common: cmd_ide: use __weak and add prototypes 

clang chokes about the concept of having an alias to an
always_inlined function. gcc likely just ignores the always
inlined since binary sizes are equal before and after this
patch. Convert the aliases to weak functions and provide
missing prototypes.
