* src/assuan.h.in (_assuan_npth_usleep): Wrap __assuan_usleep.

--

Assuan should support system hooks for nPth before npth_init.

Before the call of npth_init, npth_unprotect and npth_protect do
nothing, whiile npth_usleep may crash.

No use of npth_usleep is better.

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
