Log Message:
Update "rp-pppoe" package to version 3.5. Changes since version 3.3:
- Fixes for compilation on Solaris.
- INCOMPATIBILITY WITH EARLIER VERSIONS:
  Kernel-mode plugin now is built against latest CVS ppp source rather than
  Michal Ostrowski's patched version.  If you use kernel-mode PPPoE, you
  MUST use the CVS version of the ppp source code with rp-pppoe 3.4.
- Print PPPoE session number when connection terminates.  Thanks to
  Alexander Dalloz for suggesting this.
- Fixed a bug in MSS clamping -- it now works with protocol-field compression.
  Thanks to Gerd v. Egidy for the patch.
- Ignore SIGINT and SIGTERM so LCP termination packets make it out.

This update also contains a patch for PR pkg/18525 by Lex Wennmacher.
