src/liboping.c: ping_receive_all: Clear the timer when a FD signals an error.
The loop likely never ends if the error isn't handled, so the least we
can do is ignore the file descriptor in the future.

oping: Temporarily drop privileges if supported by the system.
This tries to solve the read-from-any-file-issue more elegantly by
dropping privileges first thing after start-up and regaining privileges
just to open the sockets.
This has the advantage that the "-f" option is available for all users
again and files are opened according to *their* permissions.
Systems not supporting the _POSIX_SAVED_IDS feature still behave as
before, i. e. if real and effective user IDs don't match, only "-" may
be specified as input file.

src/liboping.c: Fixed argument verification.
ping_iterator_get_info()'s 'buffer' argument _may_ be NULL, since the user
might only be interested in the size of the (to be) returned value. If
'buffer' is NULL, '*buffer_len' should be 0, though, to make sure nothing gets
written to 'buffer'.
This bug was introduced in commit 9ae85a09d919777c9be52e55b23c08bf2c8c1d0e.

Merge branch 'liboping-1.2'
src/oping.c: Added -D <interface name> command line option.
This option sets the outgoing network device to use.
I decided not to reuse the -I command line option for that purpose (which is
what GNU ping is doing), for the following reasons:
* In theory, an interface name could be confused with a host name.
* Imho, it's better to specify things explicitly.
* This approach is more flexible.

Added support for PING_OPT_DEVICE.
This option may be used to set the outgoing network device to be used. The
value passed must be a char-pointer to a null-terminated string specifying an
interface name (e.g. eth0).
Please note that this might not be supported by all operating systems. In that
case, ping_setopt() sets the error to "operation not supported".

stupid that might be.

src/liboping.c: Let ping_setopt() return -1 if 'value' is NULL.
The manpage states that 'value' must not be NULL. Anyway, imho, it's still
better to avoid segfaults inside a library.

src/liboping.c: Fix some format strings.
src/liboping.c: Fixed the handling of multiple hosts.
ping_receive_all() used to always pass the first host object to
ping_receive_one() which used that host object to determine the expected
address family. Thus, when pinging v4 and v6 hosts in parallel, some of them
would have never been considered but assumed to be timed out.
While at it, the code has been clarified in regard to matching an ECHO_REPLY
with the appropriate host object.

Instead, reset the value of all host object in ping_receive_all().
ping_receive_one() does not necessarily get a pointer to the host object for
which we receive a reply, since ICMP messages may be received on _any_ raw
socket.
