[Buildroot] [PATCH v3 1/1] LIBLO : bump version to 0.29

[Alex B]

From: Alex <alexbaldwinmusic at gmail.com>

Starting from version 0.28, C++ wrappers are provided as well. The configure
script appropriately detects the availability of a C++ compiler so no Buildroot
changes are needed for this.

Building fails with --enable-ipv6 so --disable-ipv6 is needed in CONF_OPTS.
This is known by liblo developers and building without ipv6 support is recomennded.

werror is kept on, so disable this with --disable-werror.

Patch to fix werror about redirect from sys/poll.h to poll.h

Liblo use's atomics, some architectures need explicit linking with libatomic. Added
link to reflect this.

Included hash for license files.

CHANGELOG
-V2
No longer including a patch for liblo/configure. This was the wrong way of dealing with --enable-ipv6.
SHA256 for COPYING file instead of sha1.
Include  # License files comment for clarity.
-V3
disable werror
poll.h redirect patch
link with libatomic when HAS_LIBATOMIC
