0.11.0: 2018 Sep 13

* updated to pd vanilla 0.48-2
* the libpd C core is now thread safe
* support for multiple libpd instances is more or less working, see new
  libpd_*_instance() api and pdtest_multi/pdtest_thread C samples,
  note: language wrappers are not yet updated with the new APIs
* libpd can now open a patch in the Pd vanilla GUI directly, see the new
  libpd_startgui()/libpd_stopgui() functions and the pdtest_gui C sample
* enable/query verbose printing with new libpd_set_verbose()/libpd_get_verbose()
  functions (Pierre Guillot)
* no longer build s_file.c as desktop settings have no real meaning for libpd,
  this also fixes iOS build error due to system calls being removed in Xcode 9
* libpd binaries built with MinGW now work in Visual Studio (see readme)
* updated ringbuffer atomics macros to use C11 stdatomics.h if available,
  this fixes deprecation warning on macOS 10.12
* fixed possible crash due to stale printhook pointer (reported by Niall Moody)
* fixed bug in libpd_sysex which masked 8 bit bytes, the MIDI spec allows 8 bit
  bytes except for realtime messages
* fixed [declare -stdpath] crash (reported by Pierre Guillot)

* Makefile: UTIL=true, EXTRA=true, LOCALE=false are now defaults
* Makefile: added MULTI option to build libpd with multiple instance support
* Makefile: installs libpd .def and .lib files on Windows
* Makefile: builds working pd.dll needed by externals on Windows (Spacechild1)
* Makefile: C++ headers are now conditionally installed if built with UTIL=true
* Makefile: use default optimzations from pd: fast math, loop unrolling, etc

* C: const float src argument in libpd_write_array (Pierre Guillot)

* C++: transitioned to all-header library and removed "cpplib" make target,
       you may need to add `libpd_wrapper/util` to you include paths, this also
       makes it possible to use libpd compiled by MinGW & C++ with Visual Studio

* Java: added PortAudio support, build using PORTAUDIO=true makefile option
* Java: allow custom natives loading by implementing PdBaseLoader class (MGSX)
* Java: fixed Windows pthread naming in PdBaseLoader (reported by Pooya Moradi)
