The resolve_ref() function handles reading of git- and filesystem
symbolic links (including proper whitespace trimming) and packed refs.
There's no point in reimplementing this function in cgit.

There's no need to invoke guess_defbranch() for each repo during
scan-path, since repo.defbranch is only used when repo content is
being displayed.
Also, some users prefer to register their projects manually in cgitrc
but they got no benefit from the new repo.defbranch handling.
This patch tries to rectify these issues by only invoking guess_defbranch()
when needed, regardless of how the repo was registered.

This is a saner alternative than hardcoding the default branch to be
"master". The add_repo() function will now check for a symbolic ref in
repo_path/HEAD. If there is a suitable one, overwrite repo->defbranch
with it. Note that you'll need to strip the newline from the file (->
len-17).
If HEAD is a symbolic link pointing directly to a branch below
refs/heads/, do a readlink() instead to find the ref name.

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 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.
