To simplify the addition of new block modules, add a script that generates
include/qemu/module_block.h automatically from the modules' source code.
This script assumes that the QEMU coding style rules are followed.

From: "Gabriel L. Somlo"
Document the behavior of fw_cfg_modify_iXX() for leak-less updating
of integer-type blobs.
Currently only fw_cfg_modify_i16() is coded, but 32- and 64-bit versions
may be added later if necessary..

Hi everyone
I propose improving the current modular driver system for QEMU so it
can benefit everybody in speed and flexibility. I'm looking for other
ideas, comments, critics, etc.
- Background -
In order to speed up QEMU, I'm looking at the high number of libraries
and dependencies that it load
