and MultipleRecipient (XEP-33) related code in general (e.g. use
constants where possible).
For getMultipleRecipientServiceAddress() this means that
- the "synchronized (services)" block is removed
- ServiceDiscoveryManager is only retrieved once
Smack should not throw an IOException in case a stream got closed by
the remote peer and the user is trying to read() from the stream. This
commit fixes that, by making Smack return '-1' if the stream got
closed by the remote. An IOException will only be thrown if the user
tries to read from a stream that got already closed by *himself*.

This method was never intended to be part of the public API. It's also
critical that the given Runnables complete within a reasonable
time frame so that they don't block following ones.
Because of OSGi, no subproject of Smack (which is the same as a OSGi
bundle) must export a package that is already exported by another
subproject.
Therefore it was necessary to move the TCP and BOSH code into their own
packages: org.jivesoftware.smack.(tcp|bosh).
OSGi classloader restrictions also made it necessary to create a
Declarative Service for smack-extensions, smack-experimental and
smack-lagacy (i.e. smack subprojects which should be initialized), in
order to initialize them accordingly, as smack-core is, when used in a
OSGi environment, unable to load and initialize classes from other smack
bundles. OSGi's "Service Component Runtime" (SCR) will now take care of
running the initialization code of the particular Smack bundle by
activating its Declarative Service.
That is also the reason why most initialization related method now have an
additional classloader argument.
Note that due the refactoring, some ugly changes in XMPPTCPConnection
and its PacketReader and PacketWriter where necessary.
instead of using the old baseName=smack appendix=project.name approach,
we are now going convention over configuration and renaming the
subprojects directories to the proper name.
Having a prefix is actually very helpful, because the resulting
libraries will be named like the subproject. And a core-4.0.0-rc1.jar is
not as explicit about what it actually *is* as a
smack-core-4.0.0-rc1.jar.
