replace guint by gsize for the glib2 version of irssi_ssl_read

Browse source 
like it's defined in GIOFuncs for glib2
moved src/fe-text/utf8.* to src/fe-common/core
changed get_utf8_char so it returns a status code and the unichar argument pointer
to the value that it returned before if there were no errors,
so you can check for a negative value an handle the error
