Remove "dbuf phys" db->db_data pointer aliases.
Use function accessors that cast db->db_data to the appropriate
"phys" type, removing the need for clients of the dmu buf user
API to keep properly typed pointer aliases to db->db_data in order
to conveniently access their data.

In zap_leaf() and zap_leaf_byteswap, now that the pointer alias
field l_phys has been removed, use the db_data field in an on
stack dmu_buf_t to point to the leaf's phys data.

Reduce scrub activities when system there is enough dirty data, namely when
dirty data is more than zfs_vdev_async_write_active_min_dirty_percent (once

Use calloc() instead of malloc() + bzero(). This also gets rid of a warning
because bzero is defined by strings.h which is not included in thread_pool.c.
When importing a pool, don't assume that the passed pool configuration
at vdev_load is always vaild. It's possible that a stale configuration
that comes with extra vdevs, where metaslab_init() would fail because
of lower layer returns error.
Change the code to make metaslab_init() handle and return errors from
lower layer and pass it back to upper layer and handle it there.

Add FPU support for MIPS setjmp(3)/longjmp(3).
This change saves/restores the callee-saved MIPS floating point
registers as documented by the o32/n32/n64 spec ("MIPSpro N32
ABI Handbook", Table 2-1) for the _setjmp(3), _longjmp(3),
setjmp(3) and longjmp(3) C library functions. This is only
included when the C library is built with hardware floating point
support (or when "SOFTFLOAT" is not defined).

Fix building/installing tests when TESTSBASE != /usr/tests
The work in r258233 hardcoded the assumption that tests was the last component
of the tests tree by pushing tests as an explicit prefix for the paths in
BSD.tests.dist and /usr was the prefix for all tests, per BSD.usr.dist and all
of the mtree calls used in Makefile.inc1. This assumption breaks if/when one
provides a custom TESTSBASE "prefix", e.g. TESTSBASE=/mytests .
One thing that r258233 did properly though was remove "/usr/tests" creation
from BSD.usr.dist -- that should have not been there in the first place. That
was an "oops" on my part for the work that was originally committed in r241823
