-DCALL_PROFILE: Count the number of function calls executed.

When this symbol is defined, the ceval mainloop and helper functions
count the number of function calls made.  It keeps detailed statistics
about what kind of object was called and whether the call hit any of
the special fast paths in the code.

Optimization:

When we take the fast_function() path, which seems to be taken for
most function calls, and there is minimal frame setup to do, avoid
call PyEval_EvalCodeEx().  The eval code ex function does a lot of
work to handle keywords args and star args, free variables,
generators, etc.  The inlined version simply allocates the frame and
copies the arguments values into the frame.

The optimization gets a little help from compile.c which adds a
CO_NOFREE flag to code objects that don't have free variables or cell
variables.  This change allows fast_function() to get into the fast
path with fewer tests.

I measure a couple of percent speedup in pystone with this change, but
there's surely more that can be done.

be bothered to fix it.

the code.

For the case where the current globals match the previous frame's
globals, eliminates three tests in two if statements.  For the case
where we just get __builtins__ from a module, eliminate a couple of
tests.

  gzip shouldn't raise ValueError on corrupt files

  Currently the gzip module will raise a ValueError if the file was
  corrupt (bad crc or bad size).  I can't see how that applies to
  reading a corrupt file.  IOError seems better, and it's what code
  will likely be looking for.

file can be dumped without (bogus) complaint if the the pickles were
created using a single pickle memo.

merge_class_dict():  This was missing a decref.

Bugfix candidate.

Added array.array to the types repr.py knows about, after a suggestion
from Jurjen N.E. Bos.

Applied the skip test_ossaudiodev patch.

the clipboard contains a filename that filename is used as the default.

It also prevents building against the real X headers, if installed.

After discussions with the Cygwin project lead, I believe that building
against the real X headers is OK. Especially, since the psuedo-X headers
are *not* installed by the Cygwin Tcl/Tk binary package.

Note that this patch just reverts the lib_prefix (i.e., "cyg") portion
of my Tcl/Tk 8.3 patch. It seems that Cygwin Tcl/Tk is using a more
normal file naming convention again.

we have a symlink somewhere in the TESTFN path.

tests:  Moved ExtensionSaver from test_copy_reg into pickletester, and
use it both places.  Once extension codes get assigned, it won't be
safe to overwrite them willy nilly in test suites, and ExtensionSaver
does a thorough job of undoing any possible damage.

Beefed up the EXT[124] tests a bit, to check the smallest and largest
codes in each opcode's range too.

Moved such EXT tests as currently exist from TempAbstractPickleTests to
AbstractPickleTests, so that test_cpickle runs them too.

str and unicode subclasses not just for generating the output
but for testing too.

so we can jump to the error handling code that does.
(Spotted by Neal Norwitz)

blindly assumed that tp_as_sequence->sq_item always returns
a str or unicode object. This might fail with str or unicode
subclasses.

This patch checks whether the object returned from __getitem__
is a str/unicode object and raises a TypeError if not (and
the filter function returned true).

Furthermore the result for __getitem__ can be more than one
character long, so checks for enough memory have to be done.
