[OpenWrt-Devel] [PATCH] network/services/uhttpd: Add Basic Auth config

[openwrt at daniel.thecshore.com]

From: Daniel Dickinson <openwrt at daniel.thecshore.com>

We add an 'httpauth' section type that contains the options:

instance: Which uhttpd config section the auth is associated with
prefix: What virtual or real URL is being protected
username: The username for the Basic Auth dialogue
password: Hashed (crypt()) or plaintext password for the Basic Auth dialogue

If instance is not specified auth section applies to
all instances of uhttpd; if instance is specified
the auth section only applies to the uhttpd config
section with the same name as specified with the
instance option.
