ICU: check for U_STRING_NOT_TERMINATED_WARNING.

Fixes memory error in cases where the length of the language name
returned by uloc_getLanguage() is exactly ULOC_LANG_CAPACITY, in which
case the status is set to U_STRING_NOT_TERMINATED_WARNING.

Also check in call sites for other ICU functions that are expected to
return a C string to be safe (no bug is known at these other call
sites).
