Remove Halt from Kernel

[jecisc]

I propose as a first step to move Halt from Kernel and put it in Debugging-Core.

Imagine, for a moment, that you came upon a bread factory for the first time. At first it just looks like a jumble of incomprehensible machinery with a few people buzzing around. As your eyes adjus…

Halt seems deeply intertwined with the kernel.
Its removal from Context >> runUntilErrorOrReturnFrom: introduced a regression with a problem stepping-over "self halt" in the debugger, fixed here... #5289

Perhaps the class itself can remain but be slimmed down to move the majority of code to Debugging extensions that live outside the Kernel ?

@MarcusDenker what do you think about this issue?
@jecisc could you explain why removing halt from the kernel?

Should we close this issue?

One of Pharo's goal is to be more modular and to have the smallest core possible for the bootstrap.

Halt is a debugging utility. Kernel does not need it and it can be loaded during a later step of the bootstrap probably.

Thanks Cyril, I understand.
I remove debugger tags from this issue, as it is more related to modularity and not to the debugger and debugging system themselves.
