Split DHCP packet creation into two parts: creating the basic packet

Add sketch code to reassemble a DHCP packet from our internal "everything

We need this code in order to be able to return a DHCP packet to a PXE NBP

server). This is expensive, but necessary. Having paid this cost, we may
as well try to use the same code to generate our DHCP request packets,

the existence of a local network-layer address.

ATA devices are now asynchronous. The ATA layer itself now performs the

async_wait(), though we may wish to move this higher up the stack, and

async_done() before returning; async_wait() will work seamlessly in this
situation).

Michael Brown
3b525385af
Removed REAL_FRAGMENT and REAL_CALL, and left just REAL_EXEC (which is
...
the only one we actually use). This allows REAL_EXEC fragments to
contain proper references to constraints (e.g. "%w0"), rather than having
to force the use of specific registers.
Note that the "num_constraints" parameter is now completely obsolete, and
that we can probably reduce the syntax to something like
__asm__ __volatile__ ( REAL_CODE ( "asm statements" )
: output constraints
: input constraints
: clobber );
which would look much more natural, and avoid the need to always specify
a clobber list.
Add userptr_t to libkir.h, to allow it to at least compile.

Allow vcprintf() to be called by external code such as the curses library.
...
Also trim another eight bytes from vsprintf.o. :)

Added (untested) support for ATA devices. This code should be generic
...
enough to support both real IDE chipsets and AoE.

Refactored to reduce code size; now down from 1304 to 1105 bytes.
...
Tidied up debug messages; the log now contains one line per INT 13
operation, looking like
INT 13,08 (80): Get drive parameters
INT 13,02 (80): Read: C/H/S 0/47/14 = LBA 0xb9e <-> 1084:0000 (count 106)

Use insb/outsb; it's marginally faster.

READ CAPACITY (16) turns out to be an optional command (even though
...
READ(16) is mandatory); we must use READ CAPACITY (10) first and then
use READ CAPACITY (16) if the READ CAPACITY (10) returns "out of range".

Expert advice tells me that we *do* have to explicitly state the
...
options even when we want to use the defaults.

- made some of the bit shifting attribute access simpler (in my mind)
...
- added extern declarations for global vars
- removed comments from static inlines (too time consuming to do them
all, considering all so far have been due to the ridiculous amount of
redundancy within the API spec)
- removed a few more extern func decls for funcs that cannot be
implemented at this time
