If the gain is not obvious in the diffstat, the resulting code is more
readable, _and_ in checkout-index/update-index we now reuse the same buffer
to unquote strings instead of always freeing/mallocing.
This also is more coherent with the next patch that reworks quoting
functions.
The quoting function is also made more efficient scanning for backslashes
and treating portions of strings without a backslash at once.

We always quote "unusual" byte values in a pathname using
C-string style, to make it safer for parsing scripts that do not
handle NUL separated records well (or just too lazy to bother).
The absolute minimum bytes that need to be quoted for this
purpose are TAB, LF (and other control characters), double quote
and backslash.
However, we have also always quoted the bytes in high 8-bit
range; this was partly because we were lazy and partly because
we were being cautious.
This introduces an internal "quote_path_fully" variable, and
core.quotepath configuration variable to control it. When set
to false, it does not quote bytes in high 8-bit range anymore
but passes them intact.
The variable defaults to "true" to retain the traditional
behaviour for now.

Love it or hate it, some people actually still program in Tcl. Some
of those programs are meant for interfacing with Git. Programs such as
gitk and git-gui. It may be useful to have Tcl-safe output available
from for-each-ref, just like shell, Perl and Python already enjoy.
Thanks to Sergey Vlasov for pointing out the horrible flaws in the
first and second version of this patch, and steering me in the right
direction for Tcl value quoting.

* maint:
revision traversal: --unpacked does not limit commit list anymore.
Continue traversal when rev-list --unpacked finds a packed commit.
Use memmove instead of memcpy for overlapping areas
quote.c: ensure the same quoting across platforms.
Surround "#define DEBUG 0" with "#ifndef DEBUG..#endif"
We read a byte from "char *" and compared it with ' ' to decide
if it needs quoting to protect textual output. With a platform
where char is unsigned char that would give different result.

Now if GIT_TRACE is set to an integer value greater than 1
and lower than 10, we interpret this as an open fd value
and we trace into it. Note that this behavior is not
compatible with the previous one.
We also trace whole messages using one write(2) call to
make sure messages from processes do net get mixed up in
the middle.
It's now possible to run the tests like this:
GIT_TRACE=9 make test 9>/var/tmp/trace.log

Though very nice and readable, the "case 'a'...'z':" construct is not ANSI C99
compliant. This patch unfolds the range in `quote.c' and substitutes the
switch-statement with an if-statement in `http-fetch.c' and `http-push.c'.

The switch is inside an if statement which is false if
the character is ' '. Either the if should be <=' '
instead of <' ', or the case should be removed as it could
be misleading.

This adds a very git specific restricted shell, that can be
added to /etc/shells and set to the pw_shell in the /etc/passwd
file, to give users ability to push into repositories over ssh
without giving them full interactive shell acount.

Follow the "encode minimally" principle -- our tools, including
git-apply and git-status, can handle pathnames with embedded SP just
fine. The only problematic ones are TAB and LF, and we need to quote
the metacharacters introduced for quoting.

Following the list discussion, define two functions, quote_c_style and
unquote_c_style, to help adopting the proposed way for quoting funny
pathname letters for GNU patch. The rule is described in:
http://marc.theaimsgroup.com/?l=git&m=112927316408690&w=2
Currently we do not support the leading '!', but we probably should
barf upon seeing it. Rule B4. is interpreted to require always 3
octal digits in \XYZ notation.
