codec: expose modern send/receive packet/frame APIs 
avcodec_encode_video2()/avcodec_decode_video2/avcodec_encode_audio2()/avcodec_decode_audio4()
have been deprecated since FFmpeg 3.1, with modern
avcodec_send_packet()/avcodec_receive_frame()/avcodec_send_frame()/avcodec_receive_packet()
as replacements.

This commit adds send_packet(), send_eof() and receive_frame() to
decoder::Opened; send_frame(), send_eof() and receive_packet() to
encoder::Encoder to expose these modern APIs.

Fix filter::filter::PadIter to actually iterate 
Bug caught by clippy:

  error: offset calculation on zero-sized value
    --> src/filter/filter.rs:98:33
     |
  98 |             let pad = Pad::wrap(self.ptr.offset(self.cur));
     |                                 ^^^^^^^^^^^^^^^^^^^^^^^^^
     |
     = note: `#[deny(clippy::zst_offset)]` on by default
     = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#zst_offset

The problem is that `AVFilterPad` is zero-sized:

  #[repr(C)]
  #[derive(Debug, Copy, Clone)]
  pub struct AVFilterPad {
      _unused: [u8; 0],
  }

which is in turn due to `AVFilterPad` being an opaque type in
`libavfilter/avfilter.h`:

  typedef struct AVFilterContext AVFilterContext;
  typedef struct AVFilterLink    AVFilterLink;
  typedef struct AVFilterPad     AVFilterPad;
  typedef struct AVFilterFormats AVFilterFormats;

Doing pointer arithmetic on an opaque (incomplete) type doesn't work. We have
to use the proper FFI calls to obtain info on individual pads. The API has to
be tweaked a bit; hopefully it doesn't break user programs (if it does it
should only break bugged ones...).

Fixes #20.

software::scaling::context::run: fix srcSliceH argument 
Output height was erroneously used as the srcSliceH argument to
sws_scale, causing the output frame to be partially blank when scaling
down or outright erroring when scaling up. See documentation of sws_scale:

https://www.ffmpeg.org/doxygen/4.0/group__libsws.html#gae531c9754c9205d90ad6800015046d74

Fix issues related to duplicate enum variants 
C enums allow duplicate variants, but Rust enums don't. At some point bindgen
switched to generating duplicate variants as associated constants instead of
module-level constants, so use SomeEnum::* broke. Here we switch to associated
constants in the native API as well.
