Cygwin: Add C11 threads API

Code taken from FreeBSD, which implements C11 threads as
wrapper around pthreads.  Fix up machine/_threads.h which
is called from newlib's machine-independent threads.h to
match Cygwin's pthreads types.

Add the FreeBSD source files to libc subdir and take
opportunity to define LIBC_OFILES var in Makefile.

Add new symbols to common.din and sort symbols.
