This will make it possible to skip mixeng with audio playback and
recording, allowing us to free ourselves from the limitations of the
current mixeng (stereo, int64 samples only). In this case, HW and SW
voices will be essentially the same, for every SW voice we will create
a HW voice, since we can no longer mix multiple voices together.
Some backends expect us to call a function when we have data ready
write()/read() style, while others provide a buffer and expects us to
directly write/read it, so for optimal performance audio_pcm_ops provide
methods for both cases. Previously backends asked mixeng for more data
in run_out/run_it, now instead mixeng or the frontends will call the
backends, so that's why two sets of functions required. audio.c
contains glue code between the two styles, so backends only ever have to
implement one style and frontends are free to call whichever is more
convenient for them.

As we are moving between address spaces, we can use access_memmove()
without checking for destructive overlaps (especially of real storage
locations):
"Each storage operand is processed left to right. The
storage-operand-consistency rules are the same as
for MOVE (MVC), except that when the operands
overlap in real storage, the use of the common real-
storage locations is not necessarily recognized."

Replace fast_memmove() variants by access_memmove() variants, that
first try to probe access to all affected pages (maximum is two pages).
Introduce access_get_byte()/access_set_byte(). We might be able to speed
up memmove in special cases even further (do single-byte access, use
memmove() for remaining bytes in page), however, we'll skip that for now.
In MVCOS, simply always call access_memmove_as() and drop the TODO
about LAP. LAP is already handled in the MMU.
Get rid of adj_len_to_page(), which is now unused.

Process max 4k bytes at a time, writing back registers between the
accesses. The instruction is interruptible.
"For operands longer than 2K bytes, access exceptions are not
recognized for locations more than 2K bytes beyond the current location
being processed."
Note that on z/Architecture, 2k vs. 4k access cannot get differentiated as
long as pages are not crossed. This seems to be a leftover from ESA/390.
Simply stay within single pages.
MVCL handling is quite different than MVCLE/MVCLU handling, so split up
