This commit includes a number of changes to enable loading of PIE executables: - The loader in srv.init checks for a `PT_INTERP` segment in the program its loading, and if it exists, loads the specified interpreter and passes control to it instead of the program itself. - Added ld.so the dynamic linker executable and set it as the interpreter for all user-target programs. - Program initial stack changed again to now contain a number of possible tagged structures, including a new one for ld.so's arguments, and for passing handles tagged with protocol ids. - Added a stub for a new VFS protocol. Unused so far, but srv.init will need to serve VFS requests from ld.so once I transition libraries to shared libs for user-target programs. (Right now all executables are PIE but statically linked, so they only need internal relocations.) - Added 16 and 8 bit variants of `util::bitset`. This ended up not being used, but could be useful.
