Keywords and attributes are split to separate namespaces, to avoid
collisions between regular keyword use and attribute overlay.

fc9d471b36 Filter: Methods rework
Methods can now be called as x.m(y), as long as x can have its type
inferred in config time. If used as a command, it modifies the object,
if used as a value, it keeps the original object intact.

Also functions add(x,y), delete(x,y), filter(x,y) and prepend(x,y) now
spit a warning and are considered deprecated.

It's also possible to call a method on a constant, see filter/test.conf
for examples like bgp_path = +empty+.prepend(1).

Inside instruction definitions (filter/f-inst.c), a METHOD_CONSTRUCTOR()
call is added, which registers the instruction as a method for the type
of its first argument. Each type has its own method symbol table and
filter parser switches between them based on the inferred type of the
object calling the method.

Also FI_CLIST_(ADD|DELETE|FILTER) instructions have been split to allow
for this method dispatch. With type inference, it's now possible.

This is a backport cherry-pick of commits

from the v3.0 branch as we need symbol hashes directly inside their
scopes for more general usage than before.

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.

cce48c6cdd Filter: Add separate instruction for uninitialized variable declaration
The previous approach (use VOID constant for variable initialization)
failed due to dynamic type check failure.

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

1a1e13cc2f Filter: Disable some trie formatting tests
Trie formatting works slightly different with 4-way tries than with
16-way ones, so these tests generated false error. Block them for now.

7144c9ca46 Filter: Allow setting the 'onlink' route attribute in filters
Add static route attribute to set onlink flag for route next hop. Can be
used to build a dynamically routed IP-in-IP overlay network. Usage:

     ifname = "tunl0";
     onlink = true;
     gw = bgp_next_hop;

e20bef69cc Filter: Change linearization of branches in switch instruction
Most branching instructions (FI_CONDITION, FI_AND, FI_OR) linearize its
branches in a recursive way, while FI_SWITCH branches are linearized
from parser even before the switch instruction is allocated.

Change linearization of FI_SWITCH branches to make it similar to other
branching instructions. This also fixes an issue with constant
switch evaluation, where linearized branch is mistaken for
non-linearized during switch construction.

Thanks to Jiten Kumar Pathy for the bugreport.

d3f50ede12 Add compile-time option to enable 4-way tries instead of 16-way ones
In some cases 16-way tries are too memory-heavy, while 4-way are
almost as efficient as the original 2-way ones.
