I wasn't happy with existing implementation of the IO, so I decided
to change it - as a result there is no longer BH_IOOpen and BH_IOClose
and many IO operations are now optional (behind BH_IOCtl).
Finnally implemented buffered IO and fixed size memory buffer IO.
Refactored strings functions to make them use supplied string
instead of allocating new ones.
Additionally, split String/Int.c into several files to avoid define
mess that was present before.
Added tests for string to/from integers and added documentation.
While adding tests caught few bugs and shortcomings (now everything
works as expected)
Finally added StringToDouble function (should work for the majority of
the cases). Additionally fixed bug in StringFromDouble related to
incorrect rounding and added asserts (should add more asserts in the
following commits).
Also implemented some optimizations from Burger and Dybvig paper.
Added some basic geometric primitives such as planes, rays, segments
and lines (plus some extra functions like xProject, xBarycentric, Lerpf),
as well as some intersection tests between them.
Additionally, I split massive math test into smaller ones and tweaked
unit test library (testing no longer stops after first failure).
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.
Added Asan profile to help catch and fix various bugs (and indeed, there
were few of them).
Additionally, fixed bhunit macro to process arguments only once.
After some testing, I decided to ditch the DirectX approach of writing
math functions.
Additionally, I added unit tests (with reference wxMaxima calculations)
for most math functions and fixed several bugs along the way.
