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).

SPEC front panel leds reserved for WR.
SPEC aux leds used as follow:
0 = fpga programmed (heartbeat)
1 = trigger
2 = acquisition done
3 = dma done

Was using the wrong fifo empty signal to generate the valid signal.

Is not recording the rigth amount of samples in the ddr.

Was using custom coregen fifo and dpram.

Calibration data storage in eeprom with sdbfs (was ipmi only).

no_coregen branch generic_fifo is buggy, not outputing the last written data
from time to time.
Was causing the gennum core to hang (waiting forever on the last data).
