Porting notes:
- The library libdiskmgmt is specific to illumos so these changes
currently have no impact under Linux. This mechanism could be
potentially leveraged in the future.
Use -pH flags in get_pool_prop so that numeric properties such as size
can be compared. The zpool_expand test suite is currently the only one
which uses get_pool_prop for a numeric property.
Add TEMPFILE and TEMPFILE{0,1,2} to default.cfg for tests that must
build pools on top of files, such as this one where expansion is
necessary but the entries in DISKS may not point to entities that can be
expanded.
Base the pool used for testing on file-type VDEVs instead of using zvols
within an underlying pool, to avoid issues that come up when pools are
backed by other pools.
Remove shell variables EX_1GB and EX_2GB used to recognize correct expansion,
and instead calculate the appropriate values based on the variables used to
control file or volume size, org_size and exp_size. This change is also
made in test 001 although that test is not enabled because it depends on
FMA.
Finally, enable zpool_expand_002_pos.

This is a race condition in the deadlist code.
A thread executing an administrative command that uses
dsl_deadlist_space_range() holds the lock of the whole deadlist_t to
protect the access of all its entries that the deadlist contains in an
avl tree.
Sync threads trying to insert a new entry in the deadlist (through
dsl_deadlist_insert() -> dle_enqueue()) do not hold the deadlist lock at
that moment. If the dle_bpobj is the empty bpobj (our sentinel value),
we close and reopen it. Between these two operations, it is possible
for the dsl_deadlist_space_range() thread to dereference that bpobj
which is NULL during that window.
Threads should hold the a deadlist's dl_lock when they manipulate its
internal data so scenarios like the one above are avoided.

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.
This change avoids the issue by explicitly setting the cwd to
a different path when performing the mount.

- libzfs_sendrecv.c: SMALLEST_POSSIBLE_MAX_DDT_MB is always used

Commit 539d33c seems to have significantly increased the run time
of the sparse_001_pos.ksh and truncate_001_pos.ksh test cases on
32-bit systems. This is likely due to dirty blocks from frees
being deferred to later txgs.
At the moment this is resulting in frequent failures on the

analyzed and resolved.

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.
