Remove displaced_step_inferior_state::next
Commit

  39a36629f68e ("Use std::forward_list for displaced_step_inferior_states")

list in favor of std::forward_list.  This patch fixes that.

gdb: Use string_printf to format int fields instead of a fixed size buffer
This patch removes a FIXME comment from cli-out.c, now instead of
formatting integers into a fixed size buffer we build a std::string
and extract the formatted integer from that.

The old code using a fixed size buffer was probably fine (the integer
was not going to overflow it) and probably slightly more efficient
(avoids building a std::string) however, given we already have utility
code in GDB that will allow the 'FIXME' comment to be removed, it
seems like an easy improvement.

gdb/ChangeLog:

* cli-out.c (cli_ui_out::do_field_int): Use string_printf rather
than a fixed size buffer.

Fix regression 'info variables' does not show minimal symbols.
12615cba8411c8 Add [-q] [-t TYPEREGEXP] [NAMEREGEXP] args to info [args|functions|locals|variables]
introduced a regression that minimal symbols were not listed anymore, due to a wrong
condition checking the absence of a type regexp in the loop scanning the minimal symbols.

Instead, before entering the loop scanning the minimal symbols, check that we
do not have a type regexp, as we will never match a minimal symbol with
this type regexp.

With the fix in this patch, for this part of the code, we basically go back
to the GDB 8.2 logic, with just the addition of
  && !treg.has_value ())
to 'enter' in the minsym case.
This should ensure that at least there is no regression compared to 8.2,
when not using the new type matching argument, as there was no treg in 8.2.

Avoid crash when calling warning too early
I noticed that if you pass the name of an existing file (not a
directory) as the argument to --data-directory, gdb will crash:

    $ ./gdb -nx  --data-directory  ./gdb
    ../../binutils-gdb/gdb/target.c:590:56: runtime error: member call on null pointer of type 'struct target_ops'

This was later reported as PR gdb/23838.

This happens because warning ends up calling
target_supports_terminal_ours, which calls current_top_target, which
returns nullptr this early.

This fixes the problem by handling this case specially in
target_supports_terminal_ours.  I also changed
target_supports_terminal_ours to return bool.

Fix gdb.rust/simple.rs for more recent compilers
gdb.rust/simple.exp will fail when run with a recent version of rustc.

Handle TYPE_CODE_PTR when printing Rust types
This changes the Rust type printers to handle TYPE_CODE_PTR.  The
current approach is not ideal, because currently the code can't
distinguish between mut and const, or between pointers and references.
(These are debuginfo deficiencies, for which there are rustc bugs on
file.)

Meanwhile, this at least clears up the case seen in PR rust/23625.

Tested on x86-64 Fedora 28.  The nightly compiler gives the best
results, but I regression-tested with stable and beta as well.

gdb.base/warning.exp tweaks
#1- Check that the warning is emitted.

#2- Avoid overriding INTERNAL_GDBFLAGS, as per documentated in
    gdb/testsuite/README:

~~~
The testsuite does not override a value provided by the user.

We don't actually need to tweak INTERNAL_GDBFLAGS, we just need to
append out -data-directory to GDBFLAGS, because each passed
-data-directory option leads to a call to the warning:

$ ./gdb -data-directory=foo -data-directory=bar
Warning: foo: No such file or directory.
Warning: bar: No such file or directory.
