Hi all!

I need some fields of BDRVNBDState to be available in nbd-client.c
code for my nbd-reconnect series. This leads to the following idea:
It seems that there is no actual benefits in splitting
NBDClientSession out of BDRVNBDState and nbd-client.c out of nbd.c
It only increases confusion around nbd client architecture, and make
it different from other formats. So, I propose to merge them back.

The only thing I doubt in:
NBD client block driver is called "nbd", so, seems logical to keep
BDRVNBDState structure name and block/nbd.c filename. But I can't
rename all nbd_client_* handlers to nbd_*, as they start conflicting
with definitions in include/block/nbd.h (nbd_init for example). So,
for now I've kept old names, so, some handlers are nbd_* and some
nbd_client_*, which is definitely inconsistent.. So, maybe they
all should become block_nbd_ or bdrv_nbd_ or nbddrv_ or something
like this to stress that it is BlockDriver implementation, not
nbd/client.c code (separated from generic block layer). Or keep them
as is, a bit inconsistent. What do you think?
