mail/dovecot, mail/dovecot-pigeonhole: upgrade to 2.3.6, 0.5.6 respectively.

Dovecot changelog:
* CVE-2019-11494: Submission-login crashed with signal 11 due to null pointer
access when authentication was aborted by disconnecting.
* CVE-2019-11499: Submission-login crashed when authentication was started over
TLS secured channel and invalid authentication message was sent.
* auth: Support password grant with passdb oauth2.
+ Use system default CAs for outbound TLS connections.
+ Simplify array handling with new helper macros.
+ fts_solr: Enable configuring batch_size and soft_commit features.
- lmtp/submission: Fixed various bugs in XCLIENT handling, including a hang when
XCLIENT commands were sent infinitely to the remote server.
- lmtp/submission: Forwarded multi-line replies were erroneously sent as two
replies to the client.
- lib-smtp: client: Message was not guaranteed to contain CRLF consistently when
CHUNKING was used.
- fts_solr: Plugin was no longer compatible with Solr 7.
- Make it possible to disable certificate checking without setting
ssl_client_ca_* settings.
- pop3c: SSL support was broken.
- mysql: Closing connection twice lead to crash on some systems.
- auth: Multiple oauth2 passdbs crashed auth process on deinit.
- HTTP client connection errors infrequently triggered a segmentation fault when
the connection was idle and not used for a particular client instance.

Pigeonhole changelog:
+ sieve: Redirect loop prevention is sometimes ineffective. Improve existing
loop detection by also recognizing the
  X-Sieve-Redirected-From header in incoming messages and dropping redirect
actions when it points to
  the sending account. This header is already added by the redirect action, so
this improvement only adds an additional use of this header.
- sieve: Prevent execution of implicit keep upon temporary failure occurring at
runtime.
