flag is sent to server with placeholder types.
There were no need to extend the protocol as one additional byte
was reserved for placeholder code, when placeholder code is in range 0-255.
So this byte is now used for flags. Post-review fixes added.

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
Done clean-up in prep stmt API functions:
1) Removed some checks that were performed only in debug version
were making debug version more tolerable to user errors than
production (and thus caused problems for example masking some
bugs).
2) Also removed some other checks to make prep stmt API
consistent with the rest of C API (this also in line with
general politics - make checks in only those places where
errors are very common and hard to spot).
now mysql_server_init is called from mysql_init with fake parameters
mysql_once_init code included to mysql_server_init.
embedded-specific initialization is in init_embedded_server function
Client option secure-auth deployed on all possible layers:
- mysql client command-line and config file option
- mysql_options option MYSQL_SECURE_AUTH
- mysql_real_connect will automatically take into account that option if
mysql->options.my_cnf_file/my_cnf_group is set
New multi-key-cache handling. This was needed becasue the old one didn't work reliable with MERGE tables.
ALTER TABLE table_name ... CHARACTER SET ... now changes all char/varchar/text columns to the given character set
(One must use ALTER TABLE ... DEFAULT CHARACTER SET ... to change the default character set)
Fixed that have_compress is detected properly (fixes problems with func_compress.test on platforms without zlib)
New syntax for CACHE INDEX ('keys' is optional if no index name is given and one mentions the key cache name only ones)
Removed compiler warnings
Added mysql_set_server_option() to allow clients like PHP to easaily set/reset the multi-statement flag.
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
embedded library
some dirty places cleaned:
uint removed from mysql.h as Miguel suggested
empty_string renamed as my_empty_string to get rid of name's intersections
using embedded library
embedded library
I decided to get rid of #define mysql_some_function in mysql.h
It puzzles users and makes problems with dynamic libraries
Finally, there are only two functions left, that are covered with
the #define-s and it won't hurt performance at all
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
