resolve crashes with ICU 53.1 in locales with collator data, fdo#77071
ICU 53.1 changed API behavior: https://ssl.icu-project.org/apiref/icu4c/classicu_1_1RuleBasedCollator.html#a2f4c7eeaf020ad68e3bd9722dd272357 isn't correct anymore: length: size of the image. If negative, the API will try to figure out the length of the image NO, IT WILL NOT! It bails out with an error instead. Introduced a function to obtain the length for each collator data. base: collator, usually root. The base is required to be present through the lifetime of the collator. Currently it cannot be NULL. NOT "usually root"! There's a check now that bails out if if(base->tailoring != CollationRoot::getRoot(errorCode)) So using an instance created with icu::Locale::getRoot() Change-Id: Ia9c4e27d5ef4f8083bbe57e4e2f4b3ff63bb42ed
