1597f1e131 Don't generalize XYPOS just yet 
It was ill-advised.

db9885b8cf Rename (find) to FIND 
I hadn't noticed that this word was almost ANS compliant.

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.

0163af470a Fix EOT behavior after QUIT 
Previously, calling quit would break EOT behavior and not properly
quit Collapse OS.

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.

bf289b0a67 z80a: de-variable-ize 
Use straight VARIABLE instead of Z80MEM+. Initially, I used this
system to allow z80a to be embedded in a system binary, but now
I don't think it's worth it. Compiled, z80a is 2.5k. Sure, it's a
sizeable amount of RAM, but I think that even with it in RAM, I'll
manage a bootstrap within my most constrained machine, the SMS with
8K.

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.

33d37d4ce9 WORD: don't overwrite RAM on words over 31 chars

9b85961093 Rename "Core words" to "XPACKed core" 
Now that this section is so small, I think I can see a possibility
for cross-compiling Collapse OS entirely, which would be great
because we could get rid of the relinker.

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.

1094ec9c57 Make DO..LOOP stable 
DO and LOOP now only compile words from stable ABI, which make them
suitable for xcomp. This will greatly simplify driver writing and
allow us to mostly avoid the low/high divide in drivers.

LEAVE is still xcomp-incompatible though.

This make us very very tight for "<0x100" limit for literal words.
Hopefully, we won't need more stuff in that area of the binary...

73482e7ea1 Reword root block 
Usage of "LIST" wasn't explicit enough for a complete newcomer. I
hope that with this wording, anyone can figure out how to navigate
blocks and learn the system.
