qpid-proton: new package

[Thomas:
   - Do not define QPID_PROTON_VERSION_MAJOR, and use proto-* instead,
     as suggested by Arnout.
   - Use QPID_PROTO_VERSION in QPID_PROTON_SITE, as suggested by
     Arnout
   - Remove useless comma in the openssl test, as suggested by Arnout
   - Change the post install target hook to remove the
     /usr/share/proton-*/ directory entirely, and not just the
     examples, since it only contains some license and documentation
     files.]

+Subject: [PATCH] proton-c: fix C compiler detection with _ARG1/_ARG2
+
+The C compiler commandline in CMake is composed by the concatenation of
+CMAKE_C_COMPILER + CMAKE_C_COMPILER_ARG1 + CMAKE_C_COMPILER_ARG2.
+
+In most use cases the two additional argument variables are empty, thus
+CMAKE_C_COMPILER can be used without any noticeable difference.
+
+The Buildroot embedded Linux build system [0], however, optionally exploits the
+CMAKE_C_COMPILER_ARG1 variable to speed up the cross-compilation of CMake-based
+packages using ccache. It does so by setting [1]:
+
+  CMAKE_C_COMPILER      = /path/to/ccache
+  CMAKE_C_COMPILER_ARG1 = /path/to/cross-gcc
+
+This works fine with other CMake-based packages, but proton-c's CMakeLists.txt
+calls gcc to extract the compiler version. It does so by calling
+"${CMAKE_C_COMPILER} -dumpversion", without honoring the two extra arguments.
+Within Buildroot with ccache enabled, this means calling
+"/path/to/ccache -dumpversion", which fails with the error:
+
+  ccache: invalid option -- 'd'
+
+Fix the compiler check by adding the two arguments.
