Import cgit prototype from git tree This enables basic cgit functionality, using libgit.a and xdiff/lib.a from git + a custom "git.h" + openssl for sha1 routines. Signed-off-by: Lars Hjemli <hjemli@gmail.com>

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. Signed-off-by: Lars Hjemli <hjemli@gmail.com>

Add a common commit parser Make a better commit parser, replacing the ugly one in ui-log.c Signed-off-by: Lars Hjemli <hjemli@gmail.com>

Teach commit parser about author/committer email + timestamp 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. Signed-off-by: Lars Hjemli <hjemli@gmail.com>

Add argument parsing + switch for uncached operation 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.

Avoid infinite loops in caching layer 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.
