Frontend clients can now send a text stream to fast-import rather
than a binary stream.  This should facilitate developing frontend
software as the data stream is easier to view, manipulate and debug
my hand and Mark-I eyeball.

When accepting revision SHA1 IDs from the frontend verify the SHA1
actually refers to a blob and is known to exist.  Its an error
to use a SHA1 in a tree if the blob doesn't exist as this would
cause git-fsck-objects to report a missing blob should the pack get
closed without the blob being appended into it or a subsequent pack.
So right now we'll just ask that the frontend "pre-declare" any
blobs it wants to use in a tree before it can use them.

The tree of the current commit can be altered by file_change commands
before the commit gets written to the pack.  The file changes are
rather primitive as they simply allow removal of a tree entry or
setting/adding a tree entry.

Currently trees and commits aren't being deltafied when written to
the pack and branch reloading from the current pack doesn't work,
so at most 5 branches can be worked with at any one time.

This provides the basic data structures needed to store trees in
memory while we are processing them for a branch.  What we are
attempting to do is track one complete tree for each branch that
the frontend has registered with us through the 'newb' (new_branch)
command.  When the frontend edits that tree through 'updf' or 'delf'
commands we'll mark the affected tree(s) as being dirty and recompute
their objects during 'comt' (commit).

Currently the protocol is decidedly _not_ user friendly.  I crashed
fast-import by giving it bad input data from Perl.  I may try to
improve upon it, or at least upon its error handling.

Moved the new_blob logic off into a new subroutine and
invoked it when getting the 'blob' command.

Added statistics dump to STDERR when the program terminates listing
what it did at a high level.  This is somewhat interesting.

Too many globals variables were being used not not enough
code was resuable to process trees and commits so this is
a simple refactoring of the existing blob processing code
to get into a state that will be easier to handle trees
and commits in.

Although its easy to ask the user to tell us how many objects they
will need, its probably better to dynamically grow the object table
in large units.  But if the user can give us a hint as to roughly
how many objects then we can still use it during startup.

Also stopped printing the SHA1 strings to stdout as no user is
currently making use of that facility.

In the same spirit as hashcmp() and hashcpy().
Signed-off-by: NJunio C Hamano <junkio@cox.net>

This abstracts away the size of the hash values when copying them
from memory location to memory location, much as the introduction
of hashcmp abstracted away hash value comparsion.

A few call sites were using char* rather than unsigned char* so
I added the cast rather than open hashcpy to be void*.  This is a
reasonable tradeoff as most call sites already use unsigned char*
and the existing hashcmp is also declared to be unsigned char*.

[jc: Splitted the patch to "master" part, to be followed by a
 patch for merge-recursive.c which is not in "master" yet.

 Fixed the cast in the latter hunk to combine-diff.c which was
 wrong in the original.

 Also converted ones left-over in combine-diff.c, diff-lib.c and
 upload-pack.c ]

When an mbox-style patch contains a Cc: line in the header,
git-send-email will check the address against the sender specified
on the command line. If they don't match, sender_not_author will
be set to the address obtained from the Cc line.

When this happens, git-send-email inserts a From: line at the
beginning of the message body with the address obtained from the
Cc line in the header, and the sender might be accused of forging
patch authors.

This patch fixes this by only updating sender_not_author when
processing From: lines, not when processing Cc: lines.

If the pack format were to ever change or be extended in the future
there is no assurance that just because the pack file lives in
objects/pack and doesn't end in .idx that we can read and decompress
its contents properly.

If we encounter what we think is a pack file and it isn't or we don't
recognize its version then die and suggest to the user that they
upgrade to a newer version of GIT which can handle that pack file.

The little helper write_or_die() won't come back with bad news about
full disks or broken pipes.  It either succeeds or terminates the
program, making additional error handling unnecessary.

This patch adds the new function and uses it to replace two similar
ones (the one in tar-tree originally has been copied from cat-file
btw.).  I chose to add the fd parameter which both lacked to make
write_or_die() just as flexible as write() and thus suitable for
lib-ification.

There is a regression: error messages emitted by this function don't
show the program name, while the replaced two functions did.  That's
acceptable, I think; a lot of other functions do the same.

Add support for showing multiple clone/fetch git URLs for project on
a summary page. URL for project is created from base URL and project
name.

For example for XMMS2 project (xmms.se) the git base URL would be
