docs/options-in-versions: which version added each cmdline option

[bagder]

Added test 971 to verify that the list is in sync with the files in
cmdline-opts. The check also verifies that .d-files that uses Added:
specify the same version number as the options-in-versions file does.

[mback2k]

Just FYI: this new test case does not seem to work on Windows yet, but I don't have time to look deeper today.

[Lekensteyn]

The message perl -I. returned 122, when expecting 0 looks somewhat truncated,
though the script does seem to run. My guess is that the regex is too lenient.

Isn't it strange that test 971 now only fails on the windows machines on azure, the other windows jobs work...

[bagder]

BTW: this document lists all currently available options and it is not a representation of all options that ever existed during the project lifetime. This has the effect that for example curl 4.0 (probably) had 21 options but in this list there are only 18 mentioned for 4.0 - this is because three of those early options were subsequently later removed/replaced by other options. This should be kept in mind if you for example compare this data with the dashboard graph that shows a graph of number of cmdline options over time.
