Python object freeing.

PR#175 -- when exec is passed a code object, it didn't sync the locals
from the dictionary back into their fast representation.

Also took the time to remove some repetitive code there and to do the
syncing even when an exception is raised (since a partial effect
should still be synced).

only.  Through some mysterious interaction, they would take 9 separate
arguments as well.  This misfeature is now disabled (to end a
difference with JPython).

previous output.  Call clearerr() to prevent past errors affecting our
ferror() test later, in PyObject_Print().  Suggested by Marc Lemburg.

the 'missing' parameter.

Added 'link_static_lib()' method, and 'archiver' and 'archiver_options'
  class attributes to support it.
Added 'link_executable()' method, and 'ld_exec' instance attribute
  to support it.
'newer_group()' is now able to handle missing files, so we don't have
  to kludge it by catching OSError when calling it.
'object_filenames()' and 'shared_object_filename()' now take 'keep_dir'
  flag parameters.
'library_filename()' and 'shared_library_filename()' now respect
  a directory component in the library name.
Various comment updates/deletions.

Added 'link_executable()' signature.

Added initializer routine optionally to be used as PEF fragment initialization routine, which allows us to get at our own resource fork even if some shared library init routine opens other resource files.

        building the dicts used to inform the user about the defined
        constants when using the *conf*() APIs.

while str() uses %.12g as before.

changed the "method find" algorithm so the function/class/method popup menu also works with space-indented source files -- jvr

                trailing 'L' is appended to the representation,
                otherwise not.

                All existing call sites are modified to pass true for
                addL.

                Remove incorrect statement about external use of this
                function from elsewhere; it's static!

long_str():     Handler for the tp_str slot in the type object.
                Identical to long_repr(), but passes false as the addL
                parameter of long_format().

Converted to Appearance and using a List control in stead of manually creating the List and putting it in a useritem. The old version is in oldPICTbrowse, for documentary purposes.

  handle = Ctl.as_Resource(ctl)
  ctl = Ctl.as_Control(handle)
and similarly for List, Menu, TE. The old handle.as_Control() methods are
still there for backward compatability.

module dict if the inserted object isn't NULL (basic defensive
programming!).

* in import.c, #ifdef out references to dynamic loading based on
  HAVE_DYNAMIC_LOADING

* clean out the platform-specific crud from importdl.c.
  [ maybe fold this function into import.c and drop the importdl.c file? Greg.]

* change GetDynLoadFunc's "funcname" parameter to "shortname". change
  "name" to "fqname" for clarification.

* each GetDynLoadFunc now creates its own funcname value.

  WARNING: as I mentioned previously, we may run into an issue with a
  missing "_" on some platforms. Testing will show this pretty quickly,
  however.

* move pathname munging into dynload_shlib.c

Moved a couple to a new "Not worth it" section (explanations were
already there).

This patch changes the string-based exceptions to class-based
exceptions, so that you can fetch the unknown option as an
attribute.  As far as I know, it is backward compatible.

[The new exception class is called GetoptError; the name error is an
alias for compatibility.]
