Bug #30271 NDB_LE_MemoryUsage.page_size_kb returns page size in bytes, not kilobytes

Description:
when catching the NDB_LE_MemoryUsage events created
as response to "ALL DUMP 1000" requests the page size
is reported in a field called page_size_kb. The field
name implies that the page size in kilobytes is returned
(32 for data and 8 for index memory), the actual result
is in bytes though (32768 for data, 8192 for index).

How to repeat:
see attached test program

- change the CONNECT_STRING within mgm_dump1000.cc (default: localhost)
- configure it with "configure --with-mysql=/mysql-prefix"
- build it with "make"
- run it
- issue an "ALL DUMP 1000"
- see the results

Suggested fix:
either rename the field to page_size_bytes instead of page_size_kb
or divide the result value by 1024 before storing it in page_size_kb

push into mysql-5.0-ndb-bj and mysql-5.1-new-ndb-bj

Documented in the 5.1.23-ndb-6.3.8 changelog as follows:

      
        Because NDB_LE_MemoryUsage.page_size_kb
        shows memory page sizes in bytes rather than kilobytes, it has
        been renamed to page_size_bytes.
        page_size_kb is now deprecated and thus
        subject to removal in a future release, although is currently
        remains supported for reasons of backwards compatibility. See
        -The Ndb_logevent_type Type-, for more information about
        NDB_LE_MemoryUsage.
