The check_snapshot function makes sure that no cruft outside the
repository hierarchy is added to the tar archive. The output from
"tar tf" on the resulting archive is inspected to see if there is
anything that does not begin with "$prefix/".
There are two issues with this implementation:
- Traditional tar implemenations that do not understand
pax_global_header will write it out as if it is a plain file at
the top-level;
- Some implementations of tar do not add trailing slash when
showing a directory entry (i.e. the output line for the entire
archive will show "$prefix", not "$prefix/").
Fix them so that what we want to validate can be tested with
traditional tar implementations.

The title of an RSS feed is generated from many components,
including the filename provided as a query parameter, but we
failed to quote it. Besides showing the wrong output, this
is a vector for XSS attacks.

Extract filtering out forks (which is done if 'forks' feature is
enabled) into filter_forks_from_projects_list subroutine, and
searching projects (via projects search form, or via content tags)
into search_projects_list subroutine.
Both are now run _before_ displaying projects, and not while printing;
this allow to know upfront if there were any found projects. Gitweb
now can and do print 'No such projects found' if user searches for
phrase which does not correspond to any project (any repository).
This also would allow splitting projects list into pages, if we so
desire.
Filtering out forks and marking repository (project) as having forks
is now consolidated into one subroutine (special case of handling
forks in git_get_projects_list only for $projects_list being file is
now removed). Forks handling is also cleaned up and simplified.
$pr->{'forks'} now contains un-filled list of forks; we can now also
detect situation where the way for having forks is prepared, but there
are no forks yet.
Sorting projects got also refactored in a very straight way (just
moving code) into sort_projects_list subroutine.
The interaction between forks, content tags and searching is now made
more explicit: searching whether by tag, or via search form turns off
fork filtering (gitweb searches also forks, and will show all
results). If 'ctags' feature is disabled, then searching by tag is
too.
The t9500 test now includes some basic test for 'forks' and 'ctags'
features; the t9502 includes test checking if gitweb correctly filters
out forks.
Generating list of projects by scanning given directory is now also a
bit simplified wrt. handling filtering; it is byproduct of extracting
filtering forks to separate subroutine.
While at it we now detect that there are no projects and respond with
"404 No projects found" also for 'project_index' and 'opml' actions.

Teach gitweb how to produce nicer snapshot names by only using the
short hash id. If clients make requests using a tree-ish that is not
a partial or full SHA-1 hash, then the short hash will also be appended
to whatever they asked for. If clients request snapshot of a tag
(which means that $hash ('h') parameter has 'refs/tags/' prefix),
use only tag name.
Update tests cases in t9502-gitweb-standalone-parse-output.
Gitweb uses the following format for snapshot filenames:
<sanitized project name>-<version info>.<snapshot suffix>
where <sanitized project name> is project name with '.git' or '/.git'
suffix stripped, unless '.git' is the whole project name. For
snapshot prefix it uses:
<sanitized project name>-<version info>/
as compared to <sanitized project name>/ before (without version info).
Current rules for <version info>:
* if 'h' / $hash parameter is SHA-1 or shortened SHA-1, use SHA-1
shortened to to 7 characters
* otherwise if 'h' / $hash parameter is tag name (it begins with
'refs/tags/' prefix, use tag name (with 'refs/tags/' stripped
* otherwise if 'h' / $hash parameter starts with 'refs/heads/' prefix,
strip this prefix, convert '/' into '.', and append shortened SHA-1
after '-', i.e. use <sanitized hash>-<shortened sha1>

Add t9502-gitweb-standalone-parse-output test script, which runs
gitweb as a CGI script from the commandline and checks that it
produces the correct output.
Currently this test script contains only tests of snapshot naming
(proposed name of snapshot file) and snapshot prefix (prefix of files
in the archive / snapshot). It defines and uses 'tar' snapshot
format, without compression, for easy checking of snapshot prefix.
Testing is done using check_snapshot function.
Gitweb uses the following format for snapshot filenames:
<sanitized project name>-<hash parameter><snapshot suffix>
where <sanitized project name> is project name with '.git' or '/.git'
suffix stripped, unless '.git' is the whole project name. For
snapshot prefix it uses simply:
<sanitized project name>/
Disadvantages of current snapshot rules:
* There exists convention that <basename>.<suffix> archive unpacks to
<basename>/ directory (<basename>/ is prefix of archive). Gitweb
does not respect it
* Snapshot links generated by gitweb use full SHA-1 id as a value of
'h' / $hash parameter. With current rules it leads to long file
names like e.g. repo-1005c80cc11c531d327b12195027cbbb4ff9e3cb.tgz
* For handcrafted URLs, where 'h' / $hash parameter is a symbolic
'volatile' revision name such as "HEAD" or "next" snapshot name
doesn't tell us what exact version it was created from
* Proposed filename in Content-Disposition header should not contain
any directory path information, which means that it should not
contain '/' (see RFC2183)... which means that snapshot naming is
broken for $hash being e.g. hirearchical branch name such as
'xx/test'
This would be improved in next commit.
