Starting from Linux 4.11, IPv6 ECMP routes are now notified using
RTA_MULTIPATH, like IPv4 ones. The patch adds support for RTA_MULTIPATH
parsing for IPv6 routes. This also enables to parse ECMP alien routes
correctly.

Thanks to Vincent Bernat for the original patch.

Incorrect structure alignment breaks kernel routing table updates on
FreeBSD/ARM (and perhaps other platforms).

Thanks to Eugene Sevastyanov for the original patch.

Add configuration and docker definitions for tests and builds in Gitlab
CI platform.

Some of them currently fail, which is a known problem.

Keep a cache of all the relevant prefixes we send out. When a prefix
appears, insert it into the cache. If it dies, keep it there for a
while, marked as dead.

Send out the dead prefixes with zero lifetime.

Put the prefix option preparation into a separate function. We're going
to reuse that bit of code.

non-primary is ugly, just omit it (and use primary in the other case).

A non-primary address isn't necessarily secondary, that's an independent
flag.

A TODO file last updated 5 years ago is useless.

Adapt the naming conventions to be a bit closer to the other protocols.

proto_radv -> radv_proto
struct radv_proto *ra -> struct radv_proto *p
struct proto *p -> struct proto *P

The old hash table had fixed size, which makes it slow for config files
with large number of symbols and symbol lookups. The new one is growing
according to needs.

Function isspace() expects to get *unsigned* chars (encoded as ints),
not that it matters for plain ASCII.

Simplify BIRD client library checks, add proper devel header checks and
prefer dependency on just tinfo than full ncurses.

Replaced by constant compile-time expressions. CPU_STRUCT_ALIGN is not
really correct, but is consistent with the old behavior.

Make indentation and quotation consistent in configure macros.
Also remove --with-sysinclude option, which was broken for 7 years
and nobody complained.

Thanks to Ruben Kerkhof for source patches.

Replace integer type width detection with C99 fixed-width types.
Also remove some unused or obsolete code.

Thanks to Ruben Kerkhof for the patchset.

The patch allows to use autoreconf, replaces some long obsolete
constructs and does some other minor cleanups. Also, the file
configure.in is renamed to configure.ac, as the old name has been
deprecated for a long time.

Thanks to Ruben Kerkhof for the patchset.

This may be useful if multple interfaces share the same network range.

Thanks to Fritz Grimpen for the original patch.

When a BGP session with ADD_PATH is restarted and the neighbor do not
announce ADD_PATH capability during reconnect, the accept_ra_types is
still set to RA_ANY.

Thanks to Lennert Buytenhek for the bugreport

Adds option 'allow bgp_local_pref' to override the usual restriction of
LOCAL_PREF on eBGP sessions.

Thanks to Lennert Buytenhek for the patch.

Thanks to Steve Leung for the bugreport.

During reconfiguration, old and new filter expressions in static routes
are compared using i_same() function. When filter expressions contain
function calls, it is necessary that old filter expressions are the
second argument in i_same(), as it is internally modified by i_same().
Otherwise pointers to old (and freed) data appear in the config
structure.

Thanks to Lennert Buytenhek for tracking and reporting the bug.

Thanks to Vincent Bernat for the patch.

FreeBSD 11 changed endianity of ip_len field from host order to network
order. Also DragonFly BSD allegedly expects network order here.

Thanks to Olivier Cochard-Labbé for the patch.
