Saran Tunyasuvunakool 2ebc5f097b Change simulate plugin directory name to mujoco_plugin.
This helps distro packagers avoid having to create a directory with the generic `plugin` name in system locations.

Yuval Tassa 834e8dd506 Improvements to time synchronisation in simulate.
- Improved time-sync logic readability in `PhysicsLoop`.
- Fixed unattainable condition for breaking from stepping loop if data was reset.
- Added measurement of actual real-time tracking.
- Moved slowdown overlay to top left.
- Report slowdown as % of real-time, rather than fraction.
- Report actual slowdown if different than requested (very small timestep, PhysicsLoop cannot keep up) by more than 10%.
- Replaced slowdown increments of 2 with decimal-rounded increments of 10^(1/10). This is a finer-grained scale (approximately 3x as fine) and well suited for decimal percentage representation.
- Maximum slowdown increased to 1000.
- Added `Simulate.refreshrate` with a default of 60Hz, in case videomode refreshrate is 0 (can occur e.g. when forwarding over X11).
- Remove realtime reporting from regular info overlay.
- Various cleanups.

Saran Tunyasuvunakool 3240596c3a Call GLFW functions via a dynamic dispatch table.
This allows us to use GLFW without needing to introduce a link-time dependency on the library, which in turn enables us to get GLFW through Python.
