  Move config to a backend structure Configuration options can come from different sources. Currently, there is only support for reading them from a flat file, but it might make sense to read it from a database at some point. Move the parsing code into src/config_file.c and create an include file include/git2/config_backend.h to allow for other backends to be developed. Signed-off-by: Carlos Martín Nieto <cmn@elego.de>
