Misc fixes for sl(4) and slattach(8) man pages:
- note that ifconfig(8) create subcommand is required before slattach(8)
- network addresses aren't defined by slattach(8) but ifconfig(8)
- Add a BUGS section in slattach(8) to note that currently there is no way to
specify/see an interface name to be attached
- move description about link[0-2] flags from slattach(8) to sl(4)
(rather than adding a new description...)
- move description about SLIP limitations to a new BUGS section in sl(4)
- remove inappropriate MLINKS of slip.8 to slattach.8
- create MLINKS of slip.4 to sl.4 instead
- add some more xrefs

fix type, from Mark Weaver

deal with change in setting of slip params

From: Ian McDonnell <imcd@apriori.demon.co.uk>
* Initialize termios struct before using it, from the current tty settings.
* Set speed earlier. (This, combined with the above, was causing DTR to be
dropped briefly on startup.)
* Add `-m' option to avoid using HUPCL.
Also:
* Remove findspeed() altogether, as we don't need it and it's ugly.
* Use tcgetattr() and tcsetattr() rather than TIOCGETA and TIOCSETA. The
former is POSIX; the latter is not.

Add RCS indentifiers.

patched w/changes from blymn@mulga.awadi.com.AU (Brett Lymn) to
fix things like flow control support, SLIP option support etc.

changed "Id" to "Header" for rcsids

added rcs ids to all files
