Make native gdbserver boards no longer be "remote" (in DejaGnu terms)
This commit finally clears the "isremote" flag in the native-gdbserver
and native-stdio-gdbserver boards. The goal is to make all "native"
boards be considered not remote in DejaGnu terms, like the
native-extended-gdbserver board is too.
DejaGnu automatically considers boards remote if their names don't
match the local hostname. That means that native-gdbserver and
native-extended-gdbserver are considered remote by default by DejaGnu,
even though they run locally. native-extended-gdbserver, however,
overrides its isremote flag to force it to be not remote. So we are
in that weird state where native-gdbserver is considered remote, and
native-extended-gdbserver is considered not remote.
A recent set of commits fixed all the problems (and some more) exposed
by testing with --target_board=native-gdbserver and
--target_board=native-stdio-gdbserver with isremote forced off on
x86-64 GNU/Linux. I believe we're good to go now.
The native-stdio-gdbserver.exp/remote-stdio-gdbserver.exp boards
required deep non-obvious modifications unfortunately... The problem
is that if a board is not remote, then DejaGnu doesn't call
${board}_spawn / ${board}_exec at all, and the
native-stdio-gdbserver.exp board relies on those procedures being
called. To fix that, this commit redesigns how the stdio boards hook
into the testing framework to spawn gdbserver. IMO, this is a good
change anyway, because the way its done currently is a bit of a hack,
and the result turns out to be simpler, even. With this commit, they
now no longer load the "gdbserver" generic config, and hook at the
mi_gdb_target_load/gdb_reload level instead, making them more like
traditional board files.
To share code between native-stdio-gdbserver.exp and
remote-stdio-gdbserver.exp, a new shared stdio-gdbserver-base.exp file
is created.
Instead of having each native board clear isremote manually, boards
source the new "local-board.exp" file.
This also adds a new section to testsuite/README file discussing
local/remote/native, so that we can easily refer to it.

ELF: Call check_relocs after opening all inputs
For all ELF targers, call check_relocs after opening all inputs and
garbage collection. Since the symbol resolution is known, check_relocs
can be simplified. Also garbage collection doesn't need to undo what
check_relocs has done for symbols which have been garbage collected.
Since ELF targets never see the removed sections, gc_sweep_hook can be
removed from elf_backend_data and we can avoid GOT/PLT with garbage
collection now.
Set link_info.check_relocs_after_open_input to TRUE for all linker
targets which use ELF linker and update garbage collection tests to
remove unused GOT section.
ldemul_after_check_relocs is added for powerpc to support --secure-plt,

gdbserver: use std::list for all_threads
Remove the usage of inferior_list for the all_threads list in
gdbserver. The entry field in thread_info is removed, and replaced by a
simple ptid field.
I added some functions to iterate (for_each_thread) and find threads
(find_thread). However, changing all the users of find_inferior & co to
use these new functions would have made the patch way too big. So I
opted instead to make find_inferior & co some shims, so that the
existing code only needs to be updated minimally. We can then update
the existing code to use the new functions incrementally (I've started
to do the work, but I'll post it afterwards, see [1] if you want a peek).
This patch has been built-tested on all relevant platforms, except
lynx. I also regtested using the native-gdbserver and
native-extended-gdbserver boards on x86.

gdbserver: Use std::list for all_dlls
As a small step towards removing inferior_list/inferior_list_entry, this
patch replaces the usage of inferior_list for the list of dlls by an
std::list. The dll_info type now uses an std::string for name and has a
simple constructor.

Make to_traceframe_info return a unique_ptr
Since this target method returns an allocated object, return a
unique_ptr. It allows getting rid a some cleanups here and there.
I had to shuffle the includes around. First, target.h now needs to
include tracepoint.h, to get the definition of traceframe_info_up.
However, the definition of enum trace_find_type was later in target, so
I had to move it to tracepoint.h, so that the declaration of tfind_1
could know about it. I then had to remove the include of target.h from
tracepoint.h, which caused a circular dependency (it was probably
included to get enum trace_find_type in the first place anyway).
Regression tested on the buildbot.

FT32: support for FT32B processor - part 1
FT32B is a new FT32 family member. It has a code
compression scheme, which requires the use of linker
relaxations. The change is quite large, so submission
is in several parts.
Part 1 adds a 15-bit instruction field, and CPU-specific functions for
the code compression that are used in binutils and GDB.

Eliminate is_remote check in gdb.base/scope.exp
This commit makes --target_board=native-gdbserver (and in principle
all other is_remote boards) pass all the same gdb.base/scope.exp tests
as native testing.
I first wrote the gdb.base/scope.exp change described in the ChangeLog
below and in the new comments in the patch, knowing that gdb_file_cmd
was the right thing to use here.
However, that revealed that the native-extended-gdbserver board should
be overriding gdb_file_cmd+gdb_reload instead of gdb_load, as is
hinted at by the comments on top of the default implementations in
testsuite/lib/gdb.exp, because otherwise a gdb_run_cmd after
gdb_file_cmd misses setting "set remote exec-file". However, if we do
that and remove gdb_load, then we regress gdb.base/dbx.exp, so for now
keep the gdb_load override as well.

Make gdb.base/auvx.exp work with --target_board=native-extended-gdbserver
Currently we get:
Running .../src/gdb/testsuite/gdb.base/auxv.exp ...
WARNING: can't generate a core file - core tests suppressed - check ulimit -c
After this commit we get all the same PASSes as when native testing.
The problem is that the testcase wants to create a core dump in a
temporary directory and it is using the "cd" command to start the
inferior with that directory as current directory, but that command
only affects the inferior's cwd when native debugging. Fix it by
using using the new "set cwd" command instead, which works with
gdbserver as well.
This still won't work with stub-like targets, because with those when
we connect the inferior is already running. It'd be possible to make
it work by making the inferior itself change dirs, but we'll need to
make the native-gdbserver board no longer set is_remote first.

lwp_info: Make the arch code free arch_lwp_info
I have the goal of "poisoning" the XNEW/xfree-family of functions, so
that we catch their usages with non-POD types. A few things need to be
fixed in the mean time, this is one.
The common lwp code in linux-nat.c and gdbserver/linux-low.c xfrees the
private lwp data of type arch_lwp_info. However, that type is opaque
from its point of view, as its defined differently in each arch-specific
implementation. This trips on the std::is_pod<T> check, since the
compiler can't tell whether the type is POD or not if it doesn't know
about it.
My initial patch [1] made a class hierarchy with a virtual destructor.
However, as Pedro pointed out, we only have one native architecture at
the time built in gdb and gdbserver, so that's overkill. Instead, we
can move the responsibility of free'ing arch_lwp_info to the arch code
(which is also the one that allocated it in the first place). This is
what this patch does.
Also, I had the concern that if we wanted to use C++ features in these
structures, we would have a problem with the one-definition rule.
However, since a build will only have one version of arch_lwp_info,
that's not a problem.
There are changes in arch-specific files, I was only able to built-test
this patch with the following cross-compilers:
aarch64-linux-gnu
alpha-linux-gnu
arm-linux-gnueabihf
hppa-linux-gnu

Set dynamic_undefined_weak to zero for static PIEs
I believe we should be warning if ld is given both --no-dynamic-linker
and -z dynamic-undefined-weak. The two options are contradictory, the
first says an executable has no dynamic interpreter to resolve dynamic
symbols, while the second is asking for dynamic symbols to be emitted.
(And even if a static PIE's relocation code, which is needed to
process R_*_RELATIVE relocs, could process symbols, there are no
DT_NEEDED dynamic objects to define such symbols.)
I also think that dynamic_undefined_weak is the right flag to control
whether undefined weaks are made dynamic, whether in static PIEs or
anywhere else. So force it to 0 for static PIEs, fixing PR 22269 for
powerpc and any other target where the backend usually defaults to
undefined weaks being made dynamic.
This patch introduces regressions. I'd normally not do that, but
these are all in very recently added test cases, or expose bugs in the
x86 backend. The test cases were added after I'd made it known that
this patch or one like it was imminent.

Constify add_prefix_cmd
This changes add_prefix_cmd to accept a const-taking function as an
argument; then fixes up all the callers.
In a couple of spots I had to add a non-const overload of a function,
because the function is passed to two different command-adding
"constructors". These overloads are temporary; once constification is
complete they can be removed.
This patch also fixes a typo I happened to notice while constifying.
Note that this touches a couple of files (gnu-nat.c and go32-nat.c)
that I can't build. So, while I made a best-effort there, I am not
certain they will still compile.
Tested by rebuilding.
