f21d672615 git-apply: war on whitespace -- finishing touches.
This changes the default --whitespace policy to nowarn when we
are only getting --stat, --summary etc. IOW when not applying
the patch.  When applying the patch, the default is warn (spit
out warning message but apply the patch).

2b8d9347aa diff-delta: bound hash list length to avoid O(m*n) behavior
The diff-delta code can exhibit O(m*n) behavior with some patological
data set where most hash entries end up in the same hash bucket.

The latest code rework reduced the block size making it particularly
vulnerable to this issue, but the issue was always there and can be
triggered regardless of the block size.

This patch does two things:

1) the hashing has been reworked to offer a better distribution to
   atenuate the problem a bit, and

2) a limit is imposed to the number of entries that can exist in the
   same hash bucket.

Because of the above the code is a bit more expensive on average, but
the problematic samples used to diagnoze the issue are now orders of
magnitude less expensive to process with only a slight loss in
compression.

In addition to fixing obvious command line parsing bugs in the
previous round, this changes the following:

 * Adds "--whitespace=strip".  This applies after stripping the
   new trailing whitespaces introduced to the patch.

 * The output error message format is changed to say
   "patch-filename:linenumber:contents of the line".  This makes
   it similar to typical compiler error message format, and
   helps C-x ` (next-error) in Emacs compilation buffer.

 * --whitespace=error and --whitespace=warn do not stop at the
   first error.  We might want to limit the output to say first
   20 such lines to prevent cluttering, but on the other hand if
   you are willing to hand-fix after inspecting them, getting
   everything with a single run might be easier to work with.
   After all, somebody has to do the clean-up work somewhere.

This doesn't do the "strip-then-apply" thing, but it allows you to make
git-apply generate a warning or error on extraneous whitespace.

Use --whitespace=warn to warn, and (surprise, surprise) --whitespace=error
to make it a fatal error to have whitespace at the end.

Totally untested, of course. But it compiles, so it must be fine.

HOWEVER! Note that this literally will check every single patch-line with
"+" at the beginning. Which means that if you fix a simple typo, and the
line had a space at the end before, and you didn't remove it, that's still
considered a "new line with whitespace at the end", even though obviously
the line wasn't really new.

I assume this is what you wanted, and there isn't really any sane
alternatives (you could make the warning activate only for _pure_
additions with no deletions at all in that hunk, but that sounds a bit
insane).

stricter. In particular, if there is a "--", then we do not accept any
filenames before it, and if there isn't any "--", then we check that _all_
paths listed are valid, not just the first one.

The new argument parsing automatically also gives us "--default" and

231af8322a Teach the "git" command to handle some commands internally
This is another patch in the "prepare to do more in C" series, where the
git wrapper command is taught about the notion of handling some
functionality internally.

Right now, the only internal commands are "version" and "help", but the
point being that we can now easily extend it to handle some of the trivial
scripts internally. Things like "git log" and "git diff" wouldn't need
separate external scripts any more.

This also implies that to support the old "git-log" and "git-diff" syntax,
the "git" wrapper now automatically looks at the name it was executed as,
and if it is "git-xxxx", it will assume that it is to internally do what
"git xxxx" would do.

In other words, you can (once you implement an internal command) soft- or
hard-link that command to the "git" wrapper command, and it will do the
right thing, whether you use the "git xxxx" or the "git-xxxx" format.

There's one other change: the search order for external programs is
modified slightly, so that the first entry remains GIT_EXEC_DIR, but the
second entry is the same directory as the git wrapper itself was executed
out of - if we can figure it out from argv[0], of course.
