Update GCC warning flags and function attributes to GCC 4.7.
* Makefile (WARN): Update to include almost all warning flags.
* plugin-runner.c (getplugin, add_to_char_array, add_argument,
add_environment, set_cloexec_flag,
print_out_password): Add attribute
"warn_unused_result".
(main/parse_opt): Bug fix: Add error checking to --global-env,
--env-for, --plugin-dir, and --config-file, and
make sure errno does not "leak" from unrelated
functions.
* plugins.d/mandos-client.c
(fprintf_plus, debuggnutls, resolve_callback): Add "nonnull"
attribute.
(incbuffer, add_server, init_gpgme): Add "nonnull" and
"warn_unused_result"
attributes.
(pgp_packet_decrypt, init_gnutls_global): - '' -
(init_gnutls_session start_mandos_communication, get_flags): - '' -
(good_flags, good_interface, interface_is_up): - '' -
(interface_is_running, runnable_hook): - '' -
(avahi_loop_with_timeout, bring_up_interface): : - '' -
(safer_gnutls_strerror): Add "warn_unused_result" attribute.
(notdotentries): Set "nonnull", "pure", and "warn_unused_result"
attributes.
(raise_privileges, raise_privileges_permanently, lower_privileges,
lower_privileges_permanently): Set "warn_unused_result" attribute.
(run_network_hooks): Exit child process if it fails to do anything
it needs to do. Make explicit cast to double
when passing float value to asprintf(). Change
return type to void - all callers changed.
(bring_up_interface): Move variables "sd", "ret_errno", and
"ret_setflags" to innermost scope. Bug fix:
Fail if could not get interface flags also in
non-debug mode, and restore old errno
correctly. Print message if could not raise
(or later lower) privileges.
(take_down_interface): Bug fix: When failing because it could not
get interface flags, restore old errno
correctly. Print message if it could not
raise (or later lower) privileges.
(main): Complain if failed to raise or lower privileges. Only run
network hooks or lower privileges if raising privileges was
successful.
