raw-posix.c: Make GetBSDPath() handle caching options
Add support for caching options that can be specified from the command
line.
The CD-ROM raw char device bypasses the host page cache and therefore
has alignment requirements. Alignment probing is necessary so only use
the raw char device if BDRV_O_NOCACHE is set.
This patch fixes -cdrom /dev/cdrom on Mac OS X hosts, where bdrv_read()
used to fail due to misaligned requests during image format probing.
