Allow to have project name in the path part of URL, just after the name of

Not used in URLs inside gitweb; it means that the above alternate syntax

Side effect: project name parameter is now stripped of leading and
trailing slash before validation.

recursive merge relies on Python, and we can't perform
rename-aware merges without the recursive merge.  So bail out
before trying it.

The test won't work w/o recursive merge, either, so skip that,
too.

This does not implement sideband for propagating the status to

output from the pack-objects process in preparation for sending

so.

When the repository on the remote side is corrupted, rev-list
spawned from upload-pack would die with error, but pack-objects
that reads from the rev-list happily created a packfile that can
be unpacked by the downloader.  When this happens, the resulting
packfile is not corrupted and unpacks cleanly, but the list of
the objects contained in it is not what the protocol exchange
computed.

This update makes upload-pack to monitor its subprocesses, and
when either of them dies with error, sends an incomplete pack
data to the downloader to cause it to fail.

* master:
  checkout -f: do not leave untracked working tree files.
  Log peer address when git-daemon called from inetd

Earlier we did not consider untracked working tree files
"precious", but we have always considered them fair game to
clobber.  These days, branch switching by read-tree is more
careful and tries to protect untracked working tree files.  This
caused the following workflow to stop working:

	git checkout one-branch-with-file-F
	git checkout -f another-without-file-F
	git pull . one-branch-with-file-F

Because the second checkout leaves F from the previous state as
untracked file in the working tree, the merge would fail, trying
to protect F from being clobbered.

This changes "git checkout -f" to remove working tree files that
are known to git in the switched-from state but do not exist in
the switched-to state, borrowing the same logic from "reset --hard".

When we run git-daemon from inetd, even with the --verbose option, it
doesn't log the peer address. That logic was only in the standalone
daemon code -- move it to the execute() function instead. Tested with
both IPv6 and Legacy IP clients, in both inetd and daemon mode.

We've had this notion of a "object_list" for a long time, which eventually
grew a "name" member because some users (notably git-rev-list) wanted to
name each object as it is generated.

That object_list is great for some things, but it isn't all that wonderful
for others, and the "name" member is generally not used by everybody.

This patch splits the users of the object_list array up into two: the
traditional list users, who want the list-like format, and who don't
actually use or want the name. And another class of users that really used
the list as an extensible array, and generally wanted to name the objects.

The patch is fairly straightforward, but it's also biggish. Most of it
really just cleans things up: switching the revision parsing and listing
over to the array makes things like the builtin-diff usage much simpler
(we now see exactly how many members the array has, and we don't get the
objects reversed from the order they were on the command line).

One of the main reasons for doing this at all is that the malloc overhead
of the simple object list was actually pretty high, and the array is just
a lot denser. So this patch brings down memory usage by git-rev-list by
just under 3% (on top of all the other memory use optimizations) on the
mozilla archive.

It does add more lines than it removes, and more importantly, it adds a
whole new infrastructure for maintaining lists of objects, but on the
other hand, the new dynamic array code is pretty obvious. The change to
builtin-diff-tree.c shows a fairly good example of why an array interface
is sometimes more natural, and just much simpler for everybody.

It was reported that under one implementation of socks client
"git clone" fails with "error: waitpid failed (No child processes)",
because "git" is spawned after setting SIGCHLD to SIG_IGN.

Arguably it may be a broken setting, but we should protect
ourselves so that we can get reliable results from waitpid() for
the children we care about.

This patch resets SIGCHLD to SIG_DFL in three places:

 - connect.c::git_connect() - initiators of git native
   protocol transfer are covered with this.

 - daemon.c::main() - obviously.

 - merge-index.c::main() - obviously.

There are other programs that do fork() but do not waitpid():
http-push, imap-send.  upload-pack does not either, but in the
case of that program, each of the forked halves runs exec()
another program, so this change would not have much effect
there.
