for bug #15936.

On some platforms fenv.h may #undef the min/max macros
defined in my_global.h.

Fixed by moving the #include directive for fenv.h from
mysqld.cc to my_global.h before definitions for min/max.

include/my_global.h:
  Moved #include <fenv.h> from mysqld.cc.
sql/mysqld.cc:
  Moved #include <fenv.h> to my_global.h.

In the output message for --help entry for -H --HELP was missing.
Added this entry while printing the help text.

storage/myisam/myisamchk.c:
  Added entry for -H --HELP while printing message for -? --help

Revised the test to include a test of completion_type = 1 as well as making the test more readable / worthwhile
Removed the master.opt file as it was redundant / unnecessary.

mysql-test/suite/sys_vars/t/completion_type_func-master.opt:
  Removed as redundant.  Test uses include/have_innodb.inc.

      
There was a problem when a DELIMITER COMMAND is not the first 
command on the line. I this case an extra line feed was added
to the glob buffer and this was causing subsequent attempts 
to enter this delimiter to fail.
Fixed by not adding a new line to the glob buffer if the 
command being added is a DELIMITER

  the glob buffer

Add all HA error numbers and descriptions to perror.

Add reminder to header.

This is already fixed in smarter ways in future codebases, and this 
codebase is unlikely to change, since new development is forbidden
here.

Bug#41112: crash in mysql_ha_close_table/get_lock_data with alter table

The problem is that the server wasn't handling robustly failures
to re-open a table during a HANDLER .. READ statement. If the
table needed to be re-opened due to it's storage engine being
altered to one that doesn't support HANDLER, a reference (dangling
pointer) to a closed table could be left in place and accessed in
later attempts to fetch from the table using the handler. Also,
if the server failed to set a error message if the re-open
failed. These problems could lead to server crashes or hangs.

The solution is to remove any references to a closed table and
to set a error if reopening a table during a HANDLER .. READ
statement fails.

mysql-test/include/handler.inc:
  Add test case for Bug#41110 and Bug#41112
mysql-test/r/handler_innodb.result:
  Add test case result for Bug#41110 and Bug#41112
mysql-test/r/handler_myisam.result:
  Add test case result for Bug#41110 and Bug#41112
sql/sql_handler.cc:
  Remove redundant reopen check.
  Set errors even if reopening table.
  Reset TABLE_LIST::table reference when the table is closed.

There is no test case in this change set as the test depends on
a testing feature only available on 5.1 and later.

  Remove redundant reopen check.
  Set errors even if reopening table.
  Reset TABLE_LIST::table reference when the table is closed.
