- upgrade to version 0.4.8

docs here are best-guess:  the MS docs I could find weren't clear, and
some even claimed _commit() has no effect on Win32 systems (which is
easily shown to be false just by trying it).

Adding code to handle it properly.

Fix missing right parenthesis.
Add three examples.

but for now, let's get it in and things passing the tests again!

using a build directory just inside the source directory and saving
just one copy of the test data in the source tree, rather than having
a copy in each build directory.

and group names. This should fix SF bug #724771.

* Can now test for basic blocks.
* Optimize inverted comparisions.
* Optimize unary_not followed by a conditional jump.
* Added a new opcode, NOP, to keep code size constant.
* Applied NOP to previous transformations where appropriate.

Note, the NOP would not be necessary if other functions were
added to re-target jump addresses and update the co_lnotab mapping.
That would yield slightly faster and cleaner bytecode at the
expense of optimizer simplicity and of keeping it decoupled
from the line-numbering structure.

  * UINT_MAX -> ULONG_MAX since we are dealing with longs
  * ParseTuple needs &int for 'i' and &long for 'l'
    There may be a better way to do this, but this works.

Remove "." in coverage output for lines with comments.
Silence complaints in coverage output about unexecuted docstrings.

Eliminate use of inspect module in favor of direct access to frame and
code objects.  We're in a trace function here:  Efficiency counts!

Remove unused code.  Reflow long lines.

Remove backwards compatibility for stored trace output from Zooko's
experiment to add calledfuncs to the pickled dict.

Move code to generate per-file coverage stats to a separate routine.

Replace use of parser module with call to compile.

- restructure build for modules now in Python DLL

  from CVS
- reflect move of modules into core DLL
- add section on building from source

- add _csv module to the build list

  * Fixed some long-hidden bugs revealed by the new PyUnit-based
    test suite (thanks to Johannes Gijsbers the new test suite,
    improved tests that caught the bugs, and the bug fixes).

  * Make store_true/store_false store True/False rather than 1/0.

I've applied a modified version of Greg Chapman's patch. I've included
the fixes without introducing the reorganization mentioned, for the sake
of stability. Also, the second fix mentioned in the patch don't fix the
mentioned problem anymore, because of the change introduced by patch
#720991 (by Greg as well). The new fix wasn't complicated though, and is
included as well.

As a note. It seems that there are other places that require the
"protection" of LASTMARK_SAVE()/LASTMARK_RESTORE(), and are just waiting
for someone to find how to break them. Particularly, I belive that every
recursion of SRE_MATCH() should be protected by these macros. I won't
do that right now since I'm not completely sure about this, and we don't
have much time for testing until the next release.
