Cleaned up the stdint.h header.
Separated macros from the typedefs, removed macros for unsigned minima as these are not part of the standard. Added intptr_t/uintptr_t types. Added some comments what those types stand for. Added a note that this header is mostly compiler/arch specific and should be handled (adapted) like this. git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8919 a95241bf-73f2-0310-859d-f6bbb57e9c96
