Jason A. Donenfeld e975597e72 wg: add wg-quick
This is based on wg-config, but is even easier to use, and now makes
our full tools suite.

Tomasz Torcz f3a1f15186 wg: rename 'bandwidth' to 'transfer' in output
'bandwidth' is a measure of speed, but wg's output shows only the
number of bytes transferred. Thus 'transfer' is a better label.

Jason A. Donenfeld a488f1b084 wg: do not use AI_ADDRCONFIG
Some people run wg(8) using hard coded v6 addresses before interfaces
have v6 addresses, causing getaddrinfo to fail. Since AI_ADDRCONFIG
doesn't actualy change the sorting, but just the queries made, we don't
really need AI_ADDRCONFIG anyway, since we're always only taking the
first result.

Jason A. Donenfeld 971c792ba9 wg: everybody hates automatic stripping
I happen to like it, but package managers don't. The GNU standard [1]
says there should be a separate install-strip target. I don't like
duplicating code like that. So, instead, I'll just remove stripping all
together.

Jason A. Donenfeld 1b9a83c852 c: specify static array size in function params
The C standard states:

  A declaration of a parameter as ``array of type'' shall be adjusted to ``qualified pointer to
  type'', where the type qualifiers (if any) are those specified within the [ and ] of the
  array type derivation. If the keyword static also appears within the [ and ] of the
  array type derivation, then for each call to the function, the value of the corresponding
  actual argument shall provide access to the first element of an array with at least as many
  elements as specified by the size expression.

By changing void func(int array[4]) to void func(int array[static 4]),
we automatically get the compiler checking argument sizes for us, which
is quite nice.

  if (bind(fd, (struct sockaddr *)&addr, sizeof(addr)) < 0)
      exit(1);

  for (;;) {

       * allocate. Note on BSD you can instead use ioctl(fd, FIONREAD, &len). */

          continue;
