be used by subsequent startup functions.
(dll_crt0_0): Issue a warning if DuplicateTokenEx fails and DEBUGGING.
(dll_crt0_1): Move user_data->{resourcelocks,threadinterface} initialization
here from dll_crt0_0.
* fork.cc (frok::child): Tell wait_for_sigthread that this is fork.
(frok::parent): Only initialize start_time once.  Tighten time when we're
"deimpersonated".
* sigproc.cc (signal_fixup_after_exec): Rework (futiley) sa_buf stuff.  Add
debugging output.
(wait_for_sigthread): Accept an argument which illustrates whether we are
forked or not.
(wait_sig): Avoid using myself pointer.
* winsup.h ((wait_for_sigthread): Reflect change to argument.
