[PATCH gwhttpd 0/2] Two gwhttpd fixes

[Ammar Faizi <ammarfaizi2@gnuweeb.org>]

Hi,

This small series contains two fixes for gwhttpd.

## Patch 1
Yonle reported that he is getting an error on bind():

  Address family not supported by protocol

This doesn't mean that Yonle's device doesn't support IPv4, but it's
because we don't explicitly set the sa_family to AF_INET. This will
happen to work just fine only on a platform where `AF_INET == 0` since
we have a prior memset() call that zeroes the whole struct sockaddr_in.

On platforms that have `AF_INET != 0`, this will break. Fix this by
simply setting the `saddr.sa_family` to AF_INET at initialization.

## Patch 2
When Yonle reported an issue about error on bind(), he attached an
strace output and it has many EBADF errors like this:

  close(0) = 0
  close(0) = -1 EBADF (Bad file descriptor)
  close(0) = -1 EBADF (Bad file descriptor)
  close(0) = -1 EBADF (Bad file descriptor)
  close(0) = -1 EBADF (Bad file descriptor)
  close(0) = -1 EBADF (Bad file descriptor)
  ...

This happens because all sess[i].fd is set to 0 at initialization while
the destructor is supposed to close the file descriptor when it's not
equal to -1. Fix this by setting all file descriptor fields to -1 at
initialization.
