* cygthread.h (cygthread::name): Default name to "main" if we are early in the

process of setting up the DLL and no name is known.
* dcrt0.cc (initial_env): Remove CYGWIN_SLEEP stuff.
(get_cygwin_startup_info): Activate strace here as appropriate.
(dll_crt0_0): Move get_cygwin_startup_info as early as possible to avoid
missing strace output.
* fork.cc (frok::child): Move debugging statement to point where ppid will be
set.
* pinfo.cc (pinfo::thisproc): Remove obsolete call to strace.hello.  Tweak
debug output slightly.
* select.cc (select_stuff::wait): Allow APCS to be triggered while waiting
since we use them now.  Report when that happens.
* sigproc.cc (child_info::child_info): Use strace.active() rather than
strace.attached().
* spawn.cc (child_info_spawn::worker): Only write strace child pid when we know
it's a cygwin process.  Accommodate change to write_child argument list.
* strace.cc (strace::hello): Delete.  Move functionality...
(strace::activate): ...to here.
(mypid): Just use raw GetCurrentProcessId () if myself isn't set.
(strace::write_childpid): Don't wait for subproc_ready.  Remove arg which was
required for it.
* include/sys/strace.h (strace::hello): Delete.
(strace::write_childpid): Delete first argument.
