OSGify wasync

[sakno]

Please, add maven-bundle-plugin to pom.xml of wasync library and allow to install this library as OSGi bundle.

There are two workarounds that enable to use wasync in OSGi envrionment:

1. Embed wasync into the custom bundle via pom.xml, similar to workaround described here
2. Apache Karaf specific workaround: Using wrap protocol in the KAR archive deployment descriptor (named as features.xml):

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<features xmlns="http://karaf.apache.org/xmlns/features/v1.2.0" name="wasync-feature">
    <feature name="wasync-feature" description="" version="1.0.0">
        <details>Atmosphere wAsync feature</details>
        <bundle>mvn:io.netty/netty/3.10.0.Final</bundle>
        <bundle>mvn:com.ning/async-http-client/1.9.5</bundle>
        <bundle>wrap:mvn:org.atmosphere/wasync/2.0.0$Export-Package=org.atmosphere.wasync.*;version="2.0.0"</bundle>
    </feature>
</features>
