KongQun Yang cb8b27e491 Properly initialize crypto engine to enable HWAES
Call CRYPTO_library_init to properly initialize crypto engine, which
enables AES-NI (Hardware AES) if it is supported by CPU.

Also added a performance benchmark test.

Closes #198.

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 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.

KongQun Yang 2ac57bf9b9 Use FOURCC as protection scheme parameter
- 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.

  encryptor and a Decrypt function for Decryptor.
