* anders/diameter/dictionaries/OTP-11958:
  Fix broken check for undefined AVPs in @codec and @custom_types
  Add @codecs and @custom_types tests to compiler suite

Dictionary compilation fails to detect undefined AVPs in these sections.

* anders/diameter/Failed-AVP/OTP-11936:
  Do best-effort decode of Failed-AVP
  Add a testcase that expects a decoded value in Failed-AVP

* anders/diameter/5014/OTP-11946:
  Fix handling of AVP length errors (5014) in unknown AVPs
  Add testcases that send unknown AVPs with a bad AVP Length

This isn't currently the case, but soon will be.

In particular, a length that points past the end of the message. This
goes undetected there is some other problem with the AVP (eg. M-bit),
which is a problem we're about to fix.

* anders/diameter/sctp/OTP-11901:
  Fix diameter_sctp function_clause
  Anchor path regexps in examples suite
  Run examples suite over both TCP and SCTP

* anders/diameter/request_leak/OTP-11893:
  Fix leaking request table
  Add check that request table is empty to failover suite
  Comment fix

They match emacs backup files and more without the anchor, although this
doesn't stop the matches from finding files the suite isn't (yet)
intended to test: files under development, not yet commited, etc.

This was supposed to already be the case (in what passes for my memory),
and detects that commit ed6395a6 is horrifically broken: diameter is
unable to send CEA over SCTP.
