fix GCC 5.0.0 logical-not-parentheses warnings
man gcc:
Warn about logical not used on the left hand side operand of a
comparison. This option does not warn if the RHS operand is of a
boolean type.
By preferring bool over int where sensible, but without modifying any
depending code, make GCC happy in cases like this,
qemu-img.c: In function ‘compare_sectors’:
qemu-img.c:992:39: error: logical not is only applied to the left hand
side of comparison [-Werror=logical-not-parentheses]
if (!!memcmp(buf1, buf2, 512) != res) {
hw/ide/core.c:1836 doesn't throw an error,
assert(!!s->error == !!(s->status & ERR_STAT));
even thought the second operand is int (and first hunk of this patch has
a very similar case), maybe GCC developers still have a little faith in
C programmers.
