Libs : dashed splitterbar (PB4.20b1)

[eddy]

I fixed #pb_any and i made a crash test.
12* 8 = 96 dashbars
with 2*96 = 192 buttons

I found an critical example. (cascading dashbar)
[[[1]2]3]4]..............60]

In this case, the gadget have some problems to resize its content.
One of Callback procedures crashes because of nulled customdata pointer.

Did you upload a new version, I'll see if your new version still crashes here.
