"Table is already up to date" vs. "OK"

On MacOSX 10.5 when you cast something to "bool"
(the built in C type) it takes values 0 or 1 
instead of 0-255 as it seems to be on older compilers.
Fixed by removing the typecast (not needed).
No test case needed : there are tests that test it.

The problem: ha_partition::read_range_first() could return a record that is 
outside of the scanned range. If that record happened to be in the next 
subsequent range, it would satisfy the WHERE and appear in the output twice.
(we would get it the second time when scanning the next subsequent range)

Fix: 
Made ha_partition::read_range_first() check if the returned recod is within
the scanned range, like other read_range_first() implementations do.

Changed the option location in code so that --help will show it in
lexical option order.

This is for bug #26215: mysql command line client should not strip
comments from SQL statements

added check for the result of mysql_unpack_partition()

failing 'INSTALL PLUGIN' statement doesn't work in embedded server
as we disable library loading there.
Fixed by enabling loading libraries (#define HAVE_DLOPEN), what also
makes UDF working in the embedded server.

Comparison of a BIGINT NOT NULL column with a constant arithmetic
expression that evaluates to NULL caused error 1048: "Column '...'
cannot be null".

Made convert_constant_item() check if the constant expression is NULL
before attempting to store it in a field. Attempts to store NULL in a
NOT NULL field caused query errors.

The problem was in incorrectly calculated length of the buffer used to
store a hexadecimal representation of an index map in
select_describe(). This could result in buffer overrun and stack
corruption under some circumstances.

Fixed by correcting the calculation.
