I'd be happy to have ABS_LX, ABS_LY and ABS_RX, ABS_RY, I was just
looking at what was available in input.h and what the xbox pads were
already doing. Likewise, mapping the dpad as HAT0X, HAT0Y is a little
wierd and ABS_DX, ABS_DY would probably be better.

Most game controllers these days (including ps3 and xbox/xbox 360)
have analog shoulder triggers. On Microsoft, LT and RT are analog
(0..255) and LB and RB are digital. On ps3, L1, L2, R1 and R2 are
actually pressure sensitive and are exported both as analog (0..255)
and digital; I figured we'd treat LR1 as digital, LR2 as analog. The
Wii Classic controller has L and R analog, ZL and ZR digital, though
IIRC the Classic Pro controller has L and R as digital.
Here's a complete mapping for some well known controllers:
left stick
- ps3, xbox, xbox360, wiiclassic, ouya -- left stick
right stick
- ps3, xbox, xbox360, wiiclassic, ouya -- right stick
dpad
- ps3, xbox, xbox360, wiiclassic, ouya -- dpad
shoulder analog triggers
- ps3 -- L2, R2, use pressure values
- xbox, xbox360 -- LT, RT
- wiiclassic -- L, R
- ouya -- unsure what they're called, but it has them
shoulder digital buttons
- ps3 -- L1, R1
- xbox, xbox360 -- LB, RB
- wiiclassic -- ZL, ZR
- ouya -- unsure what they're called, but it has them
face buttons (NORTH, EAST, SOUTH, WEST)
- ps3 -- triangle, circle, x, square
- xbox, xbox360 -- Y, B, A, X
- wiiclassic -- x, a, b, y
- ouya -- Y, A, O, U
stick buttons
- ps3, xbox, xbox360, wiiclassic -- left stick click, right stick click
- ouya -- unsure if this is supported,
start button
- ps3, xbox, xbox360, wiiclassic -- start
- ouya -- not present, developers are asking for one
system button
- ps3 -- playstation logo button
- xbox -- not available
- xbox360 -- glowy x button
- ouya -- system (U) button
select button -- arguable
- ps3, wiiclassic -- select
- xbox, xbox360 -- back
- ouya -- not present, developers are asking for one
