Normalize directory names before adding them to default_directories.

A user could not override system-wide settings in their ~/.my.cnf,
because the DEFAULT_SYSCONFDIR was being searched last.  Also, in
some configurations (especially when the --sysconfdir compile-time
option is set to /etc or /etc/mysql), the system-wide my.cnf file
was read multiple times, causing confusion and potential problems.

Rearrange default directories to conform to the manual and logic.
Move --sysconfdir=<path> (DEFAULT_SYSCONFDIR) from the last default
directory to the middle of the list.  $HOME/.my.cnf should be last,
so the user is able to override the system-wide settings.

Change init_default_directories() to remove duplicates from the
list.

Recognize the --no-defaults, --defaults-file and --defaults-extra-file
options.  Treat old --config-file argument as if --defaults-extra-file
had been specified instead.

Plus a few other defaults-related cleanups.

Move get_thread_lib to mysys/my_pthread.c
Set 'thr_client_alarm' to signal number used by thr_alarm to give alarms

Move get_thread_lib to mysys/my_pthread.c
Set 'thr_client_alarm' to signal number used by thr_alarm to give alarms

  Changed header to GPL version 2 only

bug #25104

bug #25104

- Removed not used variables and functions
- Added #ifdef around code that is not used
- Renamed variables and functions to avoid conflicts
- Removed some not used arguments

Fixed some class/struct warnings in ndb
Added define IS_LONGDATA() to simplify code in libmysql.c

I did run gcov on the changes and added 'purecov' comments on almost all lines that was not just variable name changes

(Mostly in DBUG_PRINT() and unused arguments)
Fixed bug in query cache when used with traceing (--with-debug)
Fixed memory leak in mysqldump
Removed warnings from mysqltest scripts (replaced -- with #)

 - Check that length of value is longer than 1 before decrementing length by 2.
 - Backport from 5.0, make it possible to use my_print_defaults in tests

 - Grab the path from "configure --sysconfdir=<path>" and set it as
   the first place to look for my.cnf files
   Do this both in Makefiles for libmysql and mysys
 - Patch provided by Francesco Riosa. Thank you!

 analog with defaults_extra_file and defaults_grouop_suffix

Before the fix in ~Prepared_statments we got a memory leak when executing mysql_client_test.test
Note that test 'variables.test' fails.
This will be fixed when Jimw pushes the fix for Bug 10351

Ensure mysql_close() is called if mysql_set_character_set() fails

Changed defaults option --instance to --defaults-group-suffix
Changed option handling to allow --defaults-file, --defaults-extra-file and --defaults-group-suffix to be given in any order
Changed MYSQL_INSTANCE to MYSQL_GROUP_SUFFIX
mysql_print_defaults now understands --defaults-group-suffix
Remove usage of my_tempnam() (not safe function)
if( -> if ( and while( to while (

the new installer and GUI tools expect. (Bug #10419) Also, dynamically bind to
GetSystemWindowsDirectory() so that it works on all platforms. (Bug #5354)

       which enables having multiple mysqld in same my.cnf 
       without mysql_multi or IM

Changed name of function my_correct_default_file to
modify_defaults_file. Improved function and fixed some
bugs in it.

  Disabled use of GetSystemWindowsDirectory() when compiled with VC6
mysql.cc:
  Removed unused variable 'field' from print_warnings()
libmysql.dsp:
  Added "my_chsize.c" and "my_seek.c"
mysqlclient.dsp:
  Added "my_chsize.c"

Produce warnings of wrong cast of strings to signed/unsigned.
Don't block not resolved IP's if DNS server is down (Bug #8467)
Fix compiler problems with MinGW (Bug #8872)

add handling of configuration file in the Windows shared system
directory. (Bug #5354)
