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:

Currently the BRAM and data registers in the util_axis_data are ungated
when the FIFO is ready to receive data. This good for high-performance
since it reduces the number of control signals. But it is bad from a power
point of view since it causes additional reads and writes.
Change the core gate the BRAM and data register if either the consumer is
not ready to accept data or the producer has no data to offer.

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

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
Add a room output on the input side that reports how many free entries the
FIFO has and a level output on the output side that reports how many valid
entries are in the FIFO.
Note that the level output is only accurate if the output of the FIFO is not
registered, otherwise it might be off by one.

Add a option to specify whether the FIFO should have a registered output
stage or not. This is useful if the user wants to implement that stage
itself.

Bring back the AXIS FIFO as a separate module instead of embedding it into
the DMAC module. This makes it possible to use it in other modules outside
of the DMAC.
