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.

link with libm, and also with libdl which is needed

This makes use of a 3rd party circular buffer licensed under MIT.

TODO: Pause, TimeGet, Flush

Take in account the time elapsed since the last callback

Needs testing on device

TimeGet is left as an exercise for tomorrow

this can happen when moving buffers between our 2 linked lists

They stopped working in version 2.0 and never made much sense.
