The change to print_slot() in cdc6b2f8e7a8d43dcfe0475a9d3498333ea686b8 made
the function return correct errno for read errors while ignoring write errors,
which is not what was intended. This patch tries to rectify things.

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).

These functions handles EINTR/EAGAIN errors during read/write operations,
which is something cache.c didn't.
While at it, fix a bug in print_slot() where errors during reading from the
cache slot might go by unnoticed.

We'll need proper return-values from these functions to make the cache
behave correctly (which includes giving proper error messages).

Both cgit_print_diff() and cgit_diff_tree() handles root commits nicely,
but cgit_print_commit() forgot to check the case of 0 parents.
This fixes it, and adds tests to avoid future regressions.

This makes it more obvious how to get back to the index, especially when the
config option `logo-link` is used. And the page name displayed in the header
provided no extra information. It only consumed space and deserved to die.
While at it, make sure that the different parts of the header doesn't wrap
when horizontal space is limited.

When cgit_cmd.want_repo was 0, we used to assume that the cmd would never
be invoked for a repo. But soon this will become untrue (the 'about' cmd
is rapidly approching), so from now on we will initialize any requested
repo even if want_repo==0 (and return an error if want_repo==1 but no repo
is specified).

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.

When the 'index-header' option is specified in cgitrc we used to print

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.

Someone were a bit sloppy when the commitdiff got included 'inline' in
commit 89aa3c0d0a4c6d9885272602005975b763ea1604. This patch deletes a
stray `)` and makes sure the diffstat summary `<div>` is closed before
the full diff is printed.

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.

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.
