target-ppc/translate.c puts values of type opcode_t into .opcodes
section, using GCC extension to do so, and hoping that this will make
them appear contiguously and in the source order in the resulting
executable. This assumption is not safe and is known to be violated
with certain versions of GCC, certain flags passed to it and on
certain platforms (gcc 4.3.0, -O and PPC/PPC64 for instance)
The workaround consists of adding -fno-unit-at-a-time to the list of
GCC command line options while building PPC translate.o on a PPC.

AFAIK, it's never been enabled and hasn't even compiled in ages. Remove the
code to avoid confusion. If someone ever decides to fix it, they can get at
the old version in RCS history.

Recent patches added two compiler warnings about the format string
usage in qcow_read_extensions. One is printing a uint64_t using
%lu which is incorrect on many platforms as it can be a unsigned
long long, the second one is printing the result of sizeof as
%lu, but it is a size_t so it needs to be printed using %zu.

All the bdrv_ helpers should check for bs->drv being zero as that means
there is no backend image open. bdrv_flush fails to perform that check
and can thus cause NULL pointer dereferences.

Remove code dealing with negative sector numbers for byte access in
bdrv_check_request as sector numbers can't ever be negative.
Previously we supported negative sector counts for byte access, but
never sector numbers.

While searching PC, always store the pc of a new instruction.
Instructions that didn't generate tcg code (such as nop) prevented the
next one to be referenced.
