The original caching layer in cgit has no upper bound on the number of
concurrent cache entries, so when cgit is traversed by a spider (like the
googlebot), the cache might end up filling your disk. Also, if any error
occurs in the cache layer, no content is returned to the client.
This patch redesigns the caching layer to avoid these flaws by
* giving the cache a bound number of slots
* disabling the cache for the current request when errors occur
The cache size limit is implemented by hashing the querystring (the cache
lookup key) and generating a cache filename based on this hash modulo the
cache size. In order to detect hash collisions, the full lookup key (i.e.
the querystring) is stored in the cache file (separated from its associated
content by ascii 0).
The cache filename is the reversed 8-digit hexadecimal representation of
hash(key) % cache_size
which should make the filesystem lookup pretty fast (if directory content
is indexed/sorted); reversing the representation avoids the problem where
all keys have equal prefix.
There is a new config option, cache-size, which sets the upper bound for
the cache. Default value for this option is 0, which has the same effect
as setting nocache=1 (hence nocache is now deprecated).
Included in this patch is also a new testfile which verifies that the
new option works as intended.

By removing the test for commit objects it's now possible to specify a

This creates a generic diffstat function in ui-diff, which then is
invoked from cgit_print_diff with the result that both commit and diff-
view gets a diffstat.

Someone were a bit sloppy when the commitdiff got included 'inline' in
commit 89aa3c0d0a. This patch deletes a
stray `)` and makes sure the diffstat summary `<div>` is closed before
the full diff is printed.

According to the css2 spec, htmlforms have 1.12em top and bottom margins. That

use 0em margins.

* lh/layout:
Make repository search case insensitive
Remove 'patch' link from tab, add to commit view
Implement minimal freetext search in the repolist
More layout fixes
Minor fixup in tree-view css
Reintroduce the branch switcher
Add fixed link to index page from repo header
Include diff in commit view
Replace sidebar/logo
This reuses the strcasestr() compiled or linked by libgit.a to implement a
case insensitive variation of the repository search.

It's a bit confusing to enter the patch view from the tab, since it has no
layout. And the commit view has always lacked showing the commit id. Both of
these warts are fixed by this commit, which adds a new header line in the
commit view which shows the commit id as a 'permalink' to the current commit
and also adds a link to the patch view of the current commit.

But be sure to specify correct filename. This way, the client can hopefully
guess a sensible mimetype based on the filename suffix, and cgit can ignore
the issue altogether.

* lh/cleanup: (21 commits)
Reset ctx.repo to NULL when the config parser is finished
Move cgit_parse_query() from parsing.c to html.c as http_parse_querystring()
Move function for configfile parsing into configfile.[ch]
Add cache.h
Remove global and obsolete cgit_cmd
Makefile: copy the QUIET constructs from the Makefile in git.git
Move cgit_version from shared.c to cgit.c
Makefile: autobuild dependency rules
Initial Makefile cleanup
Move non-generic functions from shared.c to cgit.c
Add ui-shared.h
Add separate header-files for each page/view
Refactor snapshot support
Add command dispatcher
Remove obsolete cacheitem parameter to ui-functions
Add struct cgit_page to cgit_context
Introduce html.h
Improve initialization of git directory
Move cgit_repo into cgit_context
Add all config variables into struct cgit_context
...
This global variable is used by the config parsing callback to keep track
of the currently configured repository. If it is not reset to NULL when
the config parser is finished, and neither `url` or `r` is specified on the
querystring, cgit will wrongly consider the last configured repo as
selected.

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

The snapshot support needs to be split between output- and config-related
functions to get the layering between shared.c and ui-*.c right. There
is also some codestyle-issues which needs fixing to make the snapshot

The code for patch view assumed the current commit would always have a parent,

The earlier segfault in cgit passed by unnoticed by this test-script due to

For some inexplicable reason I'd gotten the semantics of `grep -v` totally
backwards, thinking it somehow would make the exitcode from grep indicate
the non-match of the specified pattern.
This fixes the broken tests and gives me a valuable lession about shell

The segfault fixed in commit eacde43d71 was
triggered when the html-functions manipulated string literals. One callpatch
which could trigger the bug is in ui-repolist.c when repo descriptions are
passed to html_ntxt(): if a repo is lacking a description, the literal
string "[no description]" is used.
This patch changes test/setup.sh such that the first repo has no description,
and adds tests for both "[no description]" and "the bar repo" (description
of the other repo) to tests/t0101-index.sh, which should be enought to catch
regressions in these functions.
