* Removed PI, and PI2 from math.h.
* Replaced all occurences with the standard macros M_PI, and M_PI_2. * Some coding style cleanup on the touched files, no other changes besides adding a missing check for a failed memory allocation. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31250 a95241bf-73f2-0310-859d-f6bbb57e9c96
