Use memEQs, memNEs in core files

Where the length is known, we can use these functions which relieve
the programmer and the program reader from having to count characters.
The memFOO functions should also be slightly faster than the strFOO
equivalents.

In some instances in this commit, hard coded numbers are used.  These
come from the 'case' statement values that apply to them.
