nbd: move socket wrappers to qemu-nbd

qemu-nbd is one of the few valid users of qerror_report_err. Move
the error-reporting socket wrappers there.

block: Add reference parameter to bdrv_open()

Allow bdrv_open() to handle references to existing block devices just as
bdrv_file_open() is already capable of.

block: Make bdrv_file_open() static

Add the bdrv_open() option BDRV_O_PROTOCOL which results in passing the
call to bdrv_file_open(). Additionally, make bdrv_file_open() static and
therefore bdrv_open() the only way to call it.

Consequently, all existing calls to bdrv_file_open() have to be adjusted...

block: Remove bdrv_open_image()'s force_raw option

This option is now unnecessary since specifying BDRV_O_PROTOCOL as flag
will do exactly the same.

block: Change BDS parameter of bdrv_open() to **

Make bdrv_open() take a pointer to a BDS pointer, similarly to
bdrv_file_open(). If a pointer to a NULL pointer is given, bdrv_open()
will create a new BDS with an empty name; if the BDS pointer is not
NULL, that existing BDS will be reused (in the same way as bdrv_open()...

We can only have a single wait_serialising_requests() call per request
