Change code and naming style, fix several bugs, removed math types.

After a while I felt that putting underscores between words was not the
best solution, so I changed the underscores to capital letters.

Fixed consistency bug between POSIX/Win32 platform in BH_FileOpen.

Removed definitions for math types (vector, matrix, etc.) due to
potential aliasing issues.
