Added a flag --strip_parameter_set_nalus. When enabled, parameter
set NAL units, SPS/PPS for H264 and SPS/PPS/VPS for H265, are stripped
from frames when converting NAL byte stream (AnnexB stream) to NAL
unit stream, which generates avc1/hvc1; otherwise they are not
stripped, and avc3/hev1 is generated.
Parameter set NAL units should not be stripped if they are varying
in the frames otherwise the frames may fail to be decoded.
The flag is enabled by default as we don't usually see varying
SPS/PPS/VPS and it is more space efficient with them stripped.
Set --strip_parameter_set_nalus=false to disable the flag if there
are varying SPS/PPS/VPS in the frames. This addresses #206.

- luma_weight_l0_flag, luma_weight_l1_flag,
chroma_weight_l0_flag, chroma_weight_l1_flag were there but not set.
- The user should use the values in pred_weight_table_l0 and
pred_weight_table_l1 instead which are set.

The spec actually requires all NAL units to be escaped, so there
is no need to escape it again.
NAL byte stream is one demarcation method; NAL unit stream is another
demarcation method. Regardless of the demarcation method used, the
requirement for NAL unit is the same. See the last paragraph of
7.4.1 NAL unit semantics on the requirement on emulation prevention bytes.

CENCv3 recommends only encrypting video data in slice NALs. Slice
data partition NALs should not be encrypted.
In the code, differentiate is_vcl and is_video_slice. They are the
same for H265; for H264, vcl NALs include slice data partition NALs
but video_slice NALs do not.

- nalu_data points to the beginning of the nalu, instead of
beginning of the slice header which excluded the nalu
header.
- nalu_size is the size of the whole nalu.
- header_bit_size calculation is corrected. The size used to exclude
emulation prevention bytes.

- Add decrypt_config in media sample and stream.
- Update subsamples when converting NAL unit to bytestream.

1. Replace STLDeleter with unique_ptr in container, which is
supported in C++11
2. Replace string_as_array with &string[0] which is guaranteed
to work in C++11

In H264, there may be multiple consecutive video slice NAL units
in the same frame. The original code assigns a new access unit
for every video slice NAL unit, which is incorrect.
Fixes#134.

Packager should not care about this flag, whether it is supported
is up to the decoder.
Closes#126

Before, we converted the WebM configuration to MP4 in the video
client, however this lead to a bug when fields were missing. So
now don't convert until the cluster parser so the extra info from
the stream can be added.
This also fixes a bug where the value was not printed in the warning
logs.
