Position parser at START_ELEMENT before parsing
This PR aims to provide parseXrdLinkReferencesFor() method the ability
to parse forward to the first START_ELEMENT tag.The HttpLookupMethodTest
tests the HttpLookupMethod class by parsing String. This makes use of
PacketParserUtils.getParserFor(String), which already does forward
winding to reach START_ELEMENT. However when fetching endpoints from a
remote host meta data, PacketParserUtils.getParserFor(InputStream) is
used which doesn't do winding in any form. And thus, even though
HttpLookupMethodTest tests pass, this implementation would crash while
parsing remote host-meta.
Set 'connected' to 'true' as early as possible
We previously only set 'connected' after connectInternal()
returned. This could lead to notifyConnectionError() ignoring stream
error exceptions, e.g. when establishing TLS which happens also in
connectInternal(), because 'connected' was still 'false'.

We now set 'connected' to 'true' as soon as the transport (e.g. TCP,
BOSH, …) is connected. While this is in other ways also sensible, it
also allows notifyConnectionError() to handle exceptions in the early
connection stage.
