Subject: *.c: Publish algorithm and crypto-group tables as `mapping' objects.
X-Git-Url: https://git.distorted.org.uk/~mdw/catacomb-python/commitdiff_plain/a539ffb8538158c1dc7eeb4ad5264a6e995496b6?hp=a539ffb8538158c1dc7eeb4ad5264a6e995496b6

*.c: Publish algorithm and crypto-group tables as `mapping' objects.

Previously, the algorithm tables were published as plain Python
dictionaries, and the group tables were published in a complicated way
through a read-only mapping object implemented in Python.

With the richer Python 3 mapping protocol, maintaining a separate custom
mapping object in Python seems much less attractive.  Also, the group
tables were read-only while the algorithm tables were mutable, which was
a rather unfortunate inconsistency.

Fix this mess by implementing a new simple mapping object, based on
Pyke's generic mapping machinery, and populating instances of it with
the necessary data.
