[SSSD] [PATCH] Consolidation of functions that make realm upper-case

[Ondrej Kos]

https://fedorahosted.org/sssd/ticket/1491

I prepared function *get_uppercase_realm* accessible through 
src/util/util.h which returns uppercase realm string. If whole principal 
is passed, it transforms only the part after '@' character. Multiple 
uses of *toupper* have been replaced and modified to use mentioned new 
function.
