KongQun Yang acaa6b9b3b Move encryptor setup out of EncryptionHandler
Created EncryptorFactory to set up the encryptors.

This is part of the EncryptionHandler clean up to make it more modular
and testable.

KongQun Yang 86b10b6316 Fix pattern encryption when applying to patterns other than 1:9
We used to skip all the remaining bytes if the size is less than
|crypt_byte_block| blocks.

This interpretation is incorrect. We should only leave the last partial
16-byte block un-encrypted.

KongQun Yang 715ed939f1 Add instructions to build on Alpine Linux
- Also fixed compilations in Alpine Linux and other flavors of Linux.
- Added container versions in docker files to always use a verified
  version.

Closes #164.

KongQun Yang 8e96dd3b37 Address gcc build failures in some platforms
Seeing some failures on some platforms when compiled with clang
disabled:
  GYP_DEFINES="clang=0" gclient runhooks

Several changes to make it work:
1. Mark packager code with packager_code=1 in GYP definitions.
2. Disable a few checks in non-packager code, which we do not have
   direct control: dangling-else, deprecated-declarations,
                   unused-function
3. Fix the relevant errors in packager code.
4. Revert HAVE_STROPTS_H in curl config which is not available in
   all linux distributions.

Fixes #286
Fixes #293

Kongqun Yang 4c6e5f4fa6 Improve support for decryption of full sample encrypted cbcs
1. Allow encryption pattern of 0:0, which is treated as 1:0;
2. Remove the special handling of pattern 1:0 in pattern cryptor
   which may not always be correct;
3. Allow senc/saio/saiz boxes to be absent.

Kongqun Yang d08f6ae0cc Fix cbcs/cens behavior when applied to non video tracks
- Tracks other than video are protected using whole-block full-sample
  encryption as specified in ISO/IEC 23001-7:2016(E) 9.7, which is
  equivalent to a pattern of 1:0. This is different to the non pattern
  encryption counterparts.
- Also updated the code to allow the existence of other protection
  schemes in the original content, which will simply be ignored.
- The internal cryptor used by AesPatternCryptor should not use
  constant iv, add a DCHECK for that.
- Optimize AesPatternCryptor handling on the special pattern 1:0.

KongQun Yang 13202f91b6 Fix a few problems in AesCryptor classes
- CBC cryptors should accept IV of size 8 bytes - it will be zero
  extended to 16 bytes.
- Fixed iv() not updated problem in AesPatternCryptor.
- Replace kChainAcrossCalls with ConstantIvFlag enum flags.
