Use new (inline) functions for calls into driver.

- Use ng_callout() instead of home-grown implementation.

Fix broken ng_h4(4). Basically, do not abuse t_sc field and use new t_lsc
field created for line disciplne drivers private use. Also add NET_NEEDS_GIANT
warning. For whatever reason ng_tty(4) was fixed but ng_h4(4) was not :(

Fix line discipline switching issues: If opening a new ldisc fails,
we have to revert to TTYDISC which we know will successfully open
rather than try the previous ldisc which might also fail to open.

Do not let ldisc implementations muck about with ->t_line, and remove
code which checks for reopens, it should never happen.

Move ldisc->l_hotchar to tty->t_hotchar and have ldisc implementation
initialize it in their open routines. Reset to zero when we enter
TTYDISC. ("no" should really be -1 since zero could be a valid
hotchar for certain old european mainframe protocols.)

Do the dreaded s/dev_t/struct cdev */
Bump __FreeBSD_version accordingly.

Change to C99 structure initialisation for the type method structure.

Address few style issues pointed out by bde

Replace deprecated NG_NODELEN with the new NG_NODESIZ. There is one
problem here still to be solved: the sockaddr_hci has still a 16 byte
field for the node name. The code currently does not correctly use the
length field in the sockaddr to handle the address length, so
node names get truncated to 15 characters when put into a sockaddr_hci.

Has been seen to work on several cards and communicating with
several mobile phones to use them as modems etc.

We are still talking with 3com to try get them to allow us to include
the firmware for their pccard in the driver but the driver is here..
In the mean time
it can be downloaded from the 3com website and loaded using the utility
