This adds two new directives: newcharmap and setcharmap.
newcharmap creates a new charmap and switches to it.
setcharmap switches to an existing charmap.
GCC has an Undefined Behavior Sanitizer (ubsan), which enables run-time
checks of undefined behaviour. It has been enabled for the `develop`
build target.
A small bug detected with it has been fixed.

Remove '-Werror' from the default make target to make it easy for
regular users of RGBDS to compile the source code. Only a few basic
warnings are left in that target.
All the warnings have been moved to a new target called 'develop'. This
target is now the one used in Travis CI to check for problems during
compilation.

-Wformat-truncation is set to 1 instead of 2 because in some cases the
return value of snprintf is used to warn about truncations but GCC still
creates a warning for it, preventing the compilation from continuing.

-Wsign-compare has been disabled because flex generates a comparison
that triggers a warning and cannot be fixed in the code.

There was only one place where `strlcat` was used, and `snprintf`
actually does a better job at what the code was trying to achieve.

It made sense to have them in different files when the toolchain
targeted systems other than the GB. Now, there are no generic and
system-specific keywords because there is only one supported system.

If the folder where the code is compiled is a valid git repository, the
version string is generated with `git describe`. If it isn't a valid
repository, a string included in the source code is used instead. This
one must be updated regularly as the toolchain is developed.

Previously, if the user wanted to modify CFLAGS, it was necessary to add
the options used in the Makefile as well, which doesn't make sense.
This patch splits CFLAGS into CFLAGS and the previously removed
REALCFLAGS so that the user can modify the arguments passed to the
compiler without having to worry about things like passing the list of
include directories.
