Similarly to booleans and following the fix for PR python/29217 make `gdb.parameter' accept `None' for `unlimited' with parameters of the PARAM_UINTEGER, PARAM_INTEGER, and PARAM_ZUINTEGER_UNLIMITED types, as `None' is already returned by parameters of the two former types, so one might expect to be able to feed it back. It also makes it possible to avoid the need to know what the internal integer representation is for the special setting of `unlimited'. Expand the testsuite accordingly.
