Convert valid %xx expressions in querystring to ascii, ignore invalid
expressions (i.e. eat the three characters %xx).

This adds the ability to show a search box in any pageheader with correct href and
hidden form data, but does not enable the box on any pages.

With a working diff, it really has all the basics.
Next steps will be to make it more usable and less ugly :)

It gives us no extra info whatsoever to show "----------" for either new
or old mode, it's just noise (especially since we now show the "old"
filemode for deleted files)

Compare current commit with 1.parent, and for each affected file display
current filemode, old filemode if changed, current filename and source
filename if it was a copy/rename.

Replace the call to lookup_commit() with a call to lookup_commit_reference,
since it handles reading and parsing of the commit object internally.

We want all four of these when showing a commit, so save them in the
commitinfo struct.
Btw: There's probably no good reason to save committer timestamp since
it's already available in commit->date. But it doesn't hurt us either,
and it makes the parser look more complete, so we just do it.

Make sure we chdir(2) back to the original getcwd(2) when a page
has been generated. Also, if the cgit_cache_root do not exist,
try to create it.
This is a feature intended to ease testing/debugging.

This adds support for the following options to cgit:
--root=<path>
--cache=<path>
--nocache
--query=<querystring>
--repo=<reponame>
--page=<pagename>
--head=<branchname>
--sha1=<sha1>
--ofs=<number>
On startup, /etc/cgitrc is parsed, followed by argument parsing and
finally querystring parsing.
If --nocache is specified (or set in /etc/gitrc), caching is disabled and
cgit instead generates pages to stdout.
The combined effect of these two changes makes testing/debugging a lot
less painfull.

Since fmt() uses 8 alternating static buffers, and cache_lock might call
cache_create_dirs() multiple times, which in turn might call fmt() twice,
after four iterations lockfile would be overwritten by a cachedirectory
path.
In worst case, this could cause the cachedirectory to be unlinked and replaced
by a cachefile.
Fix: use xstrdup() on the result from fmt() before assigning to lockfile, and
call free(lockfile) before exit.

An embarrassing thinko in cgit_check_cache() would truncate valid cachefiles
in the following situation:
1) process A notices a missing/expired cachefile
2) process B gets scheduled, locks, fills and unlocks the cachefile
3) process A gets scheduled, locks the cachefile, notices that the cachefile
now exist/is not expired anymore, and continues to overwrite it with an
empty lockfile.
Thanks to Linus for noticing (again).

Add a global variable, cgit_max_lock_attemps, to avoid the possibility of
infinite loops when failing to acquire a lockfile. This could happen on
broken setups or under crazy server load.
Incidentally, this also fixes a lurking bug in cache_lock() where an
uninitialized returnvalue was used.
