Subject: * exceptions.cc (unused_sig_wrapper): Eliminate unused parameter to
 asm. * external.cc (cygwin_internal): Change CW_STRACE_ON to
 CW_STRACE_TOGGLE. * strace.cc (strace::hello): Toggle strace on and off. *
 sync.cc (muto::init): Renamed from constructor. * sync.h (muto::new): Delete.
 (muto::delete): Ditto. (new_muto): Simplify.  Use muto.init for nearly
 everything. * uinfo.cc (uinfo_init): Avoid closing a NULL handle. *
 include/sys/cygwin.h (cygwin_getinfo_types): Rename CW_STRACE_OFF to
 CW_STRACE_TOGGLE.  Delete CW_STRACE_OFF. * include/sys/strace.h (strace): Add
 "inited" field.
