Owner

LL's local half of Game Control:

the gamepad moves the avatar, mouselook and flycam, and an on-screen cursor;
a remappable action table (keyboard-style bindings for pad buttons and axes);
a Me > Preferences > Game Controls panel (button glyphs via PromptFont, SIL OFL 1.1 -- keep its copyright notice).

Notes

LL refactored the flycam into an LLFlycam class and touched llkeybind / llkeyconflict, llui and LLAgentCamera.
This collides with our camera work: the third-person shooter camera (sltpscamera), VR locomotion and our flycam changes. Design it into our camera stack rather than porting it wholesale.
The legacy LLViewerJoystick (3Dconnexion / NDOF) and its floater stay. Decide whether the SDL path replaces it for regular gamepads.
Do after parts 1 and 2, once LL's 26.5 is released (released code only, with credit).

Size: about 2-3 weeks.
