Renamed log() to log_msg(), but still keeping the old name as a macro.

This is done to avoid clashes with gcc-3.3 which has built-in logarithms :)

Rewritten the I/O loop. All socket operations are now safe, meaning that
...
you can delete the socket from anywhere in the hooks and nothing should break.
Also, the receive/transmit buffers are now regular xmalloc()'ed buffers,
not separate resources which would need shuffling around between pools.
sk_close() is gone, use rfree() instead.

IP address formatting now uses the same rules as formatting of strings
...
with two exceptions:
o Any non-zero field width is automatically replaced by standard
IP address width. This hides dependences on IPv4/IPv6.
o %#I generates hexadecimal form of the address.
Therefore |%I| generates unpadded format, |%1I| full size flush-right,
and |%-1I| full size flush-left format.

Basic support for IPv6. The system-dependent part doesn't work yet,

but the core routines are there and seem to be working.
o lib/ipv6.[ch] written
o Lexical analyser recognizes IPv6 addresses and when in IPv6

o Router ID must be configured manually on IPv6 systems.
o Added SCOPE_ORGANIZATION for org-scoped IPv6 multicasts.
o Fixed few places where ipa_(hton|ntoh) was called as a function

Use dmalloc instead of EFence when available (dmalloc has lot of improvements

over EFence and also hopefully smaller memory overhead, but sadly it's non-free

If the DMALLOC_OPTIONS environment variable is not set, switch on `reasonable'

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

Finer grained logging levels:

#define L_DEBUG "\001" /* Debugging messages */

#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.
