As recently fixed in sockstat (9934558460), having tests/Makefile
include files from the parent directory with SRCS= ../foo.c results
in a race condition as the parent build and the tests build try to
produce the same object file but contain different paths.
Use .PATH to tell make to find sockstat.c in the parent directory
but place the object file in the current object directory.

The ping tests were originally broken by an unrelated isue that
is now fixed ( 2926c25942 ).
THanks to kp@ for fixing the test and Jose Luis Duran for pinting it out.
This reverts commit 7bc0cb91a2.
Scapy 2.6.0 now appears to parse the IPOption during construction, and it then
gets confused at a single-byte option. IP Options typically contain at least a 1
byte type and 1 byte length. Avoid this by just returning the raw bytes, rather
than an IPOption object.

Traditionally, ping returned exit code EX_NOHOST if a DNS lookup failed.
That is still the case for the legacy code in the new merged ping, but
not for IPv6 targets, nor when a DNS lookup is performed in order to
determine which version of the tool to invoke.
While here, also make sure that the error message is consistent.

Very early on, the Src/Dst IP addresses were printed in hex notation
(%08x), which will always be 8-characters wide. It was later changed to
use a dot-decimal notation. Depending on the IP address length, the Src
and Dst headers may require a different padding. Use the source and
destination IP lengths as padding for the headers.
Also, print an Opts (options) header, if there are options present. It
has been abbreviated to Opts to match the length of the previous Data
header, removed in ef9e6dc7ee.
Print the header info such that no trailing spaces are produced. As
some git workflows may automatically trim them, and make the tests fail
(see 25b86f8559).

When an echo reply packet is received, the data is compared with the
sent data. When a wrong byte is detected the command displays a report
with the differences.
The first row (the first 8-bytes of data after the ICMP header) should
include the time stamp (if data is at least 8-bytes), this value is not
taken into consideration for the comparison. The remaining rows
represent the data (padded pattern) received/sent, with each byte being
compared for differences.
Print the space before (not after), to add an extra space after cp:/dp:
for better readability when the first time stamp octet is not
zero-padded, and to remove trailing spaces in the output.

This is a first step towards a unification/simplification of ping/ping6
(internally). The end goal is to produce a standardized user-facing
output.
Before (ping6):
PING6(56=40+8+8 bytes) 2001:db8::1 --> 2001:db8::2
16 bytes from ::1, icmp_seq=0 hlim=64 time=0.168 ms
16 bytes from ::1, icmp_seq=1 hlim=64 time=0.068 ms
--- 2001:db8::2 ping6 statistics ---
round-trip min/avg/max/std-dev = 0.068/0.118/0.168/0.050 ms
After (ping6):
PING(56=40+8+8 bytes) 2001:db8::1 --> 2001:db8::2
16 bytes from ::1, icmp_seq=0 hlim=64 time=0.168 ms
16 bytes from ::1, icmp_seq=1 hlim=64 time=0.068 ms
--- 2001:db8::2 ping statistics ---
round-trip min/avg/max/stddev = 0.068/0.118/0.168/0.050 ms
This has the nice side-effect of adding units to SIGINFO's statistics,
as printing numbers without units may not be of much help. Also
mentions the fact that these times are round-trip.
Before (ping/ping6 SIGINFO):
2/2 packets received (100.0%) 0.068 min / 0.118 avg / 0.168 max
After (ping/ping6 SIGINFO):
--- <ipv4/ipv6 address> ping statistics ---
2 packets transmitted, 2 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 0.068/0.118/0.168/0.050 ms
In the case of a SIGINFO, the output will be printed to stderr, for both
ping and ping6.

Avoid calculating the square root of negative zero, which can easily
happen on certain architectures when calculating the population standard
deviation with a sample size of one, e.g., 0.01 - (0.1 * 0.1) =
-0.000000.
Avoid returning a NaN by capping the minimum possible variance value to
zero (positive).
In the future, maybe skip reporting statistics at all for a single
sample.
