Virgil Dupras e691dab070 zasm: little drive-by optimization
Use IX directly for argspec rows instead of going through DE. It saves a bit
of processing. The code was this way because I initially didn't use IX at all,
so as code evolved, that DE translation stayed as an artifact.

Virgil Dupras 0d7693a163 core: remove writeHLinDE
It wasn't used much so I inlined it.

Virgil Dupras 4f7a05e3b7 core: remove cpHLDE
It wasn't used much, so I replaced its use in the kernel with direct code
and moved the routine in apps/ed, the only other place where it was used.

Virgil Dupras 381d57a513 basic: make variable A the only input variable
Mechanism for assigning inputs to the specified variable is clumsy and uses
binary space. Always using A is much simpler and doesn't seem very limiting to
me. I do that because there's many more "input" commands I'd like to add.

Virgil Dupras 13f935aa88 basic: add fls command
Also, add the new `bshell` emulated tool. BASIC is on its way to replace the
shell.

Virgil Dupras b7d4860acf basic: add in/out commands
Also, fixed the cmd matching algo to not accept partial matches. For example,
to stop matching "input" when the command was "in".

Virgil Dupras 501fe96e07 lib/expr: use the IX register a bit less
It's an awkward register to use and avoiding its use allows us to strip the
resulting binary significantly. parseEXPR keeps the same signature though.

Virgil Dupras 1cea6e71e0 basic: add a print cmd
It can only print a decimal literal. But still, that's a big step because
I hadn't implemented decimal formatting yet.
