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:

Depending on the configuration of the clock source type of the input clock
the clocking wizard will instantiate all kinds of buffers on the input
clock signal.
For these particular projects there is no need to add any kind of buffer
since the source is already coming from a global clock buffer. So set the
configuration accordingly.
Avoids the following warning:
[Opt 31-32] Removing redundant IBUF since it is not being driven by a
top-level port. i_system_wrapper/system_i/sys_audio_clkgen/inst/clkin1_ibufg
Resolution: The tool has removed redundant IBUF. To resolve this
warning, check for redundant IBUF in the input design.

There is no need for the audio clock to be phase aligned to its source
clock. When phase alignment is disabled the MMCM uses an internal feedback
path without requiring external resources, so disable it.

Instead of manually specifying the input clock frequency let the core infer
it automatically. This makes it more straight forward to change the clock
frequency.

Neither the reset nor the locked signal is used in this design, so disable them. Avoids warnings about unconnected pins.

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.

Re-generate the Makefiles after a small update to the generation script:
- Entries are sorted alphabetically
- Empty dependency lines are skipped

The toplevel input/output signal names are lower case, but the signals
connected to the system_wrapper are upper case. Since verilog is case
sensitive this leaves the toplevel input/output signals unconnected. Fix
this by using lower case names everywhere.

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
