Add and use std_session_send_df_header().
This is a small helper function which sends the SR_DF_HEADER packet that
drivers usually emit in their hw_dev_acquisition_start() API callback.
It simplifies and shortens the hw_dev_acquisition_start() functions
quite a bit.
It also simplifies the input modules which send an SR_DF_HEADER packet, too.
This patch also automatically removes some unneeded malloc/free in some
drivers for the 'packet' and 'header' structs used for SR_DF_HEADER.

hw_dev_close(): Move common checks to wrapper.
Check the relevant arguments for != NULL before calling the actual
driver-specific function, so that the driver can safely assume those
arguments are non-NULL. This removes the need to duplicate these
checks in every driver.
This patch might also work for a number of other Brymen models
-- 859(a), 867, 869---
including their respective rebadges from Greenlee, Extech, and Amprobe.

Also, do some minor whitespace and consistency improvements.

Also, change one SR_ERR to the more correct SR_ERR_MALLOC, and assign
sr_ctx in the rigol-ds1xx2's hw_init() function, like all the other
drivers do.

New driver API function: config_list()
This takes an sr_config key and returns a list of possible values for
that key to be submitted with config_set(). The format of the list and
its contents is dependent on the key.
This will replace the SR_DI_* keys that returned such a list before,
such as SR_DI_SAMPLERATES.

Use new SR_DF_META packet.
Since input modules determine a samplerate by reading from their
file format (or having it overridden with an option), they need
to pass this up to the frontend.

drivers: use new sr_config struct
Sending an SR_DF_META packet at the start of every stream is not
mandatory; the frontend should ask for what it needs, and any extra
information the driver wants to send will come in due time.

Remove non-error hw_info_get() messages.
Currently hw_info_get() can receive requests for entries (info_id) that
the specific driver doesn't support. That is (right now) a valid
use-case and not an error (might change later, though).
Thus, for now, don't output messages for such requests at all (certainly
not as sr_err() where they show up in e.g. sigrok-cli output per default).

alsa: Silence ALSA scanning process.
Errors while opening or configuring ALSA devices during scan for devices
should not be shown by default (i.e., no sr_err() usage). Non-working
or non-accessible devices (due to permissions or other reasons) will
simply not show up in frontends. Use sr_dbg() instead of sr_err().
Fix the bare minumum of whitespace/indentation/coding-style via
automatic 'indent' run, followed by some minor manual fixes.
Some more fixes and cleanups might follow later.

Add gnuplot_rigol_ds1xx2.gpi gnuplot script.
This is a very simple gnuplot script for testing the Rigol DS1xx2 driver.
It currently has various issues and limitations (e.g. only one channel
is displayed, the scaling is not usable, and so on) to be fixed later.
