5cbebfc940 Real almost-lockless feeds and more pull-like exports
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.

1b064355f7 Client: Add support for completion of command options
We can easily extend command completion to handle also keywords for

9ca86ef69c MPLS: Add support for per-VRF labeling policy
The new labeling policy MPLS_POLICY_VRF assigns one label to all routes
(from the same FEC map associated with one VRF), while replaces their
next hops with a lookup to a VRF table. This is useful for L3VPN
protocol.

333ddd4f98 MPLS subsystem
The MPLS subsystem manages MPLS labels and handles their allocation to
MPLS-aware routing protocols. These labels are then attached to IP or VPN
routes representing label switched paths -- LSPs.

There was already a preliminary MPLS support consisting of MPLS label
net_addr, MPLS routing tables with static MPLS routes, remote labels in
next hops, and kernel protocol support.

This patch adds the MPLS domain as a basic structure representing local
label space with dynamic label allocator and configurable label ranges.
To represent LSPs, allocated local labels can be attached as route
attributes to IP or VPN routes with local labels as attributes.

There are several steps for handling LSP routes in routing protocols --
deciding to which forwarding equivalence class (FEC) the LSP route
belongs, allocating labels for new FECs, announcing MPLS routes for new
FECs, attaching labels to LSP routes. The FEC map structure implements
basic code for managing FECs in routing protocols, therefore existing
protocols can be made MPLS-aware by adding FEC map and delegating
most work related to local label management to it.

f5140d1027 Conf: Allow keywords to be redefined by user symbols
Most syntactic constructs in BIRD configuration (e.g. protocol options)
are defined as keywords, which are distinct from symbols (user-defined
names for protocols, variables, ...). That may cause backwards
compatibility issue when a new feature is added, as it may collide with
existing user names.

We can allow keywords to be shadowed by symbols in almost all cases to
avoid this issue.

This replaces the previous mechanism, where shadowable symbols have to be
explictly added to kw_syms.

fc3547880a Filter: Add bytestring type
- Rename BYTESTRING lexem to BYTETEXT, not to collide with 'bytestring' type name
 - Add bytestring type with id T_BYTESTRING (0x2c)
 - Add from_hex() filter function to create bytestring from hex string
 - Add filter test cases for bytestring type

a8a64ca0fe Conf: Improve handling of keywords
For whatever reason, parser allocated a symbol for every parsed keyword
in each scope. That wasted time and memory. The effect is worsened with
recent changes allowing local scopes, so keywords often promote soft
scopes (with no symbols) to real scopes.

Do not allocate a symbol for a keyword. Take care of keywords that could
be promoted to symbols (kw_sym) and do it explicitly.

6cfe2066ab Higher export settle times when route refresh is running.
This helps the route refresh procedures to finish or at least
do more work before the exporters jump in and steal all the CPU time
for themselves.

dd786e338c ROA subscriptions are also converted to export requests.
By this, the requesting channels do the timers in their own loops,
avoiding unnecessary synchronization when the central timer went off.

This is of course less effective for now, yet it allows to easily
implement selective reloads in future.
