lib-charset: Allow plugins to replace charset_* functions They just need to point charset_utf8_vfuncs to their own implementation.

lib-charset: Do not use //IGNORE on non-GNU system

global: freshen copyright git ls-files | xargs perl -p -i -e 's/(\d+)-201[0-5]/$1-2016/g;s/ (201[0-5]) Dovecot/ $1-2016 Dovecot/'

lib-charset: Fixed assert-crash with some iconv() versions. Older glibc iconv() versions seem to skip over invalid characters, at least with some charsets, while newer versions don't. We were assuming that the skipping never happened, so if the invalid character was at the end of the string we could have wrapped size to (size_t)-1 and caused a crash later on.

lib-charset: Added more asserts to checking iconv() results.

lib-charset: Fixed compile warning caused by earlier commit. This UNICODE_REPLACEMENT_CHAR_UTF8 part of the change was actually supposed to be a separate commit..

lib-charset: Added a minimal unit test

lib-charset: Added CHARSET_MAX_PENDING_BUF_SIZE macro and asserts for it.

lib-charset: UTF-8 -> UTF-8 translation was never returning CHARSET_RET_INCOMPLETE_INPUT Instead the incomplete input was just being modified into broken output.

Oops :) Update copyrights to 2013 without breaking all .c files.

Updated copyright notices to include year 2013.

Replaced "decomposed titlecase" conversions with more generic normalizer function. Plugins can now change mail_user.default_normalizer. Specific searches can also use different normalizers by changing mail_search_context.normalizer.

lib-charset: Removed unnecessary buffer size increases, which only caused out-of-memory errors.

lib-charset: Make sure convert_to_utf8*() never returns non-UTF8 output.
