Fix membars around rtld internal mutex.
...
This fixes the most of lockups i observed with Open vSwitch
on NetBSD/amd64. ("most of" because it still occasionally
locks up because of other problems. see PR/49816)

Add basic support for indirect functions. It allows providing a public
...
function symbol with an implementation choosen at run time.
Refactor calls to functions by address in ld.elf_so to create temporary
function descriptors on the stack, if the address is not leaked outside.
Limitations:
- no support for initialising static storage with function pointers
- no support for unnamed resolver functions

Simplify. If we got called via a calls $n, *pcrel32, instead of constructing

a new stack frame, back up the PC by 7 and return back to the calls so it

Otherwise rebuild a new callframe and jump to the routine.
