Currently, 'zfs list' and 'zfs get' commands can be slow when
working with snapshots that have a ds_props_obj. This is
because the code that discovers all of the properties for these
snapshots needs to read this object for each snapshot, which
almost always ends up causing an extra random synchronous read
for each snapshot. This performance penalty exists even if the
properties on that snapshot have been unset because the object
is normally only freed when the snapshot is freed, even though
it is only created when it is needed.
This patch allows the user to regain 'zfs list' performance on
these snapshots by destroying the ds_props_obj when it no longer
has any entries left. In practice on a production machine, this
optimization seems to make 'zfs list' about 55% faster.

After spa_vdev_remove_aux() is called, the config nvlist is no longer
valid, as it's been replaced by the new one (with the specified device
removed). Therefore any pointers into the nvlist are no longer valid.
So we can't save the result of
`fnvlist_lookup_string(nv, ZPOOL_CONFIG_PATH)` (in vd_path) across the
call to spa_vdev_remove_aux().
Instead, use spa_strdup() to save a copy of the string before calling
spa_vdev_remove_aux.

Before my ZIL space optimization few years ago 128KB writes were logged
as two 64KB+ records in two 128KB log blocks. After that change it
became ~127KB+/1KB+ in two 128KB log blocks to free space in the second
block for another record. Unfortunately in case of 128KB only writes,
when space in the second block remained unused, that change increased
write latency by unbalancing checksum computation and write times
between parallel threads. It also didn't help with SLOG space
efficiency in that case.
This change introduces new 68KB log block size, used for both writes
below 67KB and 128KB-sharp writes. Writes of 68-127KB are still using
one 128KB block to not increase processing overhead. Writes above
131KB are still using full 128KB blocks, since possible saving there
is small. Mixed loads will likely also fall back to previous 128KB,
since code uses maximum of the last 16 requested block sizes.

This change modifies some of the infrastructure for enabling the use of
the DTRACE_PROBE* macros, such that we can use tehm in the "spl" module.
Currently, when the DTRACE_PROBE* macros are used, they get expanded to
create new functions, and these dynamically generated functions become
part of the "zfs" module.
Since the "spl" module does not depend on the "zfs" module, the use of
DTRACE_PROBE* in the "spl" module would result in undefined symbols
being used in the "spl" module. Specifically, DTRACE_PROBE* would turn
into a function call, and the function being called would be a symbol
only contained in the "zfs" module; which results in a linker and/or
runtime error.
Thus, this change adds the necessary logic to the "spl" module, to
mirror the tracing functionality available to the "zfs" module. After
this change, we'll have a "trace_zfs.h" header file which defines the
probes available only to the "zfs" module, and a "trace_spl.h" header
file which defines the probes available only to the "spl" module.

This has the additional advantage of allowing us to use the FPU
