1c6e90b0f8 libnv: Don't lose big-endian flag when receiving a message.
A bug caused the "big endian" flag to be lost when receiving a message. As a
result, the bits are interpreted as little endian and an extremely large
allocation is attempted.

This change fixes ping(8)'s communication to casperd(8) on big-endian
architectures.

97d1a20dfb nv(3) was not in 10.0.
It might be MFC'd to stable/10 for 10.1, but for now update the manual to
avoid confusion on its availability.

518eeaeeca MFp4 @1189139:
Get rid of the msg_peek() function, which has a problem.  If there was less
data in the socket buffer than requested by the caller, the function would busy
loop, as select(2) will always return immediately.

We can just receive nvlhdr now, because some time ago we splitted receive of
data from the receive of descriptors.
