Bug#22645 LC_TIME_NAMES: Statement not replicated

Problem: replication of LC_TIME_NAMES didn't work.
Thus, INSERTS or UPDATES using date_format() always
worked with en_US on the slave side.
Fix: adding ONE_SHOT implementation for LC_TIME_NAMES.


mysql-test/r/variables.result:
  Adding various tests with LC_TIME_NAMES and
  string and numeric constants and expressions.
mysql-test/t/variables.test:
  Adding various tests with LC_TIME_NAMES and
  string and numeric constants and expressions.
sql/log.cc:
  Adding ONE_SHOT trick for lc_time_names.
sql/mysql_priv.h:
  Adding new member "number" - for unique locale IDs.
  Adding prototype for my_locale_by_number().
sql/set_var.cc:
  Modifying lc_time_names variable to understand both:
  - string valyes (using locale name)
  - number values (using locale IDs)
sql/set_var.h:
  - Marking lc_time_names as ONE_SHOT capable.
  - Marking lc_time_names as INT_RESULT compatible.
sql/sql_locale.cc:
  - adding local IDs
  - better layout for locale data declarations
    (splitting long lines into short ones)
  - adding DBUG_ASSERT into my_locale_by_name()
    and moving this function towards the end of file -
    after "my_locales" declaration
  - adding my_locale_by_number() implementation
sql/sql_parse.cc:
  Adding initialization of lc_time_names
  to its default value (en_US)
mysql-test/r/rpl_locale.result:
  Adding test case
mysql-test/t/rpl_locale.test:
  Adding test case
