Update config.guess for all R packages

[Flamefire]

Factor out the check and obtain config.guess from ConfigureMake into free functions to be able to use them inside the rpackage EB.
Change the workflow for R packages to always extract which is more in line with the regular workflow for other EasyConfigs.
This then allows to search for config.guess files to replace by the downloaded version contained within EasyBuild.

This is an alternate, more complete approach to #1938

I tested some random R based ECs including the underlying R successfully: rgdal-1.4-8-foss-2019b-R-3.6.2.eb ncdf4-1.16.1-foss-2019a-R-3.6.0.eb lavaan-0.6-4.1433-foss-2019a-R-3.6.0.eb

Requires:

• Optionally call log.warning in print_warning easybuild-framework#3195

I've tried testing this, but there are too many things in the way. E.g. we need easybuilders/easybuild-easyconfigs#9694 merging. Also older R version have checksum failures (as expected) and I'm not able to go through and fix them right now.

Saying that, it does seem to work for the bits that did build!

@boegel Updated this with the following changes worth verifying:

• Use logger (same for check and obtain function)
• Verify existing file before using it (this avoids a cached config.guess to fail the build if it is an old one, see the removed comment about invalidating the cache which is kinda impossible from the EB side)
• Verify downloaded file through check_config_guess
• Honor force_download build option
• downgrade the print_warning to a log.warning again, but use print_warning in obtain_config_guess when download or verification fails. Otherwise the build output has a few warnings which are not really warnings because the file will be replaced later. I'd actually downgrade the warnings to info in check_config_guess if you agree

Pending approval: Remove arguments of obtain_config_guess. No EasyBlock uses them and Easyblock.obtain_file doesn't have those either. Also the final download location is pretty much opaque to the caller (appended with e.g. EB version) so it doesn't make sense to pass it

@boegel Test results in easybuilders/easybuild-easyconfigs#9830 show that this works and fixes the issue on Power.

What I like to do before merging this is to remove arguments of obtain_config_guess, see #1949 (comment)
This does not change behavior but makes things easier to maintain

I did the change I proposed now for easier assesment in 8af677b I even found that using the source-* argument didn't work at all which is another point for the change.

The current implementation is to raise an error that those arguments were removed. This caters for external users using that function. The alternative is to simply remove the arguments and let Python handle it by throwing a (IIRC) TypeError on unknown/unexpected arguments. But I guess the current implementation is more in line with EB handling such things.

Not using deprecation on purpose as the implementation contained at least 1 bug. So removing it is safer IMO.

@boegel ping again. This has been tested successfully in easybuilders/easybuild-easyconfigs#10531 multiple times.

I've tested this extensively by installing R-4.0.0-foss-2020a.eb, R-3.6.3-foss-2020a.eb and R-3.4.3-foss-2017b-X11-20171023.eb using this enhanced RPackage + a whole bunch of dependencies usingConfigureMake, no problems encountered, so this is good to go...
