Such items may be allocated in the I/O path used by the dumper,
potentially causing the dump to fail. Since there is some precedent
in the DMAR driver for avoiding this problem using _NODUMP, apply
this workaround to the zone as well.

zdb(8) is full of minor problems that generate compiler warnings. On FreeBSD,
which uses -WError, the only way to build it is to disable all compiler
warnings. This makes it much harder to detect newly introduced bugs. We should
cleanup all the warnings.

This adds sys/modules/imx with a SUBDIR makefile to make the whole
collection of modules that are specific to these SoCs. Initially, that
"whole collection" consists of the if_ffec and imx_i2c drivers.
The if_ffec driver is referenced in its existing home in ../ffec rather
than moving it into the imx directory, because it's used by powerpc too,
but it is no longer built for all armv6/7 systems.
The imx_i2c driver is newly added as a module.
8502 illumos#7955 broke delegated datasets when libshare is not present
illumos/illumos-gate@1c18e8fbd81c18e8fbd8https://www.illumos.org/issues/8502
The code in lib/libzfs/common/libzfs_mount.c already basically handles
the case when libshare is not installed. We just need to not fail in
zfs_init_libshare_impl. I tested this in lx and things work as
expected. I also tested there trying to set sharenfs and sharesmb on
the delegated dataset. Neither is allowed from within a zone. The
spew of msgs from a native zone is not ZFS specific. I see the same
spew simply running the share command.

Some other points I think we need to be consistent on:
- Spacing around string concatenation (always)
- Test against 'nil' explicitly rather than relying on 'not' for things that
reasonably won't be returning a boolean. e.g. loader.getenv
Eventually this will all get formalized somewhere.
illumos/illumos-gate@5cabbc6b49https://www.illumos.org/issues/7614:
This project allows top-level vdevs to be removed from the storage pool with
“zpool remove”, reducing the total amount of storage in the pool. This
operation copies all allocated regions of the device to be removed onto other
devices, recording the mapping from old to new location. After the removal is
complete, read and free operations to the removed (now “indirect”) vdev must
be remapped and performed at the new location on disk. The indirect mapping
table is kept in memory whenever the pool is loaded, so there is minimal
performance overhead when doing operations on the indirect vdev.
The size of the in-memory mapping table will be reduced when its entries
become “obsolete” because they are no longer used by any block pointers in
the pool. An entry becomes obsolete when all the blocks that use it are
freed. An entry can also become obsolete when all the snapshots that
reference it are deleted, and the block pointers that reference it have been
“remapped” in all filesystems/zvols (and clones). Whenever an indirect block
is written, all the block pointers in it will be “remapped” to their new
(concrete) locations if possible. This process can be accelerated by using
the “zfs remap” command to proactively rewrite all indirect blocks that
reference indirect (removed) vdevs.
Note that when a device is removed, we do not verify the checksum of the data
that is copied. This makes the process much faster, but if it were used on
redundant vdevs (i.e. mirror or raidz vdevs), it would be possible to copy
the wrong data, when we have the correct data on e.g. the other side of the
mirror. Therefore, mirror and raidz devices can not be removed.

Once we've successfully loaded a kernel, we add its directory to
module_path. If we switch kernels with the kernel selector, we again prepend
the kernel directory to the current module_path and end up with multiple
kernel paths, potentially with mismatched kernel/modules, added to
module_path.
Fix it by caching module_path at load() time and using the cached version
whenever we load a new kernel.

I guess this can only happen when imx_ehci_detach() is called on the
error-exit path from imx_ehci_attach(), and that path never got exercised
before today.
In a similar fashion to FILE, provide thin shims for the standard directory
manipulation functions.
