When the while loop in `ParseSymbol` stops because of the symbol length,
`copied` will have the value of `MAXSYMLEN`, which is obviously not
greater than `MAXSYMLEN`. Changing the condition to `>=` fixes the
issue.
As a bonus, the correct union field will now be used. It shouldn't
matter, but it's technically UB to use a wrong one.
Currently, all symbols are assigned a filename and line when they're
first encountered and added to the internal hash table. This is often
not expected and leads to erroneous error messages.
The original list only existed because the documentation was split
across multiple files. When all keywords are described in a single
document, Ctrl+F suffices to find them.
The following mnemonics are now valid:
- ld
- ldh
- ldio
The following are valid as operands:
- [$ff00+c]
- [$ff00 + c]
- [c]
This is done for consistency with 'ld [$FF00+n],a' and variations of it.

The tests are not exhaustive, there are some conditions that aren't
checked. The tests are based in the C standard rules about undefined
behaviour.
This is a compatibility break but, hopefully, all projects are using
sane values. If not, there is no guarantee that the projects will build
in any platform where RGBDS can be compiled, so it would be better to
fix them.
Even though, technically, the left shift of a negative value is always
undefined, some projects rely on its current behaviour. This is the
reason why this doesn't cause a fatal error.

Added define 'unused_' for '__attribute__((unused))'. The oldest version
of GCC with online docs (GCC 2.95.3, released in March 16, 2001 [1])
already has support for this attribute, so it doesn't make sense to
check the version.
Renamed 'noreturn' to 'noreturn_' for consistency.
