Nest: Fixes bug in missing cleanup during table removal

cleared in the old configuration, which breaks undo.

Conf: Fixes bug in symbol lookup during reconfiguration
...
Symbol lookup by cf_find_symbol() not only did the lookup but also added
new void symbols allocated from cfg_mem linpool, which gets broken when
lookups are done outside of config parsing, which may lead to crashes
during reconfiguration.
The patch separates lookup-only cf_find_symbol() and config-modifying
cf_get_symbol(), while the later is called only during parsing. Also
new_config and cfg_mem global variables are NULLed outside of parsing.

Initial commit on integrated BIRD
...
New data types net_addr and variants (in lib/net.h) describing
network addresses (prefix/pxlen). Modifications of FIB structures
to handle these data types and changing everything to use these
data types instead of prefix/pxlen pairs where possible.
The commit is WiP, some protocols are not yet updated (BGP, Kernel),
and the code contains some temporary scaffolding.
Comments are welcome.

Fix minor issue in pipe route propagation

these stale routes by flush process when source protocols are shut down.
This patch is a cleaner fix and allows to simplify the flush process

Better support for multitable protocols.
...
The nest-protocol interaction is changed to better handle multitable
protocols. Multitable protocols now declare that by 'multitable' field,
which tells nest that a protocol handles things related to proto-rtable
interaction (table locking, announce hook adding, reconfiguration of
filters) itself.
Filters and stats are moved to announce hooks, a protocol could have
different filters and stats to different tables.
The patch is based on one from Alexander V. Chernikov, thanks.

Fixes a tricky bug in the pipe protocol.

When uncofiguring the pipe and the peer table, the peer table was
unlocked when pipe protocol state changed to down/flushing and not to

the routes from the pipe were flushed.
The fix leads to adding some pipe-specific hacks to the nest,

which caused that hash table in BGP does not work correctly and
some routes were sent with different attributes.

A change in OSPF and RIP interface patterns.
...
Allows to add more interface patterns to one common 'options'
section like:
interface "eth3", "eth4" { options common to eth3 and eth4 };
Also removes undocumented and unnecessary ability to specify
more interface patterns with different 'options' sections:
interface "eth3" { options ... }, "eth4" { options ... };

Rewrite of buggy AS path matching.
...
Old AS path maching supposes thath AS number appears
only once in AS path, but that is not true. It also
contains some bugs related to AS path sets.
New code does not use any assumptions about semantic
structure of AS path. It is asymptotically slower than
the old code, but on real paths it is not significant.
It also allows '?' for matching one arbitrary AS number.

Fixes broken cryptographic authentication in OSPF
...
Cryptographic authentication in OSPF is defective by
design - there might be several packets independently
sent to the network (for example HELLO, LSUPD and LSACK)
where they might be reordered and that causes crypt.
sequence number error.
That can be workarounded by not incresing sequence number
too often. Now we update it only when last packet was sent
before at least one second. This can constitute a risk of
replay attacks, but RFC supposes something similar (like time
in seconds used as CSN).

Fixes bug in pipe route filtering.
...
Routes comming through pipe from primary to secondary table were
filtered by both EXPORT and IMPORT filters, but they should be
only filtered by EXPORT filters.

Better handling of AS4 optional attribute errors
...
AS4 optional attribute errors were handled by session
drop (according to BGP RFC). This patch implements
error handling according to new BGP AS4 draft (*)
- ignoring invalid AS4 optional attributes.

Fixes bug in protocol state machine
...
Scheduling flush must be done before resource pool freeing as it
frees some allocated list nodes from a global list.

Fixes core state machine.
...
The core state machine was broken - it didn't free resources
in START -> DOWN transition and might freed resources after
UP -> STOP transition before protocol turned down. It leads
to deadlock on olock acquisition when lock was not freed
during previous stop.
The current behavior is that resources, allocated during
DOWN -> * transition, are freed in * -> DOWN transition,
and flushing (scheduled in UP -> *) just counteract
feeding (scheduled in * -> UP). Protocol fell down
when both flushing is done (if needed) and protocol
reports DOWN.
BTW, is thera a reason why neighbour cache item acquired
by protocol is not tracked by resource mechanism?

Fixes race condition leading to memory corruption and crash.
...
When protocol started, feeding was scheduled. If protocol
got down before feeding was executed, then function
responsible for connecting protocol to kernel routing
tables was called after the function responsible for
disconnecting, then resource pool of protocol was freed,
but freed linked list structures remains in the list.

Fix bugs in OSPF MD5 authentication. First bug is that default
...
values for MD5 password ID changed during reconfigure, Second
bug is that BIRD chooses password in first-fit manner, but RFC
says that it should use the one with the latest generate-from.
It also modifies the syntax for multiple passwords.
Now it is possible to just add more 'password' statements
to the interface section and it is not needed to use
'passwords' section. Old syntax can be used too.

option according to RFC 4271.
