First round of new drivers, functionality and cleanups for IIO in the 3.13 cycle

A number of new drivers and some new functionality + a lot of cleanups
all over IIO.

New Core Elements

1) New INT_TIME info_mask element for integration time, which may have
   different effects on measurement noise and similar, than an amplifier
   and hence is different from existing SCALE.  Already existed in some
   drivers as a custom attribute.

2) Introduce a iio_push_buffers_with_timestamp helper to cover the common
   case of filling the last 64 bits of data to be passed to the buffer with
   a timestamp.  Applied to lots of drivers. Cuts down on repeated code and
   moves a slightly fiddly bit of logic into a single location.

3) Introduce info_mask_[shared_by_dir/shared_by_all] elements to allow support
   of elements such as sampling_frequency which is typically shared by all
   input channel...
