Include affine.h in quat.h; remove needless decls
...
* affine.h is needed for glm_translate_make
* Remove function declarations
- glm_mat4_mulv since mat4.h is already included
- glm_mul_rot as affine-mat.h is already include
- glm_translate as affine.h is included with this change

clipspace: add initial implementations LH, RH and NO, ZO
...
Add the initial implementations of the left-handed and right-handed
coordinate systems as well as clipspace depth values of [-1, 0] and
[0, 1].

Add LH & RH_NO perspective functions
...
This commit adds functions `glm_perspective_lh_no` and
`glm_perspective_rh_no` to the code. Unit tests are added and this
commit follows the new pattern of adding the a new file per
coordinate-system and clip-space tuple.
. Makefile.am updated
. removed test/glm_cmp project stub
. unit tests include naive implementations to as well as magic number
ref-data generated by the corresponding GLM functions.
No tests run yet on Windows or Mac.

Add glm_perspective_rh_zo function + tests
...
This commit adds the RH/ZO perspective function. It does so in the new
file `cam_rh_zo.h` and further refactors the LH variant into new file
`cam_lh_zo.h`. This creates some churn in the tests and configuration
files as new test files were added as well, and all these changes found
their way into the build files.
Tests passing on Linux.

Add function glm_perspective_lh_zo
...
This commit adds the function `glm_perspective_lh_zo`, modelled on the
implementation of glm_perspective, but amended to provide a left-hand
coordinate system expected by DirectX, Metal and Vulkan (per the GLM
project's `glm/detail/setup.hpp`). It uses a clip-space of zero-to-one.
The function is tested against a longhand version of the algorithm it
seeks to implement as well as against the output of the GLM project's
`glm::perspectiveLH_ZO` function. This commit adds a new subdirectory
`test/glm_cmp` which contains a basic CMake file and `main.cpp`. An
interested user should link or copy or clone the GLM project into this
directory. The `main` function can be used to print the reference data
used so others can verify behaviour in the future, or add new literal
reference values.
