In tools/ directory, function bitmap_clear() is currently only used in
object file tools/testing/radix-tree/xarray.o.
But instead of keeping a bitmap.c with only bitmap_clear() definition in
radix-tree's own directory, it would be more proper to put it in common
directory lib/.
Sync the kernel definition and link some related libs, no functional
change is expected.

bitmap_weight() doesn't return negative values, so change it's type
to unsigned long. It may help compiler to generate better code and
catch bugs.

Some bitmap functions return boolean results in int variables. Fix it
by changing return types to bool.
Signed-off-by: Yury Norov <yury.norov@gmail.com>
Both nodemask and bitmap routines had mixed return values that provided
potentially signed return values that could never happen. This was
leading to the compiler getting confusing about the range of possible
return values (it was thinking things could be negative where they could
not be). In preparation for fixing nodemask, fix all the bitmap routines
that should be returning unsigned (or bool) values.

Extend tools bitmap API with bitmap_equal() implementation.
The implementation has been derived from the kernel.
Extend tools bitmap API with bitmap_free() implementation for symmetry
with bitmap_alloc() function.
