chore: Refactor public headers and macros (#1275)
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.

feat: Replace glog with absl::log (#1274)
This deprecates --vmodule (not available in absl, mapping it to --v for
a very minimal sort of compatibility) and adds the absl::log flags
--minloglevel, --stderrthreshold, --log_backtrace_at, and --log_prefix.

style: Use angle-brackets for all internal headers (#1271)
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.

chore: Update URLs after moving projects (#1042)
Since a project URL is encoded into outputs, this means also updating
the golden output files.

KongQun Yang 3c26dfbd53 Estimate target duration in bandwidth calculation from initial blocks
We used to use the target segment duration provided by the user.
Unfortunately that does not work for iframe only playlist which
the target duration is effectively equal to the GOP duration.

In the new approach, we estimate the target duration from the initial
few blocks (10 blocks right now).

Fixes #610.

KongQun Yang 74df8d30cc Exclude short segments from peak bandwidth computation
https://tools.ietf.org/html/rfc8216#section-4.1
The peak segment bit rate of a Media Playlist is the largest bit rate
of any contiguous set of segments whose total duration is between 0.5
and 1.5 times the target duration.

Fixes #498.

KongQun Yang 5dd21179ec Do not use harmonic mean in bandwidth calculation
Instead, caclulating average bandwidth by dividing the sum of the
sizes of every segment by the sum of the durations of every segment.
This aligns with the requirement in HLS spec:
https://tools.ietf.org/html/draft-pantos-http-live-streaming-23 4.1.

BandwidthEstimator is also simplified to handle all blocks only.

Fixes #361

KongQun Yang 43be3c8e8b Use max bitrate in Representation@bandwidth instead of average bitrate
According to DASH spec (23009-1:2014):

Consider a hypothetical constant bitrate channel of
bandwidth with the value of this attribute in bits per second
(bps). Then, if the Representation is continuously delivered
at this bitrate, starting at any SAP that is indicated either by
@startwithsap or by any Segment Index box, a client can
be assured of having enough data for continuous playout
providing playout begins after @minbuffertime *
@bandwidth bits have been received (i.e. at time
@minbuffertime after the first bit is received).
For dependent Representations this value specifies the
bandwidth according to the above definition for the
aggregation of this Representation and all complementary
Representations.

This suggests that max bitrate should be used instead of average
bitrate.

Also cleaned up BandwidthEstimator code.

Fixes #376.

KongQun Yang 15ae26e12f Modify include headers to have "packager" in the path
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.
