Reduce stack by inlining spa_impl_load
...
The spa_load function may call itself recursively through
the spa_load_impl function. This call path of spa_load->
spa_load_impl->spa_load->spa_load_impl takes 640 bytes of
stack. By forcing spa_load_impl to be inlined as part of
spa_load the can be reduced to 448 bytes, for a savings of
192 bytes,

Move ztest_od_t structures to the heap
...
A number of ztest functions create one or more 312B ztest_od_t data
structures. To conserve stack usage, this commit moves all of these data
structures to the heap. However, I am still seeing ztest segfaults due
to heavy stack usage of the dbuf_findbp() -> dbuf_hold_impl() recursion.

Remove declarations in VERIFY3_IMPL to save stack
...
This has a minor impact on stack usage of individual functions, but the
VERIFY macros are used so frequently that their overhead may add up.
This macro declared two new local variables to cast its argument types.
Doing the typecast inline eliminates the need for these variables.

Use sparse files for loopback+file configurations
...
Using sparse files for the test configurations had atleast three
significant advantages.
1) Actually test sparse files to ensure they work.
2) Drastically reduce required disk space for the regression test
suite. This turns out to be fairly important when running the
test suite in a virtualized environment.
3) Significantly speed of the test suite. Run time of zconfig.sh
dropped from 2m:56s to 1m:00s on my test system, zpios-sanity.sh
nows runs in only 0m:26s.

Update zconfig.sh
...
This change updates zconfig.sh to reference /dev/zvol/ instead
of simply /dev/. It also extends the texts to verify correct
minor device creation for import/export and module load/unload.
