Unlike iconv or the internal converters, ICU consumes truncated multi- byte sequences at the end of an input buffer. We currently check for a non-empty raw input buffer to detect truncated sequences, so this fails with ICU. It might be possible to inspect the pivot buffer pointers, but it seems cleaner to implement a `flush` flag for some encoding and I/O functions. After flushing, we can check for U_TRUNCATED_CHAR_FOUND with ICU, or detect remaining input with other converters. Also fix detection of truncated sequences for HTML, XML content and DTDs with iconv.
