This patch speeds up the charmap encoder by a factor of 4 to 5, using a
trie structure instead of a dictionary; the speedup primarily comes from
not creating integer objects in the process.
The trie is created by inverting the encoding map; the codec generator is
changed to drop the encoding dictionary, and instead emit a function call
to create the trie.

Updated the patch as part of NeedForSpeed
(mainly Py_ssize_t changes and some rejected chunks)
Because the previous version on the trunk was
broken I'm not sure what to compare the results against ;)

Hi Martin,
I've only had a quick look at the patch, but it looks nice,
so please check it in.
Don't we also have to regenerate all the codecs once this
patch has been applied ?! If so, I can take care of that
using Makefile approach in Tools/unicode/. Please let me know.
Thanks.

Thanks for all comments and reviews; I have now committed
the patch as r46648. This includes a regeneration of the
individual codecs.
