a8e0b2e8ab Remove rexecd(8), a server that implements a particularly insecure 
method of executing commands remotely.  There are no rexec clients in
the FreeBSD tree, and the client function rexec(3) is present only in
libcompat.  It has been documented as "obsolete" since 4.3BSD, and its
use has been discouraged in the man page for over 10 years.

ad0fab44e2 - Remove padding for ABI compatibility of n_net member from struct 
netent.
- Change 1st argument of getnetbyaddr() to an uint32_t on 64 bit
  arch as well to confirm to POSIX-2001.

These changes break ABI compatibility on 64 bit arch.
There is similar padding issue for ai_addrlen of struct addrinfo.
However, it is leaved as is for now.

036ae3dd79 - The ai_addrlen of a struct addrinfo used to be a size_t, per 
RFC 2553.  In XNS5.2, and subsequently in POSIX-2001 and RFC
  3493, it was changed to a socklen_t.  And, the n_net of a
  struct netent used to be an unsigned long integer.  In XNS5,
  and subsequently in POSIX-2001, it was changed to an uint32_t.
  To accomodate for this while preserving ABI compatibility with
  the old interface, we need to prepend or append 32 bits of
  padding, depending on the (LP64) architecture's endianness.
- Correct 1st argument of getnetbyaddr() to uint32_t on 32
  bit arch.  Stay as is on 64 bit arch for ABI backward
  compatibility for now.

Fix the matchlen() function so that it handles the IPv4 (AF_INET)
case correctly.  Until now it has been treating IPv4 addresses
as if they were IPv6 which could lead to corruption errors.

2c08ac2b38 - do validation check and IPv4-mapped IPv6 address handling before 
any query.
- don't query against IPv6 link-local address.
- use IN6_IS_ADDR_V4{MAPPED,COMPAT} macros.
- use memcpy() instead of bcopy().
