Changed MariaDB error numbers to start from 1900 to not conflict with MySQL error numbers

extra/comp_err.c:
  Allow one to have multiple start-error-numbers in the same error.txt file.
  Generate 'empty' error strings for the missing error numbers in the errmsg.sys file
mysql-test/r/bigint.result:
  Update results to use new error numbers
mysql-test/r/dyncol.result:
  Update results to use new error numbers
mysql-test/r/func_math.result:
  Update results to use new error numbers
mysql-test/r/func_str.result:

mysql-test/r/type_newdecimal.result:
  Update results to use new error numbers
mysql-test/r/warnings.result:
  Update results to use new error numbers
mysql-test/suite/vcol/r/vcol_ins_upd_innodb.result:
  Update results to use new error numbers
mysql-test/suite/vcol/r/vcol_ins_upd_myisam.result:
  Update results to use new error numbers
mysql-test/suite/vcol/r/vcol_misc.result:
  Update results to use new error numbers
sql/derror.cc:
  Ensure we don't read a errmsg.sys with a missing required error message;  This change was needed as errmsg.sys may now contain empty error messages between the MySQL and MariaDB error messages.
  If error message file didn't exist and we have not read one in the past, don't continue.
  Give better error message if the errmsg.sys header has changed.
sql/share/errmsg.txt:
  Create new section, starting from 1900, for MariaDB error messages
