all: move the documentation under _www/doc directory

This also allow the latest/released documentation viewed on
the web user interface under /doc path.

While at it, reformat HTML and CSS files using js-beautify and
JavaScript files using clang-format [1].

-== NAME
-
-rescached.cfg - Configuration for rescached service
-
-
-== SYNOPSIS
-
-/etc/rescached/rescached.cfg
-
-
-== DESCRIPTION
-
-These file configure the behaviour of *rescached*(1) service.
-This section will explain more about each option and how they effect
-`rescached`.
-
-The configuration is using INI format where each options is grouped by header
-in square bracket:
-
-* `[rescached]`
-* `[dns "server"]`
-
-
-== OPTIONS
-
-=== [rescached]
-
-This group of options contain the main configuration that related to
-rescached.
-
-[#wui-listen]
-==== wui.listen
-
-Format:: [host]:port
-Default:: 127.0.0.1:5380
-Description:: The address to listen for web user interface.
-
-[#file-resolvconf]
-==== file.resolvconf
-
-Format:: /any/path/to/file
-Default:: /etc/rescached/resolv.conf
-Description:: A path to dynamically generated *resolv.conf*(5) by
-*resolvconf*(8).
-+
---
-If set, the nameserver values in referenced file will be used as "parent" name
-server if no "parent" is defined in configuration file.
-
-To use this config, you must set either "dnsmasq_resolv", "pdnsd_resolv", or
-"unbound_conf" in "/etc/resolvconf.conf" to point to
-"/etc/rescached/resolv.conf".
-
-For example,
-----
-resolv_conf=/etc/resolv.conf
-name_servers=127.0.0.1
-dnsmasq_resolv=/etc/rescached/resolv.conf
-#pdnsd_resolv=/etc/rescached/resolv.conf
-#unbound_conf=/etc/rescached/resolv.conf
-----
---
-
-[#debug]
-==== debug
-
-Value::
-0::: log startup and errors.
-1::: log startup, errors, request, response, caches, and exit status.
-Format:: 	Number (0 or 1).
-Default:: 	0
-Description:: 	This option only used for debugging program or if user want to
-monitor what kind of traffic goes in and out of rescached.
-
-[#dns_server]
-=== [dns "server"]
-
-This group of options related to DNS server.
-
-[#parent]
-==== parent
-
-Format::
-
-----
-parent  = "parent = " [ scheme "://"] ( ip-address / domain-name ) [ ":" port ]
-scheme  = ( "udp" / "https")
-----
-
-Default::
-* Address: udp://1.1.1.1
-* Port: 53
-Description:: List of parent DNS servers.
-+
-When `rescached` receive a query from client (for example, your browser) and
-when it does not have a cached answer for that query, it will forward the
-query to one of the parent name servers.
-+
-Using UDP as parent scheme, will automatically assume that the server also
-capable of handling query in TCP.
-This is required when client (for example, your browser) re-send the query
-after receiving truncated UDP answer.
-Any query received by `rescached` through TCP will forwarded to the parent
-name server as TCP too, using the same address and port defined in one of UDP
-parent.
-+
-Please, do not use OpenDNS server.
-If certain host-name not found (i.e. typo in host-name), OpenDNS will reply
-with its own address, instead of replying with empty answer.
-This will make `rescached` caching a false data and it may make your
-application open or consume unintended resources.
-+
-To check if your parent server reply the unknown host-name with no answer, use
-*resolver*(1) tool.
-
-Example::
-----
-## Using UDP connection to forward request to parent name server.
-parent = udp://1.1.1.1
-
-## Using DNS over TLS to forward request to parent name server.
-parent = https://1.1.1.1
-
-## Using DNS over HTTPS to forward request to parent name server.
-parent = https://kilabit.info/dns-query
-----
-
-[#listen]
-==== listen
-
-Format:: 	<IP-ADDRESS>:<PORT>
-Default:: 	127.0.0.1:53
-Description:: 	Address in local network where `rescached` will listening for
-query from client.
-+
-If you want rescached to serve a query from another host in your local
-network, change this value to `0.0.0.0:53`.
-
-[#http-port]
-==== http.port
-
-Format:: Number
-Default:: 443
-Description:: Port to serve DNS over HTTP.
-
-[#tls-port]
-==== tls.port
-
-Format:: Number
-Default:: 853
-Description:: Port to serve DNS over TLS.
-
-[#tls-certificate]
-==== tls.certificate
-
-Format:: /path/to/file
-Default:: (empty)
-Description:: Path to certificate file to serve DNS over TLS and HTTPS.
-

-Description:: Path to certificate private key file to serve DNS over TLS and
-HTTPS.

-== NAME
-
-resolver - command line interface for DNS and rescached server.
-
-
-== SYNOPSIS
-
-resolver [-insecure] [-ns nameserver] [-server] <command> [args...]
-
-
-== DESCRIPTION
-
-resolver is a tool to resolve hostname to IP address or to query services
-on hostname by type (MX, SOA, TXT, etc.) using standard DNS protocol with UDP,
-DNS over TLS (DoT), or DNS over HTTPS (DoH).
-
-
-== OPTIONS
-
-`-insecure`::
-+
---
-Ignore invalid server certificate when querying DoT, DoH, or rescached server.
---
-
-`-ns <nameserver>`::
-+
---
-This option define the parent DNS server where the resolver send the query.
-Default to one of "nameserver" in `/etc/resolv.conf`.
-
-The nameserver is defined in the following format,
-
-		("udp"/"tcp"/"https") "://" (domain / ip-address) [":" port]
-
-Examples,
-
-* udp://194.233.68.184:53 for querying with UDP,
-* tcp://194.233.68.184:53 for querying with TCP,
-* https://194.233.68.184:853 for querying with DNS over TLS (DoT), and
-* https://kilabit.info/dns-query for querying with DNS over HTTPS (DoH).
---
-
-`-server <rescached-URL>`::
-+
---
-Set the rescached HTTP server where commands will send.
-The rescached-URL use HTTP scheme:
-
-	("http" / "https") "://" (domain / ip-address) [":" port]
-
-Default to "https://127.0.0.1:5380" if its empty.
