Read repo-info from /etc/cgitrc

This makes cgit read all repo-info from the configfile, instead of scanning for
possible git-dirs below a common root path. This is primarily done to get
better security (separate physical path from logical repo-name).

In /etc/cgitrc each repo is registered with the following keys:

repo.url
repo.name
repo.path
repo.desc
repo.owner

Note:

*Required keys are repo.url and repo.path, all others are optional
*Each occurrence of repo.url starts a new repository registration
*Default value for repo.name is taken from repo.url
*The value of repo.url cannot contain characters with special meaning for
 urls (i.e. one of /?%&), while repo.name can contain anything.

Example:

repo.url=cgit-pub
repo.name=cgit/public
repo.path=/pub/git/cgit
repo.desc=My public cgit repo
repo.owner=Lars Hjemli

cache_lock: do xstrdup/free on lockfile

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.

call free(lockfile) before exit.

Add caching infrastructure

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.

Don't be fooled by trailing '/' in url-parameter

cgit_parse_url() didn't check if the path-part of urls contained a
real path or just a trailing slash. This made the log-page die since
the path filtering supplied an invalid path argument. This fixes it.

cache_safe_filename() needs more buffers

The single static buffer makes it impossible to use the result of two
different calls to this function simultaneously. Fix it by using 4
buffers.

Teach cgit how to group repositories by category

The new parameter 'repo.group' is used to set the repository group
for the following repositores. Whenever this parameter changes value,
a subheading is generated in the index page (printing the current value
of repo.group).
