Reduce the usage of EXTRA_DIST. If files are conditionally included in
_SOURCES, _HEADERS etc, automake is smart enough to dist all files that
could possibly be included, but this does not apply to EXTRA_DIST,
resulting in make dist depending on the configuration.

Closes#10501
ZFS registers a memory hook, `__arc_shrinker_func`, which is supposed to
allow the ARC to shrink when the kernel experiences memory pressure.
The ARC shrinker changes `arc_c` via a call to
`arc_reduce_target_size()`. Before commit 3ec34e5527, the ARC
shrinker would also evict data from the ARC to bring `arc_size` down to
the new `arc_c`. However, that commit (seemingly inadvertently) made it
so that the ARC shrinker no longer evicts any data or waits for eviction
to complete.
Repeated calls to the ARC shrinker can reduce `arc_c` drastically, often
all the way to `arc_c_min`. Since it doesn't wait for the actual
eviction of data from the ARC, this creates a situation where `arc_size`
is more than `arc_c` for the several seconds/minutes it takes for
`arc_adjust_zthr` to evict data from the ARC. During this time,
arc_get_data_impl() will block, so ZFS can't process read/write requests
(e.g. from iSCSI, NFS, or read/write syscalls).
To ensure that `arc_c` doesn't shrink faster than the adjust thread can
keep up, this commit makes the ARC shrinker wait for the eviction to
complete, resulting in similar behavior to what we had before commit
3ec34e5527.
Note: commit 3ec34e5527 is `OpenZFS 9284 - arc_reclaim_thread
has 2 jobs` and was integrated in December 2018, and is part of ZoL
0.8.x but not 0.7.x.
Additionally, when the ARC size is reduced drastically, the
`arc_adjust_zthr` can be on-CPU for many seconds without blocking. Any
threads that are bound to the same CPU that arc_adjust_zthr is running
on will not able to run for a long time.
To ensure that CPU-bound threads can make progress, this commit changes
`arc_evict_state_impl()` make a voluntary preemption call,
`cond_resched()`.

This commit adds two features to zed, that macOS desires. The first
is that when you unload the kernel module, zed would enter into a
cpubusy loop calling zfs_events_next() repeatedly. We now look for
ENODEV, returned by kernel, so zed can exit gracefully.
Second feature is -I (idle) (alas -P persist was taken) is for the
deamon to;
1; if started without ZFS kernel module, stick around waiting for it.
2; if kernel module is unloaded, go back to 1.
This is due to daemons in macOS is started by launchctl, and is
expected to stick around.
Currently, the busy loop only exists when errno is ENODEV. This is
to ensure that functionality that upstream expects is not changed.
It did not care about errors before, and it still does not. (with the
exception of ENODEV).
However, it is probably better that all errors
(ERESTART notwithstanding) exits the loop, and the issues complaining
about zed taking all CPU will go away.

Implement semi-compatible functionality for mode=0 (preallocation)
and mode=FALLOC_FL_KEEP_SIZE (preallocation beyond EOF) for ZPL.
Since ZFS does COW and snapshots, preallocating blocks for a file
cannot guarantee that writes to the file will not run out of space.
Even if the first overwrite was guaranteed, it would not handle any
later overwrite of blocks due to COW, so strict compliance is futile.
Instead, make a best-effort check that at least enough free space is
currently available in the pool (with a bit of margin), then create
a sparse file of the requested size and continue on with life.
This does not handle all cases (e.g. several fallocate() calls before
writing into the files when the filesystem is nearly full), which
would require a more complex mechanism to be implemented, probably
based on a modified version of dmu_prealloc(), but is usable as-is.
A new module option zfs_fallocate_reserve_percent is used to control
the reserve margin for any single fallocate call. By default, this
is 110% of the requested preallocation size, so an additional 10% of
available space is reserved for overhead to allow the application a
good chance of finishing the write when the fallocate() succeeds.
If the heuristics of this basic fallocate implementation are not
desirable, the old non-functional behavior of returning EOPNOTSUPP
for calls can be restored by setting zfs_fallocate_reserve_percent=0.
The parameter of zfs_statvfs() is changed to take an inode instead
of a dentry, since no dentry is available in zfs_fallocate_common().
A few tests from @behlendorf cover basic fallocate functionality.

On Illumos callers of cv_timedwait and cv_timedwait_hires
can't distinguish between whether or not the cv was signaled
or the call timed out. Illumos handles this (for some definition
of handles) by calling cv_signal in the return path if we were
signaled but the return value indicates instead that we timed
out. This would make sense if it were possible to query the the
cv for its net signal disposition. However, this isn't possible
and, in spite of the fact that there are places in the code that
clearly take a different and incompatible path if a timeout value
is indicated, this distinction appears to be rather subtle to most
developers. This problem is further compounded by the fact that on
Linux, calling cv_signal in the return path wouldn't even do the
right thing unless there are other waiters.
Since it is possible for the caller to independently determine how
much time is remaining but it is not possible to query if the cv
was in fact signaled, prioritizing signalling over timeout seems
like a cleaner solution. In addition, judging from usage patterns
within the code itself, it is also less error prone.

For at least 15 years since OpenSolaris arc_c was set by default to
arc_c_max, later decreased under memory pressure. I've noticed that
if arc_c was set high enough to cause memory pressure as considered
by ZFS, setting of arc_no_grow to TRUE in arc_reap_cb_check() makes
no effect until both arc_kmem_reap_soon() and delay(reap_retry_ms)
return. All that time ZFS can continue increasing its effective ARC
size, causing more memory pressure, potentially up to the point when
OS low memory handler activates and reduces arc_c, requesting fast
reclamation of just allocated memory.
The problem seems to be more serious on FreeBSD and I guess Linux,
since neither of them implement/use asynchronous kmem reclamation,
so arc_kmem_reap_soon() can take more time. On older FreeBSD 11 not
supporting multiple memory domains system with lots of RAM can get
completely unresponsive for minutes due to heavy lock congestion
between ARC reclamation and page daemon kmem reclamation threads.
With this change to more conservative arc_c value ARC stops growing
just it time and does not need later reclamation.
Also while there, since now growing arc_c is a more often situation,
use aggsum_upper_bound() instead of aggsum_compare() in arc_adapt()
to reduce lock congestion. It is also getting in sync with code in
arc_get_data_impl().

For MIPS architectures on Linux the ZERO_PAGE macro references
empty_zero_page, which is exported as a GPL symbol. The call to
ZERO_PAGE in abd_alloc_zero_scatter has been removed and a single
zero'd page is now allocated for each of the pages in abd_zero_scatter
in the kernel ABD code path.

There a some attributes missing which are shown in man pages:
zfs list -t type
A comma-separated list of types to display, where type is one of filesystem, snapshot, volume, *bookmark*, or all. For example, specifying -t snapshot displays only snapshots.
zfs get -s source
A comma-separated list of sources to display. Those properties coming from a source other than those in this list are ignored. Each source must be one of the following: local, default, inherited, temporary, *received*, and none. The default value is all sources.

The horrible effects of human slavery continue to impact society. The
casual use of the term "slave" in computer software is an unnecessary
reference to a painful human experience.
This commit removes all possible references to the term "slave".
Implementation notes:
The zpool.d/slaves script is renamed to dm-deps, which uses the same
terminology as `dmsetup deps`.
References to the `/sys/class/block/$dev/slaves` directory remain. This
directory name is determined by the Linux kernel. Although
`dmsetup deps` provides the same information, it unfortunately requires
elevated privileges, whereas the `/sys/...` directory is world-readable.
