Solution: Fix the qt-android build

Solution: Don't print tar extraction verbosely

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

command line options.

I attempted to fix up the properties files manifests in the Makefile,
but neglected the end-of-line escape characters.  It was good enough
to pass whatever make dist on Linux did, but I had no Windows build
env to test in.  The broken change was in commit de4a4422.

Solution: increased to 4096 by default for all MSVC builds, for MinGW,
and for CMake.

Note: this is a speculative change, it needs confirmation before we
can keep it. Particularly, there is some doubt that changing this in
libzmq will affect upstream applications using libzmq.dll.

Updated:
    builds/zos/README.md: Updated with portability notes resulting
       from building zeromq/libzmq/master as of 2014-07-23 on z/OS
       UNIX System Services.

       Current z/OS UNIX status: all expected tests pass, except
       "test_proxy", which hangs and times out.

Updated:
    builds/zos/runtests: Extract tests to run from tests/Makefile.am
      at runtime, rather than hard coding tests list (to simplfy
      later maintenance).  test_*_tipc is excluded as BUILD_TIPC is
      not defined on z/OS UNIX System Services.  XFAIL_TESTS are also
      excluded, following current logic in tests/Makefile.am

Updated:
    builds/zos/cxxall: Defines ZMQ_HAVE_ZOS for platform portability;
        define ZMQ_USE_POLL _instead_ of ZMQ_FORCE_POLL, due to change
        in src/poller.hpp since ZeroMQ 4.0.x branch

Updated:
   builds/zos/README.md: Outlined process to transfer source from
     GitHub to z/OS UNIX System Services, including character set
     conversion for the source

Updated:
    README.md: Documented need for application to handle/ignore SIGPIPE

Updated:
   README.md:  describes process of building/using DLL
   makelibzmq: Build DLL as well as static library (unless BUILD_DLL=false)
   maketests:  Dynamically link to ../src/libzmq.so if present
   runtests:   Explicitly place ../src at start of LIBPATH
   makeclean:  Also remove files created for DLL
   cxxall:     Bumped updated date to reflect last edit

builds/zos includes:
    README.md: Overview of z/OS UNIX System Services port (Markdown)
    makelibzmq: Compile src/*.cpp and make libzmq.a
    maketests:  Compile tests/*.cpp and make test_* executables
    runtests:   Run tests/test_* executables and report results
    makeclean:  Remove built files
    zc++: /bin/c++ wrapper supplying required build arguments
    cxxall: run zc++ for all *.cpp files in directory

    platform.hpp: pre-generated (and edited) src/platform.hpp for z/OS
    test_fork.cpp: updated tests/test_fork.cpp that completes on z/OS
