fw-cfg: support writeable blobs
Useful to send guest data back to QEMU.
Changes from Laszlo Ersek <lersek@redhat.com>:
- rebase the patch from Michael Tsirkin's original postings at [1] and [2]
to the following patches:
- loader: Allow a custom AddressSpace when loading ROMs
- loader: Add AddressSpace loading support to uImages
- loader: fix handling of custom address spaces when adding ROM blobs
- reject such writes immediately that would exceed the end of the array,
rather than performing a partial write before setting the error bit: see
the (len != dma.length) condition
- document the write interface
