Missing Val_string and String_val macros

[jserot]

These macros are not listed in src/bytecode/vm/values-xxx.h.
Is this deliberate ?

I think that's because in OMicroB, static strings are stored in the flash memory (as much as possible in any case) in order to save RAM.
If I understand correctly, that means access to the string must be done on a character basis (otherwise you would have to basically copy the string in the RAM, which a simple macro like String_val probably shouldn't do).
I hope that's helpful. Maybe @bvaugon can explain better ?
