path_name is either ptr that should not be freed, or a pointer to a strbuf
buffer that is deallocated when exiting the loop. Don't do that !

The code incorrectly assumed that strbuf.buf is always an
allocated piece of memory that has NUL at offset strbuf.len.
That assumption does not hold for a freshly initialized empty
strbuf.

This function cannot fail, make it void. Also make write_one act on a
const char* instead of a char*.

strbuf_setlen() expect to be able to NUL terminate the buffer,
but a completely empty strbuf could have an empty buffer with 0
allocation; both the assert() and the assignment for NUL
termination would fail.

* sq_quote_buf is made public, and works on a strbuf.
* sq_quote_argv also works on a strbuf.
* make sq_quote_argv take a "maxlen" argument to check the buffer won't grow
too big.

* quote_c_style works on a strbuf instead of a wild buffer.
* quote_c_style is now clever enough to not add double quotes if not needed.
* write_name_quoted inherits those advantages, but also take a different
set of arguments. Now instead of asking for quotes or not, you pass a
"terminator". If it's \0 then we assume you don't want to escape, else C
escaping is performed. In any case, the terminator is also appended to the
stream. It also no longer takes the prefix/prefix_len arguments, as it's
seldomly used, and makes some optimizations harder.
* write_name_quotedpfx is created to work like write_name_quoted and take
the prefix/prefix_len arguments.
Thanks to those API changes, diff.c has somehow lost weight, thanks to the
removal of functions that were wrappers around the old write_name_quoted
trying to give it a semantics like the new one, but performing a lot of
allocations for this goal. Now we always write directly to the stream, no
intermediate allocation is performed.
As a side effect of the refactor in builtin-apply.c, the length of the bar
graphs in diffstats are not affected anymore by the fact that the path was
clipped.

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.

Add strbuf_remove, change strbuf_insert:
As both are special cases of strbuf_splice, implement them as such.
gcc is able to do the math and generate almost optimal code this way.
Add strbuf_swap:
Exchange the values of its arguments.
Use it in fast-import.c
Also fix spacing issues in strbuf.h

* drop nfasprintf.
* move nfvasprintf into imap-send.c back, and let it work on a 8k buffer,
and die() in case of overflow. It should be enough for imap commands, if
someone cares about imap-send, he's welcomed to fix it properly.
* replace nfvasprintf use in merge-recursive with a copy of the strbuf_addf
logic, it's one place, we'll live with it.
To ease the change, output_buffer string list is replaced with a strbuf ;)
* rework trace.c to call vsnprintf itself. It's used to format strerror()s
and git command names, it should never be more than a few octets long, let
it work on a 8k static buffer with vsnprintf or die loudly.

The example provided with the update-hook-example does not work on
either bash 2.05b.0(1)-release nor 3.1.17(1)-release. The matcher did
not match the lines that it advertised to match, such as:
refs/heads/bw/ linus
refs/heads/tmp/* *
In POSIX 1003.2 regular expressions, the star (*), is not an wildcard
meaning "match everything", it matches 0 or more matches of the atom
preceding it.
So to match "refs/heads/bw/topic-branch", the matcher should be written
as "refs/heads/bw/.*" to match "refs/heads/bw/" and everything after it.

Earlier commit ece7b74903007cee8d280573647243d46a6f3a95 added a test
for rebase that uses "am -3", but this adds a test to check "am -3"
itself.

This moves "shift" out of the argument processing "case". It also
replaces quite a bit of expr calls with ${parameter#word} constructs,
and uses ${parameter:+word} for avoiding conditionals where possible.
