Ref T7152. Ref T1139. This is a little far afield, but I need to translate some "%s thing(s)" strings into English in Instances to complete the invite workflow.
This isn't currently possible because translations are not modular enough: a library can not translate only its own strings.
To fix this:
- Define PhutilLocale, which provides a target translation language, like "English (US)".
- Provide PhutilTranslation, which provides some strings in a target language. Libraries can subclass PhutilTranslation to supplement strings.
- Rework PhutilTranslator to be aware of locales.
- I also formalized test translations, silly translations, and de-hacked up the "ALL CAPS" translation. The sex/plural rules are still hard-coded for now.
