"--LOWER_CASE_TABLE_NAMES=1"

Problem:
------
The below tests fail when run with --lower_case_table_names=1 option
    1)rpl.rpl_lcase_tblnames_rewrite_db
    2)rpl.rpl_row_lcase_tblnames
    3)main.lowercase_fs_off
    4)main.mysql_locale_posix

Analysis:
--------
In the two rpl tests listed there are test cases to check whether
creating tables with upper case names on master results in lower case
table names on slave.So the databases/tables on the master should be in
upper-case.
But when these tests are run with --lower_case_table_names=1 the names
are stored lower case and causes result content mismatch failure.

The two main suite tests listed use have_case_sensitive_file_system.inc
file as these tests are specific for case sensitive file systems.
--lower_case_table_names=1 option is not case sensitive.

So for these four tests --lower_case_table_names=1 option is not valid.

Fix:
---
Added "-- source include/have_lowercase0.inc" in the two main suite
test files. With this include file these tests are skipped when run with
--lower_case_table_names=1 and --lower_case_table_names=2 mysqld
options. These two are case insensitive options.

Created an include file (not_lowercase1.inc) and added this to the two
rpl tests mentioned. This will skip the tests if the tests are run with
option --lower_case_table_names=1. These tests run when the value of
this option is anything other than 1.
