[PATCH] xfree86: reword InputDevice man sections, deprecate CorePointer/CoreKeyboard

[Peter Hutterer]

Reshuffle and reword - InputDevice sections are only necessary if
hotplugging is disabled. Put more emphasis on hotplugging and less on HAL
since we'll switch backends eventually.

CorePointer, CoreKeyboard, and AlwaysCore should be listed as deprecated
since they don't do what they used to since 1.4. These days, only
SendCoreEvents matters and it's enabled for any driver calling
xf86ProcessCommonOptions (== every driver).
It only controls the startup behavior too, so document this.
