'PAGE_SIZE' macro redefined

[Helmut K. C. Tessarek]

I get the following warning when I compile x265 (11084:fe65544b6c40):

/work/compile/x265/source/common/common.cpp:56:9: warning: 'PAGE_SIZE' macro redefined
#define PAGE_SIZE       (4096)
        ^
/usr/include/mach/i386/vm_param.h:99:9: note: previous definition is here
#define PAGE_SIZE               I386_PGBYTES
        ^
1 warning generated.

I'm not sure, if this is a problem, but I haven't seen this warning a week ago.

Backed out changeset: acb4cb3d7621 (fixes #201)

This is an acceptable optimization, but we need to find a more portable way to use PAGE_SIZE.
