If the first 18 bytes of the SHA1's of all entries are the same then
sha1_pos() dies and reports that the lower and upper limits of the
binary search were the same that this wasn't supposed to happen. This
is wrong because the remaining two bytes could still differ.
Furthermore: It wouldn't be a problem if they actually were the same,
i.e. if all entries have the same SHA1. The code already handles
duplicates just fine. Simply remove the erroneous check.

Windows does not have POSIX-like signals, and so we ignore all
operations on the non-existent signal mask machinery.
Do not turn sigemptyset into a function, but leave it a macro that
erases the code in the argument because it is used to set sa_mask
of a struct sigaction, but our dummy in mingw.h does not have that

This patch fixes two problems with using :(glob) (or even "*.c"
without ":(glob)").
The first one is we forgot to turn on the 'recursive' flag in struct
pathspec. Without that, tree_entry_interesting() will not mark
potential directories "interesting" so that it can confirm whether
those directories have anything matching the pathspec.
The marking directories interesting has a side effect that we need to
walk inside a directory to realize that there's nothing interested in
there. By that time, 'archive' code has already written the (empty)
directory down. That means lots of empty directories in the result
archive.
This problem is fixed by lazily writing directories down when we know
they are actually needed. There is a theoretical bug in this
implementation: we can't write empty trees/directories that match that
pathspec.
path_exists() is also made stricter in order to detect non-matching
pathspec because when this 'recursive' flag is on, we most likely
match some directories. The easiest way is not consider any
directories "matched".

When a reflog is deleted, e.g. when "git stash" clears its stashes,
"git rev-parse --verify --quiet" dies:
fatal: Log for refs/stash is empty.
The reason is that the get_sha1() code path does not allow us
to suppress this message.
Pass the flags bitfield through get_sha1_with_context() so that
read_ref_at() can suppress the message.
Use get_sha1_with_context1() instead of get_sha1() in rev-parse
so that the --quiet flag is honored.

Blocked and ignored signals -- but not caught signals -- are inherited
across exec. Some callers with sloppy signal-handling behavior can call
git with SIGPIPE blocked or ignored, even non-deterministically. When
SIGPIPE is blocked or ignored, several git commands can run indefinitely,
ignoring EPIPE returns from write() calls, even when the process that
called them has gone away. Our specific case involved a pipe of git
diff-tree output to a script that reads a limited amount of diff data.
In an ideal world, git would never be called with SIGPIPE blocked or
ignored. But in the real world, several real potential callers, including
Perl, Apache, and Unicorn, sometimes spawn subprocesses with SIGPIPE
ignored. It is easier and more productive to harden git against this
mistake than to clean it up in every potential parent process.

When we run `branch --merged`, we use prepare_revision_walk
with the merge-filter marked as UNINTERESTING. Any branch
tips that are marked UNINTERESTING after it returns must be
ancestors of that commit. As we iterate through the list of
refs to show, we check item->commit->object.flags to see
whether it was marked.
This interacts badly with --verbose, which will do a
separate walk to find the ahead/behind information for each
branch. There are two bad things that can happen:
1. The ahead/behind walk may get the wrong results,
because it can see a bogus UNINTERESTING flag leftover
from the merge-filter walk.
2. We may omit some branches if their tips are involved in
the ahead/behind traversal of a branch shown earlier.
The ahead/behind walk carefully cleans up its commit
flags, meaning it may also erase the UNINTERESTING
flag that we expect to check later.
We can solve this by moving the merge-filter state for each
ref into its "struct ref_item" as soon as we finish the
merge-filter walk. That fixes (2). Then we are free to clear
the commit flags we used in the walk, fixing (1).
Note that we actually do away with the matches_merge_filter
helper entirely here, and inline it between the revision
walk and the flag-clearing. This ensures that nobody
accidentally calls it at the wrong time (it is only safe to
check in that instant between the setting and clearing of
the global flag).

When operating with the stateless RPC mode, we will receive a nonce
issued by another instance of us that advertised our capability and
refs some time ago. Update the logic to check received nonce to
detect this case, compute how much time has passed since the nonce
was issued and report the status with a new environment variable
GIT_PUSH_CERT_NONCE_SLOP to the hooks.
GIT_PUSH_CERT_NONCE_STATUS will report "SLOP" in such a case. The
hooks are free to decide how large a slop it is willing to accept.
Strictly speaking, the "nonce" is not really a "nonce" anymore in
the stateless RPC mode, as it will happily take any "nonce" issued
by it (which is protected by HMAC and its secret key) as long as it
is fresh enough. The degree of this security degradation, relative
to the native protocol, is about the same as the "we make sure that
the 'git push' decided to update our refs with new objects based on
the freshest observation of our refs by making sure the values they
claim the original value of the refs they ask us to update exactly
match the current state" security is loosened to accomodate the
stateless RPC mode in the existing code without this series, so
there is no need for those who are already using smart HTTP to push
to their repositories to be alarmed any more than they already are.
In addition, the server operator can set receive.certnonceslop
configuration variable to specify how stale a nonce can be (in
seconds). When this variable is set, and if the nonce received in
the certificate that passes the HMAC check was less than that many
seconds old, hooks are given "OK" in GIT_PUSH_CERT_NONCE_STATUS
(instead of "SLOP") and the received nonce value is given in
GIT_PUSH_CERT_NONCE, which makes it easier for a simple-minded
hook to check if the certificate we received is recent enough.

The "--signed" option received by "git push" is first passed to the
transport layer, which the native transport directly uses to notice
that a push certificate needs to be sent. When the transport-helper
is involved, however, the option needs to be told to the helper with
set_helper_option(), and the helper needs to take necessary action.
For the smart-HTTP helper, the "necessary action" involves spawning
the "git send-pack" subprocess with the "--signed" option.
Once the above all gets wired in, the smart-HTTP transport now can
use the push certificate mechanism to authenticate its pushes.
Add a test that is modeled after tests for the native transport in
t5534-push-signed.sh to t5541-http-push-smart.sh. Update the test
Apache configuration to pass GNUPGHOME environment variable through.
As PassEnv would trigger warnings for an environment variable that
is not set, export it from test-lib.sh set to a harmless value when
GnuPG is not being used in the tests.
Note that the added test is deliberately loose and does not check
the nonce in this step. This is because the stateless RPC mode is
inevitably flaky and a nonce that comes back in the actual push
processing is one issued by a different process; if the two
interactions with the server crossed a second boundary, the nonces
will not match and such a check will fail. A later patch in the
series will work around this shortcoming.
