The peer simply does not return anything. It closes its connection.
Probably it detects wget closing its writing end: shutdown(3, SHUT_WR).
The point it, closing write side of the socket is _valid_ for HTTP.
wget sent the full request, it won't be sending anything more:
it will only receive the response, and that's it.

When httpd proxies a request to another server, it first creates
an AF_INET socket, then resolves the server name to a sockaddr,
then connects to it. This fails if the server name resolves to
an IPv6 address.
This patch ensures that the socket is created with the correct
address family (AF_INET6 if the server resolves to an IPv6 address
and AF_INET otherwise).

Run the namelookup from the main loop so a misspelled first ntp server
name does not block everything forever.
This fixes the following situation which would block forever:
$ sudo ./busybox ntpd -dn -p foobar -p pool.ntp.org
ntpd: bad address 'foobar'
ntpd: bad address 'foobar'
ntpd: bad address 'foobar'
...
New behavior:
ntpd: bad address 'foobar'

Commit a8c696bf09 makes ifup and ifdown
individually selectable, but forgets to update the dependency to
IFUPDOWN_UDHCPC_CMD_OPTIONS, so it is not selectable anymore.
This patch fixes the dependency by checking for IFUP or IFDOWN, instead
of the obsolete IFUPDOWN.
Also, it drops dependency on UDHCPC: udhcpc on the target system
does not have to come from the _same_ binary.

Linux kernel, starting from 2.6.19 allows ip table ids to have 32-bit values.
In order to preserve compatibility, the old 8-bit field: rtm_table is still
in use when table id is lower than 256.
Add support for the 32-bit table id (RTA_TABLE attribute) in:
- ip route print
- ip route modify
- ip rule print
- ip rule modify
Add printing of table ids to ip route.
Changes are compatible with the mainline iproute2 utilities.
These changes are required for compatibility with ConnMan, which by default
uses table ids greater than 255.

Here, not handling the error is would just eat one input 0xff char.
Correct handling would need even more corner case handling,
as-is buggy handling corrupts the buffer.
Since we just been told by kernel that pty is ready,
EAGAIN should not be happening here anyway.

If a write to pty is short, remove_iacs() can be run on a buffer repeatedly.
This, for example, can eat 0xff chars (IACs, in telnet terms).
Rework the logic to handle IACs in a special "write to pty" function.
