config: fix several access(NULL) calls

When $HOME is unset, home_config_paths fails and returns NULL pointers
for user_config and xdg_config. Valgrind complains with Syscall param
access(pathname) points to unaddressable byte(s).

Don't call blindly access() on these variables, but test them for
NULL-ness before.

git-remote-mediawiki: make mediafiles export optional

It is possible to use git-remote-mediawiki on a tree with both .mw files
and other files. Before git-remote-mediawiki learnt how to export
mediafiles, such mixed trees allowed the user to maintain both the wiki
and other files for the same project in the same repository. With the
newly added support for exporting mediafiles, pushing such mixed trees
would upload unrelated files as mediafiles, which may not be desired.

git-remote-mediawiki: get rid of O(N^2) loop

The algorithm to find a path from the local revision to the remote one
was calling "git rev-list" and parsing its output N times. Run rev-list
only once, and fill a hashtable with the result to optimize the body of
the loop.

git-remote-mediawiki: use --force when adding notes

When notes are created to record a push, it normally doesn't exist yet.
However, when a push is interrupted and then restarted, it may happen
that a commit already has notes attached, and we want to reflect the newly
created remote revision, hence use 'git notes add -f' to override the
existing one

git-remote-mediawiki: properly deal with invalid remote revisions

Some wiki, including https://git.wiki.kernel.org/ have invalid revision

t4012: Actually quote the sed script

The nested quoting is not needed in this cases, thus the previous
version did work just fine. Nevertheless the usage is misleading,
so just achieve nested quoting by using double quotes instead. Lower
the probability of breakage in the future and make the code easier
to read.

NOTE: Just dropping the single quotes around the sed arguments would
      have also been possible.

t4012: use 'printf' instead of 'dd' to generate a binary file

For some reason, 'echo X | dd bs=1k seek=1' creates a file with 2050 bytes
on Windows instead of the expected 1026 bytes, so that a test fails. Since
the actual contents of the file are irrelevant as long as there is at
least one zero byte so that the diff machinery recognizes it as binary,
use printf to generate it.

Merge branch 'jl/maint-1.7.10-recurse-submodules-with-symlink' into jch

When "git submodule add" clones a submodule repository, it can get
confused where to store the resulting submodule repository in the
superproject's .git/ directory when there is a symbolic link in the
path to the current directory.

Will merge to 'next'.
