  submodule: don't access the .gitmodules cache entry after removing it

Introduce commit.gpgsign configuration variable to force every
commit to be GPG signed.  The variable cannot be overriden from the
command line of some of the commands that create commits except for
"git commit" and "git commit-tree", but I am not convinced that it
is a good idea to sprinkle support for --no-gpg-sign everywhere,
which in turn means that this configuration variable may not be
such a good idea.

* nv/commit-gpgsign-config:
  test the commit.gpgsign config option
  commit-tree: add and document --no-gpg-sign
  commit-tree: add the commit.gpgsign option to sign all commits

db5360f3 (name-hash: refactor polymorphic index_name_exists();
2013-09-17) split index_name_exists() into index_file_exists() and
index_dir_exists() but retained index_name_exists() as a thin wrapper
to avoid disturbing possible in-flight topics. Since this change
landed in 'master' some time ago and there are no in-flight topics
referencing index_name_exists(), retire it.

The tests are checking that :

- when commit.gpgsign is true, "git commit" creates signed commits

- when commit.gpgsign is false, "git commit" creates unsigned commits

- when commit.gpgsign is true, "git commit --no-gpg-sign" creates
  unsigned commits

- when commit.gpgsign is true, "git rebase -f" creates signed commits

corresponding option for now.

Per Documentation/CodingGuidelines most C files in git start with
a #include of git-compat-util.h or another header file that includes
it, such as cache.h or builtin.h.  This file doesn't need anything
beyond "git-compat-util.h", so use that.

Remove a #include of the system header <stdio.h> since it is already
included by "git-compat-util.h".

Teach add_cacheinfo to tell make_cache_entry to skip refreshing stat
information when a file is missing from the work tree.  We do not want
the index to be stat-dirty after the merge but also do not want to fail
when a file happens to be missing.

This fixes the 'merge-recursive w/ empty work tree - ours has rename'
case in t3030-merge-recursive.

Sometimes when working with a large repository it can be useful to try
out a merge and only check out conflicting files to disk (for example as
a speed optimization on a server).  Until v1.7.7-rc1~28^2~20
(merge-recursive: When we detect we can skip an update, actually skip
it, 2011-08-11), it was possible to do so with the following idiom:

	# Prepare a temporary index and empty work tree.
	GIT_INDEX_FILE="$PWD/tmp-$$-index" &&
	export GIT_INDEX_FILE &&
	GIT_WORK_TREE="$PWD/tmp-$$-work" &&
	export GIT_WORK_TREE &&
	mkdir "$GIT_WORK_TREE" &&

	# Convince the index that our side is on disk.
	git read-tree -i -m $ours &&
	git update-index --ignore-missing --refresh &&

	# Merge their side into our side.
	bases=$(git merge-base --all $ours $theirs) &&
	git merge-recursive $bases -- $ours $theirs &&
	tree=$(git write-tree)

Nowadays, that still works and the exit status is the same, but
merge-recursive produces a diagnostic if "our" side renamed a file:

	error: addinfo_cache failed for path 'dst'

Add a test to document this regression.

"git log --left-right A...B" lost the "leftness" of commits
