z80a: make mnemonic names more uniform across assemblers
...
Initially, I used the same letters as those used in the z80 ref
docs, but it makes the different assemblers harder to use than they
should. Having consistent "argtype" rules across assemblers should
help.

z80: fix chkPS's "stable ABI" form in binaries with offset
...
Before lblnext is set, we need to use BJP, instead of JPnn, for the
jump to work in binaries with offsets.

z80: remove layer of indirection in most "next" calls
...
The only calls still using the stable ABI indirection are those
made before the next routine is created.

z80: use named labels for boot routines
...
The usage of numerotated labels for this was becoming severly
confusing.

Make word routines into word types
...
Instead of having wordref point to core word routines, I made them
into word 4 word types. It liberates space into the stable ABI and
should make porting to other arches easier.
I'm also thinking of combining word type with the namelen field
for precious bytes saving, but not now...

Fix recipes with binary offset (ti84, trs80)
...
I broke them when I removed call indirection layers without also
removing usage of BCALL.

z80: optimize chkPS
...
Inline it in next and make chkPS, call a newly reserved label for
it directly, removing a layer of indirection. This frees a spot in
the stable ABI.

VE: add 't'
...
This is the first commit I do entirely in VE. It's a habit I'm planning
on taking as it helps a lot to find usability issues.

Will be useful for assembling binaries for the TRS-80 which can't start
at addr 0.

Copy z80a.fs to disk blocks

I don't remove z80a.fs yet because build process needs it, but that
will change shortly.
