evdev: Don't initialize struct sigaction with "{ 0 }".
It causes warnings on some platforms, depending on the actual definition of
sigaction, and since this is static data, it'll be zero'd out anyhow.

evdev: On sudden termination, make sure keyboard isn't lost (thanks, Tadek!)
"In release 2.0.6, when Linux evdev keyboard support has been moved to a
separate source file, a feature was added to disable normal keyboard event
processing to prevent "spilling" keystrokes to background virtual console.
This feature has one unpleasant side effect: if application fails to call
`SDL_Exit` before termination or crashes with fatal signal, console is left
in unusable state with keyboard not working and no possibility to switch
virtual console. If user has a chance, he can login remotely and restore
keyboard with `kbd_mode`, otherwise the only option is to reboot the machine.
This patch fixes that problem by intercepting fatal signals (with `sigaction`)
and process termination (with `atexit`), to restore keyboard state, if it
wasn't properly restored with `SDL_Exit`.
The function registered with `atexit` also restores original signal handlers,
to prevent leaving invalid handlers after SDL library is unloaded, if it was
loaded dynamically with `dlopen`.
No signal handlers or `atexit` function are installed if SDL boolean hint
`SDL_HINT_NO_SIGNAL_HANDLERS` is `SDL_TRUE`.
Additionally, if environment variable `SDL_INPUT_LINUX_KEEP_KBD` exists,
keyboard initialization function completely skips disabling keyboard. This
can be useful for debugging."
Fixes Bugzilla #4193.

Fixed bug 4094 - No SDL_TEXTEDITING after pressing Alt key on Raspberry Pi Linux
This was reproducible by running an SDL app on the console from an ssh login. In this case the terminal wasn't owned by the user running the app, so we were using the default keymap, which didn't have state transitions defined for ctrl and alt, so once we entered that state keypresses would no longer transition out of that state, nor would they generate text.
As a workaround, we'll just reset to the default shift state if that happens, which means we'll get text for keys pressed while ctrl is held down, but I don't think that's a big problem.
Note that in this case we also can't mute the keyboard, so the keypresses go to the console, which probably isn't what you want...

Implemented full evdev keyboard text support
This is based on the Linux kernel driver, and has fallback mapping tables in case we aren't connected to a virtual terminal.
