Added WindowsError to compatibility mappings.

Fixed ambigious reverse mappings.  Added many new mappings.  Import mapping
is no longer applied to modules already mapped with full name mapping.

Added tests for compatible pickling and unpickling and for consistency of
_compat_pickle mappings.

The previous patch only dealt with KeyboardInterrupt when all of the
data had been consumed by the pager.  This deals with the interrupt
when some data is still pending.

MemoryError.

This mimics get_param's error handling for the most part.  It is slightly
better in some regards as get_param can produce some really weird results for
duplicate *0* parts.  It departs from get_param slightly in that if we have a
mix of non-extended and extended pieces for the same parameter name, the new
parser assumes they were all supposed to be extended and concatenates all the
values, whereas get_param always picks the non-extended parameter value.  All
of this error recovery is pretty much arbitrary decisions...

directories are left after running a test.

Previously, if you hit ctl-c while the pager was active, the python that
launched the subprocess for the pager would see the KeyboardInterrupt in the
__exit__ method of the subprocess context manager where it was waiting for the
subprocess to complete, ending the wait.  This would leave the pager running,
while the interactive interpreter, after handling the exception by printing
it, would go back to trying to post a prompt...but the pager would generally
have the terminal in raw mode, and in any case would be still trying to read
from stdin.  On some systems, even exiting python at that point would not
restore the terminal mode.  The problem with raw mode could also happen if
ctl-C was hit when pydoc was called from the shell command line and the pager
was active.

Instead, we now wait on the subprocess in a loop, ignoring KeyboardInterrupt
just like the pager does, until the pager actually exits.

(Note: this was a regression relative to python2...in python2 the pager
is called via system, and system does not return until the pager exits.)

-Og does not optimize the C code, it's just "fast debugging".

Flushing sys.stdout and sys.stderr in Py_FatalError() can call again
Py_FatalError(). Add a reentrant flag to detect this case and just abort at the
second call.
