cb52ae0f26 Implement unionized sections in RGBASM 
This touched a lot more code than initially expected, for two reasons.

First, this broke a big RGBASM assumption: that sections are always being
written to at their end. This plus other problems required touching
basically the entirety of `section.c`.

Second, I tried different solutions to solve the above problem, and along
the way I cleaned up many things around. (I believe that keeping this to
"cleanup" commits yields subpar results, and since it's boring they get
postponed anyways.)

RGBLINK support still needs to be added, but this will come next.

This is an immediate fix for #492, although #342 is needed to implement the

2f466c2939 Revamp macro arg system 
This should significantly improve performance: on pokecrystal builds, perf
reported as much CPU time spent on `yyparse` as on `sym_UseNewMacroArgs`
Measurements show ~6 seconds of improvement on that codebase.

This also fixes #321, as a bonus, due to saner management!

7c8eba9fd2 Remove error message causing segfault 
This was utterly stupid. The check right above ensured that `sym` was NULL,
ergo that the argument to `yyerror` *would* segfault.

The only two call sites cannot pass a non-NULL pointer anyways, which I'm
betting is why this went unnoticed.
I did what an optimizing compiler would do anyways: remove the dead code.

4cc24f4369 Add ds cnt, byte syntax 
As suggested by https://github.com/rednex/rgbds/issues/350#issuecomment-498030458
The order `count` then `byte` was decided after some discussion:
- First argument consistent with single-arg syntax
- Intuitive at least to some people other than myself
- Consistent with other assemblers, at least ca65
