cgit_print_http_headers() used to do nothing if 'embedded' was
specified in cgitrc, but that was wrong - we never want to skip the
headers when invoked as a CGI app. Sadly, there's no easy way to
detect if we're invoked as a CGI app or if we're invoked by another
CGI app, so for the latter case cgit needs to be invoked with either
--nohttp on the command line or NO_HTTP=1 in the environment.

This new option specifies a filter which is executed on the commit
message, i.e. the commit message is written to the filters STDIN and
the filters STDOUT is included verbatim as the commit message.
This can be used to implement commit linking by creating a simple
shell script in e.g. /usr/bin/cgit-commit-filter.sh like this:
#/bin/sh
sed -re 's|\b([0-9a-fA-F]{6,40})\b|<a href="./?id=\1">\1</a>|g'

This patch makes it possible to register mappings from filename
extension to mime type in cgitrc and use this mapping when returning
blob content in `plain` view.
The reason for adding this mapping to cgitrc (as opposed to parsing
something like /etc/mime.types) is to allow quick lookup of a limited
number of filename extensions (/etc/mime-types on my machine currently
contains over 700 entries).
NB: A nice addition to this patch would be to parse /etc/mime.types
when `plain` view is requested for a file with an extension for which
there is no mapping registered in cgitrc.

This patch adds an option to the configuration file, "head-include",
which works just like "header" or "footer", except the content is put
into the HTML's <head> tag.
When downloading a blob identified by its path, the client might want
to know if the blob has been modified since a previous download of the
same path. To this end, an ETag containing the blob SHA1 seems to be
ideal.
Todo: add support for HEAD requests...

When activated, cgit will neither generate http headers nor any 'framing'
html elements (like <html> and <body>). Also, all page content is now
wrapped in a <div id='cgit'> element to make it easier to select the
correct cgit classes when embedded/themed.

When an unknown page is requested, either on the querystring or via
PATH_INFO, we end up with a null-referencing cgit_cmd. This null-
pointer is then used as argument to the hc() function (which decides
what tab to render as 'active'), but this function failed to check if a
valid cmd was specified and a SEGFAULT would occur. This patch fixes the
issue by introducing a 'fallback-cmd' which specifies what tab to render
as 'active' when no valid cmd is requested.
While at it, we now also keep track of the active repository even if an
invalid cmd was requested since we want to show the error message about
the invalid request in the correct context.

SCRIPT_NAME is used as fallback for virtual-root when virtual-root is
unspecified in cgitrc and PATH_INFO is used as fallback for the query-
string parameter 'url' when the latter is unspecified. But until now,
the use of PATH_INFO depended on virtual-root also being unspecified,
i.e. it was impossible to use PATH_INFO when virtual-root was specified.
This commit makes the fallback on SCRIPT_NAME and PATH_INFO independent
code paths, i.e. it is now possible to specify virtual-root in cgitrc
while still using PATH_INFO (instead of rewrite rules) to get 'pretty
urls'.

This new page, which is disabled by default, can be used to print some
statistics about the number of commits per period in the repository,
where period can be either weeks, months, quarters or years.
The function can be activated globally by setting 'enable-stats=1' in
cgitrc and disabled for individual repos by setting 'repo.enable-stats=0'.

Some users prefer to see the full message, so to make these users happy
the new querystring parameter "showmsg" can be used to print the full
commit message per log entry.
A link is provided in the log heading to make this function accessible,
and all links and forms tries to preserve the users preference.
Note: the new link is not displayed on the summary page since the point
of the summary page is to be a summary, but it is still obeyed if specified
manually.

This commit makes cgit use the cgi variables SCRIPT_NAME and PATH_INFO
when virtual-root is unspecified in cgitrc and no url-parameter is

* Virtual urls works out of the box, no more need for rewrite-rules in httpd.
* Virtual urls with special querystring characters are handled correctly.

If print_slot() fails, the client will be served an inferior response.
This patch makes sure that such an error will be returned to main(), which
in turn will try to inform about the error in the response itself.
The error is also printed to the cache_log, i.e. stderr, which will make
the error message appear in error_log (atleast when httpd==apache).

The 'index-info' option got lost when the layout was converted from
sidebar to old-fashioned header (noticed by Harley Laue, thanks!), and
this commit re-enables it.
But there is now also an alternative in the 'root-desc' option; where
'index-info' specifies a file to include, 'root-desc' specifies the text
literally. This might be nicer for the one-liner descriptions which these
options typically provides.

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.
