* AC: Support Double-Sided Faces
The AC format marks double-sided SURF elements with the 0x20 flag, which Assimp ignored. This commit adds support for double-sided faces.
On encountering a double-sided face via the flag mentioned above, the front face is generated as usual but is then duplicated. The winding order of the duplicate is flipped to form a back face. Vertices are duplicated too so that back faces work correctly with normal vector generation and face smoothing.
* Add test file
* Simplify test case

* Prefix MTL textures with the MTL directory path.
Path to textures defined in MTL files are relative to the MTL
file rather than to the OBJ, so we need to prefix them with the
MTL file directory path.
* Adding test issue 2355
* Trying to fix for Windows when file has Linux path

Allows to export unlimited (more than 4) bones per vertex
Use JOINTS_1,2,.. and WEIGHTS_1,2,...
Added AI_CONFIG_EXPORT_GLTF_UNLIMITED_SKINNING_BONES_PER_VERTEX flag
The omitted vertex colors are treated as (0, 0, 0, 1).
e.g
v 0.0 0.0 0.0
v 0.0 0.0 1.0 0.0 0.0 0.0
v 0.0 1.0 0.0
v 1.0 0.0 0.0 1.0 0.6 0.3
v 1.0 1.0 0.0
The pointer to a newline could not advance enough, when the line ended with \r\n. The resulting buffer was correct, as the buffer range went from <start> until \r, but that the pointer increased by just 1 could lead to the problem that the next pointer points at \n, which is still part of the newline and therefore, "getNextBlock" got 1 byte too much.
