932dfe0562 Fix overflowing allocations in MDLMaterialLoader 
Some allocations might underallocate due to integer overflows. This
commit ensures that we are throwing an exception if the allocation size
does not fit in an unsigned int.

30f17aa206 Fix heap out-of-bounds write in _m3d_safestr 
While there is a 256 character limit when computing the length of the
newly allocated strength, that limit was missing when copying the
string. This commit adds a new length check in the copy loop, preventing
it from writhing out of bounds.

See https://github.com/assimp/assimp/pull/4109#issuecomment-934747675
for a discussion that this is really a comment in the exported file,
and thus the fix should be harmless.

656b0b25d8 Fix warning for array comparison 
The code previously compared two float arrays with the != operator. This is deprecated in Visual Studio 2019 and results in a warning that leads to an error when compiling with warnings as errors. Small fix to make the build work.

5895c0c22c more const in format detection 
BaseImporter::SearchFileHeaderForToken() expected a pointer to a non-const token list. This was probably an oversight, as nobody would realistically expect the function to change the list. Furthermore, it prevented token lists from being compiled to read-only memory, in some cases even causing the compiler to generate thread-safe initialization.

The list is now const and all callers declare their token lists static const, thus compiling them to read-only memory.
