It never really worked anyway.

The "fullscreen" variable is set by the UI. That triggers a vout
control request. Then the vout thread actually switches to/from
full screen mode. Setting the "fullscreen" variable again then would
trigger a live loop in some circumstances, and should be useless.

This will skip auto-select of libraries under the GPL

Still documents old behaviour.

(In practice, all of these were only used in little endian anyway.)

There is still a random offset between A/V which stays
constant until there's a flush but hopefully testing should
give a clue how to fix it.

Note: the symbols required are present only since 2.2

Close #7786

That causes some duplication, but that is required for clobber lists.

If foo[i] or bar[i_index] are used in TAB_REMOVE / TAB_FIND, they will
use another variable with local scope declared inside the macro.

for (int i = 0; i < 1; i++) {
    TAB_REMOVE( count, array, foo[i] );
}

will expand to:

for (int i = 0; i < 1; i++) {
    int i_index;
    .....
    for (int i = 0; i < count; i++)
        if (array[i] == foo[i])
        {
            index = i;
            break;
        }
    .....
}

And inner scope i is used to index foo, instead of the outer scope i
which we would expect without knowing the content of the macro.
