082d8d6623 Noux/net: refactoring of Socket_io_channel
The Socket_io_channel class now uses the Io_channel_backend to provide
the network related methods. In addition the Socket_io_channel_registry
was replaced with a simpler implementation which uses Io_receptors to
unblock I/O channels from the callback-function of lwip.

837f913094 Noux: more useful gettimeofday() implementation
There are certain programs that need gettimeofday(), e.g.
network-related tools like ping(1) etc. but also filesystem-related
programs like find(1) etc. and of course time-related programs like
date(1).

As there is currently no interface in Genode for actually using clock
devices like RTC on x86 (though there is a driver for it) we "abuse"
the timeout_scheduler thread to at least provide flow-of-time.

Noux: add clock_gettime() implementation

For now, only CLOCK_SECOND is supported.

Noux: add utimes() dummy

Fixes #401

57b0490fc6 Noux: remove {get,free}addrinfo
This dead-code will not be needed in the future because we now use
libc_resolv.

a77c3dffd0 Noux: add user information support (struct passwd)
There are certain programs which need the information that is stored in
'struct passwd'. This commit introduces configurable user information
support to NOUX.

One can set the user information via <user> in NOUX config:

! <config>
!   <user name="baron" uid="1" gid="1">
!     <shell name="/bin/bash" />
!     <home name="/home" />
!   </user>
! [...]
! </config>

When <user> is not specified default values are used. Currently these
are 'root', 0, 0, '/bin/bash', '/'.

Note: this is just a single user implementation because each Noux instance
has only one user or rather one identity and there will be no complete
multi-user support in Noux. If you need different users, just start new
Noux instances for each of them.

6d8a7c0cc4 Initial version of networking support for Noux
Noux/net adds network functionality to noux. Currently most basic
network related system calls including 'accept', 'bind', 'connect',
'listen', 'recv', 'send', 'shutdown', and 'socket' are implemented by
wrapping lwip's network functions.

At the moment noux/net is rarely usable, though it is possible to
use netcat to send a message to a netcat server which listen on a
given port in noux/net.
