This reduces the amount of boilerplate code that is present in these
Makefiles by a lot.
It also makes it possible to update the Makefile rules in future without
having to re-generate all the Makefiles.

The up_xfer_cntrl and up_xfer_status modules have its own constraints files
in library/xilinx/common. Each IP which has an instance of these
modules, have to use these constraints files.
The following IPs were modified:
- axi_adc_decimate
- axi_adc_trigger
- axi_dac_interpolate
- axi_logic_analyzer
AND logic means that all enabled triggers need to evaluate to true, others
are don't care. Fix the logic to behave accordingly.

If the streaming bit is set, after the trigger condition is met
data will be continuosly captured by the DMA. The streaming bit
must be set to 0 to reset triggering.
In non-streaming mode we want direction changes to be applied immediately.
The current code has a typo and checks the wrong signal. overwrite_data
holds the configured output value of the pin, whereas overwrite_enable
configures whether the pin is in streaming or manual mode.
For correct operation the later signal should be used to decide whether a
direction change should be applied. Otherwise the direction change will
only be applied if the output value of the pin is set to logic high.

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:

The axi_logic_analyzer does not use the full width of the AXI interface
address. It only responds to register access in the first 32 registers.
Reduce the size of the AXI address to 7 bit accordingly. This allows the
scripts to correctly infer the internal register map size which will cause
the interconnect to filter out access to these unused register.
This slightly reduces utilization by getting rid of some pipeline
registers.

Xilinx recommends that all synchronizer flip-flops have
their ASYNC_REG property set to true in order to preserve the
synchronizer cells through any logic optimization during synthesis
and implementation.
