Deleting llc_actn.[ch], llc_evnt.[ch] & llc_stat.[ch], now it is
clearly separated from the rest and lots of previously externally
visible thru headers stuff is nicely restrained in this file.

Also remove the silly passing around of pointers to llc_main_station,
use it directly.

First step at coalescing the station handling into just one file,
killing some useless headers in the process.

Renaming the basic support module to llc.ko and introducing llc_core.c,
that has just the basic output path for llc_build_and_send_ui_pkt.

Next step will be to rename llc_main.c to llc_station.c, then consolidate
all the llc station code in this file, removing all the not needed
llc_station parameters and killing struct llc_station altogether,
no sense in having it as there is just one station, always. BTW in
this changeset parts of llc_main_station was already moved to llc_core.c,
namely the sap list and lock.

Next step: to have llc_build_and_send_ui_pkt in llc_output.c, not
using the silly sap state machinery.

Renaming lan_hdrs_init to llc_mac_hdr_init and making all places
check if it fails.

Also rename fix_up_incoming_skb to llc_fixup_skb, to be more
namespace friendly. Ah, make it inline too.

For this some more functions had to be moved around, now one doesn't
have to explicitely select LLC to have access in the menu to ipx,
appletalk, token ring, etc.

This is not yet as good as I want it to be, but at least makes it
easier for the hordes of users to select stuff, making it look more
like how it was in 2.4.

In the next changesets I'll fix the fact that CONFIG_TR is a bool
and makes psnap, p8022 and llc_core to be built statically even tho
the token ring drivers are being build as modules.

Making them inline, as they are small enough and some very seldomly
used.

Also move llc_save_primitive to llc_sap, almost untangling the
LLC2 stack from the core.

Also add a prototype for llc_conn_rcv, that will move away in
the next changesets. but for now is needed to kill a warning.

And also rename it to llc_pdu_type and make it return the type,
this is to make llc_mac more and more autonomous of the rest of
the llc code, to the point where it will be a separate loadable
module.

This is the start of the split of LLC into a core part and the
bigger, not needed by ipx, token ring, appletalk, etc, LLC2 stack.

This will allow fixing races with rmmod and sysfs access.

Harald synced up ipt_REJECT.c from 2.4 route fixes, but it had
changed a fair bit because of the nonlinear fixes.  This repairs it.

1) Copying of tcp header onto stack.
2) ...which also checks length requirement.
3) Skip checksum check: requires linear packet.

Herve Eychenne noted that many ADSL connections get the same
address when the interface comes back up, so some users use SNAT
instead of masquerade.  The answer is that MASQUERADE should only
drop connections when the interface comes up, and then only if the
interface address has actually changed.
