Bug#11896296 REMOVE LGPL LICENSED FILES IN MYSQL 5.0

The LGPL license is used in some legacy code, and to
adhere to current licensing polity, we remove those
files that are no longer used, and reorganize the
remaining LGPL code so it will be GPL licensed from
now on.

Note:  This patch only removed LGPL licensed files
       in MySQL 5.0, and is the first of a set of
       patches to remove LGPL from all trees.
       (See Bug# 11840513 for details)



include/my_compare.h:
  Mostly code moved in from my_handler
include/my_global.h:
  AIX-only code.   Function used to be in my_port.c
  Inlining instead.
libmysql/Makefile.shared:
  my_gethostbyname and my_port is removed
myisam/mi_check.c:
  ha_find_null is moved from my_handler and made static.
