Brian Somers cd9647a100 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.
