New release 1.3.8

[Ondrej Filip]

Hi Bird users,
Santiago did a great job and we have new version 1.3.8. This release
includes many improvements. BGP filters can propagate the best
secondary route if the primary is rejected. This feature can simplify
design of BGP route servers and can save a lot of memory. I will post
some examples to wiki soon.


Version 1.3.8 (2012-08-07)
  o Generalized import and export route limits.
  o RDNSS and DNSSL support for RAdv.
  o Include in config file support wildcards.
  o History deduplication in BIRD client.
  o New route attributes krt_source, krt_metric.
  o Different instance ID support for OSPFv3.
  o Real broadcast mode for OSPFv2.
  o Several minor bugfixes.
