Description

There are a lot of

 static pn_class_t 

structs that could be

 static const pn_class_t 

and this would move them into the read only part of the program and hence save RAM in an embedded system.

There is also a table in the ssl implementation

 dh2048_p 

which can be const.

After adding these consts my build has nothing left in the .data section due to the proton library.
