1ce99b9cf7 MD5: Fix uninitialized pointer dereference for file with invalid vertex index (#6439) 
A segmentation fault occurred while parsing an MD5 file that contains an invalid vertex index.
The issue was caused by mScene->mMaterials not being kept in sync with mScene->mNumMaterials.
As a result, the aiScene destructor could call delete on uninitialized pointers. This patch
ensures that mScene->mNumMaterials always matches the actual contents of the mScene->mMaterials
array. That way, if an exception is thrown during file import, delete is only called for
properly allocated aiMaterial objects.

e3b13a48a9 Fix incorrect FBX connection order (#6421) 
PR #6120 fixed a macro which previously prevented std::unordered_multimap
from being used during FBX import when compiled with GCC.

This caused FBX::Element properties to be stored in arbitrary order,
but the order of connections ("C" properties) in FBX files matters.
The main issue I saw was incorrect materials.

This changes the type of FBX::ElementMap to always use std::multimap
(i.e., ordered). This was the behavior for years under GCC while the
broken macro was in use. Unordered containers are still used elsewhere
in the FBX importer to benefit from their performance.

36b004e286 Fixed a heap-buffer-overflow in the Half-Life 1 MDL loader. (#6321) 
The loader attempted to read the MDL header without verifying if the input buffer was large enough.
Added a check in MDLImporter::InternReadFile_HL1 to ensure the buffer size is sufficient before proceeding with loading.

6fa9d09a97 AC: Support Double-Sided Faces (#6252) 
* 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
