Add privacy feature: APIs and privacy info

To Test New APIs, bulid packages and install tc-privilege-checker.*.rpm and run /usr/bin/tc-privilege-info

For using new APIs:
#include <privilege_info.h>

int ret = privilege_info_is_privacy("http://tizen.org/privilege/account.read");
if (ret == 1)
    //is privacy case
else if (ret == 0)
    // is not privacy case
else if (ret == -1)
    // on error

GList* privacy_list = NULL; // privacy_list must be released with g_list_free by caller
ret = privilege_info_get_privacy_list(&privacy_list);
if (ret == 0) // ret == PRVMGR_ERR_NONE
    // success case
else
    // on error

GList* privilege_list = NULL; // privilege_list must be released with g_list_free by caller
ret = privilege_info_get_privilege_list_by_privacy("ACCOUNT", &privilege_list);
if (ret == 0) // ret == PRVMGR_ERR_NONE
    //success case
else if (ret == PRVMGR_ERR_INVALID_PARAMETER)
    // privacy param is NULL
else
    // on error
