roms: Flush icache when writing roms to guest memory

We use the rom infrastructure to write firmware and/or initial kernel
blobs into guest address space. So we're basically emulating the cache
off phase on very early system bootup.

That phase is usually responsible for clearing the instruction cache for...

loader: use file path size from fw_cfg.h

loader: support for unmapped ROM blobs

Support ROM blobs not mapped into guest memory:
same as ROM files really but use caller's buffer.

Support invoking callback on access and
return memory pointer making it easier
for caller to update memory if necessary....

loader: store FW CFG ROM files in RAM

ROM files that are put in FW CFG are copied to guest ram, by BIOS, but
they are not backed by RAM so they don't get migrated.

Each time we change two bytes in such a ROM this breaks cross-version
migration: since we can migrate after BIOS has read the first byte but...

Bugfix for loading multiboot kernels

This patch fixes a bug in rom_copy introduced by
commit d60fa42e8bae39440f997ebfe8fe328269a57d16.

rom_copy failed to load roms with a "datasize" of 0.
As a result, multiboot kernels were not loaded correctly
when they contain a segment with a "file size" of 0....

hw/loader: Support ramdisk with u-boot header

Introduce 'load_ramdisk()' which can load "normal" ramdisks and ramdisks
with a u-boot header.
To enable this and leverage synergies 'load_uimage()' is refactored to
accomodate this additional use case.

memory: add ref/unref calls

Add ref/unref calls at the following places:

- places where memory regions are stashed by a listener and
used outside the BQL (including in Xen or KVM).

- memory_region_find callsites

- creation of aliases and containers (only the aliased/contained...

memory: make section size a 128-bit integer

So far, the size of all regions passed to listeners could fit in 64 bits,
because artificial regions (containers and aliases) are eliminated by
the memory core, leaving only device regions which have reasonable sizes...

refer to FWCfgState explicitly

Currently some places use pointer-to-void even though they mean
pointer-to-FWCfgState. Clean them up.
