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:

Calculate the output clock frequencies based on the input clock frequencies
and the default divider settings and configure the output clock pins
accordingly. This allows connected peripherals to infer the frequency of
the clock.

Instead of having to manually specify the input clock period infer the
values from the block design. This means that less configuration parameters
need to be changed if the clock input frequency changes.

Add interface definition for the input and output clocks. This will allow
the tools to recognize them as clocks and enable things like clock
frequency propagation.

The secondary clock inputs and outputs of the axi_clkgen are rarely used.
Add enable parameters that need to be explicitly set before they are
available. This allows to hide the secondary clock pins when they are not
used in the block design.
There are currently no projects which use the secondary clock inputs or
outputs so there is no need to set these new parameters anywhere.

Vivado infers the type of floating point type parameters as integer if the
value can be expressed as an integer (i.e. decimal places are 0). To
correctly infer them as floating point parameters add types to the
parameter declaration.

Add .gitattributes file which sets up the eol encoding handling. This will
make sure that we get a uniform eol encoding across different operating
systems.

Clean ran for a project will clean only the project files.
Clean-all ran for a project will clean also the library files on which the project depends.
The clean commands will only remove specific files and directories.
The top Makefile allows several options(per suggestion from jameyhicks):
make fmcomms1.zed will run "make all" in projects/fmcomms1/zed/
make clean will run "make clean" for all the projects
make clean-all will run "make clean" for all the projects and libraries
make lib will run "make all" for the library files
This is unused and unneeded. The AXI interconnect will make sure that a
peripheral only gets requests that are meant for it, there is no need to
check the address in the peripheral itself.
