98df7d778f Fix T51287: Matrix.lerp fails w/ shear 
Use interp_m4_m4m4 (wraps Eigen),
`MATH_STANDALONE` will need to be updated to support this.

81e584ed17 CMake: Use GCC7's -Wimplicit-fallthrough=5

use ATTR_FALLTHROUGH to suppress.

349cafac52 Matrix.decompose(): changed terminology, "location" → "translation" 
Matrix.decompose() should either return "location, orientation, size" or
"translation, rotation, scale". Since there are constructors for the former,
I've replaced "location" in the documentation with "translation".

The code is still the same, I just changed the documentation.

4ff0126e89 C99 is now the C standard for all our C code. 
The main new feature is mixed variable declarations and code, which can help
reduce uninitialized variables or accidental variable reuse.

Due to incomplete C99 support in VS 2013, variable length arrays are not
supported, BLI_array_alloca must still be used. The header <tgmath.h> is also
not supported.

fbca69c69a BLI_math: add mat3_normalized_to_* functions 
Many uses of matrices for rotation keep them normalized,
so no need to normalize each time.

fa2f7c69ac mathutils: Implement __hash__() functions 
- all mathutils types
- only works on frozen data (so vectors can be used in sets/dict keys)
- uses same method as CPython, (matches hashing a tuple)

9fd569a654 PyAPI: add utilities PyTuple_SET_ITEMS, Py_INCREF_RET 
Setting all values of a tuple is such a common operation that it deserves its own macro.
Also added Py_INCREF_RET to avoid confusing use of comma operator.

8106a6b75d mathutils: refactor instantiation 
remove 'type' argument, very few mathutils objects are wrapped,
add new function for creating wrapped objects.

also fixes unlikely memory leak if the data-array can't be allocated.

e44c49d89d Py Mathutils: add invert_safe() and inverted_safe() to Matrix. 
Those two mimic our BLI invert_m4_m4_safe - they add a small offset to diagonal values,
in case org matrix is degenerated, and if still non-invertible, return identity matrix.

Org patch by me, final enhanced version by ideasman42, many thanks!
