In HTTP with keep-alive it's not uncommon for the client to notice that
the server decided to stop maintaining the current connection only when
sending a new request. This naturally results in -EPIPE and possibly
SIGPIPE.
The subversion library itself makes no provision for SIGPIPE. Some
combinations of the underlying libraries do (typically SIG_IGN-ing it),
some don't.
Presumably for that reason all subversion commands set SIGPIPE to
SIG_IGN early in their main()-s.
So should we.
This, together with the previous patch, fixes the notorious "git-svn
died of signal 13" problem (see e.g.
http://thread.gmane.org/gmane.comp.version-control.git/134936).

In order to maintain consistency of the database mapping svn revision
numbers to git commit ids, rev_map_set() defers signal processing until
it's finished with an append transaction.[*]
The conventional way to achieve this is through sigprocmask(), which is
available in perl in the standard POSIX module.
This is implemented by this patch. One important consequence of it is
that the signal handlers won't be unconditionally set to SIG_DFL anymore
upon the first invocation of rev_map_set() as they used to. As a
result, the signals ignored by git-svn parent will remain ignored;
otherwise the behavior remains the same.
This patch paves the way to ignoring SIGPIPE throughout git-svn which
will be done in the followup patch.
[*] Deferring signals is not enough to ensure the database consistency:
the program may die on SIGKILL or power loss, run out of disk space,
etc. However that's a separate issue that this patch doesn't address.

Since bc7a96a (mergetool--lib: Refactor tools into separate files,
2011-08-18), it is possible to add a new diff tool by creating a simple
script in the '$(git --exec-path)/mergetools' directory. Updating the
difftool help text is still a manual process, and the documentation can
easily go out of sync.
This commit teaches difftool the '--tool-help' option, which:
- Reads the list of valid tools from 'mergetools/*'
- Determines which of them are actually installed
- Determines which are capable of diffing (i.e. not just a merge tool)
- Prints the resulting list for the user

The bash completion doesn't work when certain options to git itself are
specified, e.g. 'git --no-pager <TAB>' errors out with
error: invalid key: alias.--no-pager
The main _git() completion function finds out the git command name by
looping through all the words on the command line and searching for
the first word that is not a known option for the git command.
Unfortunately the list of known git options was not updated in a long
time, and newer options are not skipped but mistaken for a git command.
Such a misrecognized "command" is then passed to __git_aliased_command(),
which in turn passes it to a 'git config' query, hence the error.
Currently the following options are misrecognized for a git command:
-c --no-pager --exec-path --html-path --man-path --info-path
--no-replace-objects --work-tree= --namespace=
To fix this we could just update the list of options to be skipped,
but the same issue will likely arise, if the git command learns a new
option in the future. Therefore, to make it more future proof against
new options, this patch changes that loop to skip all option-looking
words, i.e. words starting with a dash.
We also have to handle the '-c' option specially, because it takes a
configutation parameter in a separate word, which must be skipped,
too.

"--exec-path" looks to the completion script like an unambiguous
successful completion, but it is wrong to emit a SP after it as if
declaring that we are done with completion; the user could be trying
to do
git --exec-path; # print name of helper directory
or
git --exec-path=/path/to/alternative/helper/dir <subcommand>
so the most helpful thing to do is to leave out the trailing space and
leave it to the operator to type an equal sign or carriage return
according to the situation.

git-gc executes many sub-commands. The argument list for
some of these is constant, but for others we add more
arguments at runtime. The latter is implemented by allocating
a constant extra number of NULLs, and either using a custom
append function, or just referencing unused slots by number.
As of commit 7e52f56, which added two new arguments, it is
possible to exceed the constant number of slots for "repack"
by running "git gc --aggressive", causing "git gc" to die.
This patch converts all of the static argv lists to use
argv-array. In addition to fixing the overflow caused by
7e52f56, it has a few advantages:
1. We can drop the custom append function (which,
incidentally, had an off-by-one error exacerbating the
static limit).
2. We can drop the ugly magic numbers used when adding
arguments to "prune".
3. Adding further arguments will be easier; you can just
add new "push" calls without worrying about increasing
any static limits.

An empty argv-array is initialized to point to a static
empty NULL-terminated array. The original implementation
separates the actual storage of the NULL-terminator from the
pointer to the list. This makes the exposed type a "const
char **", which nicely matches the type stored by the
argv-array.
However, this indirection means that one cannot use
empty_argv to initialize a static variable, since it is
not a constant.
Instead, we can expose empty_argv directly, as an array of
pointers. The only place we use it is in the ARGV_ARRAY_INIT
initializer, and it decays to a pointer appropriately there.
