[GSoC][PATCH v8 00/20] Convert "git stash" to C builtin

Hello,

This a new iteration of `stash.c`. What is new?

 * Some commits got squashed. The commit related to replacing
 `git apply` child process was dropped since it wasn't the best
 idea.

 * In v7, there was a bug [1] related to config `git stash show`
 The bug was fixed and a test file was added for this.

 * Fixed `git stash [push]` [2]. In v7, `git stash -q drop` would
 act like `git stash push -q drop`.

 * Fixed coding-style nits. Verified that messages are marked
 for translation and are going to the correct output stream.

 * Fixed one memory leak (related to `strbuf_detach`).

 * Simplified the code a little bit.
