Fix for Bug #466, http://bugs.skysql.com/show_bug.cgi?id=466

Browse Source 
hintparser.c:hint_parser:when string token is found, create a copy of the token value instead of copying the its address because token will be freed before the value is used.
	hint_next_token:didn't recognize '=' as TOK_EQUAL, fixed that. Read the code.
hint.c:hint_create_parameter: copy the pointer to parameter name instead of creating copy of it - pname is already copied from token before the call
readwritesplit.c:routeQuery:Hint name was copied when hint value was supposed to be copied, thus resulting invalid value for hinted parameter. Also fixed server type in trace log command.
skygw_debug.h:Added string for Relay server to macro STRSRVSTATUS.
