Commit d759c951f3 ("replay: push
replay_mutex_lock up the call tree") removed the !timeout lock
optimization in the main loop.
The idea of the optimization was to avoid ping-pongs between threads by
keeping the Big QEMU Lock held across non-blocking (!timeout) main loop
iterations.
A warning is printed when the main loop spins without releasing BQL for
long periods of time. These warnings were supposed to aid debugging but
in practice they just alarm users. They are considered noise because
the cause of spinning is not shown and is hard to find.
Now that the lock optimization has been removed, there is no danger of
hogging the BQL. Drop the spin counter and the infamous warning.

We don't verify the request range against s->size in the I/O callbacks
except for raw_co_pwritev. This is inconsistent (especially for
raw_co_pwrite_zeroes and raw_co_pdiscard), so fix them, in the meanwhile
make the helper reusable by the coming new callbacks.
Note that in most cases the block layer already verifies the request
byte range against our reported image length, before invoking the driver
callbacks. The exception is during image creating, after
blk_set_allow_write_beyond_eof(blk, true) is called. But in that case,
the requests are not directly from the user or guest. So there is no
visible behavior change in adding the check code.
The int64_t -> uint64_t inconsistency, as shown by the type casting, is
pre-existing due to the interface.

This patch fixes a bug in serial that made it almost impossible for guest
to communicate with devices through host's serial.
OPOST flag in c_oflag enables output processing letting other flags in
c_oflag take effect. Usually in c_oflag ONLCR flag is also set, which
causes crlf to be sent in place of lf. This breaks binary transmissions.
Unsetting OPOST flag turns off any output processing which fixes the bug.

instead create a kcs structure separate and use that.
There were also some issues in the state transfer. The inlen field
was not being transferred, so if a transaction was in process during
the transfer it would be messed up. And the use_irq field was
transferred, but that should come from the configuration.
To fix this, the new VMS_VSTRUCT macros are used so the exact
version of the structure can be specified, depending on what
version was being received. So an upgrade should work for KCS.
