Tom Tromey c819b2c0b2 C++-ify typedef hash
This changes the typedef_hash_table structure to be a C++ class.  It
adds constructors and destructors and changes some functions to be
methods of the class.  Then it changes the various users of this class
to adapt.  This allows for the removal of some cleanups.

Regression tested by the buildbot.

Tom Tromey 63283d4a29 Remove EXT_LANG_BT_COMPLETED
While looking at the frame filter code, I noticed that
EXT_LANG_BT_COMPLETED is not really needed.  Semantically there is no
difference between the "completed" and "ok" results.  So, this patch
removes this constant.

Tom Tromey 978d6c756f Allow hiding of some filtered frames
When a frame filter elides some frames, they are still printed by

Tom Tromey 6893c19a8b Make "bt N" print correct number of frames when using a frame filter
PR python/16497 notes that using "bt" with a positive argument prints
the wrong number of frames when a frame filter is in use.  Also, in this
case, the non-frame-filter path will print a message about "More stack
frames" when there are more; but this is not done in the frame-filter
case.

The first problem is that backtrace_command_1 passes the wrong value
to apply_ext_lang_frame_filter -- that function takes the final
frame's number as an argument, but backtrace_command_1 passes the
count, which is off by one.

The solution to the second problem is to have the C stack-printing
code stop at the correct number of frames and then print the message.

Tested using the buildbot.

Simon Marchi f979c73fd0 Remove xmethod_worker::clone
I think that the clone method of xmethod_worker can be removed.  It is
only used in find_overload_match, to clone an xmethod we want to
keep.  Instead, we can just std::move it out of the vector and into
value_from_xmethod.  value_from_xmethod creates a value that will own
the xmethod_worker from that point.  Other xmethod_workers left in the
vector will get destroyed when the vector gets destroyed, but the chosen
one will keep living inside the value struct.

	* extension.h (struct xmethod_worker) <clone>: Remove.
	* python/py-xmethods.c (struct python_xmethod_worker) <clone>:
	Remove.
	(python_xmethod_worker::clone): Remove.
	* valops.c (find_overload_match): Use std::move instead of
	clone.

Simon Marchi ba18742c3a C++ify xmethod_worker, get rid of VEC(xmethod_worker_ptr)
The initial goal of this patch was to remove the usage of
VEC(xmethod_worker_ptr) and corresponding cleanups.  I ended up having
to  C++ify the xmethod_worker code, to be able to have xmethod_workers
free their data in destructors, and therefore be able to use vectors of
xmethod_worker unique_ptr.

The operations in extension_language_ops that act on one instance of
xmethod_worker (get result type, get args type, invoke) are transformed
to methods of xmethod_worker.  xmethod_worker becomes an abstract base
class with virtual pure methods which python_xmethod_worker implements.
The only xmethod-related operation left in extension_language_ops is
get_matching_xmethod_workers, which returns a list of xmethod_workers.

The changes are relatively straightforward, but here are some notes on
things that may raise eyebrows:

  - I was not really comfortable with the value_of_xmethod function.  At
  first it looks like a simple getter, so I considered making it a
  method of xmethod_worker.  But actually it creates a value and
  transfers the ownership of the xmethod_worker to it.  It would be a
  bit weird and error-prone if calling a method on an object silently
  removed the ownership of the object from the caller.  To reflect the
  behavior more accurately, I renamed it to value_from_xmethod and made
  it accept an rvalue-reference (so the caller knows it gives away the
  ownership).  I noticed the backlink from xmethod_worker to its owning
  value was not used, so I removed it.

  - Some code, like get_matching_xmethod_workers, made each callee fill
  a new vector, which was then merged in the result vector.  I think
  it's safe if we always pass the same vector around, and each
  implementation just appends to it.

  - The clone operation does not seem particularly useful, it is removed
  in the following patch.
