- Changes most `/* comments */` to `// comments`
- Changes `/**` block comments consistently to `/*`
- Adds consistent license comments to all files
Also renames `T_POP_SET` to `T_Z80_SET`
The old "find symbol with auto scope" function is now three:
- One finds the exact name passed to it, skipping any checks
This is useful e.g. if such checks were already performed.
- One checks that the name is not scoped, and calls the first.
This is useful for names that cannot be scoped, such as checking for EQUS.
Doing this instead of the third should improve performance somehwat, since
this specific case is hit by the lexer each time an identifier is read.
- The last one checks if the name should be expanded (`.loc` → `Glob.loc`),
and that the local part is not scoped. This is essentially the old function.
This requires some special-casing for `jr @` because the `jr` opcode has
already been emitted, but not the operand, so PC points to the middle.
Moved the RGBLINK test to RGBASM's folder, and created a new RGBLINK test.
This avoids redundancy between them (and also having to port fixes and features)
The error messages have been preserved through a string reporting mechanism
Make the bool field an actual bool
Rename `iReloc` to a more exact `isKnown` (as was already pointed out by some
comments)
Make the value of `BANK(symbol)` consistent when the argument is invalid
The createpatch() function was using a fixed-size buffer. I've changed it
to be dynamically allocated. I saw that the RPN format used in patches is
slightly different from the one used internally in the assembler, so I
added a new member to the Expression struct to track the patch size.
I've also limited the RPN expression length to 1MB. I realized that the
patch RPN expression could potentially be longer than the internal RPN
expression, so the internal expression would need a limit smaller than
UINT32_MAX. I thought 1MB would be a reasonable limit.

The bank of a section can be requested with `BANK("Section Name")`, and
the bank of the current section with `BANK(@)`. In both cases, the bank
number is resolved by the linker.
New commands have been added to the list of RPN commands of object
files, and the rest has been moved so that new additions don't force a
new change in the number of the enumerations.
Increase object file version, as it is now incompatible with the old
format.
Update manpages to reflect the new ways of using `BANK()` and the new
format of the object files.

Not all occurrences have been replaced, in some cases they have been
left as they were before (like in rgbgfx and when they are in the
interface of a C standard library function).

They work with the 16-bit registers BC, DE and HL, returning the
corresponding 8-bit register. HIGH() works with AF as well, returning A.
They also work with any kind of constant or symbol, generating a RPN
patch in the object file if the value is not defined at assembly time.
They work with macro arguments as well.

Merging lai's source with this one is very irritating because
they have different indentation styles. I couldn't find what profile
vegard used for his version, so I used these flags (which should bring
the source close to KNF):

-ci4
-cli0
