Reorder arguments to be more natural, readable and
consistent with other iov_* functions, and change
argument names, from:
iov_from_buf(iov, iov_cnt, buf, iov_off, size)
to
iov_from_buf(iov, iov_cnt, offset, buf, bytes)
The result becomes natural English:
copy data to this `iov' vector with `iov_cnt'
elements starting at byte offset `offset'
from memory buffer `buf', processing `bytes'
bytes max.
(Try to read the original prototype this way).
Also change iov_clear() to more general iov_memset()
(it uses memset() internally anyway).
While at it, add comments to the header file
describing what the routines actually does.
The patch only renames argumens in the header, but
keeps old names in the implementation. The next
patch will touch actual code to match.
Now, it might look wrong to pay so much attention
to so small things. But we've so many badly designed
interfaces already so the whole thing becomes rather
confusing or error prone. One example of this is
previous commit and small discussion which emerged
from it, with an outcome that the utility functions
like these aren't well-understdandable, leading to
strange usage cases. That's why I paid quite some
attention to this set of functions and a few
others in subsequent patches.

Original code has one thing to process (cur_len), requests to
convert from iovec to buf another thing (len which is actually max_len),
and processes something else (copied). Whole thing is very difficult
to understand, even if it does a right thing. The iov_to_buf()
conversion in this case will always return cur_len, because it is
the length of the iovec it was asked to process, and the size we
asked to convert is the same or larger, and iov_to_buf() will stop
at reaching either iov or buf.
Make the code saner by doing the only sane thing: dropping `copied'
which is always the same as `cur_len' but just introduces questions.

In commit 1bba0dc932e8826a7d030df3767daf0bc339f9a2 cpu_reset()
was renamed to cpu_state_reset(), to allow introducing a new cpu_reset()
that would operate on QOM objects.
All callers have been updated except for one in target-mips, so drop all
implementations except for the one in target-mips and move the
declaration there until MIPSCPU reset can be fully QOM'ified.

Commit 0f71a7095db6bc055bc5bb520d85ea650cca8a33 (target-mips: QOM'ify
CPU) hooked up cpu_state_reset() to CPUClass::reset(). Dropping the
introduction of subclasses for 1.1, due to mips_def_t the reset code
could not be QOM'ified yet, i.e. cpu_state_reset() will not forward to
CPUClass::reset().
Update cpu_mips_init() with cpu_reset() nontheless, indirectly calling
cpu_state_reset(), so that generic code can be converted to call
cpu_reset().
