* git_id updated to generate revision_sql.h file with required_* fields strings.
* mangosd/realmd changed to include header and check this strings at startup.
* mangosd/realmd will terminated if related strings not match in DB content.
In most cases this meaning that not all expected sql updates applied.
Current required_* field stored in DB output in error to help find what last sql updates applied.
IMPORTNAT NOTE for mangos devs: please update used git_id before adding next commits with sql updates!
