git-svn: fix several corner-case and rare bugs with 'commit'
None of these were really show-stoppers (or even triggered)
on most of the trees I've tracked.
* Node change prevention for identically named nodes. This is
a limitation of SVN, but we find the error and exit before
it's passed to SVN so we don't dirty our working tree when our
commit fails. git-svn will exit with an error code 1 if any
of the following conditions are found:
1. a directory is removed and a file of the same name of the
removed directory is created
1a. a file has its parent directory removed and the file is
takes the name of the removed parent directory::
baz/zzz => baz
2. a file is removed and a directory of the same name of the
removed file is created.
2a. a file is moved into a deeper directory that shares the
previous name of the file::
dir/$file => dir/file/$file
Since SVN cannot handle these cases, the user will have to
manually split the commit into several parts.
* --rmdir now handles nested/deep removals. If dir/a/b/c/d/e/file
is removed, and everything else is in the dir/ hierarchy is
otherwise empty, then dir/ will be deleted when file is deleted
from svn and --rmdir specified.
* Always assert that we have written the tree we want to write
on commits. This helped me find several bugs in the symlink
handling code (which as been fixed).
* Several symlink handling fixes. We now refuse to set
permissions on symlinks. We also always unlink a file
if we're going to overwrite it.
* Apply changes in a pre-determined order, so we always have
rename from locations handy before we delete them.

git-svn: remove any need for the XML::Simple dependency
XML::Simple was originally required back when I made svn-arch-mirror
because I needed to explictly track renames with Arch. Then I carried
it over to git-svn because I was afraid somebody could commit an svn
log message that could throw off a non-XML log parser. Then I noticed
the <n> lines column in the header. So, no more XML :)

This is an Emacs interface for git. The user interface is modeled on
pcl-cvs. It has been developed on Emacs 21 and will probably need some
tweaking to work on XEmacs.
The basic command is 'M-x git-status' which displays a buffer listing
modified files in the selected project tree. In that buffer the
following features are supported:
- add/remove files
- list unknown files
- commit marked files
- manage .gitignore
- commit merges based on MERGE_HEAD
- revert files to the HEAD version
- resolve conflicts with smerge or ediff
- diff files against HEAD/base/mine/other or combined diff
- get a log of the revisions for specified files
There are plenty of unimplemented features too, see the TODO list at
the top of the file...

Make git-reset delete empty directories
When git-reset --hard is used and a subdirectory becomes
empty (as it contains no tracked files in the target tree)
the empty subdirectory should be removed. This matches
the behavior of git-checkout-index and git-read-tree -m
which would not have created the subdirectory or would
have deleted it when updating the working directory.
Subdirectories which are not empty will be left behind.
This may happen if the subdirectory still contains object
files from the user's build process (for example).

git-svn: ensure fetch always works chronologically.
We run svn log against a URL without a working copy for the first fetch,
so we end up a log that's sorted from highest to lowest. That's bad, we
always want lowest to highest. Just default to --revision 0:HEAD now if
-r isn't specified for the first fetch.

Fix object re-hashing
The hashed object lookup had a subtle bug in re-hashing: it did
for (i = 0; i < count; i++)
if (objs[i]) {
.. rehash ..
where "count" was the old hash couny. Oon the face of it is obvious, since
it clearly re-hashes all the old objects.
However, it's wrong.
If the last old hash entry before re-hashing was in use (or became in use
by the re-hashing), then when re-hashing could have inserted an object
into the hash entries with idx >= count due to overflow. When we then
rehash the last old entry, that old entry might become empty, which means
that the overflow entries should be re-hashed again.
In other words, the loop has to be fixed to either traverse the whole
array, rather than just the old count.
(There's room for a slight optimization: instead of counting all the way
up, we can break when we see the first empty slot that is above the old
"count". At that point we know we don't have any collissions that we might
have to fix up any more. This patch only does the trivial fix)

Make "git clone" less of a deathly quiet experience
It used to be that "git-unpack-objects" would give nice percentages, but
now that we don't unpack the initial clone pack any more, it doesn't. And
I'd love to do that nice percentage view in the pack objects downloader
too, but the thing doesn't even read the pack header, much less know how
much it's going to get, so I was lazy and didn't.
Instead, it at least prints out how much data it's gotten, and what the
packing speed is. Which makes the user realize that it's actually doing
something useful instead of sitting there silently (and if the recipient
knows how large the final result is, he can at least make a guess about
when it migt be done).
So with this patch, I get something like this on my DSL line:
where even the speed approximation seems to be roughtly correct (even
though my algorithm is a truly stupid one, and only really gives "speed in
the last half second or so").
Anyway, _something_ like this is definitely needed. It could certainly be
better (if it showed the same kind of thing that git-unpack-objects did,
that would be much nicer, but would require parsing the object stream as
it comes in). But this is big step forward, I think.
