Update sysutils/rsyslog to 8.10.0.

Version 8.10.0 [v8-stable] 2015-05-19
- imfile: add capability to process multi-line messages based on regex
  input parameter "endmsg.regex" was added for that purpose. The new
  mode provides much more power in processing different multiline-formats.
- pmrfc3164: add new parameters
  * "detect.yearAfterTimestamp"
    This supports timestamps as generated e.g. by some Aruba Networks
    equipment.
  * "permit.squareBracesInHostname"
    Permits to use "hostnames" in the form of "[127.0.0.1]"; \ 
also seen in
    Aruba Networks equipment, but we strongly assume this can also happen
    in other cases, especially with IPv6.
- supplementary groups are now set when dropping privileges
  closes https://github.com/rsyslog/rsyslog/issues/296
  Thanks to Zach Lisinski for the patch.
- imfile: added brace glob expansion to wildcard
  Thanks to Zach Lisinski for the patch.
- zmq: add the ability for zeromq input and outputs to advertise their
  presence on UDP via the zbeacon API.
  Thanks to Brian Knox for the contribution.
- added omhttpfs: contributed module for writing to HDFS via HTTP
  Thanks to sskaje for the contribution.
- Configure option "--disable-debug-symbols" added which is disabled per
  default. If you set the new option, configure won't set the appropriate
  compiler flag to generate debug symbols anymore.
- When building from git source we now require rst2man and yacc (or a
  replacement like bison).
  That isn't any new requirement, we only added missing configure checks.
- Configure option "--enable-generate-man-pages" is now disabled for \ 
non git
  source builds per default but enforced when building from git source.
- mmpstrucdata: some code cleanup
  removed lots of early development debug outputs
- bugfix imuxsock: fix a crash when setting a hostname
  Setting a hostname via the legacy directive would lead to a crash
  during shutdown caused by a double-free.
  Thanks to Tomas Heinrich for the patch.
- bugfix: memory leak in mmpstrucdata
  Thanks to Gregoire Seux for reporting this issue.
  closes https://github.com/rsyslog/rsyslog/issues/310
- bugfix (minor): default action name: assigned number was one off
  see also https://github.com/rsyslog/rsyslog/pull/340
  Thanks to Tomas Heinrich for the patch.
- bugfix: memory leak in imfile
  A small leak happened each time a new file was monitored based on
  a wildcard. Depending on the rate of file creation, this could result
  in a serious memory leak.
