Replace all resource occurrences of '0UL/~0UL' with '0/~0'.

Browse Source 
Summary:
The idea behind this is '~0ul' is well-defined, and casting to uintmax_t, on a
32-bit platform, will leave the upper 32 bits as 0.  The maximum range of a
resource is 0xFFF.... (all bits of the full type set).  By dropping the 'ul'
suffix, C type promotion rules apply, and the sign extension of ~0 on 32 bit
platforms gets it to a type-independent 'unsigned max'.
