Bug #55854 MySQL AB should not be AUTHOR, copyright incorrect

Description:
In Server 5.5 and later, we use "MySQL AB" as the author 
in the audit_null file. This should be changed to "Oracle 
Corp" since "MySQL AB" doesn't exist anymore.

In addition, the copyright/license notice is incorrect; Oracle 
is not mentioned. Since the 5.5GA release will be in 2010,
all copyright notices must be changed to show Oracle as the 
owner.

How to repeat:
The following is found in /plugin/audit_null/audit_null.c:

mysql_declare_plugin(audit_null)
{
  MYSQL_AUDIT_PLUGIN,         /* type                            */
  &audit_null_descriptor,     /* descriptor                      */
  "NULL_AUDIT",               /* name                            */
  "MySQL AB",                 /* author                          */
  "Simple NULL Audit",        /* description                     */
  PLUGIN_LICENSE_GPL,
  audit_null_plugin_init,     /* init function (when loaded)     */
  audit_null_plugin_deinit,   /* deinit function (when unloaded) */
  0x0002,                     /* version                         */
  simple_status,              /* status variables                */
  NULL,                       /* system variables                */
  NULL
}

Please change author to "Oracle Corp".

In addition, the copyright notice of the audit_null.c and the 
CMakeLists.txt files must be changed to the following:
