A goal is to eventually fully replace use of KWSys Process with libuv.
I'd prefer not to make any major changes to KWSys Process in the meantime.

Currently libuv is used only for the server mode, but soon it will be
used for CTest too:

Use of libuv's process management for that would be good.  It supports
fully asynchronous operation and so can manage many child processes from
one thread.
