Christopher Faylor 9a4d574b8d Eliminate use of sigframe and sigthread throughout.
* Makefile.in (DLL_OFILES): Add sigfe.o.  Remove reliance on cygwin.def from
cygwin0.dll dependency since dependence on sigfe.o implies that.  Generate def
file on the fly using 'gendef'.
* configure.in: Don't auto-generate cygwin.def.
* configure: Regenerate.
* cygwin.din: Add SIGFE stuff where appropriate.
* dcrt0.cc (dll_crt0_1): Initialize cygwin tls early in process startup.  Set
_main_tls to address of the main thread's cygwin tls.
* debug.h: Remove now unneeded WFSO and WFMO declarations.
* exceptions.cc (_last_thread): Define.
(set_thread_state_for_signals): New function.
(reset_thread_exception_for_signals): Ditto.
(init_thread_for_signals): Ditto.

calling sig_send.

* init.cc (dll_entry): Initialize cygwin tls storage here.
* miscfuncs.cc (low_priority_sleep): Make a C function for easier calling from
asm.
* perthread.h (vfork_save::tls): New element.

* cygtls.h: New file.
* gendef: New file.
* gentls_offsets: New file.
