Following methods logs their error message by using hook
error_log_printf(),

  *) my_message_local
  *) my_getopt_error_reporter
  *) my_charset_error_reporter
  *) Query_log_table_intact::report_error
  *) Component_db_intact::report_error
  *) sql_plugin.cc: report_error()

All the error messages logged with these methods get the same
error ID "ER_LOG_PRINTF_MSG".

As part of this WL, changes are made to log those error messages
with the unique error ID.

Error messages are added to errmsg-utf8.txt for the messages
logged using Query_log_table_intact::report_error(),
Component_db_intact::report_error() and sql_plugin.cc:report_error().
Logging API is used to log error messages with the error IDs.

my_message_local, my_getopt_error_reporter, my_charset_error_reporter
are part of the mysys library. mysys library is used by the MySQL
server and clients. Error messages and their ids should be
available to both client and server. Hence these error messages
are added to the global error messages list. In MySQL server,
these methods are logged using the Logging APIs.

This patch also replaces of some the sql_print_error() usage with
the new logging APIs.
