* dll_init.h (class dll_list): Reorder functions to avoid compiler "can't

inline" warnings.
* security.h (class cygsid): Ditto.
* sigproc.cc (get_proc_lock): Ditto.
* sigproc.h (class sigframe): Ditto.
* sync.h (class muto): Ditto.
* fhandler.h (fhandler_base::get_guard): Actually MAKE virtual as previously
indicated.
* pipe.cc (make_pipe): Remove extraneous set_errno.
* syscalls.cc (_open): Ditto.
* select.cc (peek_pipe): Need to check that there is still something to read
from the pipe after acquiring the mutex since another process/thread could have
eaten the input before we got to acquiring the lock.  (Thanks to Nick Duffek
for this inspiration.)
