When the TTL selection switch is set for TTL-BAR signals, the pulse counters
were starting from the value 1. This was because the input channel is
first sent through a synchronizer FF chain, which was reset by the
same reset signal as the rest of the logic.

Due to the reset pulse inside the logic and the fact that when the TTL switch
is set to TTL-BAR, a non-existing signal represents a high level, this
high level was detected (due to the sync FF chain) only after the reset pulse.
This resulted in a rising edge on the trigger signal, which resulted in the
pulse counters incrementing to '1' on every reset.

This problem has been solved by not resetting the sync FF chain.

This was done by reading the whole value of the 8-bit MPT field
after the magic sequence is input. Before, only the number of bits
corresponding to the number of channels at the input was read, which
could result in a pulse being generated when a wrong channel value with
a "correct" mask is input to the field, as for example:

- on the six-channel CONV-TTL-BLO, 0x9 in MPT gets masked on three bits to 0x1,
thus a pulse is generated on CH1

Prior to this commit, manual pulse triggering did not work when the glitch
filter was enabled. Now, this was fixed by extending the trigger pulse the
conv_man_trig module generates. This accounts for the situation where the
pulse generator has the glitch filter enabled.

I also fixed a bug in conv_pulse_gen; this fix was commited two commits ago.
The bug consisted of the gf_off part of the pulse generator triggering even
when the glitch filter was enabled. This resulted in a continuous high pulse
generated on the output when the glitch filter was switched from on to off.
Granted, such a situation should not occur in operation, since a board needs
to be removed from the crate in order to flip a switch. Nonetheless, it was a
but, so I've fixed it by making sure the gf_off part of the design only triggers
when the glitch filter is disabled:

if (en_i = '1') and (gf_en_n_i = '1') then
  pulse_gf_off <= '1';
end if;

A warning will be placed in the docs for release versions 1.0 and 0.0 (golden).
