7c92944860 Don't let MeshBuffer append functions shrink memory as this prevents optimizations
Couldn't allocate enough memory before appending several buffers for all of them as first append shrunk the memory again.

01588b58eb Get (more) append functions working for CMeshBuffer and CDynamicMeshBuffer
Some in CMeshBuffer got disabled in svn r1515 (before Irrlicht 1.7) without comment.
I suspect reason might have been that they are a bit unsafe and it was meant to be reworked. 
Maybe was planned to put that into MeshManipulator?
And CDynamicMeshBuffer never had them.
Anyway, it's useful stuff and having functions do nothing doesn't help. So now they do at least basic work.
Meaning - as long as index and vertex types are identical it's possible to attach meshbuffers again.
While totally ignoring things like 16-bit index overflow for now (so could be improved).
It would probably be better if attach functions had info about vertex/index types, but just keeping interface as it is/was for now.
This also fixes Bug #310 reported by Gaz.

9025fcc377 Add IMeshBuffer::getColor functions
Lazy access function - same as for all other members of S3DVertex (getPosition/getNormal/getTCoords).
Not sure why color was missing, maybe got added later?
Would probably be better to have a getS3DVertex function instead which would cover them all, but it's only some slow (but nice) helper function anyway.

c5b349ddb0 Add IMeshBufffer::clone for buffer copies, use it in CMeshManipulator::createMeshCopy
CMeshManipulator::createMeshCopy creates new meshes which have copies of the actual meshbuffers instead of copying everything into SMeshBuffers (which didn't support 32 bit or any of the other special features).

71e9798d2a Add IMeshBuffer::getType
Allows to find out which class a meshbuffer has.
I used the same kind of style as ISceneNode::getType. So using four CC codes and virtual functions (instead of type variable).

1dbab53e5a Prefer static_cast to reinterpret_cast where possible.
Just safer. Could probably do in a lot more places... another time.

0c6385cb92 Replace public header guards to avoid using indentifiers reserved by c++
Usually something like __IRR_SOME_GUARD_INCLUDED__ replaced by IRR_SOME_GUARD_INCLUDED.
Removing underscores at the end wasn't necessary, but more symmetric (probably the reason they got added there as well).
While this touches every header it shouldn't affect users (I hope).

Also a few whitespace changes to unify whitespace usage a bit.
And a bunch of spelling fixes in comments.

ffd7b63af0 API BREAKER: Replacing defines in irrTypes.h which are conflicting with c++ reserved identifier rules.
C++ has undefined behavior for identifiers starting with __ or with _ followed by an uppercase letter.
We still have many more (in IrrCompileConfig.h and in all header-guards), will likely replace those later as well.
As a workaround for users which might use irrlicht defines in their code, I've added the header irrLegacyDefines.h
Including that allows to continue using old defines for a while - or make it easier to have code which compiles 
with old and new Irrlicht library versions.
