While you can use zdb -R poolname vdev:offset:[<lsize>/]<psize>[:flags] 
to extract individual DVAs from a vdev, it would be handy for be able 
copy an entire file out of the pool.

Given a file or object number, add support to copy the contents to a 
file. Useful for debugging and recovery.

Before a hash table was added on top of the nvlist code, there were
cases where the nvlist allocation was changed from fnvlist_alloc()
to nvlist_alloc() to avoid expensive NV_UNIQUE_NAME checks. Now
this is no longer necessary. These changes should be reverted to be
consistent with other code. There are some cases where this change
will also reduce the number of iterations.

There is a race condition in zfs_zrele_async when we are checking if 
we would be the one to evict an inode. This can lead to a txg sync 

Instead of calling into iput directly, we attempt to perform the atomic 
decrement ourselves, unless that would set the i_count value to zero. 
In that case, we dispatch a call to iput to run later, to prevent a 
deadlock from occurring.

Make the installer more useful, by allowing it to create a bootable
installation. Also, enable the menu option for ZFS-on-root.

Like arm64, RISC-V boots by UEFI only, so arm64's partedit
implementation is renamed and shared among the two platforms.

If the installer is creating a new ESP, then this directory will not
exist and the subsequent cp will fail silently. This is usually of no
consequence if /efi/freebsd/loader.efi is set up correctly.

The System Reset extension provides functions to shutdown or reboot the
system via SBI firmware. This newly defined extension supersedes the
functionality of the legacy shutdown extension.

Update the SBI code to use the new System Reset extension when
available, and fall back to the legacy one.

On i386, after 6c7a932d0b8baaaee16eca0ba061bfa6e0e57bfd, the vbefb vt
driver was no longer detected by the loader, if any kernel module was
loaded after the kernel itself.

This was caused by the parse_vt_drv_set() function being called multiple
times, resetting the detection flag. (It was called multiple times,
becuase i386 .ko files are shared objects like the kernel proper, while
this is not the case on amd64.)

Fix this by skipping the set_vt_drv_set lookup if vbefb was already

The OID is saved when we encounter CTLFLAG_SKIP so that descendants can
be skipped as well. We then must not update the skip OID until we are
out of the node. This was achieved by resetting the skip OID once the
prefix no longer matches, but the case where the OID we reset on has
CTLFLAG_SKIP was not accounted for.
