Change OS_THREAD_LIBSPACE_NUM to be defined as a (compiler) macro

[AriParkkila]

OS_THREAD_LIBSPACE_NUM is defined to 4, which is not a good default in all cases. This change makes it possible to give OS_THREAD_LIBSPACE_NUM also as a (compiler) macro.

Looks reasonable to me as we have those pre-processor guards in all other places as well.
I'd like to question if this guard should only be used in case no object specific memory pools are used. Why not surround the whole block with that guard?

[RobertRostohar]

The guard as initially proposed is fine.
However this is a configuration file and therefore versioning needs to be taken into account. Version of the file needs to be changed to 5.5.1 at the top of the file and also in the pack description file (pdsc).

@RobertRostohar Just updated revisions, please re-review.

@JonatanAntoni @RobertRostohar Is there something more you need or is this ready to go in?

[JonatanAntoni]

Hi @AnttiKauppila,
sorry for leaving this for couple of weeks. As I stated during review "someone" needs to update all the references to RTX_Config.h (not only the first occurance) in the PDSC file, properly. May I ask you to update your PR accordingly, please?
Thank you again for your contribution,
Jonatan

@JonatanAntoni I just updated the PDSC file, ready for merge?

[JonatanAntoni]

Hi @AriParkkila,

looks good. Thank you very much.
May I ask you to rebase your changes to develop, please?

Thanks again,
Jonatan
