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. cc: Pavel Herrmann <morpheus.ibis@gmail.com> Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>
