fixed Clang warnings about one-bit-wide boolean integers (-Wsingle-bit-bitfield-constant-conversion)

* gboolean is defined as gint which is a signed type.
  A gboolean 1-bit-wide bitfield cannot have the values 0 and 1 but only 0 and -1.
* This wasn't practically a bug unless you would try to compare one of those bitfields
  with TRUE.
* All of those bitfields are now guint, even though this is less self-documenting.
