skip "attach" tests when testing against stub-like targets
We already skip "attach" tests if the target board is remote, in
dejagnu's sense, as we use TCL's exec to spawn the program on the
build machine. We should also skip these tests if testing with
"target remote" or other stub-like targets where "attach" doesn't make
sense.
Add a helper procedure that centralizes the checks a test that needs
to spawn a program for testing "attach" and make all test files that
use spawn_wait_for_attach check it.

Don't propagate our current terminal state to the inferior
Currently when we start an inferior we have the inferior inherit our
terminal state. Under TUI, our terminal is highly modified by ncurses
and readline. So when starting an inferior under TUI, the inferior will
have a highly modified terminal state which will interfere with standard
I/O. For example,
$ gdb gdb
(gdb) break main
(gdb) run
(gdb) print puts ("a\nb")
a
b
$1 = 4
(gdb) [enter TUI mode]
(gdb) run
(gdb) [exit TUI mode]
(gdb) print puts ("a\nb")
a
b
$2 = 4
(gdb) print puts ("a\r\nb\r")
a
b
$3 = 6
As you can see, when we start the inferior under the regular interface,
puts() prints the text properly. But when we start the inferior under
TUI, puts() does not print the text properly. This is because when we
start the inferior under TUI it inherits our current terminal state
which has been modified by ncurses to, among other things, require an
explicit \r\n to print a new line. As a result the inferior performs
standard I/O in an unexpected way.
Because of this discrepancy, it doesn't seem like a good idea to have
the inferior inherit our _current_ terminal state for it may have been
modified by readline and/or ncurses. Instead, we should have the
inferior inherit a pristine snapshot of our terminal state taken before
readline or ncurses have had a chance to alter it. This enables the
inferior to run in a more accurate way, more closely mimicking the
program's behavior had it run standalone. And it fixes the above
mentioned issue.

Sanitize input_interrupt output
Hi,
This patch is a follow-up of the following discussions:
<https://sourceware.org/ml/gdb-patches/2014-12/msg00421.html>
<https://gcc.gnu.org/ml/gcc-patches/2014-12/msg01293.html>
input_interrupt is currently emiting non-printable characters, which
is confusing the dg-extract-results.sh script. This is obviously not
a good thing, and, by following Pedro's advices here:
<https://gcc.gnu.org/ml/gcc-patches/2014-12/msg01320.html>
I adapted the function to print "client connection closed" when it
receives a NUL character, or use the "isprint" function to decide how
to print the received char. I tested it by running the testcases that
were printing the non-printable chars before:
gdb.base/gdb-sigterm.exp
gdb.threads/non-ldr-exc-1.exp
gdb.threads/non-ldr-exc-2.exp
gdb.threads/non-ldr-exc-3.exp
gdb.threads/non-ldr-exc-4.exp
gdb.threads/thread-execl.exp
and confirming that they print the right message. I tried a bit to
come up with a testcase for this, but failed, and since I did not want
to spend too much time on it, I'm sending the patch anyway.
Comments are welcome, as usual.

AVR: Assembler now prepares for linker relaxation by default.
Have the assembler prepare for linker relaxation by default. This
means that users will be able to make use of linker relaxation without
having to adjust the assembler flags, this can make life easier when
compiling libraries.
Having this on by default in the assembler should make no difference to
the assembler code produced, however, some of the debug information will
be slightly less compressed.
A few tests needed to be updated as a result of this change as they
relied on linker relaxation support being off by default.
I've tightened up the definition of which sections can be relaxed on AVR
as part of this commit, the assembler used to think that all
non-debugging sections could be relaxed, when in reality only code
sections can be relaxed for AVR. The previous definition was not
dangerous, just over cautious. The new tighter definition allows an

Don't create .eh_frame_hdr on shared lib bfd
If no object files have .eh_frame, but some shared library does, then
ld creates a .eh_frame_hdr section using the shared library bfd. This
is silly since shared library .eh_frame sections don't contribute to
the output .eh_frame and thus no .eh_frame_hdr is needed.
Also, the bfd section list and count is cleared for shared libraries,
