Fix ICU glue for uloc_toLanguageTag.
There were several issues :
- ICU does not set the output param UErrorCode* to U_ZERO_ERROR
when an API call is successful, so we need to clear it before every
API call.
- ICU sets the error code to U_BUFFER_OVERFLOW_ERROR (and sets the
output length to the required size) if the input buffer is too
small.
- ICU sets the error code to U_STRING_NOT_TERMINATED_WARNING when
the input buffer is one character too short.
