The new directory permission is set to the permission of the last
existing directory in the file path. If none of the directory exists,
it is default to 0755.
Previously we use base::CreateDirectoryAndGetError(), which always sets
the new directory permission to 0700, which is not what we want.

Only Marlin Adaptive Streaming Specification – Simple Profile is

Two additional updates:
- Remove FairPlay ContentProtection element from DASH mpd as FairPlay
does not define a signaling in DASH.
- Updated end to end test to include all DRMs we support.

This was introduced earlier to indicate FairPlay protection system. But
in fact, it is sufficient to just use the system id for the indication.

The VP9 level is computed when the container is missing a codec config
or if the level is missing from the codec config.
This fixes VP9 in ISO-BMFF files generated by FFmpeg v4.0.2 or earlier
which does not have level set in the codec config.

Note that AV1 specific boxes are not supported in this CL, i.e.
AV1 Forward Key Frame sample group entry 'av1f', AV1 Multi-Frame

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.

Renamed "FakeMediaHandler" to "CachingMediaHandler" so that it

Keep bundled binutil scripts but not downloading actual binaries by default.
Automatic downloading of binutils has been causing problems for some users:
see #164, #412, #440.
Using bundled binutils helps reduce linking time, but packager codebase is
relatively small, so the gain is not significant.
Local testing shows that the full build time increases from 1m42s to 1m50s, i.e.
an increase of about 8s, or ~8%.
User can still enable the usage of bundled binutils by running
'python src/packager/third_party/binutils/download.py' and set
'linux_use_bundled_binutils' and 'linux_use_bundled_gold' to 1 in GYP_DEFINES.

--io_block_size determines the buffer size for each read/write in
ThreadedIO.
A big io_block_size does not help much as long as --io_cache_size
is big enough.
Instead, it may cause problems. For example, Linux pipes block until
reading io_block_size number of bytes, which causes a large delay
when reading audio streams.

In some ISO-BMFF files, there is an initial non-zero composition offset,
but there is no EditList present.
This is against ISO-BMFF spec recommentation [1] and we believe in most
cases it is just missing the EditList.
[1] 14496-12:2015 8.6.6.1
It is recommended that such an edit be used to establish a presentation
time of 0 for the first presented sample, when composition offsets are
used.

- Also make it explicit that MemoryFile does not support opening an
already open file. An error will be returned when trying to open an
already open file. Previously the code may crash with memory problems.
- Also updated packager_test to use different test directories for
different tests.
Fixes Appveyor crash due to memory corruption: #449.
Appveyor may still fail but will contain a meaningful error logging.

This also ensures that it does not violate std::sort() requirement on
strict ordering, which is enforced in gcc/g++ though not in clang.
std::sort() strict ordering requirement:
std::sort() need a comparator that return true iff the first argument is
strictly lower than the second one. That is: must return false when they
are equal.
