[PATCH v11 00/22] Convert "git stash" to C builtin

Hello,

This is the 11th iteration of C git stash. Here are some of the changes, based on Thomas's and dscho's suggestions (from mailing list / pull request #495):

- improved memory management. Now, the callers of `do_create_stash()`
are responsible of freeing the parameter they pass in. Moreover, the
stash message is now a pointer to a buffer (in the previous iteration
it was a pointer to a string). This should make it more clear who is
responsible of freeing the memory.

- added `strbuf_insertf()` which inserts a format string at a given
position in the buffer.

- some minor changes (changed "!oidcmp" to "oideq")

- fixed merge conflicts

Best regards, Paul
