The new module contains another wb crossbar. Therefore the memory
mapping has changed.
This has been done for the future svec design with two fmc slots.

This solves the problem of trigger firing even when the data was below the threshold.

Now the figures dir is common to all doc.

In multi-shot mode, this was causing the end_acq not to be generated
for single sample acquisitions.

Also fix the number of samples taken in multi-shot mode.
total = 1 (trigger) + pre_trig + post trig.

- Reports after synthesis and place+route.
- sdb meta-info update in (sdb_meta_pkg.vhd).

Add file header to sdb_meta_pkg.vhd

Was setting the interrupt source bits regardless of the interrupt mask.
Now a source bit is set only if the corresponding mask bit is set.

This information is now in sdb header (meta info).
