Don't check for overlapping in strncpy/stpncpy for now2023-12-27T15:06:59Zjvoisin2023-12-27T11:36:47Zurn:sha1:80a83a56b52e833e6d3afec4d0723d7625d52cee
They check overlap across the whole range of the given length, but
the given length is not what will actually be copied, rather it's
the maximum length (if src is shorter, only length of src will be
copied). This triggers false positives and traps where it shouldn't
(e.g. in ICU tests).
