rtld: Fix LD_LIBMAP under libmap override

rtld: Allows return pathname in dl_iterate_phdr dlpi_name

This is the behavior of Linux and also of FreeBSD since October 2014.
Until this point, dlpi_name returned the short name of the object unless
it wasn't defined, so the fallback was to return the pathname.

Returning the pathname in all cases is considered more useful and matches
the definition of Linux.

rtld: Add support for LD_LIBRARY_PATH_FDS env variable

This variable allows loading of shared libraries via directory descriptors
rather than via library paths. if LD_LIBRARY_PATH_FDS=3:4:12, the
directories represented by file descriptors 3, 4, and 12 will be searched
for shared libraries before the normal path-based mechanisms are used.
This allows the execution of unpriviledge binaries from within a Capsicum
sandbox even if they require shared libraries.  Note that Capsicum is not
available on DragonFly yet.

While here, adjust whitespace and rearrange a bit to minimize differences
with FreeBSD rtld.

rtld: Handle IFUNC symbols at non-PLT relocations

An example of this is initializing a global variable with a pointer to
ifunc.  This adds a symble type check and call resolver for STT_GNU_IFNC
symbol types whien processing non-PLT relocations, but only after
non-IFUNC relocations are done.  The two-phase processing is required
since resolvers may reference other symbols which most be ready to use
when resolver calls are done.

This restructures reloc_non_plt() to call find_symdef() and handle IFUNC
in a single place.

rtld: Add a postinit debugger hook

FreeBSD's dtrace(1) uses this hook to halt the "victim" process before its
entry point is called, at which point probes and DOF data are registered
with the kernel.  The r_debg_state hook cannot be used for this purpose,
as it is called before the program's init routines are invoked and in
particular before ODF is registered.  It may or may not be useful for
DragonFly by itself, but if dtrace every comes in, rtld will be ready.
