aa2e2bdaf2 Modify nvlist_get_parent() API to take additional cookie argument. 
This allow for non-recursive iteration over nested nvlists, as in documented
example.

00294559aa If moving descriptor or binary data to an nvlist fails, we need to close the 
descriptor or free the memory before returning.

Submitted by:	Mariusz Zaborski <oshogbo@FreeBSD.org>

While here, protect errno, so it won't be overwritted by close(2) or free(3).

8018334b70 Fix problem on big endian systems introduced in r271579 - when we were 
returning from handling a nested nvlist we were resetting big-endian flag.

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.

36da5199bb Bring in libnv library for managing name/value pairs. The following types 
are currently supported:

- NV_TYPE_NULL - only name, no data;
- NV_TYPE_BOOL - boolean (true or false);
- NV_TYPE_NUMBER - 64bit unsigned integer;
- NV_TYPE_STRING - C string;
- NV_TYPE_NVLIST - nested nvlist;
- NV_TYPE_DESCRIPTOR - file descriptor;
- NV_TYPE_BINARY - binary data.

For detailed documentation and examples see nv(3) manual page.
