Ævar Arnfjörð Bjarmason 3e4ebe3a40 doc txt & -h consistency: use "git foo" form, not "git-foo"
Use the "git cmd" form instead of "git-cmd" for both "git
receive-pack" and "git credential-cache--daemon".

For "git-receive-pack" we do have a binary with that name, even when
installed with SKIP_DASHED_BUILT_INS=YesPlease, but for the purposes
of the SYNOPSIS let's use the "git cmd" form like everywhere else. It
can be invoked like that (and our tests do so), the parts of our
documentation that explain when you need to use the dashed form do so,
and use it.

Ævar Arnfjörð Bjarmason 8c9e292dc0 doc txt & -h consistency: add missing options and labels
Fix various issues of SYNOPSIS and -h output syntax where:

 * Options such as --force were missing entirely
 * ...or the short option, such as -f

 * We said "opts" or "options", but could instead enumerate
   the (small) set of supported options

 * Options that were missing entirely (ls-remote's --sort=<key>)

   As we can specify "--sort" multiple times (it's backed by a
   string-list" it should really be "[(--sort=<key>)...]", which is
   what "git for-each-ref" lists it as, but let's leave that issue for
   a subsequent cleanup, and stop at making these consistent. Other
   "ref-filter.h" users share the same issue, e.g. "git-branch.txt".

 * For "verify-tag" and "verify-commit" we were missing the "--raw"
   option.

Ævar Arnfjörð Bjarmason a0c3244796 doc SYNOPSIS & -h: use "-" to separate words in labels, not "_"
Change "builtin/credential-cache--daemon.c" to use "<socket-path>" not
"<socket_path>" in a placeholder label, almost all of our
documentation uses this form.

This is now consistent with the "If a placeholder has multiple words,
they are separated by dashes" guideline added in
9c9b4f2f8b (standardize usage info string format, 2015-01-13), let's
add a now-passing test to assert that that's the case.

To do this we need to introduce a very sed-powered parser to extract
the SYNOPSIS from the *.txt, and handle not all commands with "-h"
having a corresponding *.txt (e.g. "bisect--helper"). We'll still want
to handle syntax edge cases in the *.txt in subsequent commits for
other checks, but let's do that then.

Jeff Hostetler 55144ccb0a unix-socket: add backlog size option to unix_stream_listen()
Update `unix_stream_listen()` to take an options structure to override
default behaviors.  This commit includes the size of the `listen()` backlog.

Jeff King b5dd96b70a make credential helpers builtins
There's no real reason for credential helpers to be separate binaries. I
did them this way originally under the notion that helper don't _need_
to be part of Git, and so can be built totally separately (and indeed,
the ones in contrib/credential are). But the ones in our main Makefile
build on libgit.a, and the resulting binaries are reasonably large.

We can slim down our total disk footprint by just making them builtins.
This reduces the size of:

  make strip install

from 29MB to 24MB on my Debian system.

Note that credential-cache can't operate without support for Unix
sockets. Currently we just don't build it at all when NO_UNIX_SOCKETS is
set. We could continue that with conditionals in the Makefile and our
list of builtins. But instead, let's build a dummy implementation that
dies with an informative message. That has two advantages:

  - it's simpler, because the conditional bits are all kept inside
    the credential-cache source

  - a user who is expecting it to exist will be told _why_ they can't
    use it, rather than getting the "credential-cache is not a git
    command" error which makes it look like the Git install is broken.

Note that our dummy implementation does still respond to "-h" in order
to appease t0012 (and this may be a little friendlier for users, as
well).
