8636ab52f6 Deal with ASLR PIE executables, by recognizing that phdr != phdr->v_addr 
for PT_PHDR headers when the program has been loader to a vaddr other than
then one specified (a randomized one), and modifying the relocation base
address appropriately (idea from elad)

8b0637156f No need for stack_protector.o if USE_FORT is no. 
XXX: compiling a binary with -Wl,--dynamic-linker,${NETBSDSRCDIR}/libexec/...

558a5ffd0f rtld changes for PR bin/37347: 
- Apply patch from J.T. Conklin to execute .init/.fini functions in order.
- Support DF_1_INITFIRST and mark libc with DF_1_INITFIRST. Shared libs
  should be recording a dependency on libc, but it's too late to do that.

Ok christos@.

29353f93e2 Build a local copy of exit that doesn't call __cxa_finalize. It's not 
needed and drags in a lot of libc via free.

bf4b000d16 - Don't use the names malloc/free/etc, since we can end up pulling in libc's 
malloc which is not what we want.
- Remove ancient memory compaction hack. Realloc on free memory is now an
  error again (from joerg@).

Ok christos@.

40cfdb5e3a Use AT_SUN_EXECPATH instead of argv[0] for the executable name. This needs 
kernel support, which is not there yet, thus $ORIGIN is broken at this time.
This is ok, nothing uses it yet.

f7779133cd Don't remove the last component of filename before calling 
_rtld_digest_dynamic:  it is done in expand(), and doing it twice is once
too much.  This fixes $ORIGIN expansion for dependencies.

2ffe4b875f Use an elf note to handle pax arguments. This is a temporary solution to 
avoid wasting OS flag bits. In the future we'll probably use fileassoc to
achieve this (once there is a way to make fileassoc persistent) or in the
shorter term libelf, so that we can add and remove the note on demand instead
of burning bits on each binary. Of course since this is a tool, this means
that we'll need to think about how to handle libelf...

aac134252a From defend dot the dot world at gmail dot com: Sanitize environment variables 
for set{u,g}id binaries, so that in case they are playing with set{u,g}id
and exec'ing other binaries they don't get affected by the
LD_{PRELOAD,DEBUG,LIBRARY_PATH} environment setup. We leave LD_BIND_NOW alone.
There are no binaries affected in the base system.

0339fe6614 Coverity CID 2749: Fix another double free. Instead of removing that last 
free() call, change the allocation policy to leave the responsibility for
allocation/freeing the pathname to _rtld_map_object(), instead of having
the caller allocate it and _rtld_map_object() free it. This simplifies the
code a lot and it is more efficient.
