required to allow use of some things from user loaded DLL.
(CW_STRACE_ON): Add new feature.
(CW_CYGWIN_PID_TO_WINPID): Ditto.
* pinfo.cc (set_myself): Call "strace.hello" to initiate possible strace
session.
(pinfo::init): Guard against dereferencing uninitialized myself.
* sigproc.cc (wait_sig): Call strace.hello() when __SIGTRACE "signal" received.
* strace.cc (strace::hello): New method.
* wincap.cc (wincapc::init): Avoid initializing if already initialized.
* wincap.h (wincapc::wincapc): New method.
* include/sys/cygwin.h: Add new CW_ enums. Kludge typedefs of {g,u}id_t if
required.
* strace.h (strace::hello): Declare new method.
