Release musl compatible binaries

[pires]

For the ones using Alpine Linux, it would be great to be have musl compatible binaries.

We didn't confirm that glibc vs musl was the problem, but it seems likely and only debug logging will provide more information.

I confirmed the problem was due to missing glibc. It is a musl vs glibc problem.

java.lang.UnsatisfiedLinkError: /tmp/libnetty-tcnative-linux-x86_641722850980897813599.so: Error loading shared library libcrypt.so.1: No such file or directory (needed by /tmp/libnetty-tcnative-linux-x86_641722850980897813599.so)

And then after a hack:

java.lang.UnsatisfiedLinkError: /tmp/libnetty-tcnative-linux-x86_64410176636862150824.so: Error relocating /tmp/libnetty-tcnative-linux-x86_64410176636862150824.so: pthread_mutex_consistent_np: symbol not found

Compiling on Alpine would probably be necessary.

@dimitarg thanks to your work I've automated the build of binaries for Alpine with Docker.
To whomever needs this, feel free to use and abuse.

@ejona86 thank you very much for your support. Without you I'd take ages to get this going, if ever.

And for posterity and those not familiar with java logging, this is the config I used to get debug log output (named log.properties):

handlers = java.util.logging.ConsoleHandler
java.util.logging.ConsoleHandler.level = ALL
io.netty.util.internal.NativeLibraryLoader.level = ALL

And then specified -Djava.util.logging.config.file=log.properties when running java.

@ejona86 would you mind adding that to the tcnative wiki?

Sorry to spam - came across this issue while looking up info related to alpine linux, and wondering if it could be closed as a duplicate of #111? They seem to be the same issue, and #111 has progressed further it seems.
