This adds a function to generate links to the commit page and extends said
page to use id from querystring as primary revision specified (fallback to
h).

This teaches ui-tree to show both trees and blobs, thereby making ui-view
superfluous. At the same time, ui-tree is extended to honour the specified
path instead of requiering a tree/blob sha1.
This makes is possible to use repo-urls like '/pub/scm/git/git.git' and
even add path specifications, like '/pub/scm/git/git.git/log/documentation'.

The commitdiff will be generated against the first parent, and the
diff page also gets the benefit of repo.defbranch.
Cleaned up some bad whitespace in cgit.h while at it.

Pages which expect head to be specified in the querystring can now be
given a default value, configurable per repository (via repo.defbranch,
which defaults to "master").
Currently, only the log page actually works without parameters, but the
defbranch is bound to be exploited.
This also removes some dead code from shared.c

This enables path-filtering in log-view, and adds a link per entry in

A link is added next to each parent of a commit, leading to the new
diff-functionality in ui-diff.c.
Also added support for a path-parameter to filelevel diffs accessed via the
diffstat.

This enabled customizing number of commits shown per page in log view. It
also changes the default from 100 to 50, mainly due to the more cpu
intensive log pages (number of files/lines changed) but also since 100
log messages requires excessive scrolling.

Snapshots can now be enabled/disabled by default for all repositories in
cgitrc with param "snapshots". Additionally, any repo can override the
default setting with param "repo.snapshots".
By default, no snapshotting is enabled.

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
repo.url=cgit-priv
repo.name=cgit/private
repo.path=/home/larsh/src/cgit/.git
repo.desc=My private cgit repo
repo.owner=Lars Hjemli

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.

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 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.
