_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

For now, this also still uses the existing realpath implmentation
and emits a syslog if we see differening results. Once we have run
with that for a little while we will remove the old code

If the time is wrong, we cannot validate dnssec, leading to failed
DNS lookups, so we cannot adjust or set the time.  Work around this
by repeating a failed DNS lookup with a lookup with the DC (check

- put functions and data which are only used before calling the executable's
start function into their own page-aligned segments for unmapping
(only done on amd64, arm64, armv7, powerpc, and sparc64 so far)
- pass .init_array and .preinit_array functions an addition argument which
is a callback to get a structure which includes a function that frees
the boot text and data
- sometimes delay doing RELRO processing: for a shared-object marked
DF_1_INITFIRST do it after the object's .init_array, for the executable
do it after the .preinit_array
- improve test-ld.so to link against libpthread and trigger its initialization
