Module Name:    src
Committed By:   kamil
Date:           Mon Sep 21 16:08:57 UTC 2020

Modified Files:
        src/include: link_elf.h
        src/libexec/ld.elf_so: load.c rtld.c rtld.h

Log Message:
Upgrade the SVR4 RTLD r_debug protocol to version 1

Changes:
 - Add a new field r_ldbase in the r_debug struct.
 - Set r_version to 1.

This harmonizes the support with OpenBSD and Linux.
FreeBSD uses version 0 (or no version).
Solaris uses version 2 that is not implemented elsewhere and relies on
SVR4 specific design and interfaces.

Update the code comments as r_debug and link_map is used by other software
than GDB, namely: sanitizers, rump, LLDB.
