ad27615760 Netlink: attribute validation before parsing 
Wanted netlink attributes are defined in a table, specifying
their size and neediness. Removing the long conditions that did the
validation before.

Also parsing IPv4 and IPv6 versions regardless on the IPV6 macro.

9ddbfbddf8 Netlink: Allow more than 256 routing tables. 
Since 2.6.19, the netlink API defines RTA_TABLE routing attribute to
allow 32-bit routing table IDs. Using this attribute to index routing
tables at Linux, instead of 8-bit rtm_table field.

9b9a7143c4 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.

338f85ca77 IO: Handle fd values too big for select() 
If the number of sockets is too much for select(), we should at least
handle it with proper error messages and reject new sockets instead of
breaking the event loop.

Thanks to Alexander V. Chernikov for the patch.

9fdf9d29b6 KRT: Add support for plenty of kernel route metrics 
Linux kernel route metrics (RTA_METRICS netlink route attribute) are
represented and accessible as new route attributes:

krt_mtu, krt_window, krt_rtt, krt_rttvar, krt_sstresh, krt_cwnd, krt_advmss,
krt_reordering, krt_hoplimit, krt_initcwnd, krt_rto_min, krt_initrwnd,
krt_quickack, krt_lock_mtu, krt_lock_window, krt_lock_rtt, krt_lock_rttvar,
krt_lock_sstresh, krt_lock_cwnd, krt_lock_advmss, krt_lock_reordering,
krt_lock_hoplimit, krt_lock_rto_min, krt_feature_ecn, krt_feature_allfrag

c5ff44a703 KRT: Fixes learning of preferred kernel routes. 
When a new route was imported from kernel and chosen as preferred, then
the old best route was propagated as a withdraw to the kernel protocol.
Under some circumstances such withdraw propagated to the BSD kernel could
remove the new alien route and thus reverting the import.

When an interface goes down, (Linux) kernel removes routes pointing to
that ifacem but does not send withdraws for them. We rescan the
kernel table to ensure synchronization.
