Submission save and draft save will be broken if field keys is too long

Its me again. :)

If you choose too long fieldkeys, the generated post ids will be too long, and suhosin will be drop it. This isn't too big problem, fix it if you rename your components. But somebody can't read syslog can't find this error.

In syslog:

Oct 26 15:35:10 alma suhosin[19678]: ALERT - configured request variable name length limit exceeded - dropped variable 'row__tantargyfelels_tabla__30__tantargyfelels_tabla_oktato_eha_kod' (attacker '1.2.3.4', file '/mnt/datalv/www/drupal6/index.php')

PostID generated: row__*table_field_key*__*row_id*__*table_element_field_key*
Suggest for fix it: don't use field keys, cid is unique and correct for this object. If you want i will create a patch, but now only rename fields.
