Mention two more bugfixes. Not the initial Go 1.17 support just yet,
because coincidentally it broke in the past 24h due to upstream changes.
Also tweak some of the other wording to be clearer.
First, write a changelog file. We will use GitHub releases, but the
content in those is not stored in git nor is it portable or machine
readable. The canonical place for the changelog is here.
Second, disable 'garble test', as it is entirely broken. Issue #241
tracks fixing and re-enabling it, which will most likely happen for the
next release.
Third, disable the undocumented 'garble list'. This was added as part of
'garble reverse', but it never got used. I can't think of any reason why
any end user would prefer it over 'go list', either.
'garble reverse' remains enabled, but undocumented as it isn't fully
functional yet. Until it supports position information, it's not
particularly useful to end users. But it's not broken either, so it can
remain where it is.
Fourth, update the '-tiny' size reduction numbers in the README. Since
we removed the in-place modification of object files, we are no longer
able to do such an aggressive stripping of info. Garble itself drops in
size by 2%, so replace the old 6-10% estimate by 2-5%. We probably will
gain some of this back in the near future.
Finally, fix the indentation formatting of the README to consistently
use tabs.
