This adds two new directives: newcharmap and setcharmap.
newcharmap creates a new charmap and switches to it.
setcharmap switches to an existing charmap.
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.

rgbasm tries to optimize any loads from/to $FF00-$FFFF and generate
LDH 2-byte opcodes instead of regular LD 3-byte opcodes. This is a bit
inconsistent as it only works for constant values. If a load is trying
to access a label in a HRAM floating section, or a section found in a
different object file, this optimization doesn't work.
This means that a simple refactor or code could allow rgbasm to perform
the optimzation or prevent it from doing so. For certain projects, like
disassemblies, this is a problem.
This patch adds flag -L to rgbasm to disable the optimization, and
doesn't change the behaviour of any other existing code.

There are two ways in which the assembly process can fail:
1. If there is a really big problem that compromises the whole process,
the assembler has to stop right there and generate an error message.
This happens with unterminated REPT loops, macros, etc.
2. If the problem isn't that big and the process can still continue,
even though the final result is invalid, the assembler can try to
continue and warn the user about all errors it finds in the code.
This patch clarifies the use of each function and replaces the function
used in two places by the correct one.

A lot of warnings are being added (and more will come) so it makes sense
to be able to disable them in legacy source that generates warnings but
is otherwise correct.

This function produces a similar output to the other error handlers, including printing to stderr, and including a stack trace. However, ‘warning’ is displayed instead of ‘ERROR’, and the compilation does not fail.
This function is now used for the deprecation warnings, ensuring that these errors can be found.
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):
-bap
-br
-ce
-ci4
-cli0
-d0
-di0
-i8

-l79
