With the matching Makefile change, this makes sure that only cgit.o and cgit
proper needs to be rebuildt when VERSION has been modified.

Makefile: autobuild dependency rules

This uses gcc to generate dependency rules for each `.o` file, based on the
corresponding `.c` file, into a new set of `.d` files (which are also defined
to depend on the same set of source files as their `.o` files).

Result:
* all objectfile dependencies are correctly calculated
* only the necessary dependencies are recalculated when a sourcefile is updated

Inspiration for the build rules:
* http://www.gnu.org/software/make/manual/make.html#Automatic-Prerequisites
* http://make.paulandlesley.org/autodep.html

while head (as usual) defaults to repo.defbranch. If id2 isn't specified, it
defaults to the first parent of id1.

The most important change is of course that now all repo pages (summary, log,

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

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.

Do not include current path in the "tree" menu link

Include querystring as part of cached filename for repo summary page

When adding support for the h parameter to the summary page (passing current
branch between pages), the builtin cache returned basically random results
for summary page since the cached filename didn't honour the querystring.

This fixes the issue for now, but someday it might be worthwhile to generate
'canonical' filenames in the cache for all pages, i.e. something a bit more
clever than just including the querystring.

Add more menuitems on repo pages

In an attempt to get better usability, a set of 'semistatic' menuitems

The menuitems (summary, log, files, commit and diff) honours the current
branch and revision. To switch the current branch one can use the branch
links on the summary page.

The backlink to the repository index page is now available by clicking
the static page heading.

Support "/" as virtual-root

to removal of trailing slashes, which in turn would fool us to belive that
we shouldn't generate virtual urls.

This makes the "/" normalize to "", effectively allowing virtual urls like
http://example.com/projectname to be generated without specifying the
full domain name as the virtual root.
