It is possible for there to be multiple encryption init info structure.
For example, to support multiple key systems or in key rotation.  This
changes the AVEncryptionInitInfo struct to be a linked list so there
can be multiple structs without breaking ABI.

Some of these enums have gaps in between their values, since they correspond
to the values in various specs, instead of being an incrementing list.

Fixes segfaults when, for example, using the valid API call:

   av_color_primaries_from_name("jecdec-p22");

This was broken by bed670a1, which added
an assert that always failed.

This uses any devices it can find on the host system - on a system with no
hardware device support or in builds with no support included it will do
nothing and pass.

The change in 309d6607 to call device_init
when doing derivation missed this case - we should only call it if we
actually made a new device.

Regression since ece068a7.

The BufferHandle API was added in libva 1.4.0 / VAAPI 0.36.0.

- Parse schm atom to get different encryption schemes.
- Allow senc atom to appear in track fragments.
- Allow 16-byte IVs.
- Allow constant IVs (specified in tenc).
- Allow only tenc to specify encryption (i.e. no senc/saiz/saio).
- Use sample descriptor to detect clear fragments.

This doesn't support:
- Different sample descriptor holding different encryption info.
  - Only first sample descriptor can be encrypted.
- Encrypted sample groups (i.e. seig).
- Non-'cenc' encryption scheme when using -decryption_key.
