doc: Improve documentation about MI thread output
I noticed that the documentation on how the info about threads is output
in MI is duplicated and not up to date. The duplication is between the
"GDB/MI Thread Information" page and the -thread-info result
description.
I improved the "GDB/MI Thread Information" page a bit and referred to it
in the -thread-info doc. This way, the -thread-info doc is more precise
(it did not mention the "threads" and "current-thread-id" attributes)
and concise.
gdb/doc/ChangeLog:
* gdb.texinfo (GDB/MI Thread Information): Add missing
fields, re-word some things.
(GDB/MI Thread Commands): Describe fields found in the output of
-thread-info, remove description of fields in the
thread output tuple, replace with a cross-reference to "GDB/MI
Thread Information".

Remove dead code and "current" field from MI thread output doc
The MI documentation says that -thread-info output contains a "current"
field in the current thread tuple, with the value "*". Current GDB
master does not do this, and I couldn't find any GDB version that did.
I suspect that it was never the case.
The code that would correspond to this in print_thread_info_1 is
essentially dead code. The calls to uiout->text end up in
mi_out::do_text, which is empty.
This patch removes the documentation bit and the dead code. This
"current" field is not necessary, since -thread-info outputs a
"current-thread-id" field.
gdb/ChangeLog:
* thread.c (print_thread_info_1): Remove dead code.
gdb/doc/ChangeLog:
* gdb.texinfo (GDB/MI Thread Commands): Remove "current" field
from -thread-info output.

i386: Avoid dynamic symbol with GOT reference in PIE
GOT reference to global symbol in PIE will lead to dynamic symbol. It
becomes a problem when "time" or "times" is defined as a variable in
an executable, clashing with functions of the same name in libc. If
a symbol isn't undefined weak symbol, don't make it dynamic in PIE and
generate R_386_RELATIVE relocation.

Simplify regcache_restore
This patches removes the 2nd argument of regcache_restore, because it
is only called by regcache_cpy. In regcache_cpy, if regcache_restore
is called, dst is not readonly, but src is readonly. So this patch
adds an assert that src is readonly in regcache_restore.
regcache_cook_read read everything from a readonly regcache cache
(src)'s register_buffer, and register status is from ->register_status.

Skip PIE indirect5 and indirect6 tests on i386
On i386, since GOT reference is needed to access global symbols in PIE,
those symbols are made dynamic. Crash happens when there is a reference
to the same global symbol with a different symbol type in a shared
object. Since mixing different types of the same symbol doesn't work in
general, this patch skips those tests on i386 as well as compiles non-PIE

Handle symbol defined in IR and referenced in DSO
We need to make an IR symbol visible if it is defined in an IR object
and referenced in a dynamic object. When --as-needed is used, since
linker removes the IR symbol reference of the dynamic object if the
dynamic object isn't needed in the first pass, the IR definition isn't
visible to the dynamic object even if the dynamic object becomes needed
in the second pass. Add dynamic_ref_after_ir_def to bfd_link_hash_entry
to track IR symbol which is defined in an IR object and later referenced
in a dynamic object. dynamic_ref_after_ir_def is preserved when restoring
the symbol table for unneeded dynamic object.

Fix removing inferiors from within "thread apply" commands
This patch fixes an internal error exposed by a test that does
something like:
define kill-and-remove
kill inferiors 2
remove-inferiors 2
end
# Start one inferior.
start
# Start another inferior.
add-inferior 2
inferior 2
start
# Kill and remove inferior 1 while inferior 2 is selected.
thread apply 1.1 kill-and-remove
The internal error looks like this:
Thread 1.1 (Thread 0x7ffff7fc2700 (LWP 20677)):
[Switching to inferior 1 [process 20677] (gdb/testsuite/outputs/gdb.threads/threadapply/threadapply)]
[Switching to thread 1.1 (Thread 0x7ffff7fc2700 (LWP 20677))]
#0 main () at src/gdb/testsuite/gdb.threads/threadapply.c:38
38 for (i = 0; i < NUM; i++)
src/gdb/inferior.c:66: internal-error: void set_current_inferior(inferior*): Assertion `inf != NULL' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) FAIL: gdb.threads/threadapply.exp: kill_and_remove_inferior: try kill-and-remove: thread apply 1.1 kill-and-remove (GDB internal error)
There are several problems around this area of the code. One is that
in do_restore_current_thread_cleanup, we do a look up of inferior by
ptid, which can find the wrong inferior if the previously selected
inferior exited and some other inferior was started with a reused pid
(rare, but still...).
The other problem is that the "remove-inferiors" command rejects
attempts to remove the current inferior, but when we get to
"remove-inferiors" in a "thread apply THR remove-inferiors 2" command,
the current inferior is the inferior of thread THR, not the previously
selected inferior, so if the previously selected inferior was inferior
2, that command still manages to wipe it, and then gdb restores the
old selected inferior, which is now a dangling pointer...
So the fix here is:
- Make make_cleanup_restore_current_thread store a pointer to the
previously selected inferior directly, and use it directly instead
of doing ptid look ups.
- Add a refcount to inferiors, very similar to thread_info's refcount,
that is incremented/decremented by
make_cleanup_restore_current_thread, and checked before deleting an
inferior. To avoid duplication, a new refcounted_object type is
added, that both thread_info and inferior inherit from.

Make inferior::detaching a bool, and introduce scoped_restore::release()
I left making inferior::detaching a bool to a separate patch, because
doing that makes a make_cleanup_restore_integer call in
infrun.c:prepare_for_detach no longer compile (passing a 'bool *' when
an 'int *' is expected). Since we want to get rid of cleanups anyway,
I looked at converting that to a scoped_restore. However,
prepare_for_detach wants to discard the cleanup on success, and
scoped_restore doesn't have an equivalent for that. So I added one --
I called it "release()" because it seems like a natural fit in the way
standard components call similarly-spirited methods, and, it's also
what the proposal for a generic scope guard calls it too, AFAICS:
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2014/n4189.pdf

gdb_xml_parser: make data fields private and make more functions methods
This patch makes the data fields of gdb_xml_parser private, and makes
more functions be gdb_xml_parser methods. This is mostly for better
encapsulation.
Some free functions have their parsing-related guts converted to
methods, while the free functions remain, as they're used as expat
callbacks. Now their only job is to be small shims that restore back
the gdb_xml_parser type, defer work to the corresponding method, and
make sure C++ exceptions don't cross expat.
More C++-fycation of the XML parsers built on top of gdb_xml_parser
could follow, but this was my stopping point.

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.

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.

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.

C++-ify gdb/xml-support.c a bit to eliminate cleanups
Basically convert cleanups to destructors in gdb_xml_parser and

make_cleanup calls already.
