The restart timer was racy and didn't allow for immediate restarts
from limits. Now the protocols stores the last restart time and in case
of too frequent autorestarts caused by exceeded limits, the protocol
gets disabled with an error message.
Also now there is a configuration knob for this.
Adds ability to override time format of show commands for current CLI session
so that it does not depend on configuration and may ease parsing when CLI is
called from tools.
Minor changes by committer.
The original algorithm assumed principles not consistent with the RFC
and could have lead to false invalids.
Also added filter tests showing also how the ASPA literals are used in
the static protocol.
Enum types existed on semantic level, but not on syntactic level,
so they could not be used in filter code.
Generate filter grammar for enum types based on CF_ENUM() declarations.
Thanks to lbz for the bugreport.
There is an IP table for every ROA table, holding special records
combining all known ROAs for every top-prefix.
The ROA digestor is now an IP digestor, running over the auxiliary
table.
Channel is now just subscribing to yet another journal announcing
digested tries from the ROA table.
Creating tries in every channel on-the-fly was too slow to handle
and it ate obnoxious amounts of memory. Instead, the tries are
constructed directly in the table and the channels are notified
with the completed tries.
The delayed export-release mechanism is used to keep the tries allocated
until routes get reloaded.
In future, this and rtable's data structures should be probably merged
but it isn't a good idea to do now. The used data structure is similar
to rtable -- an array of pointers to linked lists.
Feed is lockless, as with all tables.
Full export (receiving updates) is not supported yet but we don't have
any method how to use it anyway. Gonna implement it later.
Introducing a new omnipotent internal API to just pass route updates
from whatever point wherever we want.
From now on, all the exports should be processed by RT_WALK_EXPORTS
macro, and you can also issue a separate feed-only request to just get a
feed and finish.
The exporters can now also stop and the readers must expect that to
happen and recover. Main tables don't stop, though.
Move bfd_opts grammar inside BFD parser code to avoid dependences between
nest and BFD grammars, which breaks when BFD build is disabled.
Add dummy bfd_opts grammar rule, so protocols can use this nonterminal
even with BFD disabled.
Thanks to Yuri Honegger for the bugreport.

Keywords and attributes are split to separate namespaces, to avoid
