This patch implements read_tree_with_tree_or_commit_sha1(),
which can be used when you are interested in reading an unpacked
raw tree data but you do not know nor care if the SHA1 you
obtained your user is a tree ID or a commit ID. Before this
function's introduction, you would have called read_sha1_file(),
examined its type, parsed it to call read_sha1_file() again if
it is a commit, and verified that the resulting object is a
tree. Instead, this function does that for you. It returns
NULL if the given SHA1 is not either a tree or a commit.

This adds --stage option to show-files command. It shows
file-mode, SHA1, stage and pathname. Record separator follows
the usual convention of -z option as before.

The ce_namelen field has been renamed to ce_flags and split into
the top 2-bit unused, next 2-bit stage number and the lowest
12-bit name-length, stored in the network byte order. A new
macro create_ce_flags() is defined to synthesize this value from
length and stage, but it forgets to turn the value into the
network byte order. Here is a fix.

This allows using a git tree over NFS with different byte order, and
makes it possible to just copy a fully populated repository and have
the end result immediately usable (needing just a refresh to update
the stat information).
Now there is error() for "library" errors and die() for fatal "application"
errors. usage() is now used strictly only for usage errors.

It now requires the "--add" flag before you add any new files, and
a "--remove" file if you want to mark files for removal. And giving
it the "--refresh" flag makes it just update all the files that it
already knows about.
It's got some debugging printouts etc still in it, but testing on the
kernel seems to show that it does indeed fix the issue with huge tree
files for each commit.
It finds the cache entry position for a given name, and is
generally useful. Sure, everybody can just scan the active
cache array, but since it's sorted, you actually want to
search it with a binary search, so let's not duplicate that
logic all over the place.
Patches from Dave Jones and Ingo Molnar, but since I don't have any
infrastructure in place to use the old patch applicator scripts I
am trying to build up, I ended up fixing the thing by hand instead.
Credit where credit is due, though. Nice to see that people are
taking a look at the project even in this early stage.
