sh: Fix executing wrong command with ${unsetvar#$(cmdsubst)}$(cmdsubst).
The parsed internal representation of words consists of a byte string with a
list of nodes (commands in command substitution). Each unescaped CTLBACKQ or
CTLBACKQ | CTLQUOTE byte corresponds to an entry in the list.
If param in ${param#%##%%word} is not set, the word is not expanded (in a
deviation of POSIX shared with other ash variants and ksh93). Erroneously,
the pointer in the list of commands (argbackq) was not advanced. This caused
the wrong command to be executed later if the outer word contained another
command substitution.
Example:
echo "${unsetvar#$(echo a)}$(echo b)"
wrote "a" but should write "b".

This change just does cleanups missed in r56043 17 years ago. The
default attributes were still stored in structs for the purpose of

Handle fifo size differences between older and newer revs of pl011 hardware.
Starting with rev 5 (which is inexplicably indicated by a version number
of '3' in the Peripheral ID register), the pl011 doubled the size of the

variables in the softc accordingly.
An interesting wrinkle in this otherwise-simple concept is that the
bcm2835 SoC, used in Raspberry Pi systems among others, has the rev 5
pl011 hardware, but somehow also has the older 16-byte fifos. We check

get_clones_stat() could be very slow if a snapshot has many (thousands) clones.
Clone names are added to an nvlist that's created with NV_UNIQUE_NAME.
So, each time a new name is appended to the list, the whole list is searched
linearly to see if that name is not already in the list. That results in the
quadratic complexity.
That should be easy to fix as we know in advance that we should not get any
duplicate names, so we can drop NV_UNIQUE_NAME when creating the list.
