Prepare for radical source tree reorganization.zack/build-layout-experiment
All top-level files and directories are moved into a temporary storage directory, REORG.TODO, except for files that will certainly still exist in their current form at top level when we're done (COPYING, COPYING.LIB, LICENSES, NEWS, README), all old ChangeLog files (which are moved to the new directory OldChangeLogs, instead), and the generated file INSTALL (which is just deleted; in the new order, there will be no generated files checked into version control).

-/* crti.S puts a function prologue at the beginning of the .init and
- .fini sections and defines global symbols for those addresses, so
- they can be called as functions. The symbols _init and _fini are
- magic and cause the linker to emit DT_INIT and DT_FINI.
-
- This differs from what would be generated for ordinary code in that
- we save and restore the GP within the function. In order for linker
- relaxation to work, the value in the GP register on exit from a function
- must be valid for the function entry point. Normally, a function is
- contained within one object file and this is not an issue, provided
- that the function reloads the gp after making any function calls.
- However, _init and _fini are constructed from pieces of many object
- files, all of which may have different GP values. So we must reload
- the GP value from crti.o in crtn.o. */
