2017-08-31Prevent duplicate parses of same data, in the same recursive descentRyan Harrison
When parsing if there is a loop in the data being parsed, the recursions will just keep cycling until it exhausts memory and crashes. This CL introduces a parsed set, which a reference to is passed down the descent. If the data being parsed at a specific stage of the descent is already in the parsed set, then the parse returns at that point.

2017-08-30Convert int* references to FX_STRSIZERyan Harrison
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.
