update rfcomm_sppd to use the new Service Discovery API

does no longer need libsdp

Ensure that these programs continue to build while I am in the
process of updating the Service Discovery Protocol API.

branches: 1.2.20;
Add new Makefile knob, USE_FORT, which extends USE_SSP by turning on the
FORTIFY_SOURCE feature of libssp, thus checking the size of arguments to
various string and memory copy and set functions (as well as a few system
calls and other miscellany) where known at function entry. RedHat has
evidently built all "core system packages" with this option for some time.

This option should be used at the top of Makefiles (or Makefile.inc where
this is used for subdirectories) but after any setting of LIB.

This is only useful for userland code, and cannot be used in libc or in
any code which includes the libc internals, because it overrides certain
libc functions with macros. Some effort has been made to make USE_FORT=yes
work correctly for a full-system build by having the bsd.sys.mk logic
disable the feature where it should not be used (libc, libssp iteself,
the kernel) but no attempt has been made to build the entire system with
USE_FORT and doing so will doubtless expose numerous bugs and misfeatures.

Adjust the system build so that all programs and libraries that are setuid,
directly handle network data (including serial comm data), perform
authentication, or appear likely to have (or have a history of having)
data-driven bugs (e.g. file(1)) are built with USE_FORT=yes by default,
with the exception of libc, which cannot use USE_FORT and thus uses
only USE_SSP by default. Tested on i386 with no ill results; USE_FORT=no
per-directory or in a system build will disable if desired.

fix offset/indent of list

Merge riastradh-drm2 to HEAD.

Use Mt for email addresses.

Sort sections.

In server mode, relax the requirement to specify a channel number. If
one is not given, attempt to allocate the first unused one.

-s can be used in server mode too

Add a new feature, allow to specify an alternative PSM value for the
RFCOMM protocol to use in client or server mode. Also, handle the case
where service search of the remote device returns non-standard PSM.

Drop trailing whitespace. Fix typo and casing.

branches: 1.5.4;
Add 'service level' security for L2CAP and RFCOMM connections, following
the Linux (BlueZ) API.

- L2CAP or RFCOMM connections can require the baseband radio link
mode be any of:
authenticated (devices are paired)
encrypted (implies authentication)
secured (encryption, plus generate new link key)

- for sockets, the mode is set using setsockopt(2) and the socket
connection will be aborted if the mode change fails.

- mode settings will be applied during connection establishment, and
for safety, we enter a wait state and will only proceed when the mode
settings are successfuly set.

- It is possible to change the mode on already open connections, but
not possible to guarantee that data already queued (from either end)
will not be delivered. (this is a feature, not a bug)

- bthidev(4) and rfcomm_sppd(1) support "auth", "encrypt" and
"secure" options

- btdevctl(8) by default enables "auth" for HIDs, and "encrypt" for
keyboards (which are required to support it)

rework the -c and -s options to make them a bit more consistent.

when EOF is reached, we are done.

Sort sections. New sentence, new line.

This comprises a rewrite, which
- adds a server mode for incoming bluetooth connections
- does not cfmakeraw the slave tty as this caused problems
- does not hold open the slave tty as this prevented multiple opens
- modifies the termios for stdio so that this can be used directly
by a user.

only modify the termios structure when tty_in is verifiably a terminal
