bd8a901f9e xml-support.c: Use std::string for growing string buffer
This main idea behind this patch is this change to xml-support.c:scope_level

  -  /* Body text accumulation.  This is an owning pointer.  */
  -  struct obstack *body;
  +  /* Body text accumulation.  */
  +  std::string body;

... which allows simplifying other parts of the code.

In target_fetch_description_xml, we want to distinguish between
returning "success + empty std::string" and "no success", and
gdb::optional is a natural fit for that.

d35d19584c gdb::optional unit tests
I thought I'd add some unit tests to make sure gdb::optional behaved
correctly, and started writing some, but then thought/realized that
libstdc++ already has extensive testing for C++17 std::optional, which
gdb::optional is a subset of, and thought why bother writing something
from scratch.  So I tried copying over a subset of libstdc++'s tests
(that ones that cover the subset supported by gdb::optional), and was
positively surprised that they mostly work OOTB.  This did help shake
out a few bugs from what I was implementing in the previous patch to
gdb::optional.  Still, it's a good chunk of code being copied over, so
if people dislike this copying/duplication, I can drop this patch.

22796e972f More gdb::optional features
Currently we can't use gdb::optional<T> as function return type,
because gdb::optional's copy ctor is deleted.  For example, with:

  gdb::optional<int> function ()
  {
    gdb::optional<int> opt;
    ....
    return opt;

we get:

  src/gdb/foo.c: In function ‘gdb::optional<int> foo()’:
  src/gdb/foo.c:75:10: error: use of deleted function ‘gdb::optional<T>::optional(const gdb::optional<T>&) [with T = int]’
     return opt;
	    ^
  In file included from src/gdb/foo.c:68:0:
  src/gdb/common/gdb_optional.h:53:3: note: declared here
     optional (const optional &other) = delete;
     ^

I started by fixing that, and then ran into another missing feature,
also fixed by this patch.

The next feature I'm missing most from gdb::optional<T> compared to
std::optional<T> is construction/move/assignment from a T, instead of
having to default construct an gdb::optional and then use
optional::emplace(....).

For example:
  gdb::optional<std::string> function ()
  {
    gdb::optional<std::string> opt;
    std::string str;
    ...
    opt.emplace (std::move (str));
    return opt;
vs
  gdb::optional<std::string> function ()
  {
    std::string str;
    ...
    return str;

The copy/move ctor/assign methods weren't initialy implemented because
std::optional supports construction from a type U if U is convertible
to T too, and has rules to decide whether the ctors are
explicit/implicit based on that, and rules for whether the ctor should
be trivial or not, etc., which leads to a much more complicated
implementation.

If we stick to supporting copy/move construction/assignment of/to an
optional<T> from exactly only optional<T> and T, then all that
conversion-related complication disappears, and we still gain
convenience in most use cases.

The patch also makes emplace return a reference to the constructor
object, per C++17 std::optional, and adds a reset method, againt
because std::optional has one and it's trivial to support it.  These
two changes are a requirement of the gdb::optional unit testing patch
that will follow.

0550c95595 Make inferior a class with cdtors, and use new/delete
struct inferior became a non-POD when enum_flags was made a non-POD,
so we should be allocating/destroying inferiors with new/delete, etc.

441d7c9378 watch_command_1: Fix dangling frame access
While working on some changes to switch_to_thread, I inadvertently
make switch_to_thread call reinit_frame_cache more frequently, even
when the thread didn't change.  This exposed a latent bug in
watch_command_1, where we're referencing a frame after
creating/inserting breakpoints, which potentially calls
reinit_frame_cache if it needs to install breakpoints with a different
thread selected.

cases.  I.e., save any frame-related information we might need before
creating a breakpoint.

808480f667 fork-child.c: Avoid unnecessary heap-allocation / string copying
The previous change to fork-child.c converted the argv building from
an alloca-allocated array of non-owning arg pointers, to a std::vector
of owning pointers, which results in N string dups, with N being the
number of arguments in the vector, and then requires manually
releasing the pointers owned by the vector.

This patch makes the vector hold non-owning pointers, and avoids the
string dups, by doing one single string copy of the arguments upfront,
and replacing separators with NULL terminators in place, like we used
to.  All the logic to do that is encapsulated in a new class.

With this, there's no need to remember to manually release the argv
elements with free_vector_argv either.

c08bb8dd9b Rewrite bfd error handler
This steals _doprnt from libiberty, extended to handle %A and %B.
Which lets us do away with the current horrible %A and %B handling
that requires all %A and %B arguments to be passed first, rather than
in the natural order.

	* bfd.c (PRINT_TYPE): Define.
	(_doprnt): New function.
	(error_handler_internal): Use _doprnt.

e6ddc3bfed XCNEW gdbarch_tdep in rl78 and rx
"struct gdbarch_tdep" is XNEW'ed in rl78 and rx, so the memory is not
cleared.  As the result, tdep->rl78_psw_type is never initialized
properly.

  struct gdbarch_tdep *tdep = gdbarch_tdep (gdbarch);

  if (tdep->rl78_psw_type == NULL)
    {
      tdep->rl78_psw_type = arch_flags_type (gdbarch,
					     "builtin_type_rl78_psw", 1);

The bug is found by my unit test in the following patch.

f5336ca55c breakpoint.c: bp_location (the array) shadows bp_location (the type)
The bp_location array has the same name as the "struct bp_location",
type preventing refering to the structure without the "struct" inside
breakpoint.c.  I.e., we must write:

 "new struct bp_location;"

instead of:

 "new bp_location"

Rename the array and the associated variables/functions to avoid the
shadowing.

be628ab814 Create gdb_termios.h (and cleanup gdb/{,gdbserver/}terminal.h)
As requested, I'm sending this as a separate patch because it is ready
to be included as-is.

The idea here is that both gdb/terminal.h and gdb/gdbserver/terminal.h
share the same code, which is responsible for setting a bunch of
defines on based on the presence of termios.h and a few other headers.
This simple patch just moves this common code to common/gdb_termios.h
and makes the necessary adjustments on both GDB and gdbserver so that
they can use this new header.  It also implements the some header
checks on common/common.m4.

As a bonus, gdb/gdbserver/terminal.h can be removed because it's now
empty.

Built on x86_64, no regressions found.

	* Makefile.in (HFILES_NO_SRCDIR): Add "common/gdb_termios.h".
