pyke/pyke.[ch]: Make type skeleton structures be read-only.
We couldn't do this before because `INITTYPE_META' would write the
direct superclass to the `tp_base' slot in the skeleton before calling
`inittype'. To make this work, then, we adjust `inittype' to take the
direct superclass as an extra argument and plug it into the newly
created heap-type; and `INITTYPE_META' needs adjusting to pass this
argument rather than trying to write to the skeleton directly.
Of course, then we need to actually mark the type skeletons as `const'.

*.c: Use Python `METH_NOARGS' methods where applicable.
Rather than rolling our own. We need a little extra machinery to insert
the table entries, especially for the generic mapping support, but this
still saves 95 lines of code.

messed things up too badly.

*.c: Make all of the type-definition tables read-only.
The hard part is a new collection of macros which strip the `const'
qualifier from the actual table definitions, after checking that they
actually have the correct type.
And then there's the slog of actually changing all of the definitions
and using the new macros.

pyke/pyke.c: Check conversions hidden inside `KWLIST' and `KWMETH'.
Introduce a new macro `CONVERT_CAREFULLY' which checks (via a rather
sleazy hack) that its operand is of the expected type before converting
it to some other type. This is protected by an `#ifdef' guard because
I'm thinking about adding it to a version of mLib, but I want to keep
the Pyke core independent of mLib.
Use this new macro to build better versions of `KWLIST' and `KWMETH',
which have casts hidden inside them, so that we can now be certain that
the method table entries match up with the functions. (Spoiler: they
didn't, quite, and commit
19bff42f99d41cd9b8953ff61edfe35380b54d88,
backported onto the 1.1.x branch, fixes the bug that was found by this

pyke/pyke.h, key.c: Rename `INDEXERR' to `MAPERR'.
The name `INDEXERR' was pointlessly confusing, given the existing
`IXERR' which actually raises Python's `IndexError'. It's important,
though, that `KEYERR' be reserved for Catacomb's `KeyError' exception,
which really is an error about (cryptographic) keys. So `MAPERR' it is.

The various `KERR_...' constants and `PGEN_ABORT' are canonically
negative integers, but weren't published correctly. Add a flags word to
`struct nameval' to identify constants which should really be signed,
and some fancy footwork to convert unsigned integers back to negative
values without upsetting C. Adjust the `C' macro to spot negative
constants and mark them specially.
Not all is well. In particular, the `KEXP_...' constants should /not/
be published as signed values, even if `time_t' is signed on the target
platform, because the Python bindings handle them exclusively as
`unsigned long' values. To make this work, also introduce `CF' which
allows us to set the flags explicitly, and use it for `KEXP_...'.

catacomb-python.h, *.c: Fix how Python `pgen' handlers handle exceptions.
Oh, this was a mess. The old code would convert an exception from a
Python handler into `PGEN_ABORT', and hope that the exception state was
still available when the overall operation ended.
This doesn't work. In particular, steppers and testers are finalized by
calling them with `PGEN_DONE', and the interpreter doesn't like
re-entering Python with an exception set. (In debug builds, this is an
assertion failure.)
Overhaul all of this nonsense.
* Add a collection of utilities for saving and restoring the exception
state.
* Add a hook, in the `catacomb' module, for reporting `lost'
exceptions, for the case where further exceptions are raised while
responding to a first exception.
* Use a larger `pypgev' structure to track the state of a Python event
handler through the framework. This structure holds a reference to
the Python object itself, and a slot for recording an exception.
* When a Python handler fails, stash the exception state in the slot
provided by the `pypgev' structure if there isn't one already, and
clear the pending exception. If there is already an exception in
the slot, then report the new exception through the hook described
above.
* Once a `pgen' operation completes, if it raised any exceptions at
all, then the first of these is left in the exception slot. If it
fails otherwise, then we supply a generic exception.

* There's a full implementation of the cSHAKE128 and cSHAKE256 XOFs as

* Based on this, there's a full KMAC implementation, with the fiddly
bits in Python (but all the heavy lifting is done in C), with
variable-length tag and everything. Other constructions, e.g.,
TupleHash, can easily be made in the same way.
Annoyingly, KMAC can't just be made from SHAKE by multiple inheritance

objects, and, in particular, which `__new__' methods are OK to use. It
seems that the relevant code is trying to use the `HEAPTYPE' flag as a
proxy for whether a type is implemented in C, which doesn't work for our

Use ValueError instead of SyntaxError throughout.
SyntaxError has a much more specific meaning, and some software, such as
`ipython', expect it to carry lots of other detailed information.
So abolish the `SYNERR' macro, and use `VALERR' instead consistently. I
wish I had an excuse for this blunder, but I don't.

Stamp the module name onto types properly.
Our types are `dynamic', because the Python code adds extra methods to
them. Apparently the correct thing to do in such cases is to put the
raw type name in the `tp_name' slot, and stuff the module name into
`tp_dict' by hand.
