massive conversion of types.

	massive conversion of types.

	UINT4 is now uint32_t.  If <stdint.h> defines it, that's what
	we use, otherwise we set it to 'unsigned int', which is what
	UINT4 was typedef'd to be.

	Also, the 'strvalue' in the VALUE_PAIR structure is now uint8_t,
	as RADIUS network traffic is explicitely octets.  If uint8_t
	isn't defined, we define it to be 'unsigned char', which is
	the old value.
