scan: fix very slow scanning for some files
The threshold in bytes for when to give up trying to decode a frame was
too big for a lot of streams. It was made large to accomodate 4K raw
video. Instead of counting bytes, count frames fed to the decoder.
This is more consistant regardless of video resolution and codec.

scan: enable HBTF_NO_IDR when not enough previews found
Setting this flag signals to libav to not wait for IDR or recovery
points before returning frames to us. Some videos have neither IDRs or
recovery points, so this fixes transcoding such video.
WinGui: Cancel Scan will now close the status panel if the scan cancellation fails for any reason. Rejigged the logging in the scan service to help debug intermittent failures of the scan completed event from firing.
WinGui: Audio Defaults: Improve the Mixdown dropdown. Only show supported mixdowns and automatically select the highest available mixdown if the encoder is limited and doesn't support the current selection.

Remove Fontconfig on Windows (#610)
* Remove Fontconfig on Windows
Let libass use its DirectWrite font provider backend instead of Fontconfig.
This eliminates Fontconfig's font cache generation delay that occurred
at the start of an encode after a system font was (un)installed or when
HandBrake was installed and used to burn text subtitles for the first time.
* Remove LibHB's dependency on Fontconfig when it's not used

x265: bump to version 2.3 (#437)
* x265: bump to version 2.2
Encoder enhancements
----------------------------------
1. Enhancements to TU selection algorithm with early-outs for improved
speed; use --limit-tu to exercise.
2. New motion search method SEA (Successive Elimination Algorithm)
supported now as –me 4
3. Bit-stream optimizations to improve fields in PPS and SPS for
bit-rate savings through --[no-]opt-qp-pps,
--[no-]opt-ref-list-length-pps, and --[no-]multi-pass-opt-rps.
4. Enabled using VBV constraints when encoding without WPP.
5. All param options dumped in SEI packet in bitstream when info
selected.
6. x265 now supports POWERPC-based systems. Several key functions also
have optimized ALTIVEC kernels.
API changes
-------------------
1. Options to disable SEI and optional-VUI messages from bitstream made
more descriptive.
2. New option --scenecut-bias to enable controlling bias to mark
scene-cuts via cli.
3. Support mono and mono16 color spaces for y4m input.
4. --min-cu-size of 64 no-longer supported for reasons of visual quality
(was crashing earlier anyways.)
5. API for CSV now expects version string for better integration of x265
into other applications.
Bug fixes
--------------
1. Several fixes to slice-based encoding.
2. --log2-max-poc-lsb‘s range limited according to HEVC spec.
3. Restrict MVs to within legal boundaries when encoding.
* x265: bump to version 2.3
Encoder enhancements
----------------------------------
1. New SSIM-based RD-cost computation for improved visual quality,
and efficiency; use --ssim-rd to exercise.
2. Multi-pass encoding can now share analysis information from prior
passes (in addition to rate-control information) to improve performance
and quality of subsequent passes; to your multi-pass command-lines that
use the --pass option, add --multi-pass-opt-distortion to share
distortion information, and --multi-pass-opt-analysis to share other
analysis information.
3. A dedicated thread pool for lookahead can now be specified with
--lookahead-threads.
4. --dynamic-rd dynamically increase analysis in areas where the bitrate
is being capped by VBV; works for both CRF and ABR encodes with VBV
settings.
5. The number of bits used to signal the delta-QP can be optimized with
the --opt-cu-delta-qp option; found to be useful in some scenarios for
lower bitrate targets.
6. Experimental feature option:–aq-motion adds new QP offsets based on
relative motion of a block with respect to the movement of the frame.
API changes
-------------------
1. Reconfigure API now supports signalling new scaling lists.
2. x265 application’s csv functionality now reports time (in milliseconds)
taken to encode each frame.
3. --strict-cbr enables stricter bitrate adherence by adding filler bits
when achieved bitrate is lower than the target; earlier, it was only
reacting when the achieved rate was higher.
4. --hdr can be used to ensure that max-cll and max-fall values are
always signaled (even if 0,0).
Bug fixes
--------------
1. Fixed incorrect HW thread counting on MacOS platform.
2. Fixed scaling lists support for 4:4:4 videos.
3. Inconsistent output fix for --opt-qp-pss by removing last slice’s
QP from cost calculation.
4. VTune profiling (enabled using ENABLE_VTUNE CMake option) now also
works with 2017 VTune builds.

sync: fix small video dejitter error
This very small error snowballs into a crash in x264 :-p
If the amount of jitter on the first frame in the queue was small
(about 1 tick) then jitter would not be removed from that frame.
This extra tick of jitter can appear on different frames depending
on when frame arrives and how much has been queued. This very small
amount of randomness lead to problems in the VFR filter. A frame
duration difference as small as 1 tick can lead to an extra frame
getting duplicated when doing CFR. When doing 2 pass encoding, this
extra frame causes x264 to crash at the end of the 2nd pass.
