git-gui: Fix parsing of <rev> <path-which-not-present-in-worktree>

Commit e3d06ca9 (git-gui: Detect full path when parsing arguments) broke

    git gui blame rev path-not-present-in-worktree

in particular this does not work anymore:

    # in linux.git
    $ git gui blame 2bb8c26242c2393b097a993ffe9b003ec9b85395 drivers/net/sky2.c

This patch restores the original functionality in this case.

simplify-merges: drop merge from irrelevant side branch

The merge simplification rule stated in 6546b59 (revision traversal:
show full history with merge simplification, 2008-07-31) still
treated merge commits too specially.  Namely, in a history with this
shape:

	---o---o---M
	          /
         x---x---x

where three 'x' were on a history completely unrelated to the main
history 'o' and do not touch any of the paths we are following, we
still said that after simplifying all of the parents of M, 'x'
(which is the leftmost 'x' that rightmost 'x simplifies down to) and
'o' (which would be the last commit on the main history that touches
the paths we are following) are independent from each other, and
both need to be kept.

That is incorrect; when the side branch 'x' never touches the paths,
it should be removed to allow M to simplify down to the last commit
on the main history that touches the paths.

config.mak.in: remove unused definitions

When 5566771 (autoconf: Use autoconf to write installation
directories to config.mak.autogen, 2006-07-03) introduced support
for autoconf generated config.mak file, it added an "export" for a
few common makefile variables, in addition to definitions of srcdir
and VPATH.

The "export" logically does not belong there.  The make variables
like mandir, prefix, etc, should be exported to submakes for people
who use config.mak and people who use config.mak.autogen the same
way; if we want to get these exported, that should be in the main
Makefile.

We do use mandir and htmldir in Documentation/Makefile, so let's
add export for them in the main Makefile instead.

We may eventually want to support VPATH, and srcdir may turn out to
be useful for that purpose, but right now nobody uses it, so it is
useless to define them in this file.

pack-objects: shrink struct object_entry

Git.pm: allow command_close_bidi_pipe to be called as method

The documentation of command_close_bidi_pipe() claims that it can
be called as a method, but it does not check whether the first
argument is $self or not assuming the latter.  Using _maybe_self()
fixes this.

parse_fetch_refspec(): clarify the codeflow a bit

fetch: use struct ref to represent refs to be fetched

Even though "git fetch" has full infrastructure to parse refspecs to
be fetched and match them against the list of refs to come up with
the final list of refs to be fetched, the list of refs that are
requested to be fetched were internally converted to a plain list of
strings at the transport layer and then passed to the underlying
fetch-pack driver.

Stop this conversion and instead pass around an array of refs.

upload-pack: optionally allow fetching from the tips of hidden refs

With uploadpack.allowtipsha1inwant configuration option set, future
versions of "git fetch" that allow an exact object name (likely to
have been obtained out of band) on the LHS of the fetch refspec can
make a request with a "want" line that names an object that may not
have been advertised due to transfer.hiderefs configuration.
