Simplify format_warning_at_substring API

The format_warning_at_substring API has a rather clunk way of indicating
the location of the pertinent param (if any): a source_range * is passed
in, which can be NULL.  Doing so requires extracting a range from the
location_t and passing around a pointer to it, or NULL, as needed.

This patch simplifies things by eliminating the source_range * in
favor of a location_t, with UNKNOWN_LOCATION used to signify that
no param location is available.

Add gnu::unique_ptr

This is a version of the patch posted by Trevor Saunders on 2017-07-31,
for which he wrote:
> For most of the history of this see
>   https://sourceware.org/ml/gdb-patches/2016-10/msg00223.html
> The changes are mostly s/gdb/gtl/g

This version was updated by me (dmalcolm) adding these changes:
- renaming of "gtl" to "gnu" (3 letters, and one of the ones Richi
  proposed, and not a match for "*tl")
- renaming of DEFINE_GDB_UNIQUE_PTR to DEFINE_GNU_UNIQUE_PTR
- renaming of xfree_deleter to xmalloc_deleter, and making it
  use "free" rather than "xfree" (which doesn't exist)
- added a gcc/unique-ptr-tests.cc
- implement unique_xmalloc_ptr<T[]> (taken from gdb, but changing
  "xfree" to "free", and adding support for pre-C++-11)
