* bmg160 SPI devices.
* HDC100x humidity sensors
* Holt HI-8435 threshold detector

  detectors on devices with out interrupt support.  First user is the holt
  comparator.
* chemical concentration and resistance channel types.

New driver functionality
* vf610
  - buffer support.
  - followup coccinelle warning fix.

Core rework

  - move buffer implementations to a new subdirectory
* percolate the error code form iio_event_getfd out to userspace
  rather than giving a missleading error later on.

Cleanups
* adddac drivers
  - use BIT macro where appropriate.

    any more and it avoids breaking PREEMPT_RT builds due to the use
    of a spinlock between the hardirq and the thread.

Tools
* event-monitor
  - report unsupported events.  We keep expanding what can come from drivers
    so give a helpful error if one turns up in an out of date userspace
    program.
* generic-buffer
  - helpful message about needing to enable a channel to start the buffer.

In this patch, I'm converting them to time64_t and timespec64,

can probably be avoided by a larger restructuring of the code, but
