Add build toolchain to upload LibreOffice API to Maven Central

Set up the toolchain to create sources and javadocs artifacts in
addition to JARs created during the build. Use Buck build tool for
that: [1]. This is a fork of Google's build tool Blaze, created by
Xooglers at Facebook. This build tool (like Blaze itself) uses
Python to write build files.

Add needed tools and build files to install LibreOffice API artifacts
to local Maven repository or deploy them to Maven Central.

To build all needed artifacts LibreOffice must be built regularly
with GNU make first. To build the rest of the API (sources and
javadocs):

  $> buck build api

To replace version number with upcoming release version:

  $> solenv/bin/version.py 5.1.0

To install the API to local Maven repository:

  $> buck build api_install

To deploy the API to Maven Central:

  $> buck build api_deploy

Detailed documentation is added to document the prerequisites and
the workflow to upload LibreOffice API to Maven Central.
