stagefright: httplive: Decouple block size from bandwidth estimate
A very small block size in PlaylistFetcher can lead to framework
overhead and difficulty streaming high bitrate content, but since
HTTPBase keeps a constant history of the past 100 HTTP reads, the
block size directly affects bandwidth estimation and in turn,
switching latency.
Add setBandwidthHistorySize() to HTTPBase to allow setting the
history size for bandwidth estimation. Call this within LiveSession
based on the current block size to ensure that the number of bytes
used for estimating bandwidth does not change if the block size is
changed in PlaylistFetcher.
Since a single TCP/IP packet can contain up to 64k of data, increase
the block size in PlaylistFetcher from 2k to lcm(188, 1024) or 47k to
avoid inaccuracies in read timings due to up to a comparable 47 reads
from the same locally-cached packet instead of from the network.
Also make HTTPBase::addBandwidthMeasurement() virtual to allow
bandwidth estimation extensions that do not rely on a history list.

stagefright: httplive: Fix deadlock for low duration clips
PlaylistFetcher buffers up to 3 * target-duration bytes of data,
but if a stream is slow (ie due to bad network conditions), a
buffer threshold of 10s is used to resume playback. This results
in an indefinite freeze as PlaylistFetcher has stopped buffering
before this threshold. Reduce the 10s threshold to be more in-sync
with PlaylistFetcher's buffering size.

stagefright: Fix bugs in playlist fetcher logic
1. Improve start time: start playback as soon as the target duration
or 10s was buffered.
2. Select playlist monitor time based on target duration to avoid
continuously missing the boat.
3. If "we miss the boat" we still must request a safe sequence
number (last - 3)
