Big cleanup in config help and description

2017-01-10T13:58:54+00:00

Redundant help texts (one which only repeats the description)
are deleted.

Descriptions and help texts are trimmed.

Some config options are moved, even across menus.

No config option _names_ are changed.

httpd: fix address family for reverse proxy client socket

2017-01-08T14:14:38+00:00

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).

httpd: explain why we use sprintf and why it should be fine

2016-11-22T01:23:35+00:00

While at it, fix a pathological case where it is not fine:
-r REALM with some 8-kbyte long REALM would overflow the buffer.
