When everthing else is given absolute, using a width relative to
\textwidth easily produces problems...

Added functionality to automatically spawn PTY pair.
Can now replace a CONF_DONE message by an UNDERRUN.

The target to produce an intermediate .aux file for latex documents
was removed in 071d7b5c to simplify the build without taking the overall
docs/ makefile into account. The latter relies on a destinct target for
.aux files.
This commit adds it back but makes sure that failed attempts to build it
still get retried by using pdflatex' drafmode (which does not write the
PDF file itself).

Also, fix some other minor issues in the makefile and the generation of
the directory of acronyms.

 - fix bottom right copy&paste error
 - make sure all text is FreeSans (not Nasa)
 - make fonts a bit smaller to fit better between pins

The previous version sometimes failed to rebuild a document after a
failed build attempt followed by a correct fix.

Added trigger to UM.

Added constraint files for Vivado.

Added FIU names to cfg

Makes Synplify for iCE40 want to implement buffer in RAM but then fail
due to reset.

Added template qsf for FIJI pin constraints
Added FIU names
Added connection figure to user manual section

For future latency estimation

This includes generated files apart from the instrumented netlist.
The latter just gets a header stating which version of FIJI generated it etc.

Also rename existing licenses to include a .txt suffix and
the license's version.
