Bug #13809 mysql-test: --replace_result option works on Windows incorrect

Description:
The option "--replace_result" works incorrect in a testcase on Windows/Cygwin if it called inside included file ("--source" option) and the files have DOS text format (each line ends by CRLF): 

This problem doesn't exist if testcases have UNIX format.

How to repeat:
1. Create 1.test file in main suite with following content (Note: make sure that the file has DOS format):

--replace_result $MYSQL_TEST_DIR MYSQL_TEST_DIR
eval SELECT 1,'$MYSQL_TEST_DIR'; 
--source include/1.inc

2. Create 1.inc file in main suite ("include" directory) with following content (Note: make sure that the file has DOS format):

--replace_result $MYSQL_TEST_DIR MYSQL_TEST_DIR
eval SELECT 2,'$MYSQL_TEST_DIR';

3. Run mysql-test-run.pl --record 1

4. Open 1.result file and look at line SELECT 2,'MYSQL_TEST_DIR'. Special character 0x0D was inserted after "R" character and before single quote.

place it into t/ directory

Attachment: 1.test (application/octet-stream, text), 108 bytes.

place it into include/ directory

Attachment: 1.inc (application/octet-stream, text), 83 bytes.

It is the result file

Attachment: 1.result (application/octet-stream, text), 125 bytes.

Pushed a fix to 5.0.19 and 5.1.8 that will make mysqltest convert all CR/LF to LF. Making it possible to read windows test files in a unix fashion.

Documented in 5.0.19 and 5.1.8 changelogs:

<listitem>
        <para>
          The <filename>mysqltest</filename> utility now converts all
          <literal>CR/LF</literal> combinations to <literal>LF</literal>
          to allow test cases intended for Windows to work properly on
          UNIX-like systems. (Bug #13809)
