e0e2d9fe80 project: Improve Linux support (#27 and #13)
While Linux was not an original goal of the project, it should still be supported out of the box. Therefore a number of changes are contained in this changeset:

- All C++ .h files were renamed to .hpp.
- All C includes (<....h>) were replaced with C++ includes (<c...>) and missing includes were added.
- std::memset and std::memcpy was replaced with memset and memcpy.
- All anonymous structs were removed where necessary.
- `extern "C"` was removed where it wasn't needed.
- #pragma warning was placed behind an #ifdef _MSC_VER
- The macros for `min`, `max` and `clamp` were removed as they were not used.
- `-fpedantic` was added to the GCC flags for bitmask support.
- `gs::rendertarget_op` is now declared before use.
- std::exception(const char*) was replaced with std::runtime_error(const char*).
- Added aligned_alloc and aligned_free macros for GCC and MSVC support.
- Replaced use of `sprintf_s` with `snprintf`.
- Placed additional guards around windows only code.

Additonally some changes were made that do not affect Linux:
- `NOMINMAX` and `NOINOUT` were removed.

Fixes: #27
Fixes: #13

cace17a817 gs-vertexbuffer: Allow specifying amount of UV layers
This should reduce GPU memory usage for vertex buffers that need less UV information than the maximum allowed UV layers possible.

2adfa5765c gs: Rename to snake_case instead of PascalCase
This should prevent mishaps with upper/lowercase typos and fits in better with the C++ standard code, which is also in snake_case.

5e0b387dc1 gs-vertexbuffer: Functions to directly access internal buffers
Skips the previously necessary step to call At(0) and use the pointers stored in GS::Vertex to directly write to the buffers.

1ebb0beac4 gs-vertexbuffer: Avoid relying on std for aligned types
Changes the GS::VertexBuffer storage to be one continuous buffer that is properly aligned and is also now used for GS::Vertex. This halves the necessary memory, removes reallocation cost and removes the copy necessary to get things onto the GPU.

cb1ae28b07 gs-vertexbuffer: Use aligned memory and fix null pointer
This fixes the crash on creation issues, but a crash on exit still happens with the plugin installed. Unsure what exactly is causing it but it looks like something is writing into heap memory.

c7cfbff7dd gs-vertexbuffer: Workaround for a foreign deallocation bug in libobs
The graphics subsystem in OBS is freeing memory it didn't allocate, resulting in stack/heap corruption and other kinds of messy situations. The official "fix" for this is to use bmalloc, but then you lose any kind of ability to re-use the same buffer for multiple vertex buffers or update on the fly without adjusting code that is possibly outside of your control (such as in libraries).

This works around the issues by "patching" the gs_vertexbuffer object to no longer hold a reference to the gs_vb_data object. Currently only D3D11 is supported for this kind of hack and it might break in a future obs-studio release.
