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).

This commit changes the frontend zio_compress_data and
zio_decompress_data APIs to take ABD points instead of buffer pointers.
All callers are updated to match. Any that already have an appropriate
ABD nearby now use it directly, while at the rest we create an one.
Internally, the ABDs are passed through to the provider directly.

This commit changes the provider compress and decompress API to take ABD
pointers instead of buffer pointers for both data source and
destination. It then updates all providers to match.
This doesn't actually change the providers to do chunked compression,
just changes the API to allow such an update in the future. Helper
macros are added to easily adapt the ABD functions to their buffer-based
implementations.

This allows a simple "wrapping" ABD for an existing linear buffer to be
allocated on the stack, avoiding an allocation.

Removing the platform #ifdefs from shared headers in favour of
per-platform headers. Makes abd_t much leaner, among other things.

The Linux abd_os.c serves double-duty as the userspace scatter abd
implementation, by carrying an emulation of kernel scatterlists. This
commit lifts common and userspace-specific parts out into a separate
abd_os.c for libzpool.
