key remap: simplify and use movable allocations

Browse source 
Have action.c control the key remap buflib allocation so that it can
be made movable. With memory management offloaded, core_keymap.c only
needs to deal with loading keymap files. Simplify the code there and
use buflib pinning so the file can be loaded directly into the buffer.
