Complete the ld.so boot cleanup: move most libc initialization from

_csu_finish() to _libc_preinit(), which is an .init_array function
in shared libc (and mark it INITFIRST) or a .preinit_array function
in static libc, grabbing the _dl_cb callback there from ld.so.  Then
in _csu_finish(), invoke the dl_clean_boot() callback to free ld.so's
startup bits before main() gets control.

Other cleanups this permits:
 - move various startup structures into .data.rel.ro
 - the dl* stubs in libc can be strong and call the callbacks provided
   via _dl_cb
 - no longer need to conditionalize dlctl() calls on presence of _DYNAMIC
