This commit adds fixed-size allocation buffers. The primary use case is in NSS modules, where dynamically sized data is stored in a fixed-size buffer provided by the caller. Other uses include a replacement of mempcpy cascades (which is safer due to the size checking inherent to allocation buffers).
