There are two cases:
1. if an invalid flag is passed, and
2. if a valid flag is not given a parameter.
In the case of (1), the flag is either short or long. For short flags,
optopt contains the character of the flag. For long, it contains zero,
and we can access the long flag using argv and optind.
In the case of (2), if the flag is short, optopt contains the character
of the flag. If the flag is long, the value in the 4th column of the
long_options table, for that flag, is returned.
We could case over all those values, or we could simply use argv and
optind again.
Note that in the case of something like `--resume`, which is also `-t`,
"t" will be returned if an argument is not provided; so the error
message will say `'t': argument not provided` or similar. This could be
fixed by making it so long and short options don't use the same
character flag, and then combining them in the switch/case statement,
but I didn't think the ugliness of the code would be worth the small
usability enhancement.

The deadman in ZoL didn't behave quite as it did in upstream
OpenZFS. In addition to the 2 purposes for which OpenZFS used the
zfs_deadman_synctime_ms parameter, ZoL also used it to determine how
frequently the deadman would fire once it has been triggered.
This patch adds the zfs_deadman_checktime_ms parameter to control how
frequently the subsequent checks are performed.
The deadman is now disabled for suspended pools.
As had been the case, unlike upstream OpenZFS, ZoL will not panic when
a hung IO is detected.
The module parameter documentation has been upated to include the new
parameter and to better describe the operation of the deadmen.

Closes#5695
The problem is that consumers of `libZFS_Core` that forget to call
`libzfs_core_init()` before calling any other function of the library
are having a hard time realizing their mistake. The library's internal
file descriptor is declared as global static, which is ok, but it is not
initialized explicitly; therefore, it defaults to 0, which is a valid
file descriptor. If `libzfs_core_init()`, which explicitly initializes
the correct fd, is skipped, the ioctl functions return errors that do
not have anything to do with `libZFS_Core`, where the problem is
actually located.
Even though assertions for that existed within `libZFS_Core` for debug
builds, they were never enabled because the `-DDEBUG` flag was missing
from the compiler flags.
This patch applies the following changes:
1. It adds `-DDEBUG` for debug builds of `libZFS_Core` and `libzfs`,
to enable their assertions on debug builds.
2. It corrects an assertion within `libzfs`, where a function had
been spelled incorrectly (`zpool_prop_unsupported()`) and nobody
knew because the `-DDEBUG` flag was missing, and the preprocessor
was taking that part of the code away.
3. The library's internal fd is initialized to `-1` and `VERIFY`
assertions have been placed to check that the fd is not equal to
`-1` before issuing any ioctl. It is important here to note, that
the `VERIFY` assertions exist in both debug and non-debug builds.
4. In `libzfs_core_fini` we make sure to never increment the
refcount of our fd below 0, and also reset the fd to `-1` when no
one refers to it. The reason for this, is for the rare case that
the consumer closes all references but then calls one of the
library's functions without using `libzfs_core_init()` first, and
in the mean time, a previous call to `open()` decided to reuse
our previous fd. This scenario would have passed our assertion in
non-debug builds.
5. Once the `ASSERTION` macros were enabled again, two tests from
the test suite were failing in `libzfs_sendrecv.c` at a
`ZIO_CHECKSUM_IS_ZERO` check within `dump_record()`. We now zero
the kernel filled checksums in all `dmu_replay_record`s that we
read in `cksummer()`, except the ones that are of type
`DRR_BEGIN`.
I considered making all assertions available for both debug and
non-debug builds, but I figured that it would not be appropriate if, for
example, an outside consumer of `libZFS_Core` suddenly triggers an
assertion failure because they happened to call `libzfs_core_fini()`,
even if previously the reference counter was `0`. Therefore, all the
reference counter related assertions are only enabled for debug builds,
and fd related assertions are enabled for debug and non-debug builds.
Porting notes:
- `ASSERT3S(g_refcount, >, 0);` added to `recv_impl` in
lib/libzfs_core/libzfs_core.c .

The refresh_config() calls into the kernel with ZFS_IOC_POOL_TRYIMPORT.
This ioctl returns the config of the pool in a buffer pre-allocated in
userland. The original estimate for the size is too conservative since
it doesn't account for the large size of vdev stats that are added to
the config before returning.
This fix simply increases the size of the buffer passed. This results in
a speed up of the zpool import process, and less spam in zfs_dbgmsg.

After resuming a pool the godfather zio could have both the
ZIO_REEXECUTE_NOW and ZIO_REEXECUTE_SUSPEND bits set. This
can occur if some child zios set ZIO_REEXECUTE_NOW while
other set ZIO_REEXECUTE_SUSPEND. The godfather zio can
inherit both flags in zio_notify_parent().
The child zios which assigned the ZIO_REEXECUTE_SUSPEND flag
will be removed from the godfather's child list and added to
the spa->spa_suspend_zio_root child list. While child zios
with the ZIO_REEXECUTE_NOW bit set remain being monitored
by the godfather zio.
When the godfather zio executes zio_done() the presence of
the ZIO_REEXECUTE_SUSPEND bit results in all io_reexecute
being cleared. These child zios will then not be re-executed
and instead will be destroyed and lost.
The most straight forward way to address this situation is
to only clear the ZIO_REEXECUTE_SUSPEND bit and leave the
ZIO_REEXECUTE_NOW bit set.

When importing a pool with a large number of filesystems within the same
parent filesystem, we see that dmu_objset_find_dp() takes a long time.
It is called from 3 places: spa_check_logs(), spa_ld_claim_log_blocks(),
and spa_load_verify().
There are several ways to improve performance here:
1. We don't really need to do spa_check_logs() or
spa_ld_claim_log_blocks() if the pool was closed cleanly.
2. spa_load_verify() uses dmu_objset_find_dp() to check that no
datasets have too long of names.
3. dmu_objset_find_dp() is slow because it's doing
zap_value_search() (which is O(N sibling datasets)) to determine
the name of each dsl_dir when it's opened. In this case we
actually know the name when we are opening it, so we can provide
it and avoid the lookup.
This change implements fix#3 from the above list; i.e. make
dmu_objset_find_dp() provide the name of the dataset so that we don't
have to search for it.
