use cargo-c to produce cdy and static libs

cargo-c will produce a pkg-config file making it easier to statically
link plugins.

Also add 'static' features for plugins depending on < 1.14 as this is the
minimal required version to use static linking because of ABI changes in
core.

+## Building
+
+gst-plugins-rs relies on [cargo-c](https://github.com/lu-zero/cargo-c/) to
+generate shared and static C libraries. It can be installed using:
+
+```
+$ cargo install cargo-c
+```
+
+Then you can easily build and test a specific plugin:
+
+```
+$ cargo cbuild --manifest-path video/cdg/Cargo.toml
+$ GST_PLUGIN_PATH=$GST_PLUGIN_PATH:target/debug gst-inspect-1.0 cdgdec
+```
+
+The plugin can also be installed system-wide:
+
+```
+$ cargo cbuild --manifest-path video/cdg/Cargo.toml --prefix=/usr
+$ cargo cinstall --manifest-path video/cdg/Cargo.toml --prefix=/usr
+```
+
+This will install the plugin to `/usr/lib/gstreamer-1.0`.
+You can use `--libdir` to pass a custom `lib` directory
+such as `/usr/lib/x86_64-linux-gnu` for example.
+
+Note that you can also just use `cargo` directly to build Rust static libraries
+and shared C libraries. `cargo-c` is mostly useful to build static C libraries
+and generate `pkg-config` files.
