SYNOPSIS
sp_use_new_db()
thd thread handle
new_db new database name (a string and its length)
old_db [IN] str points to a buffer where to store the old
database, length contains the size of the buffer
[OUT] if old db was not NULL, its name is copied
to the buffer pointed at by str and length is updated
accordingly. Otherwise str[0] is set to '\0' and length
is set to 0. The out parameter should be used only if
the database name has been changed (see dbchangedp).
dbchangedp [OUT] is set to TRUE if the current database is changed,
FALSE otherwise. A database is not changed if the old
name is the same as the new one, both names are empty,
or an error has occurred.
RETURN VALUE
0 success
1 access denied or out of memory (the error message is
set in THD)
