object buffers with NUL, 2014-12-08), the
validation functions were fed the object data in a piece of memory
that is not necessarily terminated with a NUL.
We added a helper function require_end_of_header() to be called at
the beginning of these validation functions to insist that the
object data contains an empty line before its end. The theory is
that the validating functions will notice and stop when it hits an
empty line as a normal end of header (or a required header line that
is missing) without scanning past the end of potentially not
NUL-terminated buffer.
But the theory forgot that in the older days, Git itself happily
created objects with only the header lines without a body. This
caused Git 2.2 and later to issue an unnecessary warning in some
existing repositories.
With a1e920a0, we do not need to require an empty line (or the body)
in these objects to safely parse and validate them. Drop the
offending "must have an empty line" check from this helper function,
while keeping the other check to make sure that there is no NUL in
the header part of the object, and adjust the name of the helper to
what it does accordingly.

In the test case, we run setup_git_dir_gently() the first time to read
$GIT_DIR/config so that we can resolve aliases. We'll enter
setup_discovered_git_dir() and may or may not call set_git_dir() near
the end of the function, depending on whether the detected git dir is
".git" or not. This set_git_dir() will set env var $GIT_DIR.
For normal repo, git dir detected via setup_discovered_git_dir() will be
".git", and set_git_dir() is not called. If .git file is used however,
the git dir can't be ".git" and set_git_dir() is called and $GIT_DIR
set. This is the key of this problem.
If we expand an alias (or autocorrect command names), then
setup_git_dir_gently() is run the second time. If $GIT_DIR is not set in
the first run, we run the same setup_discovered_git_dir() as before.
Nothing to see. If it is, however, we'll enter setup_explicit_git_dir()
this time.
This is where the "fun" is. If $GIT_WORK_TREE is not set but
$GIT_DIR is, you are supposed to be at the root level of the
worktree. But if you are in a subdir "foo/bar" (real worktree's top
is "foo"), this rule bites you: your detected worktree is now
"foo/bar", even though the first run correctly detected worktree as
"foo". You get "internal error: work tree has already been set" as a
result.
Bottom line is, when $GIT_DIR is set, $GIT_WORK_TREE should be set too
unless there's no work tree. But setting $GIT_WORK_TREE inside
set_git_dir() may backfire. We don't know at that point if work tree is
already configured by the caller. So set it when work tree is
detected. It does not harm if $GIT_WORK_TREE is set while $GIT_DIR is
not.

The improved ARRAY_SIZE macro uses BARF_UNLESS_AN_ARRAY which expands
to a valid check for recent gcc versions and to 0 for older gcc
versions but is not defined on non-gcc builds.
Non-gcc builds need this macro to expand to 0 as well. The current outer
test (defined(__GNUC__) && (__GNUC__ >= 3)) is a strictly weaker
condition than the inner test (GIT_GNUC_PREREQ(3, 1)) so we can omit the
outer test and cause the BARF_UNLESS_AN_ARRAY macro to be defined
correctly on non-gcc builds as well as gcc builds with older versions.
