It basically rewrites most of filelist.c, with some more limited changes in other areas of filebrowser. From user perspective, it: * Removes some info in 'long' drawing mode (owner, permissions) - OS-specific data that do not really matter in Blender! * Makes short/long display 'fixed' size (among four choices, like thumbnails mode). * Allows to list several layers of dirtree at once, in a flat way (inside .blend files and/or real directories). * Consequently, adds datablocks types filtering. * Uses way less RAM when listing big directories, especially in thumbnail mode (we are talking of several hundred of MiB spared). * Generates thumbnails way faster. From code perspective, it: * Is ready for asset engine needs (on data structure level in filebrowser's listing). * Simplifies and makes 'generic' file listing much lighter. * Separates file listing in three different aspects: ** 'generic' filelisting (in BLI), which becomes a shallow wrapper around stat struct. ** 'filebrowser drawing' filelisting, which only contains current visible subset of the whole list (sliding window), with extra drawing data (strings for size, date/time, preview, etc.). ** 'asset-ready' filelisting, which is used for operations common to 'basic' filehandling and future asset-related one. * Uses uuid's to handle file selection/state in the browser, instead of using flags in filelisting items. * Uses much lighter BLI_task handling for previews, instead of heavy 'job' system (using the new 'notifier' timer to handle UI refresh, in similar way to jobs). * Moves .blend datablocks preview handling to IMB_thumbnail (necessary to avoid storing all datablock previews at once, and gives better consistency and performances too).
