man gcc:
  Warn if in a loop with constant number of iterations the compiler
  detects undefined behavior in some statement during one or more of
  the iterations.

Milkymist pfpu has no jump instructions, so checking for MICROCODE_WORDS
instructions should have kept us in bounds of s->microcode, but i++
allowed one loop too many,

  hw/misc/milkymist-pfpu.c: In function ‘pfpu_write’:
  hw/misc/milkymist-pfpu.c:365:20: error: loop exit may only be reached after undefined behavior [-Werror=aggressive-loop-optimizations]
                   if (i++ >= MICROCODE_WORDS) {
                      ^
  hw/misc/milkymist-pfpu.c:167:14: note: possible undefined statement is here
       uint32_t insn = s->microcode[pc];
                ^

The code can still access out of bounds, because it presumes that PC register
always begins at 0, and we allow writing to it.

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.

numero sign is the number sign key of Russian keyboard layout, we
get this key with 'shift + 3'. It's missing in current Russian keymap file,
this patch fixes it.
As number sign does not exsit in Russian keyboard layout[1][2], this
patch also removes the 'numbersign' from Russian keymap.
