MFC r274364:

Add baud rate support to telnet(1)

This implements part of RFC-2217

It's based off a patch originally written by Sujal Patel at Isilon, and
contributions from other Isilon employees.

telnet: Fix infinite loop if local output generates SIGPIPE.

Instead of catching SIGPIPE and jumping out of the signal handler with
longjmp, ignore it and handle write errors to the local output by exiting
from there. I have changed the error message to mention the local output
instead of NetBSD's wrong "Connection closed by foreign host". Write errors
to the network were already handled by exiting immediately and this now
applies to EPIPE too.

The code assumed that SIGPIPE could only be generated by the network
connection; if it was generated by the local output, it would longjmp out of
the signal handler and write an error message which caused another SIGPIPE.

Use __FBSDID vs. rcsid[]. Also protect sccs[] and copyright[] from GCC 3.3.

From the requestor:

"Could you do me a favor and fix sys_bsd.c to get the howmany() macro
from <sys/param.h>, instead of <sys/types.h>? This will save me from
having to worry about the unsync'd bits before making the change."

unbreak build:

commands.c, sys_bsd.c: comment out/remove junk after #endif/#else
network.c, terminal.c, utlities.c: include stdlib.h for exit(3)

Don't assume that the number of fds to select on is known quantity (in
this case 16). Use dynamic FD_SETs and calculated high-water marks
throughout. There are also too many versions of telnet in the tree.

Very large style makeover.

1) ANSIfy.
2) Clean up ifdefs so that
a) ones that never/always apply are appropriately either
fully removed, or just the #if junk is removed.
b) change #if defined(FOO) for appropiate values of FOO.
(currently AUTHENTICATION and ENCRYPTION)
3) WARNS=2 fixing
4) GC other unused stuff

This code can now be unifdef(1)ed to make non-crypto telnet.

Manually unifdef(1) CRAY, UNICOS, hpux and sun uselsess code.

Code merge and diff reduce with "base" telnet. This is the "later"
telnet, so it was treated as the reference code, except where later
commits were made to "base" telnet.

Reactivate SRA.

Make handling of SIGINT and SIGQUIT follow SIGTSTP in TerminalNewMode().
This allows people to break out of SRA authentication if they wish to.

Add missing $FreeBSD$ to files that are NOT still on vendor a branch.

Bring the FreeBSD changes to the virgin sources.

This commit was generated by cvs2svn to compensate for changes in r29088,
which included commits to RCS files with non-trunk default branches.

Initial import of BSD telnet. This will be used to build the kerberised
telnet, and after userland diffs have been merged in, will be used to
build the non-kerberised sources as well. (See unifdef(1) for details)
