Rework unquote_c_style to work on a strbuf.
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. Signed-off-by: Pierre Habouzit <madcoder@debian.org>
