Refactor compat53 and compat53.module Lua modules.

The new compat53.module module contains only changes that don't affect
other files, and it is supposed to be used in modules like this:

    local _ENV = require( "compat53.module" )
    if setfenv then setfenv( 1, _ENV ) end

compat53.module does not change string/file metatables, and it also
doesn't support yielding from (x)pcall.

The compat53 module copies all functions from compat53.module to the
global environment, and additionally sets string/file metatables and
implements yieldable (x)pcall.
