Rearrange struct members to remove padding bytes

[rootkea]

Hello!

On master, each struct has 8 padding bytes.

Found by: scan-build

Thanks!

There are 1028 lines removed and replaced, at 4 bytes per line thats 4k bytes of program memory which is not material.

The structures are only used for initialisation and configuration, so its not on any fast path, so cache effects are also not material.

It would also take a significant effort to check and verify every language type still works which is not available.

Sorry to sound harsh, but it seems like a lot of noise and effort for no significant gain.

4k bytes of memory saved without adding any additional code.

This PR could be reviewed over 2-3 days per 10-min a day as it involves only visual inspection.

Anyways, I leave it upto you maintainers wether to accept or reject the suggested change. :)
