This patch removes inline functions from iio_utils.h in order to clean the
code. iio_utils.c contains the implementation of the functions used by
iio_event_monitor.c, lsiio.c or generic_buffer.c and iio_utils.h contains
the declarations of these functions.
Since iio_utils.h is modified, generic_buffer.c and iio_event_monitor.c
must include stdlib.h.

By introducing IIO_EV_TYPE_CHANGE, IIO_EV_TYPE_INSTANCE becomes redundant.
The effect of IIO_EV_TYPE_INSTANCE can be obtained by using IIO_EV_TYPE_CHANGE
with IIO_EV_INFO_VALUE set to 1.
Remove all instances of IIO_EV_TYPE_INSTANCE and replace them with
IIO_EV_TYPE_CHANGE where needed.

A step detector will generate an interrupt each time N step are detected.
A device that has such pedometer functionality is Freescale's MMA9553L:

Introduce IIO_EV_TYPE_CHANGE event type for events that are generated

We already do have the length field in the struct iio_buffer which is
expected to be in sync with the current size of the buffer. And currently
all implementations of the get_length callback either return this field or a
constant number.
This patch removes the get_length callback and replaces all occurrences in
the IIO core with directly accessing the length field of the buffer.

There haven't been any users of the get_bytes_per_datum() callback for a
while. The core assumes that the number of bytes per datum can be calculated
based on the enabled channels and the storage size of the channel and
iio_compute_scan_bytes() is used to compute this number. So remove the
callback.

Some IIO devices do not use the triggers. This patch makes trigger setting
conditional so generic_buffer can be used when triggers are disabled.

This was originally reported by Craig Markwardt on Zubair Lutfullah's
blog and Zubair forwarded it to linux-iio@vger.kernel.org. No email
address known.
The code first counted the number of enabled channels, then created an
array to hold information about them. The code that filled this array then
stored whether a given element was enabled inside the array. Curriously
this element was never used. Craig's patch added a local temporary variable
to avoid the buffer overrun. Jonathan then removed the original enabled
element of the structure as it was not needed at all.
