* dll_init.cc (dll_dllcrt0): Don't try to initialize dll data if we're 

dynamically loaded since fork() doesn't work in that scenario anyway.
(dll_dllcrt0_1): Don't accommodate dynamically loaded dlls.
* exceptions.cc (ctrl_c_handler): Don't lock the process; there's too much risk
of deadlock.
* sigproc.cc (_cygtls::remove_wq): Don't try to remove anything from the waitq
if there is obviously nothing there.
* strace.cc (strace::activate): Allow stracing dynamically loaded cygwin1.dll.
