v1->v2:
- added comment to raw_probe() [Kevin]
- fixed raw_reopen_prepare() [Paolo & Kevin]
- keeping BSDL: according to the v1 discussion, LGPLv2+ could work too,
but "but most of the block layer is BSD" [Paolo] and I haven't been
clearly instructed to switch to LGPLv2+.

v1 blurb:
Paolo asked me to write such a driver based on his textual specification
alone. The first patch captures his email in full, the rest re-quotes
parts that are being implemented.
The tree compiles at each patch. The series passes "make check-block".
"block/raw.c" is not removed because I wanted to keep it out of my
series and out of my brain.
Laszlo Ersek (7):
add skeleton for BSD licensed "raw" BlockDriver
raw_bsd: emit debug events in bdrv_co_readv() and bdrv_co_writev()
raw_bsd: add raw_create()
raw_bsd: introduce "special members"
raw_bsd: add raw_create_options
raw_bsd: register bdrv_raw
switch raw block driver from "raw.o" to "raw_bsd.o"
