dovecot 2.2.25 BUG: local_name is not matching correctly

[Arkadiusz Miśkiewicz]

Bug report:

When using dovecot 2.2.25 SNI capability it doesn't always match proper vhost 
config. For example if we have such config:

local_name imap.example.com {
ssl_cert = </etc/certs/cert.imap.example.com.pem
ssl_key = </etc/certs/cert.imap.example.com.pem
}

but imap client sends mixedcase SNI hostname like "IMAP.example.com" then 
dovecot won't match above local_name imap.example.coml config section.

IMO dovecot should do case insensitive comparison. Case sensitive matching for 
DNS names makes little sense.
