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.

Somehow, this option was forgotten when parsing the configfile.
Add it.

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.

This closes the door for unneccessary calls to cgit_fill_cache().

This enables internal caching of page output.
Page requests are split into four groups:
1) repo listing (front page)
2) repo summary
3) repo pages w/symbolic references in query string
4) repo pages w/constant sha1's in query string
Each group has a TTL specified in minutes. When a page is requested, a cached
filename is stat(2)'ed and st_mtime is compared to time(2). If TTL has expired
(or the file didn't exist), the cached file is regenerated.
When generating a cached file, locking is used to avoid parallell processing
of the request. If multiple processes tries to aquire the same lock, the ones
who fail to get the lock serves the (expired) cached file. If the cached file
don't exist, the process instead calls sched_yield(2) before restarting the
request processing.

This enables basic cgit functionality, using libgit.a and xdiff/lib.a from
git + a custom "git.h" + openssl for sha1 routines.
