This trivial patch not only simplifies the name hashing, it actually
improves packing for both git and the kernel.
The git archive pack shrinks from 6824090->6622627 bytes (a 3%
improvement), and the kernel pack shrinks from 108756213 to 108219021 (a
mere 0.5% improvement, but still, it's an improvement from making the
hashing much simpler!)
We just create a 32-bit hash, where we "age" previous characters by two
bits, so the last characters in a filename count most. So when we then
compare the hashes in the sort routine, filenames that end the same way
sort the same way.
It takes the subdirectory into account (unless the filename is > 16
characters), but files with the same name within the same subdirectory
will obviously sort closer than files in different subdirectories.
And, incidentally (which is why I tried the hash change in the first
place, of course) builtin-rev-list.c will sort fairly close to rev-list.c.
And no, it's not a "good hash" in the sense of being secure or unique, but
that's not what we're looking for. The whole "hash" thing is misnamed
here. It's not so much a hash as a "sorting number".
[jc: rolled in simplification for computing the sorting number
computation for thin pack base objects]

git-svnimport: Improved detection of merges.

The earlier "git reset --hard" simplification stopped removing
leftover working tree files from a failed automerge, when
switching back to the HEAD version that does not have the
paths.
This patch, instead of removing the unmerged paths from the
index, drops them down to stage#0 but marks them with mode=0
(the same "to be deleted" marker we internally use for paths
deleted by the merge). one_way_merge() function and the
functions it calls already know what to do with them -- if the
tree we are reading has the path the working tree file is
overwritten, and if it doesn't the working tree file is
removed.

This function reads a freshly fetched tree object, and schedules
the objects pointed by it for further fetching, so doing
lookup_tree() and process_tree() recursively from there does not
make much sense. We need to use process() on it to make sure we
fetch it first, and leave the recursive processing to later
stages.

When adding packs, skip the pack if we already have it in the packed_git

This patch causes read_sha1_file and sha1_object_info to re-examine the
list of packs if an object cannot be found. It works by re-running
prepare_packed_git() after an object fails to be found.
It does not attempt to clean up the old pack list. Old packs which are in
use can continue to be used (until unused by lru selection). New packs
are placed at the front of the list and will thus be examined before old
packs.

If a curl handle is configured with special options, they may reference
information that is freed after the request is complete which can cause
a segfault if the curl handle is reused for a different type of request.
This patch resets these options to a safe state when a transfer slot is
assigned to a new request.

I find it very convenient to be able to supply multiple paragraphs
of text on the command line with a single git-commit call. This
change permits multiple -m/--message type options to be supplied
to git-commit with each message being added as its own paragraph
of text in the commit message.
The -m option is still not permitted with -c/-C/-F nor are multiple
occurrences of these options permitted.

The regexes detecting merges (while still relying on the commit messages,
though) have been improved to catch saner (and hopefully more) messages. The
old regex was so generic that it often matched something else and missed the
actual merge-message.
Also, the regex given with the `-M' commandline-option is checked first:
Explicitely given regexes should be considered better than the builtin ones,
and should therefore be given a chance to match a message first.

This adds a "tree_entry()" function that combines the common operation of
doing a "tree_entry_extract()" + "update_tree_entry()".
It also has a simplified calling convention, designed for simple loops
that traverse over a whole tree: the arguments are pointers to the tree
descriptor and a name_entry structure to fill in, and it returns a boolean
"true" if there was an entry left to be gotten in the tree.
This allows tree traversal with
struct tree_desc desc;
struct name_entry entry;
desc.buf = tree->buffer;
desc.size = tree->size;
while (tree_entry(&desc, &entry) {
... use "entry.{path, sha1, mode, pathlen}" ...
}
which is not only shorter than writing it out in full, it's hopefully less
error prone too.
[ It's actually a tad faster too - we don't need to recalculate the entry
pathlength in both extract and update, but need to do it only once.
Also, some callers can avoid doing a "strlen()" on the result, since
it's returned as part of the name_entry structure.
However, by now we're talking just 1% speedup on "git-rev-list --objects
--all", and we're definitely at the point where tree walking is no
longer the issue any more. ]
NOTE! Not everybody wants to use this new helper function, since some of
the tree walkers very much on purpose do the descriptor update separately
from the entry extraction. So the "extract + update" sequence still
remains as the core sequence, this is just a simplified interface.
We should probably add a silly two-line inline helper function for
initializing the descriptor from the "struct tree" too, just to cut down
on the noise from that common "desc" initializer.
