While testing this series I saw some errors from the Python test
suite. There were a couple of tests using "P" as a command; this
changes them to "p".

This patch introduces a bit of infrastructure -- namely, a minimal
std::optional analogue called gdb::optional, and an RAII template
class that works like make_cleanup_ui_out_tuple_begin_end or
make_cleanup_ui_out_list_begin_end -- and then uses these in the
Python code. This removes a number of cleanups and generally
simplifies this code.
std::optional is only available in C++17. Normally I would have had
this code check __cplusplus, but my gcc apparently isn't new enough to
find <optional>, even with -std=c++1z; so, because I could not test
it, the patch does not do this.

Currently, the breakpoint documentation refers to some commands taking breakpoint
"ranges" as arguments. We discussed this with Pedro and concluded that it would
be more accurate to speak in terms of breakpoint "lists", whose elements can optionally
be ranges. I also fixed a couple of minor mistakes in the docs.

of the 'commands' command to indicate that it takes a list argument.

This commit removes interp::quiet_p / interp_quiet_p /
interp_set_quiet, because AFAICS, it doesn't really do anything.
interp_quiet is only ever checked inside interp_set nowadays:
if (!first_time && !interp_quiet_p (interp))
{
xsnprintf (buffer, sizeof (buffer),
"Switching to interpreter \"%.24s\".\n", interp->name);
current_uiout->text (buffer);
}
I did a bit of archaelogy, and found that back in 4a8f6654 (2003), it
was also called in another place, to decide whether to print the CLI
prompt.
AFAICS, that condition is always false today, making that if/then
block always dead code. If we remove that code, then there are no
interp_quiet_p uses left in the tree, so we can remove it all.
There are two paths that lead to interp_set calls:
#1 - When installing the top level interpreter. In this case,
FIRST_TIME is true.
#2 - In interpreter_exec_cmd. In this case, the interpreter is always
set quiet before interp_set is called.
Grepping a gdb.log of an x86_64 GNU/Linux run for "Switching to
interpreter" (before this patch) doesn't find any hits.
I suspect the intention of this message was to support something like
a "set interpreter ..." command that would change the interpreter
permanently. But there's no such command.

While looking into PR rust/21097, I found that ptype of a
single-element enum in Rust did not always format the result properly.
In particular, it would leave out the members of a tuple struct.
Further testing showed that it also did the wrong thing for ordinary
struct members as well.
This patch fixes these problems. I'm marking it as being associated
with the PR, since that is where the discovery was made; but this
doesn't actually fix that PR (which I think ultimately is due to a
Rust compiler bug).
Built and regtested on x86-64 Fedora 25, using the system Rust
compiler. I'm checking this in.

- The interp->data field disappears, since we can put data in the
interpreter directly now. The "init" method remains in place, but
it now returns void.
- A few places check if the interpreter method is NULL before calling
it, and also check whether the method returns true/false. For some
of those methods, all current implementations always return true.
In those cases, this commit makes the C++-fied method return void
instead and cleans up the callers.

Ensure all local symbols precede external symbols in the dynamic symbol
table.
No local symbols are expected to make it to the dynamic symbol table
except for section symbols already taken care of, so this is really a
safeguard only against a potential BFD bug otherwise not so harmful,
which may become a grave one due to a symbol table sorting requirement
violation (see PR ld/20828 for an example). This means however that no
test suite coverage is possible for this change as code introduced here
is not normally expected to trigger.
Logically split then the part of the dynamic symbol table which is not
global offset table mapped, into a local area at the beginning and an
external area following. By the time `mips_elf_sort_hash_table' is
called we have the number of local dynamic symbol table entries (section
and non-section) already counted in `local_dynsymcount', so use it to
offset the external area from the beginning.

`min_got_dynindx', `max_unref_got_dynindx' and
`max_non_got_dynindx' members to the `bfd_size_type' data type.
(mips_elf_sort_hash_table): Adjust accordingly.
Make all hash table references throughout `mips_elf_sort_hash_table' use
`htab', simplifying code and improving readability.
bfd/
* elfxx-mips.c (mips_elf_sort_hash_table): Use `htab' throughout
to access the hash table.
Move the assertion on non-NULL `htab' in `mips_elf_sort_hash_table' to
the beginning, before the pointer is dereferenced (`mips_elf_hash_table
(info)' and `elf_hash_table (info)' both point to the same memory
location, differently typed).
bfd/
* elfxx-mips.c (mips_elf_sort_hash_table): Move assertion on
non-NULL `htab' to the beginning.
Match `$check_ld(source)' against "regex" rather than "regexp" in
reporting, correcting test framework diagnostics, e.g.:
tmpdir/undefined.o: In function `foo':
(.text+0x0): undefined reference to `bar'
failed with: <tmpdir/undefined.o: In function `foo':
(.text+0x0): undefined reference to `bar'>, no expected output
tmpdir/undefined.o: In function `foo':
(.text+0x0): undefined reference to `bar'
PASS: MIPS undefined reference
(current) vs:
tmpdir/undefined.o: In function `foo':
(.text+0x0): undefined reference to `bar'
failed with: <tmpdir/undefined.o: In function `foo':
(.text+0x0): undefined reference to `bar'>, expected: <\A[^\n]*\.o: In function `foo':\n\(\.text\+0x0\): undefined reference to `bar'\Z>
tmpdir/undefined.o: In function `foo':
(.text+0x0): undefined reference to `bar'
PASS: MIPS undefined reference
(corrected). No functional change.
ld/
* ld/testsuite/lib/ld-lib.exp (run_dump_test): Fix a typo,
s/regexp/regex/.
Include the detailed MIPS option description in the man page along with
other target descriptions and complementing the terse list earlier on.
gas/
* doc/as.texinfo (Overview): Select MIPS options for man page
inclusion.
This patch gets rid of this hack in mi_set_logging:
/* The tee created already is based on gdb_stdout, which for MI
is a console and so we end up in an infinite loop of console
writing to ui_file writing to console etc. So discard the
existing tee (it hasn't been used yet, and MI won't ever use
it), and create one based on raw_stdout instead. */
By pushing down responsibility for the tee creation to the
interpreter. I.e., pushing the CLI bits out of handle_redirections
down to the CLI interpreter's set_logging_proc method.
This fixes a few leaks that I spotted, and then confirmed with
"valgrind --leak-check=full":

One is fixed by transfering ownership of the log file to the tee. In
pseudo-patch, since the code was moved at the same time:
- out = new tee_file (curr_output, false, logfile.get (), false);
+ out = new tee_file (curr_output, false, logfile.get (), true);
The other is this bit in mi_set_logging:
else
{
+ delete mi->raw_stdout;
I tried to split the leak fixes to a smaller preparatory patch, but
that was difficult exactly because of the tee hack in
handle_redirections -> mi_set_logging.
