WL#604 Privileges in embedded library
code added to check privileges in embedded library
NO_EMBEDDED_ACCESS_CHECKS macros inserted in code so we can exclude
access-checking parts. Actually we now can exclude these parts from
standalone server as well. Do we need it?
Access checks are disabled in embedded server by default. One should
edit libmysqld/Makefile manually to get this working.
We definitely need the separate configure for embedded server

  SET character_set_connection=newcharset;
  SELECT hex('text');

The above sequence failed in some cases.

Prepared statements in embedded server
Several changes in library code with two goals:
to make mysql_prepare_stmt working in embedded server
to get rid of #define mysql_interface_func mysql->methods->interface_func
in user's interface

10 now means "number of characters", not number of bytes.

CREATE TABLE t1(a NVARCHAR(10))
This is for compatibility with MSSQL, DB2, Informix and some other DBMSs.

Note, standard SQL doesn't have "NVARCHAR" syntax.
There are only these syntaxes in SQL2003:
 NATIONAL VARCHAR
 NCHAR VARCHAR
 NATIONAL CHARACTER VARYING 
 NCHAR VARYING

- Tests were added for all the above syntaxes.

to SHOW SLAVE STATUS.
