Correct "Bengali" language name to "Bangla"

Hello matsbla. I'll take a look at this tomorrow as it is midnight here. Thanks for your work on keeping this issue going.

I have updated the string

In looking at the previous patches and this newest one, I have high degree of confidence that the new patch will pass the rest of the test suite. So I'll pre-emptively mark this as RTBC and if I'm wrong, testbot will downgrade to needs work.

There seems to be something going on here with the test bot. There's no reason why this issue would need to run it's test on the same testbot multiple times. I don't see a way to remove the extra test bots, or at least I haven't found it yet.

Based on https://bugs.launchpad.net/ubuntu/+source/language-selector/+bug/991002 it sounds like this is indeed the correct official name for the language. I am assuming that all language detection and translation is based on the language code, and the provided Bangla name for the language itself is unchanged, so changing its English label should not be disruptive.

I'm undecided on whether this change should be targeted against 8.0.x or 8.1.x at this point. The disruption seems low and it could be considered a bug to use an inaccurate, non-politically-correct name for the language. On the other hand, this does cause a small user interface change in the installer for the language, and since it also has some political implications, I'm leaning toward targeting this fix for 8.1.x. I'll also reach out to the Multilingual initiative lead for his perspective and confirmation.

Drupal works off of web standards as much as possible when dealing with language codes and names. I looked up the language code "bn" with the W3C language tags search tool (http://www.w3.org/International/articles/language-tags/) and that lists this language code as Bengali. Note that that is based on the IANA language tag registry which lists this language as Bengali as well, see http://www.iana.org/assignments/language-subtag-registry/language-subtag.... It does list a language named Bangala under the bxg language code. Not under the bn language code. Then there is the Unicode CLDR registry that also lists language codes (note that we refer to the W3C standards when there is a conflict between CLDR and W3C). In this case the CLDR lists Bengali as well and it does not even list Bangala at all. Drupal works in a larger web ecosystem and the apps needs a shared understanding on which language codes mean which languages. So based on the standards listings, I don't see this would keep Drupal in line with the standards we say we work with.

@Gábor Hojtsy, so in that case are you recommending that this issue needs to be a won't fix?

Well, the W3C sets standards for the web, there needs to be a common understanding between different tools as to what language means what. Even the CLDR lists Bangala under a different language code so if we would jump to conform to CLDR, we'd need to change the language code which comes with all kinds of backwards compatibility nightmares. Why does the CLDR list them as two different languages?

Right, my bad, sorry, misread that :/ It does not change the fact that the CLDR and W3C both disagree with the suggestion of this issue :/ While its true that technically things are identified by language code, if we'd change the label for 'es' to 'Greek', people would be hugely confused given that we mostly only display the label not the language code. In select boxes, admin tables, language selectors, etc. So we are trying to adhere not only to the codes but also the labels.

Also as my misunderstanding showed, even tiny changes in language names mean different languages, so we need to be careful. That is why we try to not go our own path.

I asked in in #multilingual about this. @Gábor Hojtsy replied that the change should be done in code and on localize.d.o.

I've updated the link in the IS to the relevant section of The Constitution of the People‌‌‍’s Republic of Bangladesh.

After doing some reading I've learned that the current entry is correct for the version of the language spoken in India and the language code for it is 'bn-in', So, instead of changing the 'bn' entry to Bangla, should this instead change the existing one to bn-in and add a new one for bn-bd?

Patch #29 tested. working fine. screen shot attached for reference.

@gaurav-mathur, thanks for the interest in this issue. Unfortunately, this patch is not ready for testing. The proposed resolution section of the Issue Summary has not been discussed. To find issue that are ready for testing, I suggest searching the issue queue for issues tagged 'needs manual testing'. Also, check out the contributor tasks on Drupal.org that provide the steps for making useful additions to an issue.

The Needs Review Queue Bot tested this issue. It either no longer applies to Drupal core, or fails the Drupal core commit checks. Therefore, this issue status is now "Needs work".

Apart from a re-roll or rebase, this issue may need more work to address feedback in the issue or MR comments. To progress an issue, incorporate this feedback as part of the process of updating the issue. This helps other contributors to know what is outstanding.
