2018-07-31lib: configfs: Globalize nested configfs callback functionsPaul Elder
Android now uses clang as the default C compiler, and gcc support is deprecated. clang doesn't support nested functions, which were used to implement callback functions in the ConfigFS code. We thus move the callbacks to the global scope.

2018-07-31lib: configfs: Fix asprintf return value usageKieran Bingham
The asprintf function returns -1, and leaves the first parameter undefined in case of an allocation error. This conflicts with the code's assumption that the parameter is set NULL on error. Check all return values of asprintf, and ensure that the string parameter is not used as a return value on error paths.

Split the project into a UVC gadget library and a test application. To avoid rolling out a custom build system, switch to CMake. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
