Bug#37575 UCASE fails on monthname

The MONTHNAME/DAYNAME functions
returns binary string, so the LOWER/UPPER functions
are not effective on the result of MONTHNAME/DAYNAME call.  
Character set of the MONTHNAME/DAYNAME function
result has been changed to connection character set.


include/m_ctype.h:
  added my_charset_repertoire function
mysql-test/r/ctype_ucs.result:
  test result
mysql-test/r/func_time.result:
  test result
mysql-test/t/ctype_ucs.test:
  test case
mysql-test/t/func_time.test:
  test case
sql/item_timefunc.cc:
  Item_func_monthname::fix_length_and_dec and
  Item_func_dayname::fix_length_and_dec methods have been
  modified to use connection character set
sql/item_timefunc.h:
  Item_func_monthname::fix_length_and_dec and
  Item_func_dayname::fix_length_and_dec methods have been
  modified to use connection character set
sql/mysql_priv.h:
  added max_month_name_length, max_day_name_length fields into MY_LOCALE struct
sql/mysqld.cc:
  The test_lc_time_sz function controls modifications
  of the locale database in debugging mode.
sql/sql_locale.cc:
  initialization of max_month_name_length, max_day_name_length fields
strings/ctype.c:
  added my_charset_repertoire function
