various: general adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.

Create a new MP branch for `multilink protocol'. Do lots of initial shuffling and grouping. Submitted by: Eivind Eklund <perhaps@yes.no>

struct physical;
o Move alias function pointers into loadalias.c o Move Var*Version into command.c o Remove struct pppVars (and there was much rejoicing) ! o Forward-decl some structs in .h files to avoid include ordering requirements and remove a few more redundant #includes.

struct bundle;
Decouple pap & chap output routines from the corresponding input routines and take advantage of the new init/continue interface in libradius. This allows a timely response on other links in an MP setup while RADIUS requests are in progress as well as the ability to handle other data from the peer in parallel. It should also make the future addition of PAM support trivial. While I'm in there, validate pap & chap header IDs if ``idcheck'' is enabled (the default) for other FSM packet types. NOTE: This involved integrating the generation of chap challenges and the validation of chap responses (and commenting what's going on in those routines). I currently have no way of testing ppps ability to respond to M$Chap CHALLENGEs correctly, so if someone could do the honours, it'd be much appreciated (it *looks* ok!).

o Move default MRU, MTU, ACCMAP and OPENMODE config values into struct lcp and display them in `show lcp'. o Remove `show mru' and `show mtu' and make the data part of `show lcp'. Also merge `set m[tr]u' and `set openmode' implementations into the SetVariable function. o `set timeout' only accepts the idle timer value as an argument. o Move our lqr period into struct lcp, and create a `set lqrperiod' command. Display it in `show lcp'. o Remove VarRetryTimeout, and implement it at the LCP, PAP, CHAP, CCP and IPCP levels, creating individual `set XXXretry' commands for each. They must be separate because they have different context requirements in multilink mode. o Display default config values in `show ccp'. o Tart the man page up a bit (wrt PPP/TCP, compression and LQR) and explain the new commands.

struct {
Allow control over the number of ConfigREQ & TermREQ attempts that are made in each of the FSMs (LCP, CCP & IPCP) and the number of REQs/Challenges for PAP/CHAP by accepting more arguments in the ``set {c,ip,l}cpretry'' and ``set {ch,p}apretry'' commands. Change the non-convergence thresholds to 3 times the number of configured REQ tries (rather than the previous fixed ``10''). We now notice repeated NAKs and REJs rather than just REQs. Don't suggest that CHAP 0x05 isn't supported when it's not configured. Fix some bugs that expose themselves with smaller numbers of retries: o Handle instantaneous disconnects (set device /dev/null) correctly by stopping all fsm timers in fsm2initial. o Don't forget to uu_unlock() devices that are files but are not ttys (set device /dev/zero). Fix a *HORRENDOUS* bug in RFC1661 (already fixed for an Open event in state ``Closed''): According to the state transition table, a RCR+ or RCR- received in the ``Stopped'' state are supposed to InitRestartCounter, SendConfigReq and SendConfig{Ack,Nak}. However, in ``Stopped'', we haven't yet done a TLS (or the last thing we did is a TLF). We must therefore do the TLS at this point ! This was never noticed before because LCP and CCP used not use LayerStart() for anything interesting, and IPCP tends to go into Stopped then get a Down because of an LCP RTR rather than getting a RCR again.
