Initial set of changes to to enable proper compilation ond operations on ARMv7 32bit platform.

Browse Source 
- added patch to ALSA RAVENNA/AES67 Driver
- switched to CLANG compiler in order to compile the daemon succesfully
- disabled valgind memory check in daemon regression tests for ARM.
Demo and daemon regression test work properly.
Tests have been executed on the BeagleBone® Black board with ARM Cortex-A8 32-Bit and Ubuntu 18.04 distro

The daemon and the demo have been tested on **Ubuntu 18.04** distro on **x86/ARMv7** plattforms and on **19.10** distro on **x86** using:
* Linux kernel version >= 5.0.0
* GCC version >= 7.4 / clang >= 6.0.0 (C++17 support required)
* Linux kernel version >= 4.14.x
* GCC version >= 7.4 / clang >= 6.0.0 (C++17 support required, clang is required to compile on ARMv7)
* cmake version >= 3.10.2
* node version >= 8.10.0
* mpm version >= 3.5.2
* boost libraries version >= 1.65.1
The BeagleBone® Black board with ARM Cortex-A8 32-Bit processor was used for testing ARMv7.
See [Ubuntu 18.04 on BeagleBone® Black](https://elinux.org/BeagleBoardUbuntu) for additional information about how to setup Ubuntu on this board.
The [ubuntu-packages.sh](ubuntu-packages.sh) script can be used to install all the packages required to compile and run the AES67 daemon, the daemon tests and the [demo](#demo). See [PulseAudio and scripts notes](#notes).
