[Buildroot] [PATCH v11 01/26] package/freeswitch: new package

[Bernd Kuhls <bernd.kuhls@t-online.de>]

This commit adds freeswitch without any configured modules and with a
minimal set of non-optional dependencies. All other dependencies and
modules will be added by further patches in this series.

PLease note that freeswitch source repo bundles some libraries which are
also available as buildroot packages. The freeswitch build system does
not allow to use system libraries in these cases:

apr, apr-util, libsrtp, libvpx, libyuv, sofia-sip, tiff

The reason are patches to these packages by the freeswitch project which
are not yet upstream. There is an open JIRA report for this situation:
https://freeswitch.org/jira/si/jira.issueviews:issue-html/FS-353/FS-353.html

More historic infos can be found here:
http://article.gmane.org/gmane.comp.telephony.freeswitch.devel/2715
https://freeswitch.org/the-missing-link/

In the 1.6.7 version bump libvpx & libyuv were also moved in-tree:

+Subject: [PATCH 1/1] Makefile.am: fs_cli needs libzrtp.a
+
+Compiling freeswitch sometimes shows a strange linking error:
+
+libs/libzrtp/third_party/bnlib/libbn.a(lbnmem.o): In function `lbnMemWipe':
+/home/bernd/buildroot/br7_freeswitch/output/build/freeswitch-1.6.6/libs/libzrtp/third_party/bnlib/lbnmem.c:69: undefined reference to `zrtp_memset'
+libs/libzrtp/third_party/bnlib/libbn.a(lbnmem.o): In function `lbnMemAlloc':
+/home/bernd/buildroot/br7_freeswitch/output/build/freeswitch-1.6.6/libs/libzrtp/third_party/bnlib/lbnmem.c:78: undefined reference to `zrtp_sys_alloc'
+libs/libzrtp/third_party/bnlib/libbn.a(lbnmem.o): In function `lbnMemFree':
+/home/bernd/buildroot/br7_freeswitch/output/build/freeswitch-1.6.6/libs/libzrtp/third_party/bnlib/lbnmem.c:87: undefined reference to `zrtp_sys_free'
+
+Adding libuuid as dependency fixes the problem although there is no
+connection between libzrtp and libuuid.
+
+Apparently bnlib depends on three symbols from libzrtp. Adding libzrtp.a
+to LIBS adds it to the linking command of fs_cli which fixes the bug.
