COMMON: Move definition of math constants to scummsys header.
...
This should have no effect on common/math.h as scummsys is included at
the top anyway, but this will fix compilation on some toolchains when
strict ANSI language compliance is enabled i.e. -std=c++11, rather than
-std=gnu11.
This causes an issue as a side effect is to set a guard which disables
various non-standard defines in the system headers i.e. the M_PI and
M_SQRT1_2 constant definitions in the MinGW x86_64 toolchain on
buildbot.
By moving this into scummsys.h after the point of system math.h
inclusion, we can ensure that M_PI etc. are always present.

COMMON: Limited gcc specific intLog2 to gcc 3.4 or newer.
...
Older gcc versions did not include __builtin_clz, which made the PS2 port
fail to compile, since it uses 3.2.2.

COMMON: Move cosine/sine tables out of header files

COMMON: Renamed Integer Log2 function from log2 to intLog2.
...
This avoids naming collisions with system libraries on some platforms
i.e. DS, DC where the log2 is realised by macro.
