Calculate "RamSize" needed by 16bit interface dynamically.

Calculate a LegacyRamSize directly from the e820 map for use by
handle_1588() and handle_15e801() (the only two external interfaces
that require "RamSize").  All other users of the existing RamSize (and
RamSizeOver4G) variables are specific to QEMU, so move the
declarations to paravirt.c.
