9b936dd120 nic_router: packet verbose at detached interfaces
The 'verbose packets' output previously was not generated for Interfaces
without a domain. But this is desirable as the router nonetheless
receives packets at such interfaces. This is now fixed and such output
is simply prefixed with a "[?]" denoting that the interface has no
domain.

4dc8f6dca4 nic_router: fix missing IPv4.ECN initialization
We missed to zero-out the ECN field in IPv4 packets. We don't use the ECN
field but there might be old data left in the packet RAM allocated by the
NIC packet streams. If we don't zero-out ECN it might leak old data.

9c6b720ec1 Notification support for the VFS library
Add a new 'Vfs_watch_handle' type to the VFS interface. This handle type
will pass a handle context up through the I/O handler to the application
when a notification event occurs.

Watch support implemented for RAM and File_system plugins, all other
file-systems return WATCH_ERR_STATIC by default.

Test at run/fs_rom_update_ram and run/fs_rom_update_fs.

81e55e8901 gems: TrueType VFS plugin
This commit introduces a VFS plugin that exposes the glyphs and
metadata of a TrueType font as a pseudo file system. The TTF font data
is obtained from the VFS. The resulting pseudo file system is a
directory that contains the files 'glyphs', 'baseline', 'max_width',
and 'max_height'.

The counter part of the plugin is the 'Vfs_font' class that implements
the 'Text_painter::Font' interface by accessing the pseudo file system
as provided by the TTF VFS plugin.

c5066a7317 Make gems/vfs.h utils fit for use in VFS plugins
This patch enhances the VFS access utilities of gems/vfs.h to be usable
with a prior created root directory. It also adds a
'File_content::bytes' method for operating of the raw content, which is
needed in situations where the data pointer is passed to a third-party
parser.

3778558608 os: reworked nitpicker_gfx/text_painter.h
This patch improves the `Text_painter` utility that is commonly used by
native Genode components to render text:

- Support for subpixel positioning
- Generic interface for accessing font data
- Basic UTF-8 support

Since the change decouples the font format from the 'Text_painter' and
changes the API to use the sub-pixel accurate 'Text_painter::Position'
type, all users of the utility require an adaptation.

b0b92e4ee2 vfs: pass root directory to plugins
This patch enables the use of the VFS from VFS plugins by passing a
reference of the root directory to the constructors of file-system
instances. Since it changes the signature of 'Vfs::Dir_file_system',
any code that uses the VFS directly requires an adaptation.

4bee38ea62 nic_router: DHCP server considers dns_server_from
The dns_server_from attribute of the dhcp-server tag has effect only if
the dns_server attribute of the same tag is not set. If this is the
case, the dns_server_from attribute states the domain from whose IP
config to take the DNS server address. This is useful, for instance, if
the stated domain receives the address of a local DNS server via DHCP.
Whenever the IP config of the stated domain becomes invalid, the DHCP
server switches to a mode where it drops all requests unanswered until
the IP config becomes valid again.

04c3ae56ed nic_router: read DHCP-server config only once
Until now, the DHCP server of a domain was re-constructed each time the
IP config changed. This is not necessary as a domain that acts as DHCP
server must have a static IP config as it would be senseless to act as
DHCP server and client at the same time. Now, a configured DHCP server
is constructed only when the Domain gets constructed and stays alive
until the domain gets destructed. Furthermore, we now throw Domain::Invalid
if there is no static IP config plus a DHCP server configured. However, by
now, this exception is not caught as it is not trivial to destruct the
domain at this point.

b344f2bc39 nic_router: fix pure virtual call in Interface
The Interface constructor previously tried to attach to a domain.  This
might include sending a DHCP request to get the domain a valid IP config.
But in order to achieve this, the constructor used a pure virtual method
of Interface which crashes due to the unfinished vtable. To fix this bug,
the attach attempt was moved to a new Interface::init method.

a3b04c55f3 nic_router_dyn_config.run: test re-configurability
A very basic test of the re-configurability. It overwrites the configuration
once without making any changes, once with removing all domains except
uplink, and a third time recovering to the initial configuration to see if
the clients keep going as soon as their domains are back.

92a30e0953 nic_router: handle configuration changes
The router reacts as follows to a configuration change:

1) Construct new internal configuration representation (the old one stays
   in place to be able to do comparisons in the following steps)
2) Iterate through all user-dependent objects (interfaces, link states, ARP
   information, DHCP information) and re-check which remain valid with the
   new configuration and which must be dismissed.
3) Adapt the objects that remain valid to the new configuration (re-write
   references) and remove or detach the dismissed objects.
4) Do a link state DOWN at each interface and a link state UP at each
   interface that remains attached to a domain.
5) Replace the old internal configuration representation with the new one

This way, the router keeps as much user dependent states as possible
while going through a configuration change. Thus, overwriting the old
configuration with an exact copy of itself is (almost) transparent to
clients of the router. Almost, because there are things the router must
do on every configuration handling, like re-scheduling the expiration
timeouts of links.
