Fix cast from void* to epicsUInt32 loses precision

[tboegi]

Fix the compiler error on Windows64:
cast from ‘void*’ to ‘epicsUInt32 {aka unsigned int}’ loses precision

Introduce epicsUInt64 in the same way that asyn does it and use it
to look at the low-bits of address-pointers.

Some of the code added to motorOmsCom.h looks like it isn't needed. motorOmsCom.h includes motordrvCom.h, which includes motor.h which includes these lines:

Thanks @kmpeters ; work ongoing with a new patch

Öhhm, removing the "possibly duplicated definition" gives problems
when compiling Base 3.14.12

../drvOms.cc: In function ‘RTN_STATUS omsSetup(int, void*, unsigned int, int, int)’:
../drvOms.cc:1035:10: error: ‘epicsUInt64’ was not declared in this scope
if ((epicsUInt64) addrs & 0xF)
^
../drvOms.cc:1035:23: error: expected ‘)’ before ‘addrs’
if ((epicsUInt64) addrs & 0xF)

Is that because these lines were removed too?

motorOms/omsApp/src/drvOmsCom.h

Lines 48 to 53 in bb89068

	#if LT_EPICSBASE(3,15,0,2)
	#if __STDC_VERSION__ < 199901L
	typedef long long epicsInt64;
	typedef unsigned long long epicsUInt64;
	#endif
	#endif

Those do not appear in motor.h

Now there is a new version pushed;
Probably the version that I should have done from the beginning
