output/srzip: accept arbitrary input and output unit sizes

Commit c03aaf342c3f introduced a check and refused to store sample data
when the feed would not exactly match an expected width that was derived
from the device's or input's total count of logic channels. Earlier
versions assumed the match but never checked (immediately forwarded
session feed content to the ZIP archive). Existing applications may not
be prepared to process the resulting archive where meta data and samples
disagree on essential properties. The fatal condition aborted execution,
which was perceived as a regression. A message was added later to
communicate that the condition was hit, but its WARN severity was
misleading, and its meaning still was obscure to users.

This commit extends the reception of sample data in the session feed and
its accumulation in the local buffer before ZIP archive appends. Any
combination of input and output unit sizes are accepted. It's perfectly
legal for sources to not communicate data for disabled channels, as well
as to communicate wider data images than strictly necessary to simplify
their support for a variety of input formats or device models. Details
are available to users at higher log levels (INFO). Default levels only
communicate fatal conditions (which should be implementation flaws now
exclusively).

The issue reproduces especially well with input formats that are rather
flexible, or device drivers which support a range of devices with many
configurations or models of differing capabilities. The issue was most
recently reported for the OLS driver and an Arduino SUMP firmware. Given
how many input modules and device drivers can feed into a few output
modules, it's assumed that addressing the general issue in a common
location is preferrable over local adjustment of individual input
modules or device drivers. Adjusting both places doesn't harm either,
increases overall robustness.

The implementation results in a negligable runtime overhead for the
regular case of matching unit sizes (a few integer checks). And an
acceptable overhead when the session feed is wider than the srzip
archive's unit size (multiple memcpy() calls where previously was only
one which would have been incorrect without the consistency check). The
code path which needs to apply padding to the output is most expensive,
but the implementation is only as expensive as it needs to be. The added
cost only occurs in the case of mismatches, which were not handled at
all before this change. The combination of extensive diagnostics and
internal consistency checks shall increase robustness and help during
future maintenance.

hantek-dso: eliminate the "forced trigger" option value

Commit c93f113879a0 introduced a hack on top of an unfortunate choice.
It seems counter intuitive to open code a default trigger source on an
arbitrary channel, and have users override it with the "forced" value
to _not_ use a trigger.

The normal approach would be to specify a trigger when a trigger should
be used, and to not specify a trigger when no trigger should be used.

Eliminate the "forced" choice in the trigger_sources[] list. Start with
a not-set value. Accept when a value is specified (a "genuine" choice).
Don't bother adding support to "un-set" the previously specified choice.

This leaves the intuitive support for trigger specs that shall be used,
and only uses triggers when they were specified. Does not provide means
to "un-set" an earlier specified trigger config as the implementation
did before the 2023-09 change, which would be the 2021-02 status.

If the approach implemented here should be considered undesirable, then
a "none" option value should be introduced, something that much better
communicates to users what's happening and what the consequence of a
config choice would be.

This commit also adjusts the "ugh" code path which differed from the
"capture empty" code path. Fixes a resource leak in the config set path.
The "set trigger source" and "set trigger and samplerate" commands don't
agree on the phrase for the trigger source in the wire format. But have
been doing that before the forced trigger introduction, behaviour
remains unchanged here.
