Remove deprecated function (#14388) Th second function BdbQuit_IPython_excepthook is wrong anyway as when we moved from warning to error we did not remove stacklevel= ... which is invalid.

Reify colors from debugger.

Cache debugger skip frame predicate (#14386) I'm not 100% sure this is correct as technically the value of __debugger_skip__ could change in the current frame while we are stepping into it, but that is likely super rare, and the slowdown that this create is problematic. There is still a small overhead for me, but this should make the experience much better. See https://github.com/spyder-ide/spyder-kernels/pull/458, https://github.com/ipython/ipython/issues/13972, https://github.com/spyder-ide/spyder/issues/20571, https://github.com/ipython/ipython/issues/14382

Remove link to non-existent ipyparallel docs. (#14383) Those were likely recently removed.
