Convert int* references to FX_STRSIZE

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.
