67bd949a52 Real implementation of protocol state machines. Delayed startup/shutdown
should work now. Initial feeding of protocols by interfaces/routes is
done from the event queue to prevent unwanted recursion.

e8f73195fa Added simple event scheduling system to avoid recursive calling
of various callbacks.

Events are just another resource type objects (thus automatically freed
and unlinked when the protocol using them shuts down). Each event can
be linked in at most one event list. For most purposes, just use the
global event list handled by the following functions:

	ev_schedule	Schedule event to be called at the next event
			scheduling point. If the event was already
			scheduled, it's just re-linked to the end of the list.
	ev_postpone	Postpone an already scheduled event, so that it
			won't get called. Postponed events can be scheduled
			again by ev_schedule().

You can also create custom event lists to build your own synchronization
primitives. Just use:

	ev_init_list	to initialize an event list
	ev_enqueue	to schedule event on specified event list
	ev_postpone	works as well for custom lists
	ev_run_list	to run all events on your custom list
	ev_run		to run a specific event and dequeue it

98e87c8628 Finer grained logging levels:
#define L_DEBUG "\001"   /* Debugging messages */
#define L_INFO "\002"    /* Informational messages */
#define L_WARN "\003"    /* Warnings */
#define L_ERR "\004"     /* Errors */
#define L_AUTH "\005"    /* Authorization failed etc. */
#define L_FATAL "\006"   /* Fatal errors */
#define L_TRACE "\002"   /* Protocol tracing */
#define L_INFO "\003"    /* Informational messages */
#define L_REMOTE "\004"  /* Remote protocol errors */
#define L_WARN "\004"    /* Local warnings */
#define L_ERR "\005"     /* Local errors */
#define L_AUTH "\006"    /* Authorization failed etc. */
#define L_FATAL "\007"   /* Fatal errors */
#define L_BUG "\010"     /* BIRD bugs */

Introduced bug() which is like die(), but with level L_BUG. Protocols
should _never_ call die() as it should be used only during initialization
and on irrecoverable catastrophic events like out of memory.

Also introduced ASSERT() which behaves like normal assert(), but it calls
bug() when assertion fails. When !defined(DEBUGGING), it gets ignored.

a6f250f5c6 New hash functions according to benchmarks posted yesterday. (The IPv6
version has not been benchmarked yet due to insufficient test data.)
Now ipa_hash() returns a uniformely distributed 16-bit value.

a05406e69c Implemented deletion/insertion/asynchronous-walk lists.
For example of their use, look at comments in lib/slists.h.

b35d72ac66 Name cleanups as suggested by Pavel:
- cfg_strcpy() -> cfg_strdup()
- mempool -> linpool, mp_* -> lp_*  [to avoid confusion with memblock, mb_*]

Anyway, it might be better to stop ranting about names and do some *real* work.

matching interface names in protocol-to-iface bindings.

53a416d376 Implemented snprintf and similar functions. It took a lot of thinking,
but the modifications were relatively simple and straightforward.

ab3a76a382 Added ipa_from_u32 and ipa_from_u32 for use in the kernel sync code (IPv4 only).
Don't ever think of using it in routing protocols.

d92882be9b WALK_LIST_DELSAFE now actually works (it really couldn't since it didn't
reference list head at all).

GCC is fixed to handle custom formats.

786d0bb9e7 Added ipa_class_mask() which guesses netmask for classful addressing.
For pure A/B/C class addresses it just returns the class netmask, for
subnets it tries to guess subnet mask. Please make sure the address
you pass to this function is really a valid host address (i.e., call
ipa_validate() first).

	%I	IP address
	%#I	IP address in hexadecimal

1feea03e74 Changed #include <x/y> to #include "x/y" for our local includes, so that
