Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__

Issue #3657: Fix uninitialized memory read when pickling longs.
The conversion to the unicode API was incorrect, it should use bytes.
repr is a bad variable name. The use is overloaded, but I'll leave
that to fix later.
Fix:
* crashes on memory allocation failure found with failmalloc
* memory leaks found with valgrind
* compiler warnings in opt mode which would lead to invalid memory reads
* problem using wrong name in decimal module reported by pychecker
Update the valgrind suppressions file with new leaks that are small/one-time
leaks we don't care about (ie, they are too hard to fix).

Since we are closing the fileno anyway, the best is to skip this part.

dropped mention of re.LOCALE in most places since it is not recommended.

- Issue #3300: make urllib.parse.[un]quote() default to UTF-8.
Code contributed by Matt Giuca. quote() now encodes the input
before quoting, unquote() decodes after unquoting. There are
new arguments to change the encoding and errors settings.
There are also new APIs to skip the encode/decode steps.
[un]quote_plus() are also affected.
Optimization of str.format() for cases with str, unicode, int, long,
and float arguments. This gives about 30% speed improvement for the
simplest (but most common) cases. This patch skips the __format__
dispatch, and also avoids creating an object to hold the format_spec.
Unfortunately there's a complication in 2.6 with int, long, and float
because they always expect str format_specs. So in the unicode
version of this optimization, just check for unicode objects. int,
float, long, and str can be added later, if needed.
