When building QEMU for NetBSD ("make vm-build-netbsd"), the compiler
complains:
In file included from /usr/include/ctype.h:100,
from ../src/include/qemu/osdep.h:123,
from ../src/util/cutils.c:25:
../src/util/cutils.c: In function 'do_strtosz':

245 | if (retval == 0 && *endptr == '.' && !isdigit(endptr[1])) {
isdigit() should not be used with plain "char" variables since these
can be signed and isdigit() could be implemented as a macro that uses
its parameter to index into an array. Use our wrapper qemu_isdigit()
to fix this problem.
