It does look like the value you pass to
proto_tree_add_boolean(tree, id, tvb, start, length, value);
is not a 1 or a 0 it is the raw data byte containing the boolean at the
position defined by the mask.
If I am correct this makes the documentation a bit missleading.
Anybody know if there is a function that returns the boolean (1 or 0) value
of the flag or do I have to do the masking myself to get it?

I have not got as far as getting the value of the boolean, I was was
looking for a function to extract it.
I am also not sure if 'value' really is the value of the boolean or the
value of the byte containing the boolean (along with other data)?

Actually the last 'value' is, well, the value of the boolean (on the
system running Wireshark). You must have already pulled out 'value'
using one of the tvb functions (and bit shifted it, if necessary).
