d05a8b8c46 Python: Remove getAnArg in DataFlow::CallCfgNode
Until we've had further discussion on what is the right approach to
naming (internal discussion in https://github.com/github/codeql-python-team/issues/95)

af644a0adb Python: Decrease import depth in regex tests
These were increased because of the indirection needed to get to the
regex flags, but as we no longer rely on this, we can make do with a
smaller import depth.

5bb4a1a45a Python: Use explicit argument specification instead of getAnArg
I've seen quite a few places where `getAnArg` leads to wrong behavior, and I
generally just don't like it.

e812eb777d Python: Port URL sanitisation queries to API graphs
Really, this boils down to "Port `re` library model to use API graphs
instead of points-to", which is what this PR actually does.

Instead of using points-to to track flags, we use a type tracker. To
handle multiple flags at the same time, we add additional flow from

`x` to `x | y` and `y | x`

and, as an added bonus, the above with `+` instead of `|`, neatly
fixing https://github.com/github/codeql/issues/4707

I had to modify the `Qualified.ql` test slightly, as it now had a
result stemming from the standard library (in `warnings.py`) that
points-to previously ignored.

It might be possible to implement this as a type tracker on
`LocalSourceNode`s, but with the added steps for the above operations,
this was not obvious to me, and so I opted for the simpler
"`smallstep`" variant.

42de872bfa Python: Add INTERNAL annotation to Response::InstanceSource
Since we need to reserve the flexibility to change this setup within the next

the 12 months that the normal API deprecation cycle requires.

Although it is becoming non-trivial to get an overview of what tests we have and

I used all 3 variants of parameters, just to be sure :)

0e9a54e9a9 Python: Rename WeakCrypto to WeakCryptoKey
Since WeakCrypto always makes me think that it's about all weak crypto (like
using MD5, or completely broken ciphers such as ARC4 ro DES) and not just about
weak key generation.

46ad611d57 Python: Port py/weak-crypto-key to use type-tracking
instead of points-to.

Looking at query results also made me realize I didn't supply a very good
"origin" for ECC in cryptography package, so I improved that 👍 -- maybe that
sohuld have been split into multiple commits... too late :(
