- fix `error()` function documentation
- change error message format order to `msg: strerror`
- change `xxx() failed` messages to just `xxx()`

Introduce a new socket module which provides bindings for the BSD sockets
API to ucode scripts.
Example usage:
import * as socket from 'socket';
let sk = socket.create(socket.AF_INET, socket.SOCK_STREAM);
sk.connect("192.168.1.1", 80);
sk.send("GET / HTTP/1.0\r\n\r\n");
print(sk.recv(4096));
sk.close();

The reorder() function takes no `name` parameter, this was a copy-paste
error in the documentation.

This is needed when asynchronously processing requests via uloop, e.g.
using uclient.
Example script:
let libubus = require("ubus");
let uloop = require("uloop");
uloop.init();
let ubus = libubus.connect();
ubus.publish("test", {
test: {
call: function(req) {
req.defer();
uloop.timer(1000, () => {
req.reply({ msg: "Hello, world!" }, 0);
});
},
args: {}
},
});
uloop.run();
uloop.done();

Make all functions clear the last error information on success in order to
ensure that `error()` never reports stale information.

Use the same RX buffer size which iproute2 uses as default, in order to
avoid (or rather, delay as much as possible) ENOBUFS conditions when
receiving a large burst of netlink notifications.
Signed-off-by: Jo-Philipp Wich <jo@mein.io>

Once we're notified about pending data on the netlink event socket,
try to receive as much messages as possible in order to empty the socket
buffer. In contrast to the previous implementation which received one
message per epoll read notification, this avoids some premature ENOBUFS
situations when a huge burst of messages arrives, e.g. due to kernel
side GC runs on the neighbor table.
Since libnl's nl_recvmsgs*() functions do not expose the underlying
-1 error returned by the recvmsg() calls, we need to indirectly check
for errors through errno variable, so clear it out both before the
recvmsgs() call and after successfully completing a message reception
callback invocation.

Only store the callback reference in the registry once the listener
context was successfully initialized, to avoid keeping a lingering
entry when invalid parameters are passed.

- The expected length was incorrect
- An incorrect MCS MAP index was accessed
- The maximum MCS index number were wrong
Signed-off-by: Jo-Philipp Wich <jo@mein.io>

The length constraint of 16 byte was incorrect, the attribute is 8 bytes
long; two bytes for the RX MCS set, two bytes for the highest RX rate,
two bytes for the TX MCS set and two bytes for the highest TX rate.

When the VM instance loading the uloop module has signal dispatching
enabled, implicitly register the signal pipe as file descriptor in the
global uloop and dispatch received signals to the VM instance.
This ensures that the respective managed ucode signal handlers are
invoked immediately and not just after `uloop_run()` returns.
Also end the uloop in case any invoked signal handler threw an
exception, to match the expected behaviour with other kinds of
callbacks.

Reportedly, automatic conversion of the `isatty()` int result value to
a bool does not work correctly on PPC. Explicitly compare the result
value with `1` to infer the boolean result value.

A uci commit operation may invalidate the package pointer, leading to an
infinite loop while iterating the packages to commit.
Refactor the code to first build a string list of configurations, then
iterating it in order to avoid the iterator invalidation.
While we're at it, also allow restricting save and revert operations to
single configs, which was rejected as invalid before.
