* chart labels for alerts
* proper termination
* use strchr
* change if statement
* change label variable. add docs
* change doc
* assign buf to temp
* use new dictionary functions
* reduce variable scope
* reduce line length
* make sure rrdcalc updates labels after inserted
* reduce var scope
* add rrdcalc.c for cmocka tests
* Revert "add rrdcalc.c for cmocka tests"
This reverts commit 5fe122adcf
.
* Fix cmocka unit tests
* valgrind errors
