flaws list)
TODO: 
 * verify that no sequence of API calls produces SIGSEGV.
 That is, verify that mysql_stmt_init  -> mysql_stmt_fetch is OK,
 or mysql_stmt_prepare -> mysql_stmt_fetch_column is OK and sets
 meaningful error.
 * remove alloc_stmt_fields call
 * revise stmt->state codes and statement states.
 * there are other items in prepared statements 'to fix' document.

Done:
 - cleanups and comments
 - revision of prepared statement error codes.
 - mysql_stmt_prepare is now can always be called (that is, you can reprepare
   a statement)
 - new implementation of mysql_stmt_close and fetch cancellation


include/errmsg.h:
  - CR_NOT_ALL_PARAMS_BOUND - this error code wasn't used until now. 
    Apparently it was added in advance, but then interface of
    mysql_stmt_bind_param changed. Now it's not possible to bind only some
    parameters - either all or none of parameters are bound.
    This error code  is renamed to CR_PARAMS_NOT_BOUND
  - CR_FETCH_CANCELLED - error code set on server side when fetch from 
    MYSQL_RES or MYSQL_STMT (in blocking mode) was cancelled because of
    intercepting call to mysql_stmt_close
  - CR_NO_DATA - this is proposed error code to return from 
    mysql_stmt_fetch_column if no row was fetched (by any type of fetch).
    We always can fall back to CR_COMMANDS_OUT_OF_SYNC though.
    Need reviewer's opinion on this one.
include/mysql.h:
  - added unbuffered_fetch_owner member to MYSQL to point to MYSQL_RES 
    or MYSQL_STMT which is used to fetch result at the moment.
    This is to be able to set CR_FETCH_CANCELLED error without fantoms.
  - added unbuffered_fetch_cancelled boolean variable to MYSQL_STMT and 
    MYSQL_RES structures
  - rename PREP_STMT_STATE -> enum enum_mysql_stmt_state
  - members of MYSQL_STMT ordered by size.
  - removed members of MYSQL_STMT: current_row, result_buffered,
    last_fetched_column, last_fetched_buffer, query
  - renamed members of MYSQL_STMT: param_buffers -> bind_param_done, 
    res_buffers -> bind_result_done
  - now mysql_stmt_fetch calls stmt->read_row_func to read row either from 
    buffer or from network.
include/sql_common.h:
  declaration for flush_use_result
libmysql/client_settings.h:
  stmt_close declaration removed
libmysql/errmsg.c:
  Error messages for changed and added error codes.
libmysql/libmysql.c:
  Many changes:
  - some unused variables removed
  - cleanups
  - better error reporting
  - some function calls commented
  - alloc_stmt_fields is now called right after execute, to not read
    mysql->fields of some other statement
  - new implementation of mysql_stmt_fetch - this is also with cursor
    fetch in mind (to implement cursor fetch I'll just need to write
    special read_row function for it, so this change will be local)
  - implementation of fetch cancellation, including complete rewrite of
    mysql_stmt_close
  - now mysql_stmt_free_result doesn't free results of other statements.
sql-common/client.c:
  - implementation of flush_use_result
  - implementation of fetch cancellation
  - changed behaviour of mysql_close in regard to mysql_stmt_close - now 
    mysql_close just set stmt->mysql to 0

sql/item_strfunc.cc:
  that's the right fix

include/config-win.h:
  implementation of ULL macro for Windows
include/my_global.h:
  ULL macro defined: we need this macro because ULL qualifier is not defined 
  on systems withoug unsigned long long
sql/item_func.cc:
  new ULL macro caused conflict with class for user level lock ULL.
  ULL renamed to User_level_lock
sql/item_func.h:
  ULL -> User_level_lock
sql/mysql_priv.h:
  merge error fixed: LL defined in my_global.h
sql/mysqld.cc:
  ULL macro used for long long constants to fix compilation failure on gcc 3.*
sql/sql_class.h:

#2709 Affected Rows for ON DUPL. KEY undocumented, perheps illogical 
1. added COPY_INFO::updated to work with it in
   'insert .. on duplicate' instead of COPY_INFO::deleted
2. added affected rows to output of "info:" in mysqltest.c


client/mysqltest.c:
  added "affected rows" to output of "info : "..
mysql-test/r/insert_update.result:
  added tests for affected rows with insert .. duplicate (bug #2709)
mysql-test/t/insert_update.test:
  added tests for affected rows with insert .. duplicate (bug #2709)
sql/sql_class.h:
  added COPY_INFO::updated
sql/sql_insert.cc:
  get write_record to work with COPY_INFO::updated instead of 
  COPY_INFO::deleted for 'insert ... duplicate' statement

COM_EXECUTE packet" and #2795 "prepare + execute without bind_param crashes
 server" and #2473 "seg fault running tests/client_test.c": 
- length checking added to packet parser 
- default impelemntation of Item_param::set_param_func will work in
case of malformed packet.
No test cases are possible in our test suite, as there are no tests 
operating on protocol layer.


sql/item.cc:
  Default set_param function implemented: this is to not sigsegv in case
  of malformed packet with no parameters data.
sql/item.h:
  - Item_param constructor moved to .cc to be able to assign set_param_func.
  - now embedded and ordinary versions of set_param have the same signature.
sql/mysql_priv.h:
  mysql_stmt_execute now requires packet_length
sql/sql_parse.cc:
  mysql_stmt_execute now requires packet length.
sql/sql_prepare.cc:
  - length checking added to all functions working with network packet.
  - set_param_func's in embedded and ordinary version now have the same 
  signature
