[Buildroot] [PATCH] libiio: bump to version 0.15

[Alexandru Ardelean]

This change bumps libiio, to version 0.15.
This version is currently the most stable version in the series. It
contains several fixes over 0.14.

0.16 & 0.17 have been released but they have some issues with backwards
compatibility, so they are not yet recommended.

Changelog for version 0.15 (over 0.14).

0.15 contains a fix that should also be added into the latest LTS.
buildroot LTS contains version 0.14

Question:
 - is it ok to port this change to the LTS (2019.02) ?
 - do we cherry-pick the patches from 0.15 to put on top of 0.14 ?

The important patches would be ~12.
The really important patches would be fewer (needs more digging into).

How do patches for LTS versions get marked/sent ?
(Or how is the protocol for sending patches to LTS; I haven't found
anything yet to suggest how to do it).

Thanks
Alex
