There are two cases where changing canmount should result in an action:
- canmount is set to off for a mounted filesystem
- canmount is set to on for an unmounted filesystem
Before r297521 we could unmount and re-mount a filesystem when that was
not necessary, but after r297521 we only handled the first of the above
cases.

Add syntactic sugar to dtrace: "if" and "else" statements. The sugar is
baked down to standard dtrace features by adding additional clauses with
the appropriate predicates.

When using zdb with non-default SPA config file it is not convenient
to add -U <non-default-config-file-path> all the time. This commit
introduces support for setting/overriding SPA config location via
environment variable 'SPA_CONFIG_PATH'.
If -U flag is specified in the command line it will override any other
value as usual.

At the moment type parameter of lzc_create() is of dmu_objset_type_t type.
That exposes an implementation detail and requires sys/fs/zfs.h to be included
in libzfs_core.h creating unnecessary coupling between libzfs_core interface
and ZFS internals.
I think that dmu_objset_type_t should be replaced with a libzfs_core
enumeration of supported dataset types.
For ABI reasons the new enumeration could be bit-compatible with
dmu_objset_type_t.
For example:
typedef enum {
LZC_DST_ZFS = 2,
LZC_DST_ZVOL
} lzc_dataset_type_t;

This allows one to enable DTrace probes relatively early during boot,
during SI_SUB_DTRACE_ANON, before dtrace(1) can invoked. The desired
enabling is created using dtrace -A, which writes a /boot/dtrace.dof
file and uses nextboot(8) to ensure that DTrace kernel modules are loaded
and that the DOF file describing the enabling is loaded by loader(8)
during the subsequent boot. The trace output can then be fetched with
dtrace -a.
With this commit, boot-time DTrace is only functional on i386 and amd64: on
other architectures, the high-resolution timer frequency is initialized
during SI_SUB_CLOCKS and is thus not available when the anonymous
tracing state is initialized. On x86, the TSC is used and is thus available
earlier.

Currently, zfs(8) and zpool(8) print "invalid type '(null)'" or similar
messages, if you pass in invalid types, sources or column names for "zfs
get", "zfs list" and "zpool get". This is because the commands use
getsubopt(3), and in case of failure, they print 'value', which is NULL
when sub options don't match.
They should print 'suboptarg' instead, which is the documented way to
get at the non-matching sub option value.

This allows to do a full (non-incremental send) and receive it as a clone
of an existing dataset. It can leverage nopwrite to share blocks with the
origin. This can be used to change the relationship of datasets on the
target. For example, maybe on the source you have:
A ---- B ---- C
And you have sent to the target a full of B, and the incremental B->C:
B ---- C
You later realize that you want to have A on the target. You will have to
do a full send of A, but nopwrite can save you space on the target if you
receive it as a clone of B, assuming that A and B have some blocks inxi
common:
B ---- C

r281257 added support for lazyload mode by allowing dtrace(1) to register
a DOF section on behalf of a traced process. This was implemented by
having libdtrace copy the DOF section into a heap-allocated buffer and
passing its address to the ioctl handler. However, DTrace uses the DOF
section address as a lookup key in certain cases, so the ioctl handler
should be given the target process' DOF section address instead. This
change modifies the ADDDOF handler to copy the DOF section in from the
target process, rather than from dtrace(1).
Fix zfs(8) not formatting due to wrong macro (Oc) in the syntax for the new
zfs set multiple dataset properties option.
