47990f37d7 dde_bsd: update audio driver to OpenBSD 5.9
In addition to updating the contrib sources the driver now uses the
new Component API and will report the internal mixer state.

Reporting of the mixer state is enabled by adding the 'report_mixer'
attribute to the drivers configuration and setting its value to 'yes'.

The following snippets illustrates the format of the report:

!<mixer_state>
!  <mixer field="inputs.beep" value="108"/>
!  <mixer field="outputs.hp_sense" value="plugged"/>
!  <mixer field="outputs.master" value="128,128"/>
!  <mixer field="outputs.mic_sense" value="unplugged"/>
!  <mixer field="outputs.spkr_muters" value="hp,mic"/>
!</mixer_state>

The mixer state may expose other mixer fields as well, depending on the
used sound card. The naming scheme of the attributes intentionally
matches the naming scheme of OpenBSD's mixerctl(1) program.

Each 'mixer' node can be used to configure the audio driver by using it
in its configuration, e.g.:

!<config report_mixer="yes">
!  <mixer field="outputs.master" value="255,255"/>
!</config>

This configuration will set the output volume to the highest possible
value. Although it is now also possible to update the configuration
at run-time it should not be done while the driver is currently playing
or recording because it may provoke the generation of artefacts.

Fixes #1973.

ed52d5a211 Introduce 'spec' subdirectories to outline aspects
Instead of holding SPEC-variable dependent files and directories inline
within the repository structure, move them into 'spec' subdirectories
at the corresponding levels, e.g.:

  repos/base/include/spec
  repos/base/mk/spec
  repos/base/lib/mk/spec
  repos/base/src/core/spec
  ...

Moreover, this commit removes the 'platform' directories. That term was
used in an overloaded sense. All SPEC-relative 'platform' directories are
now named 'spec'. Other files, like for instance those related to the
kernel/architecture specific startup library, where moved from 'platform'
directories to explicit, more meaningful places like e.g.: 'src/lib/startup'.

Fix #1673

49dd9242f7 dde_bsd: add audio drivers ported from OpenBSD
These audio drivers enable support for Intel HD Audio (Azalia) and
Ensoniq AudioPCI (ES1370) compatible soundcards. They are ported
from OpenBSD 5.7.

Fixes #1498.
