3.7.0alpha2

This is the second alpha release of the syslog-ng OSE 3.7
branch.

Changes compared to the previous alpha release:

Features

• Added support for the monolithic libsystemd library (systemd 209).
• New parameter added to loggen: --permanent (-T) wich is for sending logs
  indefinitely.
• Earlier, in patterndb, the first applicable rule won, even if it was
  only a partial match. This means that when rules overlapped, the shorter
  match would have been found, if it was the first to be loaded.
  A strong preference introduced for rules that match the input string
  completely. The load order is still applicable though, it is possible to
  create two distinct rules that would match the same input, in those cases
  the first one to be loaded wins.
• New parser, extract-solaris-msgid() added for automatically extracts
  (parses & removes) the msgid portion of Solaris messages.

Fixes

• In some cases program destination respawned during syslog-ng stop/restart.
• Max packet length for spoof source is set to 1024 (previously : 256).
• Removed syslog.socket from service file on systems using systemd.
  Syslog-ng reads the messages directly from journal on systems with systemd.
• In some cases, localtime related macros had a wrong value(eg.:$YEAR).
• Transaction handling fixed in SQL destination. In some circumstances when
  both select and insert commands were run within a single transaction and
  the select failed (eg.: in case of mssql), the log messages related to
  the insert commands, broken by the invalid transaction, were lost.
• Fixed a memleak in SQL destination driver.
  The memleak occured during one of the transaction failures.
• A certificate which is not contained by the list of fingerprints is
  rejected from now.
• Hostname check in tls certificate is case insensitive from now.
• Fix spinning on EOF for unix-stream() sockets. Root cause of the spinning
  was that a unix-dgram() socket was created even in case of unix-stream().
• There is a use-case where user wants to ignore an assignment to a name-value
  pair. (eg.: when using csv-parser(), sometimes we get a column we really
  want to drop instead of adding it to the message). In previous versions an
  error message was printed out:
  'Name-value pairs cannot have a zero-length name'.
  That error message has been removed.
• pdbtool match when used with the --debug-pattern option used a low-level
  lookup function, that didn't perform all the db-parser actions specified
  in the rule

Developer notes

• PatternDB lookup refactored (it is easier to understand the code).
