Widths and fractional widths greater than 255 would overflow a
uint8_t and wrap around to smaller values.
Total formatted lengths greater than the avilable buffer size
would overflow it and potentially corrupt memory.

This shortens the lexer by 100 lines and simplifies
access to expansion contents, since it usually needs the
deepest one, not the top-level one.
Fixes#813
GitHub's ubuntu-18.04 environment installs gcc 7.3.0.
The latest ubuntu-20.04 environment installs gcc 9.3.0.
Version 9.3.0 is incompatible with building libpng 1.6.37,
as of 2021-03-04.
Fixes#783
* Fix compatibility of rgblink -O and -t
The -t "tiny mode" option makes ROM0 cover 0x8000 bytes,
not 0x4000. The -O "overlay" option fills areas uncovered
by sections with data from an overlay file. These needed
to cooperate so that the calculated uncovered overlay size
does not exceed the actual size of the ROM.
Fixes#754
* Print link test names like asm tests do
* Make the three test.sh scripts more similar
Fixes#683 and #691
The lexer's raw mode for reading macro args already attempted
to handle semicolons inside string literals, versus outside ones
which start comments. This change reuses the same function for
reading string literals in normal and raw modes, also handling:
- Commas in strings versus between macro args
- Character escapes
- {Interpolations} and \1-\9 args inside vs. outside strings
- Multi-line string literals
Macro args now allow escaping '\', '"', and '\\'.
A consistent model for expanding macro args and interpolations,
within macro args, string literals, and normal context:
- "{S}" should always equal the contents of S
- "\1" should always act like quoting the value of \1

Deprecate PRINTT, PRINTV, PRINTI, and PRINTF
Default STRFMT("%f") to 5 fractional digits like "{f:}"
Any use of string formatting will share this default
Document the existing `ROUND`, `CEIL`, and `FLOOR` functions
Also update the trig function docs for searchability
Implement `POW` and `LOG`
Addresses part of #675
Implement ** for integer exponents
** has higher precedence than -, like Python, so -3**4 == -(3**4) == 81
