The current 'Not a git repository' error message is not very helpful,
since it doesn't state the cause of the problem.
This patch uses errno to provide a hint of the underlying problem. It
would have been even better to give the exact cause (e.g. for ENOENT it
would be nice to know which file/directory is missing), but that would
require reimplementing setup_git_directory_gently() which seems a bit
overkill.

The old default value was an abomination which never should have been
allowed to see the light of day.
This patch removes the default, which is a backwards incompatible change
with low probability of causing anyone any real trouble (a repo with
submodules, displayed by cgit using the default value of `module-link`,
is very unlikely to actually generate working links).

In ui-plain.c, the links generated for submodule entry ignored the fact
that the entry was in fact a submodule. This patch adds proper submodule
links to the plain directory listings.

The current 'repo.module-link' option is sufficient when all gitlinks
in a repository can be converted to commit links in a uniform way, but
not when different submodules/paths needs different settings.
This patch adds support for 'repo.module-link.<path>', which will be
used for linking to submodules at paths matching one such entry.

The current 'clone-prefix' setting has some known issues:
* All repos get the same 'clone-prefix' value since the setting is not
adopted during repo registration (in cgitrc, or during scan-path traversal),
but only when the setting is used.
* The generated clone-urls for a repo is a combination of 'clone-prefix', a
slash and the repo url. This doesn't work well with e.g. ssh-style urls
like 'git@example.org:repo.git', since the inserted slash will make the
repo relative to the filesystem root.
* If 'remove-suffix' is enabled, the generated clone-urls will not work for
cloning (except for http-urls to cgit itself) since they miss the '.git'
suffix.
The new 'clone-url' setting is designed to avoid the mentioned issues:
* Each repo adopts the default 'clone-url' when the repo is defined. This
allows different groups of repos to adopt different values.
* The clone-urls for a repo is generated by expanding environment variables
in a string template without inserting arbitrary characters, hence any
kind of clone-url can be generated.
* Macro expansion also eases the 'remove-suffix' pain since it's now
possible to define e.g. 'clone-url=git://foo.org/$CGIT_REPO_URL.git' for
a set of repos. A furter improvement would be to define e.g.
$CGIT_REPO_SUFFIX to '.git' for all repos which had their url prettified,
or to store the original $CGIT_REPO_URL in e.g. $CGIT_REPO_REAL_URL before
suffix removal.

When cgit learned to setup environment variables for certain repo
settings before invoking a filter process, the setup occurred inside
cgit_open_filter().
This patch moves the setup out of cgit_open_filter() and into
prepare_repo_cmd() to prepare for additional uses of these variables.

This patch fixes the following issues:
* the base argument usually isn't zero-terminated, so printing base
without considering baselen will usually generate random garbage
* when the current url represents a directory but doesn't end in a slash,
relative urls would be incorrect
* using unescaped paths allows XSS

In d0cb841 (Avoid trailing slash in virtual-root), virtual-root was set
from script-name using trim_end(). However, if script-name was the
empty string (""), which happens when cgit is used to serve the root
path on a domain (/), trim_end() returns NULL and cgit acts like
virtual-root is not available. Now, set virtual-root to "" in this
case, which fixes this bug.

When git/date.c:parse_date() cannot parse its input it returns -1. But
read_agefile() checks if the result is different from zero, essentialy
returning random data from the date buffer when parsing fails. This
patch fixes the issue by verifying that the result from parse_date()
is positive.

reencode() takes three arguments in the order (txt, from, to), opposed to
reencode_string, which will, like iconv, handle the arguments with from
and to swapped. Fix that (this makes reencode more intuitive).
If src and dst encoding are equivalent, don't do any encoding.
If no special encoding parameter is found within the commit, assume
UTF-8 and explicitly convert to PAGE_ENCODING. The change to reencode()
mentioned above avoids re-encoding a UTF-8 string to UTF-8, for example.

This patch makes cgit properly abort in case the projectsfile cannot

pointer which is NULL and thus causes a segfault.
This reintroduces the use of execvp(), since the filter commands doesn't
always contain an absolute path (i.e. snapshot compression filters).
