Change the underlying type for FX_STRSIZE to size_t from int. This
will make the value unsigned and thus all values in the range of the
type will be valid. This allows for the final remove of negative
length strings, but also introduces a some casting and functional
errors, since many parts of the code base assume that FX_STRSIZE is
int or another signed type. This also CL fixes these errors.

Through out the code base there are numerous places where variables
are declared using a signed integer type when interacting with the
string classes, since they assume that FX_STRSIZE is 'int'. As part of
changing the underling type of FX_STRSIZE to be unsigned, these
locations are being changed to use FX_STRSIZE. This is necessary as
part of converting the type, but has been broken off into a separate CL,
since it should be low risk.
Some related cleanups that are low risk are included as part of
this CL.

This method duplicates the behaviour of the const [] operator and
doesn't offer any additional safety. Folding them into one
implementation.
SetAt is retained, since implementing the non-const [] operator to
replace SetAt has potential performance concerns. Specifically many
non-obvious cases of reading an element using [] will cause a realloc
& copy.

The various string/byte classes support Mid(), Left(), and Right() for
extracting substrings. Mid() can handle all possible cases, but Left()
and Right() are useful for common cases and more explicit about what
is going on.
Calls like Mid(offset, length - offset) can be converted to
Right(length - offset). Calls like Mid(0, length) can be converted to
Left(length).
If the substring being extracted does not extend all the way to one of
the edges of the string, then Mid() still needs to be used.

No caller cares about the exception values anyway. Remove the unused
ones. Also use more std::unique_ptr to stop potential leaks.
