Cycles: Implement guarded allocator for STL classes The commit implements a guarded allocator which can be used by STL classes such as vectors, maps and so on. This allocator will keep track of current and peak memory usage which then can be queried. New code for allocator is only active when building Cycles with debug flag (WITH_CYCLES_DEBUG) and doesn't distort regular builds too much. Additionally now we're using own subclass of std::vector which allows us to implement shrink_to_fit() method which would ensure capacity of the vector is as big as it should be (without this making vector smaller will still use all previous memory allocated).

Cycles: remove prefix from source code file names Remove prefix of filenames that is the same as the folder name. This used to help when #includes were using individual files, but now they are always relative to the cycles root directory and so the prefixes are redundant. For patches and branches, git merge and rebase should be able to detect the renames and move over code to the right file.

Cycles: Fix static initialization order fiasco Initialization order of global stats and node types was not strictly defined and it was possible to have node types initialized first and stats after that. This will zero out memory which was allocated from the statistics causing assert failure when de-initializing node types.
