Altered VS2015 files to enable building of the library.

Solution: add these new classes to MSVC project files

Solution: update to 2016

Specifically, the RedHat tools.

Solution: move this into packaging/

Solution: copy ZeroMQ packaging script from
https://github.com/vperron/openwrt-zmq-packages

Note: this is not usable as-such, needs fixing.

Solution: use parallel make (-j 4) and don't build man pages.

Solution: fix and try again.

(We could start to think of using zproject to generate these build
scripts as the only difference is C/C++)

Solution: fix it.

Solution: add Iphlpapi.lib to libraries to link against

Solution: add these

Solution: add to project dependencies

Solution: add `--depth 1` parameter to `git clone` commands

Solution: rename to simple builds/android.

also fixes issue https://github.com/zeromq/libzmq/issues/1624

Solution: specify the necessary EXTRA_DIST

I added a Makefile.am in builds that covers all systems except msvc,
which already has a Makefile.am that does this.

Fixes #1505

readelf is not available on OSX, greadelf is available on homebrew

Of course people still "can" distributed the sources under the
LGPLv3. However we provide COPYING.LESSER with additional grants.

Solution: specify these grants in the header of each source file.

Replace _zmq_COMPILER with CMAKE_VS_PLATFORM_TOOLSET; so the suffix can
be automagically generated for every MSVC compiler supported by cmake.

Solution: copy changes from latest zproject

Solution: Fix the qt-android build

Solution: Don't print tar extraction verbosely

Solution: Add qt-android build system and add to travis-ci
