This function is not required, users can check it with `GetGamepadName()`

* Add DrawCylinderEx and DrawCylinderWiresEx

* Modify examples/models/models_geometric_shapes.c to show the
usage of DrawCylinder(Wires)Ex

* Simplified DrawCylinder and DrawCylinderWires to use the -Ex versions.

* This reverts commits f49b2598dd and
4542b32e4e.

* Fixed formatting.
Renamed base_angle to baseAngle.
Remove most of the raymath.h calls.

raylib was using `stb_perlin.h` library to generate perlin noise, it seems that recently this library has been flagged as it could be infringing some algorythm patent. For security, it has been removed from raylib.

* Add function DrawCubeTextureRec

* Add EOF newline

* Remove unneeded example

LoadModelAnimations takes an `int` for the animation count parameter.
The animation count should never be negative, so it makes sense to
specify it as unsigned in the API. This matches the API for
UnloadModelAnimations, which expects an unsigned int. Both GLTF and IQMM
also store the animation count internally as unsigned, and we were
casting to a signed int for no reason.

GLTF actually uses `size_t` internally, so we're technically risking
overflow, but having 2^32 animations seems unlikely.

* Add `up` argument to `DrawBillboardPro`

* Replace tab with proper spaces

Specifying a fixed seed for the random number generator is often
used in games for various reasons.

By adding an api function for seeding the random number generator
we solve two different problems regarding the seeding:

1) The underlying RNG implementation does not leak to client code
   (as would be the case if we called srand directly from the
   client code)
2) Seeding the RNG would be simple from other programming languages
   (especially in cases where calling libc functions is non-trivial)

- ADDED: `GetTouchPointCount()` to core module, removed from gestures module.
 - Support multiple touch points: `MAX_TOUCH_POINTS`.

RENAMED: GetCodepointsCount() -> GetCodepointCount()
RENAMED: GetTouchPointsCount() -> GetTouchPointCount()

As far as next raylib version will be 4.0, no backward compatibility hacks will be maintained.

This is a big change for optimization and a more professional understanding of audio. Instead of dealing with samples, now we deal with frames, like miniaudio does, so, avoiding continuous conversions from samples to frames.

Several breaking changes have been done lately so I think it's better to mark raylib for next release as 4.0.

Note that `extern "C"` calling convention only affects objects that need to be seen by the linker, in our case only functions... but it would also be required by global variables exposed, if any.

This commit introduces some breaking changes for library consistency, hopefully not too dramatic... Here the full list:
 - RENAMED: struct `CharInfo` to `GlyphInfo`, actually that's the correct naming for the data contained. It contains the character glyph metrics and the glyph image; in the past it also contained rectangle within the font atlas but that data has been moved to `Font` struct directly, so, `GlyphInfo` is a more correct name.
 - RENAMED: `CodepointToUtf8()` to `CodepointToUTF8()`, capitalization of UTF-8 is the correct form, it would also require de hyphen but it can be omitted in this case.
 - RENAMED: `TextToUtf8()` to `TextCodepointsToUTF8` for consistency and more detail on the functionality.
 - ADDED: `GetGlyphInfo()` to get glyph info for a specific codepoint
 - ADDED: `GetGlyphAtlasRec()` to get glyph rectangle within the generated font atlas
 - Some additional tweaks for consistency

- DrawTextRec() and DrawTextRecEx() have been moved to example, those functions could be very specific depending on user needs so it's better to give the user the full source in case of special requirements instead of allowing a function with +10 input parameters.

I think it is useful to know what the empty behavior is in cases where
you are enumerating key presses (e.g. implementing "press any key to
continue").
