We store anonymized values as pointers to "const char *", since they are
conceptually const to callers who use them. But they are actually
allocated strings whose memory is owned by the struct.

The ownership mismatch hasn't been a big deal since we never free() them
(they are held until the program ends), but let's switch them to "char *"
in preparation for changing that.

Since most code only accesses them via anonymize_str(), it can continue
to narrow them to "const char *" in its return value.
