Fix nfs snapdir automount
The current implementation for allowing nfs to access snapdir is very buggy.
It uses a special fh for snapdirs, such that the next time nfsd does
fh_to_dentry, it actually returns the root inode inside the snapshot. So nfsd
never knows it cross a mountpoint.
The problem is that nfsd will not hold a reference on the vfsmount of the
snapshot. This cause auto unmounter to unmount the snapshot even though nfs is
still holding dentries in it.
To fix this, we return the inode for the snapdirs themselves. However, we also
trigger automount upon fh_to_dentry, and return ESTALE so nfsd will revalidate
and see the mountpoint and do crossmnt.
Because nfsd will now be aware that these are different filesystems users
must add crossmnt to their export options to access snapshot directories.

OpenZFS 7793 - ztest fails assertion in dmu_tx_willuse_space

Background information: This assertion about tx_space_* verifies that we
are not dirtying more stuff than we thought we would. We “need” to know
how much we will dirty so that we can check if we should fail this
transaction with ENOSPC/EDQUOT, in dmu_tx_assign(). While the
transaction is open (i.e. between dmu_tx_assign() and dmu_tx_commit() —
typically less than a millisecond), we call dbuf_dirty() on the exact
blocks that will be modified. Once this happens, the temporary
accounting in tx_space_* is unnecessary, because we know exactly what
blocks are newly dirtied; we call dnode_willuse_space() to track this
more exact accounting.
The fundamental problem causing this bug is that dmu_tx_hold_*() relies
on the current state in the DMU (e.g. dn_nlevels) to predict how much
will be dirtied by this transaction, but this state can change before we
actually perform the transaction (i.e. call dbuf_dirty()).
This bug will be fixed by removing the assertion that the tx_space_*
accounting is perfectly accurate (i.e. we never dirty more than was
predicted by dmu_tx_hold_*()). By removing the requirement that this
accounting be perfectly accurate, we can also vastly simplify it, e.g.
removing most of the logic in dmu_tx_count_*().
The new tx space accounting will be very approximate, and may be more or
less than what is actually dirtied. It will still be used to determine
if this transaction will put us over quota. Transactions that are marked
by dmu_tx_mark_netfree() will be excepted from this check. We won’t make
an attempt to determine how much space will be freed by the transaction
— this was rarely accurate enough to determine if a transaction should
be permitted when we are over quota, which is why dmu_tx_mark_netfree()
was introduced in 2014.
We also won’t attempt to give “credit” when overwriting existing blocks,
if those blocks may be freed. This allows us to remove the
do_free_accounting logic in dbuf_dirty(), and associated routines. This
logic attempted to predict what will be on disk when this txg syncs, to
know if the overwritten block will be freed (i.e. exists, and has no
snapshots).
Porting notes:
- DNODE_SIZE replaced with DNODE_MIN_SIZE in dmu_tx_count_dnode(),
Using the default dnode size would be slightly better.
- DEBUG_DMU_TX wrappers and configure option removed.
- Resolved _by_dnode() conflicts these changes have not yet been
applied to OpenZFS.

Dump unique configurations and Uberblocks in zdb -lu
For zdb -l, detect when the configuration nvlist in some label l (l>0)
is the same as a configuration already dumped. If so, do not dump it.
Make a similar check when dumping Uberblocks for zdb -lu. Check whether
a label already dumped contains an identical Uberblock. If so, do not
dump the Uberblock.
When dumping a configuration or Uberblock, state which labels it is
found in (0-3), for example: labels = 1 2 3
Detecting redundant uberblocks or configurations is accomplished by
calculating checksums of the uberblocks and the packed nvlists
containing the configuration.
If there is nothing unique to be dumped for a label (ie the
configuration and uberblocks have checksums matching those already
dumped) print nothing for that label.
With additional l's or u's, increase verbosity as follows:
-l Dump each unique configuration only once.
Indicate which labels it appears in.
-ll In addition, dump label space usage stats.
-lll Dump every configuration, unique or not.
-u Dump each unique, valid, uberblock only once.
Indicate which labels it appears in.
-uu In addition, state which slots are invalid.
-uuu Dump every uberblock, unique or not.
-uuuu Dump the uberblock blockpointer (used to be -uuu)

The mount(8) command will helpfully try to resolve any device name
which is passed in. It does this by applying some simple heuristics
before passing it along to the registered mount helper.
Normally this fine. However, one of these heuristics is to prepend
the current working directory to the passed device name. If that
resulting directory name exists mount(8) will perform the mount(2)
system call and never invoke the helper utility.
Since the cwd for systemd when running as the system instance is
the root directory the default mount points created by zfs(8) can
cause a mount failure.

OpenZFS 7742 - zfs send wrong error message with invalid long opts
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.

OpenZFS 7745 - print error if lzc_* is called before libzfs_core_init
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 .

Fix suspend Godfather I/Os io_reexecute bits
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.

Add -Wno-declaration-after-statement to KERNELCPPFLAGS
Disable the warnings regarding ISO C90 forbidding mixed
declarations and code. While this functionality was
introduced as part of C99 gcc does allow this in C90
mode as an extension.
Allowing this usage helps minimize the changes required
when porting patches from OpenZFS. The downside here is
that this functionality is specific to gcc.
