When compiling restorecond with -Wunused, gcc 4.8.4 (from Ubuntu 14.04)
reports the following warnings:
restorecond.c: In function ‘main’:
restorecond.c:208:9: error: ignoring return value of ‘daemon’,
declared with attribute warn_unused_result [-Werror=unused-result]
daemon(0, 0);
^
restorecond.c: In function ‘write_pid_file’:
restorecond.c:106:2: error: ignoring return value of ‘write’,
declared with attribute warn_unused_result [-Werror=unused-result]
(void)write(pidfd, val, (unsigned int)len);
^
If any of these calls returns an error, it is currently silently
discarded. Add a message in order to warn about such an error.

There were several places in the makefiles where LDLIBS or CFLAGS were
supposed to include options to build. They were missing the override
keyword so would be skipped if these vars were set on the make cmdline.
Add the override directive to fix this.

The toolchain automatically handles them and they break cross compiling.
LDFLAGS should also come before object files, some flags (eg,
-Wl,as-needed) can break things if they are in the wrong place)

This makes it possible for static analyzers such as clang's one to
understand that strings_list_add() cannot dereference a NULL pointer in
the following code:
if (!newptr)
exitApp("Out of Memory");
newptr->string = strdup(string);

Decrease loglevel of termination message
(eg. "restorecond[709]: terminated") to LOG_INFO because it is printed
upon normal shutdown of the daemon.

Now that restorecond is separated from policycoreutils, we should not
retain a build dependency on the policycoreutils/setfiles source files.
Fork the restore.[ch] files for restorecond.
