rstoyanchev e12f0761f3 Refactor maxInMemory limit handling for async XML parsing
The limit was previously enforced in XmlEventDecoder, because it is
what parses incoming buffers. However, the actual caching is in
Jaxb2Decoder, which holds on to XML events, but has no good way to
estimate their size.

After this commit XmlEventDecoder no longer enforces memory limits
for async parsing. It releases each buffer immediately anyway.

Instead XmlEventDecoder is only responsible to update the number
of bytes received via a new ReceivedByteTracker type while
Jaxb2XmlDecoder uses the same to perform limit and reset the
count depending on when it is aggregating XML events.
