mysql_stmt_affected_rows()
The problem was that affected_rows for prepared statement wasn't updated
in the client library on the error. The solution is to always update
affected_rows, which will be equal to -1 on the error.

there was two problems about charsets in embedded server
1. mysys/charset.c - defined there default_charset_info variable is
modified by both server and client code (particularly when
--default-charset option is handled)
In embedded server we get two codelines modifying one variable.
I created separate default_client_charset_info for client code
2. mysql->charset and mysql->options.charset initialization isn't
properly done for embedded server - necessary calls added
There actually was 3 different problems -
hash_user_connections wasn't cleaned
one strdupped database name wasn't freed
and stmt->mem_root wasn't cleaned as it was
replased with mysql->field_alloc for result
For the last one - i made the library using stmt's
fields to store result if it's the case.
--with-embedded-privilege-control options". One more (hopefully last) build
failure which was introduced during work on WL#2787 "Add view definer/owner
to the view definition..."
acl_init".
Updated calls to acl_init()/grant_init() in init_embedded_server() - their
signatures were changed recently, now they don't need argument for passing
pointer to THD object (this code was only compiled if one built embedded
server library with --with-embedded-privilege-control switch).
open cursor after mysql_stmt_execute" + post-review fixes.
The bug was caused by wrong flags in stmt->server_status on the client
side: if there was no cursor, the server didn't send server_status
flags to the client, and the old flags were used to set up the
fetch function of a statement. Consequently, stmt_read_row_from_cursor was
used when there was no cursor. The fix fixes the server to always
send server flags to the client.
