* cygtls.h (_threadinfo::stack): Increase stack size to accommodate nested

signal handlers.  Reorganize to cause potential SEGV on stack overflow.
* sigproc.cc (no_signals_available): Check sendsig value rather than relying on
obsolete sig_loop_wait.
(sigproc_terminate): Ditto.
(proc_can_be_signalled): Check sendsig value even for myself.
* tlsoffsets.h: Regenerate.
