Add assembler version of in_cksum. Thanks to ad@ for his time as

peep hole optimiser. This is 30% faster than the portable C version
for checksumming 64byte and larger mbufs and as fast as or slightly
faster for shorter mbufs (with a high variance).

Reorder the amd64 trapframe (swap rcx/r10 and add 4 spare slots after r9).
...
This allows the syscall code to pass the syscall args directly from the
trapframe instead of copying them to a separate structure.
It is still possible that some lurking code still assumes that
'struct trapframe', 'struct mcontext' and 'struct reg' all have the
registers in the same order, but I've fixed enough of them to get gdb working.

Change the way that the trap/intr/syscall frames and the __gregset_t[]
...
indexes are defined so that only a single list of the registers is used.
The code no longer relies on the two structures matching.
There should be no binary change.

Add a simple in-kernel linker, derived from FreeBSD's link_elf_obj.c. Needs
...
more work but is enough to load simple LKMs. amd64 is untested.
Locking is caller provided. This is decoupled from the LKM framework because
kernel modules need not be loaded from the file system - they could be built
into the kernel and referenced via link set.

additional kernel configs are not the way to go because they are not

memory based on overall size (useful for debugging to keep core dumps
small) or maximum address (when using devices with bus dma limits).
Contrary to REALBASEMEM and REALEXTMEM, they still use the BIOS memory
map and can therefore deal with fragmented memory.
