The code that set up data to be passed to user-defined functions was very
old and analyzed the "Type" of the data that was passed into the UDF, when
it really should analyze the "return_type", which is hard-coded for simple
Items and works correctly for complex ones like functions.

It's not possible to flush the global status variables in 5.0

 - Improve icheck rules in Makefile.am


include/Makefile.am:
  Remove m_ctype from BUILT_SOURCES, it has been in bk for a looong time.
  Improve the icheck rules
   - Abort make if icheck fails to compare, very important.
   - Don't include include files from /usr into the icheck file. Avoids problem when running
     icheck on different machines.
   - If no icheck is availabel, touch the mysql_h.ic file so it exists for "make dist"
include/mysql_h_abi.ic:
  Remove all include files from /usr, no need to check that!

 - Add two null bytes in  "buff" variable allowing us to call
   get_arg two times also for strings longer than sizeof(buff) 


client/mysql.cc:
  Make sure there are _two_ zero bytes at the end of buff, to allow 'get_arg' to be
  called twice on long strings. The first time it will mark end of string with a
  zero and the second time it will "skip ahead" to the first zero, and the find the
  second one indicating end of buff.
mysql-test/r/mysql.result:
  Update test results
mysql-test/t/mysql.test:
  Add tests for "com_connect" function in mysql
  Add test reported in bug

When executing the init_connect statement, thd->net.vio is set to 0, to         
forbid sending any results to the client. As a side effect we don't log         
possible errors, either.                                                        
                                                                                
Now we write warnings to the error log if an init_connect query                
fails.                                                                          


sql/sql_parse.cc:
  Fix for bug #22158: Errors in init_connect terminate connections silently
  - raise warnings if the init_connect execution fails.
