make `getaddrinfo()` and `getnameinfo()` usage consistent

2015-06-17T22:45:02+00:00

Use modern name resolution functions and use them in a consistent
manner.

 * Avoid obsolete `gethostbyname()`, `gethostbyname2()` and `gethostbyaddr()`
 * Maintain consistency in variable names and error messages
 * Leave IDN handling up to name resolution functions

Note: This patch provides a primitive translation of calls to obsolete
functions to calls to modern functions but more changes are needed to
process the whole result lists instead of using just the first result.

Note: This patch skips functions that use jumps to avoid making more
damage than benefits.

ping,rdisc: Optimize checksumming.

2012-11-28T03:02:18+00:00

- On x86{-64}, htons(*(u_char *)w << 8) generates shift 8 bits and
  rotate 8 bits (swap bytes), which does nothing.  This is not good.
- Calculate checksum on properly-aligned buffer, instead of byte-aligned
  buffer.

rdisc_srv,Makefile: Fix build.

2012-11-15T18:21:14+00:00

With "make rdisc_src.o", we got
| rdisc.c: In function 'pr_pack':
| rdisc.c:889:17: error: incompatible types when assigning to type 'struct in_addr' from type 'u_int32_t'
| rdisc.c: In function 'finish':
| rdisc.c:959:7: warning: unused variable 'i' [-Wunused-variable]

With "make rdisc_srv", we got many multiple definition errors because -c was
missing to make rdisc_srv.o.
