[8441] Implement check DBs versions (required_* fields) at mangosd/realmd loading.

Browse source 
* 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!
