XXX double check PUT_LINK_COOKIE and GET_LINK_COOKIE, maybe should have
been fixed up earlier

This adds zfs_valstr, a collection of pretty printers for bitfields and
enums. These are useful in debugging, logging and other display contexts
where raw values are difficult for the untrained (or even trained!) eye
to decipher.

Requires the new 'flat' physical data which has the start
time for a class entry.
The amount to prune can be based on a target percentage of
the unique entries or based on the age (i.e., every entry
older than N days).

The simplest thing first: add the FDT and log objects to the list of
objects to be considered when checking for leaks.
The rest is based on a conceptual change in all of this patch stack: a
block on disk with a 'D' bit is not necessarily in the DDT at all
(pruned), or in the DDT ZAPs (still on the log).
As such, walking the DDT up front is difficult (for all the reasons that
walking an unflushed log is difficult) and not really useful, since it's
not a reflection of what's on disk anyway.
Instead, we rework things here to be more like the BRT checks. When we
see a dedup'd block, we look it up in the DDT, consume a refcount, and
for the second-or-later instances, count them as duplicates.

Closes#16277
In 4938d01db (#14086) zio_flag_t was converted from an enum (generally
signed 32-bit) to a uint64_t. The corresponding change wasn't made to
the error reporting subsystem, limiting the error flags being delivered
to zed to 32 bits. This bumps the whole pipeline to use uint64s.
A tiny bit of compatibility is added for newer zed working agsinst an
older kernel module, because its easy to do and misdetecting
scrub/resilver errors and taking action is potentially dangerous. Making
it work for new kernel modules against older zed seems to be far more
invasive for far less benefit, so I have not.

When process got SIGSTOP/SIGTSTP, issig() dequeue them and return 0.
But process could still have another signal pending after dequeue. So,
after dequeue, check and return 1, if signal_pending.

This commit extends the zpool-reguid(8) command with a -g flag, which
allows the user to specify the GUID to set.
This change also adds some general tests for zpool-reguid(8).
