* cygheap.cc (cygheap_fixup_in_child): Don't close parent handle here. Let the

Browse Source 
caller do that.
* dcrt0.cc (child_info_spawn::handle_spawn): Close parent handle here to allow
fixup_after_exec functions to use it.
* cygtls.cc (_cygtls::call2): Avoid calling exit thread if called with
*crt0_1 functions.
* cygtls.h (_cygtls::isinitialized): Check that we actually have a tls before
seeing if it is initialized.
* gendef (_sigfe_maybe): Ditto.
* dcrt0.cc (dll_crt0_1): Remove static, use just one argument.
* dll_init.cc (dllcrt0_info): New structure.
(dll_dllcrt0): Change into a front-end to renamed dll_dllcrt0_1 so that we'll
always be assured of having something like a tls.
(dll_dllcrt0_1): New function, basically renamed from from dll_dllcrt0.
Unconditionally call _my_tls.init_exception_handler now that we are assured of
having a tls.  Change variable name from "linking" to "linked".
* winsup.h (dll_crt0_1): Declare.
(dll_dllcrt0_1): Ditto.
