Close a race involving the OEA64 scratchpage. When the scratch page's

the page table lock, it was possible for another CPU to insert a new PTE
into the scratch page's PTEG slot during this interval, corrupting both
mappings.
Solve this by creating a new flag, LPTE_LOCKED, such that
moea64_pte_insert will avoid claiming locked PTEG slots even if they
are invalid. This change also incorporates some additional paranoia
added to solve things I thought might be this bug.

When growing a UFS1 filesystem, we need to initialise all inodes in any new
cylinder groups that are created. When the filesystem is first created,
newfs always initialises the first two blocks of inodes, and then in the
UFS1 case will also initialise the remaining inode blocks. The changes in
growfs.c 1.23 broke the initialisation of all inodes, seemingly based on
this implementation detail in newfs(8). The result was that instead of
initialising all inodes, we would actually end up initialising all but the
first two blocks of inodes. If the filesystem was grown into empty
(all-zeros) space then the resulting filesystem was fine, however when
grown onto non-zeroed space the filesystem produced would appear to have
massive corruption on the first fsck after growing.
A test case for this problem can be found in the PR audit trail.
Fix this by once again initialising all inodes in the UFS1 case.

- The OPSZ macro actually only does the right thing for int32 and int64
operands but not for double and extended double ones. Instead of trying
to fix the macro just nuke it and unroll the loops in the correct way
though as extended double operands turn out to be the only special case.
- For FxTO{s,d,q} the source operand is int64 so rs2 has to be re-decoded
after setting type accordingly as it's generally decoded using the low
2 bits as the type, which are 0 for these three instructions.
- Similarly, in case of F{s,d,q}TOx the target is int64 so rd has to be
re-decoded using not only the operand mask appropriate for int64 but
also the correct register number encoding.
- Use const where appropriate.

This approach would have two problems. First, we are not guaranteed to
be waken up at the beginning of a whole second, which will typically
exhibit as a "lag" on second number. Second, because we sleep for whole
second, and the refresh process would take some time, the error would
accumulate from time to time, making the lag variable.
Make grdc(6) to use time(3) to get time only at the beginning, and sample
time in CLOCK_REALTIME_FAST granularity after refreshing, and use the
nanosecond part to caculate how much time we want to sleep.
