Fix PR python/19438, PR python/18393 - initialize dictionaries
This fixes PR python/19438 and PR python/18393. Both bugs are about
invoking dir() on some Python object implemented by gdb, and getting a
crash.
The crash happens because the dictionary field of these objects was
not initialized. Apparently what happens is that this field can be
lazily initialized by Python when assigning to an attribute; and it
can also be handled ok when using dir() but without __dict__ defined;
but gdb defines __dict__ because this isn't supplied automatically by
Python.
The docs on this seem rather sparse, but this patch works ok.
An alternative might be to lazily create the dictionary in
gdb_py_generic_dict, but I went with this approach because it seemed
more straightforward.
Built and regtested on x86-64 Fedora 23.

MIPS: Fix the encoding of immediates with microMIPS JALX
The microMIPS JALX instruction shares the R_MICROMIPS_26_S1 relocation
with microMIPS J/JAL/JALS instructions, however unlike the latters its
encoded immediate argument is unusually shifted left by 2 rather than 1
in calculating the value used for the operation requested.
We already handle this exception in `mips_elf_calculate_relocation' in
LD, in a scenario where JALX is produced as a result of relaxing JAL for
the purpose of making a cross-mode jump. We also get it right in the
disassembler in `decode_micromips_operand'.
What we don't correctly do however is processing microMIPS JALX produced
by GAS from an assembly source, where a non-zero constant argument or a
symbol reference with a non-zero in-place addend has been used. In this
case the same calculation is made as for microMIPS J/JAL/JALS, causing
the wrong encoding to be produced by GAS on making an object file, and
then again by LD in the final link. The latter in particular causes the
calculation, where the addend fits in the relocatable field, to produce
different final addresses for the same source code depending on whether
REL or RELA relocations are used.
Correct these issues by special-casing microMIPS JALX in the places that
have been previously missed.

gas/arc: Fix array overrun when checking opcode array
The opcode array iterator mechanism can, in some situations, result in
reading memory outside of the opcode array. When using the
iterator-next mechanism to find the next possible arc_opcode, if we find
an opcode where the name field is NULL, or the name does not match, then
the cached opcode pointer is not set to NULL. The result is that
another call to iterator-next will again increment the opcode
pointer (which might now point outside the opcode array) and attempt to
access the name field of this undefined opcode.
Fixed in this commit by clearing the cached opcode pointer.

Add mi-threads-interrupt.exp test (PR 20039)
Add a new test for PR 20039. The test spawns new threads, then tries to
interrupt, continue, and interrupt again. This use case was fixed by
commit
5fe966540d6b748f825774868463003700f0c878 in master, but gdb 7.11
is affected (so if you try it on the gdb-7.11-branch right now, the test
will fail).
New in v2, the test now handles mi-async on mode properly. The failure
was specific to mi-async off, but I don't think it's bad to test the
same thing under async on mode. I added a little hack when running in
async mode to work around bug 20045.

trigger the problem.

Fix double prompt output after run control MI commands with mi-async on (PR 20045)
When you use a run control command (-exec-run, -exec-continue,
-exec-next, ...) with mi-async on, an extra (gdb) prompt is displayed:
-exec-continue
^running
*running,thread-id="all"
(gdb)
(gdb)
It doesn't seem to be a big problem for front-ends, since this behavior
started in gdb 7.9 and we haven't heard anything about that. However,
it caused me some trouble while writing a test for PR 20039 [1].
The problem comes from an extra (gdb) prompt that we write when running
in mi-async off mode to emulate a past buggy behavior. When executing a
run control command synchronously, previous gdbs always printed a prompt
right away, even though they are not ready to accept new MI commands
until the target stops. Only at this time should they display a prompt.
But to keep backwards compatibility apparently, we print it anyway.
Since commit
198297aaf, the condition that decides whether we should
print that "bogus" prompt or not has become true, even when running with
mi-async on. Since we already print a prompt at the end of the
asynchronous command execution, it results in two prompts for one
command.
The proposed fix is to call target_can_async_p instead of
target_is_async_p, to make the condition:
if (!target_can_async_p () || sync_execution)
... show prompt ...
That shows the prompt if we are emulating a synchronous command on top
of an asynchronous target (sync_execution) or if the target simply can't
run asynchronously (!target_can_async_p ()).
Note that this code is changed and this bug fixed by Pedro's separate
console series, but I think it would be nice to have it fixed in the
mean time.
I ran the gdb.mi directory of the testsuite with mi-async on and off, I
didn't see any regressions.

Match shell_prompt # in batch-preserve-term-settings.exp

The perfect solution would be "set_board_info shell_prompt" in the

batch-preserve-term-settings.exp. This is a little bit overkill to
me, and we still need to figure out the different prompts on different
