ac309bbd9e avra: rename AGAIN, to AGAIN?, 
AGAIN, becomes a shortcut for "' RJMP AGAIN?,"

7a41c5c6f9 avra: add IF, .. THEN, 
I decided to keep SKIP, .. TO, (renamed from AT,) around and limit
IF, .. THEN, to the simple BRNE case.

8bbd29d37d avra: add SKIP, .. AT, 
Will change to IF, .. THEN, but I need a way to easily reverse a
BR op. But from this commit, the translation of sms/kbd/ps2ctl.asm
is complete! perfect binary match!

7b7e60ed4a avra: implement LD/ST 
Still making great progress on sms/kbd/ps2ctl. Still matching ref
binary.

e0bc14e55c avra: implement BR* 
Getting good! still advancing on ps2ctl in sms/kbd and still
matching reference binary.

cdddfdefae avra: add a layer of indirection to FLBL! 
This will make it easier to fit BR* in there.

Still binary matching. Next step is branching support.

So far, the resulting binary matches.

ca60685067 Streamline initialization process 
Instead of letting each configuration taking care of RDLN$ and
"CollapseOS" prompt, move this to BOOT to simplify xcomp units.

Initialization source code is now only for driver initialization.

87b51a6261 By default, allocate about 0x100 bytes for PSP+RSP 
During "make updatebootstrap", we use less than 0x20 bytes on the
PSP side and less than 0x40 bytes on the RSP one. 0x100 bytes ought
to be enough for anybody.

e6bac985fa Cross-compiles in a single stage! 
Finally got rid of the XPACKed core and managed to cross-compile
all core words, which greatly simplifies the bootstrapping process.

dfe474ca0e xcomp: add XCOMPILE and X[COMPILE] 
This allows us to move words like ABORT" to xcomp-core, which is
I think the last roadblock before being able to unify all drivers
into a single xcomp layer.

06a4674317 ti84: implement a-lock 
There's a bug where the first char after a-lock isn't a-modded. I
have troubles figuring it out for now. It feels like deja vu. I
think I had the same problem with asm.

Pushed all words directly interfacing with ports and memory offsets to
low level layers. This saves us the need for keeping those variables in
runtime memory.
