HEVC fixes

[dantallis-edt]

Fixed some bugs affecting HEVC decode.

• Fixed emulation prevention byte removal in the case where the first byte after an emulation prevention byte was a 0 and hence could be the start of a new sequence containing an emulation prevention byte.
• Fixed algorithm for skipping bytes of NAL units based on nal_length. (The length already accounts for any emulation prevention bytes.)
• Fixed processing of rbsp_trailing_bits.
• Fixed some cases of uninitialized local variables being read.
• Fixed some cases of missing braces on if-statement body causing unintended (although probably harmless) execution of error testing and handling.
• Fixed some code causing compiler warnings.

Hi, what issue(s) does this PR address? also is there any test material to check its performance?

Hi Waqar - There isn't any specific issue for the things this addresses. Basically it fixes some bugs that I hit when I tried it with some HEVC content. I'm interested to know how mature the relevant (HEVC) code is in the validator -- I was surprised by some of the problems I hit. Let me know what you need to move this PR forwards -- should I create issue(s)? how/where can I contribute test material?

It would be very relavant to create issues in this regard to see what we are fixing. Thanks!
