In an image chain, if the base image is smaller than the current
image, we need to make sure to use the current images count of
unallocated blocks once we get to the end of the base image. Without
this change the code will return 0 blocks when it gets to the end
of the base image and mirror_run will fail its assertion.

Since commit 65dee38052 (target-i386:
move cpu_reset and reset callback to cpu.c) the x86 CPU is reset through
cpu_init() but was still reset immediately after in linux-user and
bsd-user. Clean this up.
Similarly in linux-user/syscall.c it is also reset after cpu_copy().
But that's a bug of its own, fixing which poses a semantic change.

Sign-extend the result of LWR, as is already done for LWL. This is necessary
in the case where LWR loads the full word (i.e. the address is actually
aligned). In the other cases, it is implementation defined whether the
upper 32 bits of the result are unchanged or a copy of bit 31. The latter
seems easier to implement.
Previously the code used:
(oldval & (0xfffffffe << (31 - bitshift))) | (newval >> bitshift)
which zeroed the upper bits of the register, losing any previous sign
extension in the unaligned cases.
