* cygwin-gperf: New file.

* Makefile.in: Use cygwin-gperf script to build devices.cc.
* configure.in: Remove some comments.
* configure: Regenerate.
* devices.gperf: Remove max unit determination from FH_TTY.  Add /dev/kmem.
Add /dev/fifo.  Add /dev/rawdrive.  Remove specific "const device *"
declarations since they are now autogenerated.
(device::parse): Treat FH_TTY specially.  Move logic for determining real tty
device to separate function.
(device::init): Reduce to nothing.
(device::parse): New function taking different arguments.
(device::parse): Ditto.
(device::tty_to_real_device): New function.
* devices.h (struct device): Define above new functions.
(device::dev_on_fs): New element.
(device::setfs): New function.
(device::isfs): Ditto.
* dtable.cc (dtable::build_fhandler): Treat FH_TTY specially.
* fhandler.cc (fhandler_base::set_name): Make special determination for
non-disk-resident devices.
* fhandler.h (fhandler_base::isdevice): Renamed from 'is_device'.
(fhandler_disk_file::isdevice): Ditto.
(fhandler_base::is_auto_device): New function.
(fhandler_base::is_fs_device): New function.
(fhandler_tty_slave::get_unit): Declare.
(fhandler_disk_file::readdir): Take special .lnk consideration for devices as
well as symlinks.
* fhandler_tty.cc: Use get_unit () rather than dev.minor throughout.
(fhandler_tty_slave::get_unit): Define new function.
* path.cc (symlink_info::major): New element.
(symlink_info::major): Ditto.
(symlink_info::devtype): Ditto.
(path_conv::check): Handle devices detected by symlink_info::check.
(win32_device_name): Eliminate special FH_TTY handling.
(symlink): Move bulk of procesing to symlink_worker.
(symlink_worker): New function.  Handles devices.
(symlink_info::parse_device): Parse info from potential device file into
symlink_info elements.
(symlink_info::check): If contents of .lnk file begin with a ':' then treat the
file as a device file.
* path.h (isdevice): Renamed from is_device.
(is_auto_device): New function.
(is_fs_device): Ditto.
* syscalls.cc (chown_worker): Allow setting of ownership for on-disk devices.
(chmod): Ditto.
(mknod): Implement.
* winsup.h (symlink_worker): Declare.
