only once (float obviously doesn't set any context at all).

plain tuples to immutable iterable objects with named attributes
(structseq objects).

that was last accessed. In the pi benchmark (64-bit platform, prec=9),
_decimal is now only 1.5x slower than float.

"Refactor" docs for the new dir_fd, follow_symlinks, path-as-fd APIs: document the options at a central place and link to it.

This code passes all the same tests that the existing RFC mime header
parser passes, plus a bunch of additional ones.

There are a couple of commented out tests where there are issues with the
folding.  The folding doesn't normally get invoked for headers parsed from
source, and the cases are marginal anyway (headers with invalid binary data)
so I'm not worried about them, but will fix them after the beta.

There are things that can be done to make this API even more convenient, but I
think this is a solid foundation worth having.  And the parser is a full RFC
parser, so it handles cases that the current parser doesn't.  (There are also
probably cases where it fails when the current parser doesn't, but I haven't
found them yet ;)

Oh, yeah, and there are some really ugly bits in the parser for handling some
'postel' cases that are unfortunately common.

I hope/plan to to eventually refactor a lot of the code in the parser which
should reduce the line count...but there is no escaping the fact that the
error recovery is welter of special cases.

preserve all 64 bits of hash on Win64.

properly skip uncompilable files and to compile existing
files in site-packages if reinstalling.  Also, no longer
attempt to install a documentation link in /Developer
as that no longer necessarily exists with Xcode 4.3+.

We need a discussion to define what should be customized how; this new
config file is premature.  It was added to serve the needs of the
resources system in install_data / packaging.database, so it can be
removed alongside packaging for 3.3.
