Remove or use unused macros
Some macros seemed to be leftover from earlier code, so I removed them.
Others seemed like they should have been used, but weren't.
There should be no functional change, except the following: in floating-
point arithmetic, x / y is not the same as x * (1.0 / y). It can be
argued that using the multiplication is significantly faster, and the
algorithm is approximative anyway. Otherwise, the constants are
obviously not required.
Also fixes one location in PJ_aitoff.c, where an enumeration value
should have been used.
