Fail to build and use on FreeBSD

[fblr]

It is not possible to build and install uamqp on FreeBSD because of 3 different build errors in the bundled azure-uamqp-c.

Workaround: export CFLAGS="-DUSE_OPENSSL -D__APPLE__ -DTCP_KEEPINTVL=512 -DTCP_KEEPALIVE=0x0008" && pip install uamqp

Build errors:

• USE_OPENSSL is undefined, so "azure_c_shared_utility/tlsio_openssl.h" is not included and build failed on deps/azure-c-shared-utility/adapters/platform_linux.c
• Functions destroy_network_interface_descriptions, create_network_interface_description, set_target_network_interface etc from deps/azure-c-shared-utility/adapters/socketio_berkeley.c are linux specific and cannot be built on FreeBSD. But it looks like they, at first, are not required for uamqp, then, same issue exists for macOS, so all these functions are inside #ifndef APPLE #endif. So it is enough to declare APPLE to fix this error. It seems another bsd specific ifndef should be added.
• And the last error came from undefined TCP_KEEPINTVL & TCP_KEEPALIVE. TCP_KEEPINTVL is defined in netinet/tcp.h, while TCP_KEEPALIVE does not exist, there is SO_KEEPALIVE

Has anyone had success installing UAMQP on BSD11? I tried the workaround above but keep getting compile errors.

/tmp/pip-install-jhr0vii1/uamqp/src/vendor/azure-uamqp-c/deps/azure-c-shared-utility/adapters/platform_linux.c:39:12: error: implicit declaration of function 'tlsio_openssl_get_interface_description' is invalid in C99 [-Werror,-Wimplicit-function-declaration] return tlsio_openssl_get_interface_description(); ^ /tmp/pip-install-jhr0vii1/uamqp/src/vendor/azure-uamqp-c/deps/azure-c-shared-utility/adapters/platform_linux.c:39:12: error: incompatible integer to pointer conversion returning 'int' from a function with result type 'const IO_INTERFACE_DESCRIPTION ' (aka 'const struct IO_INTERFACE_DESCRIPTION_TAG ') [-Werror,-Wint-conversion] return tlsio_openssl_get_interface_description(); ^~~~~~~~~ 2 errors generated.

When I then add the above-suggested CFLAGS I get this failure:
