This change makes public the current kargs API in src/libostree/ostree-kernel-args.c and adds documentations. Upstreams the new kargs API from rpm-ostree/src/libpriv/rpmostree-kargs-process.c Merges libostree_kernel_args_la_SOURCES to libostree_1_la_SOURCES in Makefile-libostree.am Upstreams tests/check/test-kargs.c from rpm-ostree. Closes: #1833 Closes: #1869 Approved by: jlebon
