Most of the churn here occurs because 'filesize' is one of the redefined filesystem functions, but some of the structs used by the native FS code also include a 'filesize' member variable which gets renamed by the macro in some but not all source files. It's easier to rename 'filesize()' to 'ffilesize()' rather than try to clean up the macro mess or renaming the struct members. There is weirdness with root_realpath() which now breaks on native builds because it was assumed to be unprefixed there. dir_get_info() was unprefixed everywhere but this just seems inconsistent; make it follow the FS_PREFIX() convention too.
