Removed incorrect comment; malloc() is inefficient only when the
alignment and size are both powers of two, and there's no way to
specify an alignment through the malloc() interface anyway.

Updated memory allocator to improve support for unaligned or partially
aligned blocks.
Moved header to include/malloc.h, since we now also provide the
POSIX-like malloc()/free() pair.
Not yet tested.

Add __constant_flsl(), because it's useful for finding out the next
power-of-two up from a given constant via
( 1 << fls ( constant - 1 ) )
fls(), flsl(), ffs() and ffsl() appear in strings.h according to
POSIX.

gcc is rather over-aggressive about optimising out static data structures
even when __atribute__ (( unused )) is correctly set...

(librm_base-1b) is already an offset; no need to apply OFFSET().
Doing so, in fact, seems to expose an assembler bug; (a-b-0) is
apparently not the same as (a-b). Go figure.

Header rearrangement.
I want to get to the point where any header in include/ reflects a
standard user-level header (e.g. a POSIX header), while everything that's
specific to gPXE lives in include/gpxe/. Headers that reflect a Linux
header (e.g. if_ether.h) should also be in include/gpxe/, with the same
name as the Linux header and, preferably, the same names used for the
definitions.

Network API now allows for multiple network devices (although the
implementation allows for only one, and does so without compromising on
the efficiency of static allocation).
Link-layer protocols are cleanly separated from the device drivers.
Network-layer protocols are cleanly separated from individual network
devices.
Link-layer and network-layer protocols are cleanly separated from each
other.

Remove the concept of the media-independent link-layer header and replace
it with metadata in the pkb structure. This is required since UNDI will
want to be able to parse the link-layer header without destroying it.

Moved if_ether.h and if_arp.h to include/gpxe, for consistency with Linux

Removed obsolete struct arprequest from if_arp.h and put it in nic.c so
that nic.c will still compile. ARP will very shortly be handled by
net/arp.c instead.
