InputStream should be allowed to return 0 bytes read

See original GitHub issue

_loadMore() should handle read() returning 0 bytes here https://github.com/FasterXML/jackson-core/blob/master/src/main/java/com/fasterxml/jackson/core/json/UTF8StreamJsonParser.java#L193

read() method doesn’t guarantee a non-zero number of bytes are read https://docs.oracle.com/javase/7/docs/api/java/io/InputStream.html#read(byte[], int, int)

@jbalint Thank you for following up with Undertow if it returns 0 even if buffer would have space. That does not sound like correct behavior, given practical difficults in taking other actions.
