*with --with-charset=utf8*

Problem: wrong LONG TEXT field length is sent to a client 
when multibyte server character set used.

Fix: always limit field length sent to a client to 2^32,
as we store it in 4 byte slot.

Note: mysql_client_test changed accordingly.


sql/protocol.cc:
  Fix for bug#19829:make test Failed in mysql_client_test 
  *with --with-charset=utf8*
    - limit field length sent to client to UINT_MAX32 as 
      it may exceeds 32 bit slot for LONG TEXT fields if
      thd_charset->mbmaxlen > 1.
tests/mysql_client_test.c:
  Fix for bug#19829:make test Failed in mysql_client_test

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.
