on package layer instead of Declarative Service (DS) approach.
Restructuring and cleanup of initialization process to ensure that all
internal config files are found by the corresponding bundle
classloaders.

This commit marks an important milestone with the addition of the
smack-android subproject. Smack is now able to run native on Android
without requiring any modifications, which makes the aSmack build
environment obsolete.
It was necessary to redesign the code for SASL authentication to achieve
this. Smack now comes with smack-sasl-provided for SASL implementations
that do not rely on additional APIs like javax for platforms where those
APIs are not available like Android.
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.
