2017-12-17Declare non-local variables as const where possibleAaron Puchert
Having non-const variables of static lifetime or even global scope is usually a bad idea. These variables are inherently constants, and this should be enforced. This required marking some functions as not modifying input parameters and marking some pointers as pointers to const. One advantage is that the compiler usually puts const static variables in a read-only code segment, so they can't be modified physically. This can be verified with `nm` (on POSIX systems). To avoid changes to the public API, functions returning non-const pointers to data tables were left intact, but the returned data may not be modified. Internally we prefer using the proj_list_* functions over the pj_get_*_ref functions, because the former return const pointers.

2016-05-28Change math constants, similar to PR #372. Use M_ namespace with the de ↵Micah Cochran
facto standard M_PI and its ilk. Change names that are widely used in the project to be in the M_ namespace, so HALFPI becomes M_HALFPI. HALFPI is #defined as M_PI_2 (the defacto standard name). #defines _USE_MATH_DEFINES for MS Visual Studio (I didn't personally test this part, but Appveyor will not build otherwise).
