This organizes all public headers for the library into
include/ and makes sure then don't rely on any headers from
other folders.
To accomplish this, this change also refactors macros.h,
media/base/macros.h, and status/status_macros.h into macros/classes.h,
macros/compiler.h, macros/crypto.h, macros/logging.h, macros/status.h,
and public/export.h. Now the export macros from macros.h live in
include/ to keep include/ from requiring anything else.
This refactor enables an install target that includes public headers
only.

This feeds into efforts to create a working install target.
The order of headers is still funky, and was "fixed" by clang-format,
but in a way that doesn't exactly align with the style guide. Further
cleanup of header order is coming in a follow-up PR.

mbedtls works very differently from BoringSSL, and many changes had to
be made in the details of AES decryption to accomodate this.
Beyond the basic changes required for mbedtls, part of the CTS padding
implementation had to be rewritten. I believe this is because of an
assumption that held for BoringSSL, but not for mbedtls. I was unable to
determine what it was, so I rewrote the CTS decryption using reference
materials. After this, tests passed.
The deterministc PRNG I used with mbedtls in the RSA tests differs
somewhat from the old one, so the expected vectors had to be
regenerated. The old determinstic tests were also disabled, and are now
re-enabled.
Since cryptography is sensitive code, and because there were far more
changes needed here than just updating some headers and utility function
calls, this has been split into its own PR for separate review from the
rest of the media/base porting work.
Issue #1047 (CMake porting)
Issue #346 (absl porting)
- 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.
Change-Id: I3fb4de0e8abbe891e6271e779373ba53f8df660d
- Remove EncryptionMode enums
- Remove AesEncryptor::InitializeWithRandomIv, replaced with
a static function AesCryptor::GenerateRandomIv, which should
be called to generate the iv if the iv is empty.
This change is to prepare support for CBCS and CENS pattern-based
protection schemes.

Change-Id: Icba35089d6e451cbea7ebbf5dd5674079f206390
- Create AesCryptor class as the common base
- AesCryptor::Crypt function will serve as an Encrypt function for
encryptor and a Decrypt function for Decryptor.
Change-Id: Ie91fb14964b5091786705bf510656f40d73af160
- Optimize and clean up encryption and decryption code.
- Consolidate various CBC encryption/decryption schemes into a
common class.
- Make it a constructor argument whether cipher block chain is
continuous across Encrypt/Decrypt calls.
- Also align protected region size as required in CENC spec.

- Part 1.
- Add packager command line argument "protection_scheme" to specify
protection scheme. Plumb through packager code to enable CBC
encryption/decryption.
- Add scheme type "cbc1" to sinf.
- Refactor AES encryptor and decryptor.
- Need more work in the subsample handling.

This does not support key-rotation and will give an error. This is
because WebM does not have a way to indicate a change in key ID using
media segments.

This is a follow up to previous CL.
Generated using command:
find {media,app,mpd} -type f -exec sed -r -i 's/#include "(.*)"/#include
"packager\/\1"/' {} \;
common.gypi and mpd.gyp are also modified to take the path change into
consideration.
