Version bump to 1.5.1

CHANGELOG.
+ BMP daemon: BMP, BGP Monitoring Protocol, can be used to monitor BGP
  sessions. The current implementation is base on the draft-ietf-grow-bmp-07
  IETF draft. The daemon currently supports BMP events and stats only, ie.
  initiation, termination, peer up, peer down and stats reports messages.
  Route Monitoring is future (upcoming) work but routes can be currently
  sourced via the BGP daemon thread (best path only or ADD-PATH), making
  the two daemons complementary. The daemon enables to write BMP messages
  to files or AMQP queues, real-time (msglog) or at regular time intervals
  (dump) and is a separate thread in the NetFlow (nfacctd) or sFlow (sfacctd)
  collectors.
+ tmp_net_own_field directive is introduced to record both individual source
  and destination IP addresses and their IP prefix (nets) as part of the same
  aggregation method. While this should become default behaviour, a knob for
  backward-compatibility is made available for all 1.5 until the next major
  release.
+ Introduced nfacctd_stitching and equivalents (ie. sfacctd_stitching):
  when set to true, given an aggregation method, two new non-key fields are
  added to the aggregate upon purging data to the backend: timestamp_min is
  the timestamp of the first element contributing to a certain aggregate
  and timestamp_max is the timestamp of the last element. In case the export
  protocol provides time references, ie. NetFlow/IPFIX, these are used; if not
  the current time (hence time of arrival to the collector) is used instead.
+ Introduced amqp_routing_key_rr feature to perform round-robin load-
  balancing over a set of routing keys. This is in addition to existing,
  and more involved, functionality of tag-based load-balancing.
+ Introduced amqp_multi_values feature: this is same feature in concept as
  sql_multi_values (see docs). The value is the amount of elements to pack
  in each JSON array.
+ Introduced amqp_vhost and companion (ie. bgp_daemon_msglog_amqp_vhost)
  configuration directives to define the AMQP/RabbitMQ server virtual host.
+ BGP daemon: bgp_daemon_id now allows to define the BGP Router-ID disjoint
  from the bgp_daemon_ip definition. Thanks to Bela Toros for his patch.
+ tee plugin: introduced tee_ipprec feature to color replicated packets,
  both in transparent and non-transparent modes. Useful, especially when
  in transparent mode and replicating to hosts in different subnets, to
  verify which packets are coming from the replicator.
+ tee plugin: plugin-kernel send buffer size is now configurable via a new
  config directive tee_pipe_size. Improved logging of send() failures.
+ nfacctd: introduced support for IPFIX sampling/renormalization using
  element IDs: #302 (selectorId), #305 (samplingPacketInterval) and #306
  (samplingPacketSpace). Many thanks to Rene Stoutjesdijk for his support.
+ nfacctd: added also support for VLAN ID for NetFlow v9/IPFIX via element
  type #243 (it was already supported via elements #58 and #59). Support was
  also added for 802.1p/CoS via element #244.
+ nfacctd: added native support for NetFlow v9/IPFIX IE #252 and #253 as
  part of existing primitives in_iface and out_iface (additional check).
+ pre_tag_map: introduced 'cvlan primitive. In NetFlow v9 and IPFIX this is
  compared against IE #245. The primitive also supports map indexing.
+ Introduced pre_tag_label_filter to filter on the 'label' primitive in a
  similar way how the existing pre_tag_filter feature works against the
  'tag' primitive. Null label values (ie. unlabelled data) can be matched
  using the 'null' keyword. Negations are allowed by pre-pending a minus
  sign to the label value.
+ IMT plugin: introduced '-i' command-line option to pmacct client tool: it
  shows last time (in seconds) statistis were cleared via 'pmacct -e'.
+ print, MongoDB & AMQP plugins: sql_startup_delay feature ported to these
  plugins.
! sql_num_hosts: the feature has been improved to support IPv6 addresses.
  Pre-requisite is definition of INET6_ATON() function in the RDBMS, which
  is the case for MySQL >= 5.6.3. In SQLite such function has to be defined
  manually.
! nfacctd: improved NF_evaluate_flow_type() euristics to reckon NetFlow/
  IPFIX event (NAT, Firewall, etc.) vs traffic (flows) records.
! fix, GeoIP: spit log notification (warning) in case GeoIP_open() returns
  null pointer.
! fix, IMT plugin: pmacct client -M and -N queries were failing to report
  results on exact matches. Affected: 1.5.0. Thanks to Xavier Vitard for
  reporting the issue.
! fix, pkt_handlers.c: missing else in NF_src_host_handler() was causing
  IPv6 prefix being copied instead of IPv6 address against NetFlow v9 recs
  containing both info.
! fix, uacctd: informational log message now shows the correct group the
  daemon is bound to. Thanks to Marco Marzetti for reporting the issue.
! fix, nfv9_template.c: missing byte conversion while decoding templates
  was causing SEGV under certain conditions. Thanks to Sergio Bellini for
  reporting the issue.
