fixing two smaller nits noticed by Ramsay
* make struct parallel_processes static
* omit the forward declaration of get_next_submodule by reordering.
Jonathan Nieder (1):
submodule.c: write "Fetching submodule <foo>" to stderr
Stefan Beller (7):
xread: poll on non blocking fds
xread_nonblock: add functionality to read from fds without blocking
strbuf: add strbuf_read_once to read without blocking
sigchain: add command to pop all common signals
run-command: add an asynchronous parallel child processor
fetch_populated_submodules: use new parallel job processing
submodules: allow parallel fetching, add tests and documentation
