Currently lzc_receive() requires that its snapname argument is a snapshot name
(contains '@').
zfs receive allows to specify just a dataset name and would try to deduce the
snapshot name from the stream.
I propose to allow lzc_receive() to do the same.
That seems to be quite easy to implement, it requires only a small amount of
logic, it does not require any additional system calls or any additional data
from the stream.
The benefit is that the new behavior would allow to keep the snapshot names the
same between the sender and receiver at zero cost, without a need to pass the
names out of band.

This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables. The `buildkernel` and `installkernel` targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process. See build(7), config(8), and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information. Note: If you want to build and install the kernel with the `buildkernel` and `installkernel` targets, you might need to build world before. More information is available in the handbook. The kernel configuration files reside in the sys/<arch>/conf sub-directory. GENERIC is the default configuration used in release builds. NOTES contains entries and documentation for all possible devices, not just those commonly used.
