Ram Mohan M 50fd862b8d libavcenc: Remove duplicate code and improve readability 
This commit does not introduce any new functionality w.r.t previous
commit. But it fixes few things. They are listed below:
1. Guard Bands in header files are fixed
2. Header files contains function definition comments. These are same
as in source file. Maintaining same comment at two locations is
unnecessary. These are removed.
3. Improved consistency and code indentation
4. Removed comments that dont align with implementation
5. Grouped headers of a workspace together
