piclist: Added new class piclist for list manipulations
Created new file piclist.cpp and piclist.h for linked list manipulation, there
will be
no intermediate storage in piclist, the piclist just link the TComPic object
piclist is used to Replace TComList<TComPic> and this will remove std::list
dependency in X265
