Fixes two leakage problems on the wood blocks sample
- Removes DC which causes leakage with no masking
- Detect leakage by comparing short-MDCT energy to long-MDCT energy
  and boost allocation for bands with leakage

Haven't tested it much and not sure not to use it without risk
for high-quality streams that may change bandwidth

Also, reducing the VBR rate on panned mono

Should be mostly usable now.

Add project files for Opus tests, fixup test source for Win32.

This is what got submitted as version 01

This is the less-surprising behavior and will hopefully
result in fewer corner case bugs (e.g. losing gain
after seeking). This commit also updates the documentation.

The last commit changed some of the multistream tests to use a
dual-mono setup instead of a single-stereo setup. Some of the
accompanying explicit valgrind checks were still setup to
look for stereo streams.

This CTL was requested by Nicolas George for FFmpeg.

Thanks to Ron Lee for pointing it out.
