add osmo_str_startswith()
Move from a static implementation in tdef_vty.c to utils.c, I also want to use this in osmo-msc. The point is that the telnet VTY allows unambiguous partly matches of keyword args. For example, if I have a command definition of: compare (apples|oranges) then it is perfectly legal as for the vty parser to write only compare app One could expect the VTY to then pass the unambiguous match of "apples" to the parsing function, but that is not the case. Hence a VTY function implementation is faced with parsing a keyword of "app" instead of the expected "apples". This is actually a very widespread bug in our VTY implementations, which assume that exactly one full keyword will always be found. I am now writing new commands in a way that are able to manage only the starts of keywords. Arguably, strstr(a, b) == a does the same thing, but it searches the entire string unnecessarily.
