This code has an optimised, word aligned version, and a boring
unaligned version. My commit f70d345 fixed one alignment issue, but
there's another.
The optimised version operates on 'longs' dealing with (typically) 64
pages at a time, replacing the whole long by a 0 and counting the bits.
If the Ramblock is less than 64bits in length that long can contain bits
representing two different RAMBlocks, but the code will update the
bmap belinging to the 1st RAMBlock only while having updated the total
dirty page count for both.
This probably didn't matter prior to 6b6712ef which split the dirty
bitmap by RAMBlock, but now they're separate RAMBlocks we end up
with a count that doesn't match the state in the bitmaps.
Symptom:
Migration showing a few dirty pages left to be sent constantly

Use of a loop construct for code that is not intended to repeat
does not make much idiomatic sense, except in one place: it is a
common usage in macros in order to wrap arbitrary code with
single-statement semantics. But when used in a macro, it is more
typical for the caller to supply the trailing ';' when calling
the macro.
Although qemu coding style frowns on bare:
if (cond)
statement1;
else
statement2;
where extra semicolons actually cause syntax errors, we still
want our macro styles to be easily copied to other projects.
Thus, declare it an error if we encounter any form of 'while (0)'
with a semicolon in the same line.

The point of writing a macro embedded in a 'do { ... } while (0)'
loop (particularly if the macro has multiple statements or would
otherwise end with an 'if' statement) is so that the macro can be
used as a drop-in statement with the caller supplying the
trailing ';'. Although our coding style frowns on brace-less 'if':
if (cond)
statement;
else
something else;
that is the classic case where failure to use do/while(0) wrapping
would cause the 'else' to pair with any embedded 'if' in the macro
rather than the intended outer 'if'. But conversely, if the macro
includes an embedded ';', then the same brace-less coding style
would now have two statements, making the 'else' a syntax error
rather than pairing with the outer 'if'. Thus, even though our
coding style with required braces is not impacted, ending a macro
with ';' makes our code harder to port to projects that use
brace-less styles.
The change should have no semantic impact. I was not able to
fully compile-test all of the changes (as some of them are
examples of the ugly bit-rotting debug print statements that are
completely elided by default, and I didn't want to recompile
with the necessary -D witnesses - cleaning those up is left as a
bite-sized task for another day); I did, however, audit that for
all files touched, all callers of the changed macros DID supply
a trailing ';' at the callsite, and did not appear to be used
as part of a brace-less conditional.
Found mechanically via: $ git grep -B1 'while (0);' | grep -A1 \\\\

Use of a do/while(0) loop as a way to allow break statements in
the middle of execute-once code is unusual. More typical is
the use of goto for early exits, with a label at the end of
the execute-once code, rather than nesting code in a scope;
however, the comment at the end of the existing code makes this
alternative a bit unpractical.
So, to avoid false positives from a future syntax check about
'while (false);', and to keep the loop form (in case someone
ever does add DONTWAIT support, where they can just as easily
manipulate the initial loop condition or add an if around the
final 'break'), I opted to use the form of a while(1) loop (the
break as an early exit is more idiomatic there), coupled with
a final break preserving the original comment.

Except for round-robin TCG, every other accelerator is using more or
less the same code around qemu_wait_io_event_common. The exception
is HAX, which also has to eat the dummy APC that is queued by
qemu_cpu_kick_thread.
We can add the SleepEx call to qemu_wait_io_event under "if
(!tcg_enabled())", since that is the condition that is used in
qemu_cpu_kick_thread, and unify the function for KVM, HAX, HVF and
multi-threaded TCG. Single-threaded TCG code can also be simplified
since it is only used in the round-robin, sleep-if-all-CPUs-idle case.
