This patchset uses more network helpers in test_sock_addr.c, but first of all, patch 2 is needed to make network_helpers.c independent of test_progs.c. Then network_helpers.h can be included into test_sock_addr.c without compile errors.
Patch 1 and patch 2 address Martin's comments for the previous series too.

As Martin mentioned in review comment, there is an existing bug that orig_netns_fd will be leaked in the later "goto fail;" case after open("/proc/self/ns/net") in open_netns() in network_helpers.c. This patch adds "close(token->orig_netns_fd);" before "free(token);" to fix it.

From: Geliang Tang tanggeliang@kylinos.cn
ASSERT helpers defined in test_progs.h shouldn't be used in public functions like open_netns() and close_netns(). Since they depend on test__fail() which defined in test_progs.c. Public functions may be used not only in test_progs.c, but in other tests like test_sock_addr.c in the next commit.
This patch uses log_err() to replace ASSERT helpers in open_netns() and close_netns() in network_helpers.c to decouple dependencies, then uses ASSERT_OK_PTR() to check the return values of all open_netns().

Include network_helpers.h in test_sock_addr.c, use the newly added public helper start_server_addr() instead of the local defined function start_server(). This can avoid duplicate code.
In order to use functions defined in network_helpers.c in test_sock_addr.c, Makefile needs to be updated and <Linux/err.h> needs to be included in network_helpers.h to avoid compilation errors.
