[Freeciv-Dev] [RFC] x & (1u << y)

[Raimar Falke <hawk@xxxxxxxxxxxxxxxxxxxxxxx>]

There are a lot of constructs like "x & (1u << y)" in the code:
 - city options, flags and roles
 - shared vision
 - embassy
 - claims
 - gotohand
 - known and sent in maphand

These all are used as a bool but aren't a bool. Should they be wrapped
with BOOL_VAL, a new test_bit or with functions specific to the
domains above?
