Extend unquote subroutine, which unquotes quoted and escaped filenames
which git may return, to deal not only with octal char sequence
quoting, but also quoting ordinary characters including '\"' and '\\'
which are respectively quoted '"' and '\', and to deal also with
C escape sequences including '\t' for TAB and '\n' for LF.

Add esc_path subroutine for gitweb quoting and HTML escaping filenames
(currently it does equivalent of ls' --hide-control-chars, which means
showing undisplayable characters (including '\n' and '\t') as '?'
(question mark) character, and use 'span' element with cntrl CSS class
to help rendering them differently.

Convert gitweb to use esc_path correctly to print pathnames.

A forked project is defined to be $projname/$forkname.git for
$projname.git; the code did not check this correctly and mistook
$projname/.git to be a fork of itself.  This minimally fixes the
breakage.

Also forks were not checked when index.aux file was in use.
Listing the forked ones in index.aux would show them also on the
toplevel index which may go against the hierarchical nature of
forks, but again this is a minimal fix to whip it in a better
shape suitable to be in the 'master' branch.

Apparently this code was never tested without "forks".  check-feature
returns a one-element list (0) when disabled, and assigning that to a
scalar variable made it to be called in a scalar context, which meant
my $check_forks = gitweb_check_feature("forks") were always 1!

The wt_status_print_updated() and wt_status_print_untracked() routines
call setup_revisions() with 'HEAD' being the reference to the tip of the
current branch. However, setup_revisions() gets confused if the branch
also contains a file named 'HEAD' resulting in a fatal error.

Instead, don't pass an argv to setup_revisions() at all; simply give it no
arguments, and make 'HEAD' the default revision.

If the user has setup a command line of "git --git-dir=baz" then
anything we complete must be performed within the scope of "baz"
and not the current working directory.

This is useful with commands such as "git --git-dir=git.git log m"
to complete out "master" and view the log for the master branch of
the git.git repository.  As a nice side effect this also works for
aliases within the target repository, just as git would honor them.

Unfortunately because we still examine arguments by absolute position
in most of the more complex commands (e.g. git push) using --git-dir
with those commands will probably still cause completion to fail.

Now that Git natively supports remote specifications within the
config file such as:

	[remote "origin"]
		url = ...

we should provide bash completion support "out of the box" for
these remotes, just like we do for the .git/remotes directory.

Also cleaned up the __git_aliases expansion to use the same form
of querying and filtering repo-config as this saves two fork/execs
in the middle of a user prompted completion.  Finally also forced
the variable 'word' to be local within __git_aliased_command.

It turns out that pickaxe reads the same blob repeatedly while
blame can reuse the blob already read for the parent when
handling a child commit when it's parent's turn to pass its
blame to the grandparent.  Have a cache in the origin structure
to keep the blob there, which will be garbage collected when the
origin loses the last reference to it.

  Remove unsupported C99 style struct initializers in git-archive.

  Use ULONG_MAX rather than implicit cast of -1.

At least one older version of the Solaris C compiler doesn't support
the newer C99 style struct initializers.  To allow Git to compile
on those systems use an archive description struct which is easier
to initialize without the C99 struct initializer syntax.

Also since the archives array is not used by anyone other than
archive.c we can make it static.
