All the hdl (verilog and vhdl) source files were updated. If a file did not
have any license, it was added into it. Files, which were generated by
a tool (like Matlab) or were took over from other source (like opencores.org),
were unchanged.
New license looks as follows:

Start the counter_to_interrupt_cnt counter when the counter_to_interrupt
value is written to the register map. This gives applications better
control over when the counter starts counting.
Also start the counter_from_interrupt on the rising edge of the interrupt
signal to avoid bogus values.

The IRQ signal goes to a asynchronous domain. In order to avoid glitches to
be observed in that domain make sure that the output signal is fully
registered.
This means that the IRQ signal is no longer mask when the control enable
bit is not set. Instead modify the code to clear the interrupt when the
control enable bit is not set. This turns it into a true reset for the
internal state.
