This function would have failed for any value >= 1000000 because the
nsec field is limited to 999999999 and the function fails for larger
values.

* src/assuan-socket.c (INADDR_LOOPBACK): Define.

--

INADDR_LOOPBACK is not defined in some systems.  When defined, its
byte-order is not clearly defined in any specifications.  So, best
portable way is not to use the macro INADDR_LOOPBACK at all but use
0x7f000001 directly.

Nevertheless, for systems which use libassuan, it's host byte-order.
So, adding the definition works.

Not defining this leads to compilation errors or superfluous warnings

We plan to move more code into libgpg-error/gpgrt anyway thus this is
a good start which also fixes this bug:

The assuan_sock_connect_byname may eventually be extended to work
without Tor or SOCKS by using getaddrinfo.  Or we move that all to
libgpgrt (aka libgpg-error).

A future extension might be a new assuan_sock_direct_connect call
takes the hostname as a string and returns a new socket.  This allows
the proxy to do the resolving.  However, in the long term these socket
wrapper should be moved to libgpgrt (aka libgpg-error).
