description:
lint: rename val_t.v_ansiu to v_unsigned
When lint was written in 1995, traditional C was still nearby since C90
had been around for only 5 years. 26 years later, almost all code
adheres to C90 or even C99 or C11, therefore "C90 or later" can safely
be assumed as the default.
No functional change.
