Rename options for unifying option parsing with ping

The renaming is done so that names of equivalent options between ping and ping6 are the same, nonequivalent are different.

sbin/ping6/ping6.8

32 ↗

(On Diff #61052)

You should update this date.

43 ↗

(On Diff #61052)

This line was sorted alphabetically before. You should try to keep it that way.

IPv6 hoplimit is functionally equivalent to IPv4 TTL, so they can use the same flag.

312 ↗

(On Diff #61052)

I suggest changing -w to -y to preserve the current symmetry between -w and -W. You would of course need to choose a different letter for "Generate ICMPv6 Note Information supported"

sbin/ping6/ping6.c

437 ↗

(On Diff #61052)

What was the base revision from which you generated this diff? There should've been a case 'H' here.

Update date in the manual page.
Sort options in the SYNOPSIS section of the manual page alphabetically.
Use -m for hoplimit.
Change -w to -y.
Sort the getopt string alphabetically.
Sort options in the usage message alphabetically.
Reflect change of the -X option name to the test.

One more thing: you should normally add an entry in UPDATING letting people know that the options have changed so they can update their scripts. I'll go ahead and write it this time.
