From: Christopher Faylor <me@cgf.cx>

Subject: * fhandler.cc (fhandler_base::fork_fixup): Don't protect handle. *
 dlfcn.cc: Fix to confirm to coding standards.  Reorganize includes throughout
 to accomodate new cygheap.h usage. * cygheap.h (cygheap_fdmanip): New class:
 simplifies locking and retrieval of fds from cygheap->fdtab. (cygheap_fdget):
 Ditto. (cygheap_fdnew): Ditto. * fcntl.cc (_fcntl): Use new method to lock
 fdtab and retrieve info. * ioctl.cc (ioctl): Ditto. * mmap.cc (mmap): Ditto.
 * net.cc: Ditto, throughout. * passwd.cc (getpass): Ditto. * path.cc
 (fchdir): Ditto. * pipe.cc (make_pipe): Ditto. * sec_acl.cc (facl): Ditto. *
 syscalls.cc: Ditto, throughout. * termios.cc: Ditto, throughout.
