Normalize property names for zfs receive
It turns out, userland is much more happy with aliased property names than the kernel is. So let's normalize those to the expected names before we pass them off. Added a test case hacked up from the other recv -o/-x test that fails on unpatched git and passes here. Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Rich Ercolani <rincebrain@gmail.com> Closes #12607 Closes #12609

# DESCRIPTION:
|

# Verify ZFS property override (-o) and exclude (-x) options work when
|
||||
# receiving a send stream, using property name aliases
|
||||
#
|
||||
# STRATEGY:
|
||||
# 1. Create a filesystem with children.
|
||||
# 2. Snapshot the filesystems.
|
||||
# 3. Create various send streams (full, incremental, replication) and verify
|
||||
# we can both override and exclude aliased properties.
