e86a923d50 libudev: monitor - ignore messages from unusual sources
For added protection, ignore any unicast message received on the
netlink socket or any multicast message on the kernel group not
received from the kernel.

4b09a2fc43 avoid leaking netlink socket fd to external programs
The netlink socket is now used by udev event processes. We should take
care not to pass it to the programs they execute. This is the same way
the inotify fd was handled.

116254097a send monitor events back to netlink socket
Instead of of our own private monitor socket, we send the
processed event back to our netlink socket, to the multicast
group 2 -- so any number of users can listen to udev events,
just like they can listen to kernel emitted events on group 1.

b29a5e4ab9 use more appropriate alternatives to malloc()
Use calloc to request cleared memory instead.
Kernel and libc conspire to make this more efficient.

Also, replace one malloc() + strcpy() with strdup().

659353f5a9 replace strerror() usage with threadsafe "%m" format string
strerror() is not threadsafe.  It uses a buffer to build messages of the form
"Unknown error 387689".

syslog() provides a %m format which is equivalent to strerror(errno).
As a GNU extension, this is also accepted by printf and friends.
At least in the current implementation, it is correctly threadsafe.
