adodbapi: Cleanup obsolete and unsupported python code

[Avasam]

Following a general understanding that adodbapi code changes will be a lot harder to test, and comments in #1990, these changes have been completely split off. With the final goal to make basic type-checking validation of public methods possible, easing the addition of 3.7+ type annotations. I am fine if that excludes adodbapi.

A handful of PRs listed below have overlapping or extracted changes. I'd recommend reviewing those first, in the mean time I'm marking this PR as draft.

This cleans-up most unreachable code. Mostly due to unsupported python versions.

• Remove Python2 specific code
  • Update Python3/Python2 specific comments
  • Added a TODO to the comments that mentioned python 2/3 specific code. But that I didn't know how to address.
  • Replaced use of deprecated Types
  • adodbapi.remote adodbapi: Remove outdated and unused remote feature #2098
  • Obsolete and redundant aliases adodbapi: Remove obsolete aliases #2088
  • Redundant object subclassing adodbapi: Remove redundant object subclassing #2086
  • IronPython adodbapi: Remove references to outdated IronPython #2049
  • mxDateTime adodbapi: Remove references to outdated mxDateTime #2048
• Simplify simple functions by using assignments: Simplify simple functions by using assignments #2214
• Explicit re-exports to keep some backward compatibility
• Update platform/version checks
• Removed unreachable code

The simplest answer here would be to delete the entire "remote" directory. I don't think that the facility has ever been used by anyone other than myself, and the use case for that is now very outdated. I am in favor of dropping the entire subsystem as deprecated.

Yes, adodbapi/remote.py should be removed also.

A quick search I didn't find any reference to the remote directory either. I did find some to the remote module though, but only in tests. I am in favor of dropping the entire subsystem as deprecated. Do you also mean adodbapi/remote.py ?

Is this just to pull upstream changes into the adodbapi fork?

@vernondcole This is a "too big to review" PR that has been split up into smaller chunks in other PRs. It contains all of the code modernization and old code removal changes at once. Useful for me to reference when there will undoubtedly be merge conflicts, and allows me to test the interaction of different changes in their final combined state.

Hence it's marked as Draft. Once everything else is merged I'll either Publish this PR or keep splitting off what's left in more reviewable chunks.

As per the PR description:

[vernondcole]

Understood.
I am still working on creating a set of VMs so that I can properly test this and get everything merged back in.

@vernondcole This is now in a state ready to be reviewed. The bulk has been extracted in other PRs.
