Avoid wrong disambiguation that would link logs/trees of tags and
heads which share the same name to the same page, leading to
a disambiguation that would prefer the tag, thus making it impossible
to access the corresponding head log and tree without hacking the url
by hand.
It does it by using full refname (with 'refs/heads/' or 'refs/tags/'
prefix) instead of shortened one in the URLs in 'heads' and 'tags'
tables. This makes URLs (and refs) provided by gitweb unambiguous.

Change git_get_project_config to run git-config only once per
repository, without changing its signature (its calling convention).
This means for example that it returns 'true' or 'false' when called
with second argument '--bool', and not true or false value.
Instead of calling 'git config [<type>] --get gitweb.<key>' once for
each config variable, call 'git config -z -l' only once, parsing and
saving its output to %config variable. This makes possible to add new
per repository configuration without paying cost of forking once per
variable checked. We can now allow repository description and
repository URLs to be stored in config file without badly affecting
gitweb performance.
For now only configuration variables for 'gitweb' section are stored.
Multiple values for single configuration variable are stored as
anonymous array reference; configuration variable with no value is
stored as undef.
Converting configuration variable values to boolean or integer value
are done in Perl. Results differ from git-config in the fact that no
conversion error is ever raised. For boolean values no value, 'true'
(any case) and 'false' (any case) are considered true, numbers are
true if not zero; all other values (even invalid for bool) are
considered false. For integer values value suffix of 'k', 'm', or 'g'
following decimal number will cause the value to be multiplied by
1024, 1048576, or 1073741824; other values are returned as-is, only
whitespace stripped.

There are some cases when one line from "raw" git-diff output (raw
format) corresponds to more than one patch in the patchset git-diff
output; we call this situation "split patch". Old code misdetected
subsequent patches (for different files) with the same pre-image and
post-image as fragments of "split patch", leading to mislabeled
from-file/to-file diff header etc.
Old code used pre-image and post-image SHA-1 identifier ('from_id' and
'to_id') to check if current patch corresponds to old raw diff format
line, to find if one difftree raw line coresponds to more than one
patch in the patch format. Now we use post-image filename for that.
This assumes that post-image filename alone can be used to identify
difftree raw line. In the case this changes (which is unlikely
considering current diff engine) we can add 'from_id' and 'to_id'
to detect "patch splitting" together with 'to_file'.
Because old code got pre-image and post-image SHA-1 identifier for the
patch from the "index" line in extended diff header, diff header had
to be buffered. New code takes post-image filename from "git diff"
header, which is first line of a patch; this allows to simplify
git_patchset_body code. A side effect of resigning diff header
buffering is that there is always "diff extended_header" div, even
if extended diff header is empty.
Alternate solution would be to check when git splits patches, and do
not check if parsed info from current patch corresponds to current or
next raw diff format output line. Git splits patches only for 'T'
(typechange) status filepair, and there always two patches
corresponding to one raw diff line. It was not used because it would
tie gitweb code to minute details of git diff output.
While at it, use newly introduced parsed_difftree_line wrapper
subroutine in git_difftree_body.

If somebody used to advertise his repository that physically
resides at /pub/lic.git/ as:
git://git.example.com/pub/lic.git/
but now wants to use --base-path to allow:
git://git.example.com/lic.git/
she can start git-daemon with --base-path option, like this:
git-daemon --base-path=/pub --export-all
During the transition, however, she would also want to allow
older URL as well. One natural way to achieve that is to create
a symlink:
ln -s /pub /pub/pub
so that a request to git://git.example.com/pub/lic.git/ is first
translated by --base-path to a request to /pub/pub/lic.git/
which goes to /pub/lic.git, thanks to the symlink.
So far so good.

Earlier commit which cleaned up snapshot support and introduced
support for multiple snapshot formats changed the format of
$feature{'snapshot'}{'default'} (gitweb configuration) and
gitweb.snapshot configuration variable (repository configuration).
It supported old gitweb.snapshot values of 'gzip', 'bzip2' and 'zip'
and tried to support, but failed to do that, old values of
$feature{'snapshot'}{'default'}; at least those corresponding to
old gitweb.snapshot values of 'gzip', 'bzip2' and 'zip', i.e.
['x-gzip', 'gz', 'gzip']
['x-bzip2', 'bz2', 'bzip2']
['x-zip', 'zip', '']
This commit moves legacy configuration support out of feature_snapshot
subroutine to separate filter_snapshot_fmts subroutine. The
filter_snapshot_fmts is used on result on result of
gitweb_check_feature('snapshot'). This way feature_snapshot deals
_only_ with repository config.
As a byproduct you can now use 'gzip' and 'bzip2' as aliases to 'tgz'
and 'tbz2' also in $feature{'snapshot'}{'default'}, not only in
gitweb.snapshot.
While at it do some whitespace cleanup: use tabs for indent, but

- Centralize knowledge about snapshot formats (mime types, extensions,

information is specified. In particular, zip files are no longer a
special case.
- Add support for offering multiple snapshot formats to the user so
that he/she can download a snapshot in the format he/she prefers.
The site-wide or project configuration now gives a list of formats
to offer, and if more than one format is offered, the "_snapshot_"
link becomes something like "snapshot (_tar.bz2_ _zip_)".
- If only one format is offered, a tooltip on the "_snapshot_" link
tells the user what it is.
- Fix out-of-date "tarball" -> "archive" in comment.
Alert for gitweb site administrators: This patch changes the format of
$feature{'snapshot'}{'default'} in gitweb_config.perl from a list of
three pieces of information about a single format to a list of one or
more formats you wish to offer from the set ('tgz', 'tbz2', 'zip').
Update your gitweb_config.perl appropriately. There was taken care
for old-style gitweb configuration to work as it used to, but this
backward compatibility works only for the values which correspond to
gitweb.snapshot values of 'gzip', 'bzip2' and 'zip', i.e.
['x-gzip', 'gz', 'gzip']
['x-bzip2', 'bz2', 'bzip2']
['x-zip', 'zip', '']
The preferred names for gitweb.snapshot in repository configuration
have also changed from 'gzip' and 'bzip2' to 'tgz' and 'tbz2', but

About patchset part of diff --cc output: the difftree (whatchanged
table) has "patch" links to anchors to individual patches (on the same
page). The --cc option further compresses the patch output by
omitting some hunks; when this optimization makes all hunks disappear,
the patch is not shown (like in any other "empty diff" case). But the
fact that patch has been simplified out is not reflected in the raw
(difftree) part of diff output; the raw part is the same for '-c' and
'--cc' options. As correcting difftree is rather out of the question,
as it would require scanning patchset part before writing out
difftree, we add "Simple merge" empty diffs as a place to have anchor

Since commit-fb1dde4a we show combined diff for merges in 'commitdiff'
view, and since commit-208ecb2e also in 'commit' view. Sometimes
though one would want to see diff to one of merge commit parents. It
is easy in 'commit' view: in the commit header part there are "diff"
links for each of parent header. This commit adds such links also for
'commitdiff' view.
Add to difftree / whatchanged table row with "1", "2", ... links to
'commitdiff' view for diff with n-th parent for merge commits, as a
table header. This is visible only in 'comitdiff' view, and only for
a merge commit (comit with more than one parent).
To save space links are shown as "n", where "n" is number of a parent,
and not as for example shortened (to 7 characters) sha1 of a parent
commit. To make it easier to discover what links is for, each link
has 'title' attribute explaining the link.
Note that one would need to remember that difftree table in 'commit'
view has one less column (it doesn't have "patch" link column), if one
would want to add such table header also in 'commit' view.
