The relay log may not be open for some reason (e.g. disk error) after rotation,
and using it causes the slave crash.

Fix: check we have it open before access, return error otherwise.


sql/slave.cc:
  Fix for bug #10798: If relay log fails to rotate, slave will crash after
    - check if the relay log is open before any access.

bug #25104


mysys/default.c:
  Added support for /etc/mysql after /etc in the search path for my.cnf

- When this bug was corrected it changed the behavior 
  for data/index directory in the myisam test case.
- This patch moves the OS depending tests to a non-windows
  test file.


mysql-test/r/myisam.result:
  moved test from myisam to symlink; new result file
mysql-test/r/symlink.result:
  moved test from myisam to symlink; new result file
mysql-test/t/myisam.test:
  moved test from myisam to symlink

mysql-test/mysql-test-run.pl:
  Pass "--no-defaults" to embedded server as "--server-arg=--no-defaults"

    - test* targets are identical (as much as possible) to 5.0 & 5.1 versions
    - use @PERL@ ./mysql-test-run.pl, instead of depending on /usr/bin/perl location
    - PHONY: target includes all test targets


Makefile.am:
  - test* targets are identical (as much as possible) to 5.0 & 5.1 versions
  - use @PERL@ ./mysql-test-run.pl, instead of depending on /usr/bin/perl location
  - PHONY: target includes all test targets

mysql-test/t/kill.test:
  Move the connect of second connection to just before the query to be killed are sent.
  This introduces less variance since the connect time is not included in the delay
  we want between send of query and kill.

 - Use "mysql_field_count" to determine if there is a need to
   call "mysql_store_result"


client/mysqltest.c:
  Only call 'mysql_store_result' if 'mysql_field_count' is greater than 0
  indicating that this query has a result set.  This change is mainly since
  if mysql_store_result fails the value returned by mysql_field_count will be reset.

 - Thanks to Vasil Dimov for the patch!


client/mysqltest.c:
  Use my_snprintf to protect against exceeding size of buff
  Since variable name and valu might not be null terminated it's necessary to
  provide the length of the format specifiers.

- Using DATA/INDEX DIRECTORY option on Windows put data/index file into
  default directory because the OS doesn't support readlink().
- The procedure for changing data/index file directory is 
  different under Windows.
- With this fix we report a warning if DATA/INDEX option is used,
  but OS doesn't support readlink().


mysql-test/r/windows.result:
  - updated result file.
mysql-test/t/windows.test:
  - Added test case to verify we get warnings if we specify DATA/INDEX
    DIRECTORY on a platform which doesn't support readlink().
sql/sql_parse.cc:
  - Added warnings if DATA/INDEX DIRECTORY option is used but not supported
    by the target platform.
