Andrew Gallatin 2c4ab9ddfa Make linux_sendsig and linux_sigreturn use all 64 bits of a
linux_sigset_t by updating the linux_sigframe struct so as to include
linux's "extramask" field.  This field contains the upper 32-bits of
the sigset.  extramask sits behind a linux_fpstate struct, which I've
defined primarily for padding purposes.

While we're here, define LINUX_NSIG in terms of LINUX_NBPW (32) and
LINUX_NSIG_WORDS (2).

This fixes problems where threaded apps would accumulate a large
number of zombies.  This was happening because the exit signal resides
in the upper 32-bits of the sigset and was never getting unmasked by
the manager thread after the first child exited.
