9bc42ecd87 ports: native version of DosBox
DosBox is DOS-Emulator which is mainly used for playing old
DOS games on POSIX systems and newer Windows versions.

This port of DosBox runs natively on Genode by using its
SDL backend. It is currently only works on x86_*.

Fixes #937.

1ed4b9fef9 Use log_terminal in noux.run script
This patch changes the noux.run script to use the new log_terminal
component instead of an UART driver. Besides being a nice way to test
the log_terminal service, the new version is much simpler and it just
became compatible to Linux as it no longer relies on an UART driver.

1953acae77 qt4: Workarounds for missing C++11 compatibility
Since we switched to using C++11 by default, the webkit-related

8b8e3ef7a5 noux: calculate inode value from path
There are programms that use struct stat's st_ino field to check certain
conditions. Since we are using multiple filesystems in a noux session we
cannot use the inode number which the actual filesystem provides.
Therefore we calculate a random inode number by hashing the stated path.

Fixes #299.

7ac23a2419 libports: use Timer_session as SDL's timer backend
A timer session is now used instead of a jiffy counter. This way, libSDL
can use a time source that is not bound to the granularity our libc's
nanosleep implementation. Currently, the granularity of nanosleep is in
the order of 10 milliseconds, which is far to coarse for the use of
SDL-using applications such as DosBox.

fde93c3284 init: don't call Rom_session::dataspace() twice
In general, requesting a dataspace from a server twice is no good
idea. The server might react in a unrecoverable fashion. E.g. the rom_fs
service always throws away the corresponding dataspace from the first call
of dataspace(), and constructs a new one.

27aeecf5d1 cli_monitor: add a 'gdb' command
This patch adds a 'gdb' command to 'cli_monitor', which makes it possible
to debug an application with GDB.

The command works similarly to the 'start' command, but instead of
starting the subsystem binary directly, an 'init' subsystem gets
started, which then starts 'terminal_crosslink', 'noux', GDB and
'gdb_monitor' (which starts the application binary as its target).

So, for the 'gdb' command to work, these additional components need to
be available, too. 'terminal_crosslink', 'noux', 'gdb_monitor' and the
file 'gdb_command_config' are expected to be ROM modules. The Noux GDB
client needs to get mounted at '/bin' in Noux and the target binaries need
to be available as ROM modules (loaded by 'gdb_monitor') and also mounted
at '/gdb' in Noux (loaded by the GDB client).
Additionally, the source code of the target application can be provided
at '/gdb/src/ in Noux. How the Noux mountings get established can
be configured in the 'gdb_command_config' file. The default configuration
in 'os/src/server/cli_monitor/gdb_command_config' mounts GDB from a tar
archive named 'gdb.tar', the GDB target binaries from a tar archive named
'gdb_target.tar' and the target source code from a tar archive named
'gdb_target-src.tar'.

The patch includes an 'expect' include file (ports/run/noux_gdb.inc)
which provides functions that help to create those tar files:

- 'create_gdb_tar' creates a tar archive for the 'gdb' client
- 'create_binary_tar' creates a tar archive for the target application
- 'create_source_tar' creates a tar archive for the source code of
  the target application
- 'create_binary_and_source_tars' is a convenience wrapper for the previous
  two functions

The patch also includes an example run script
(ports/run/noux_gdb_dynamic.run).

The 'gdb' command supports the following command line options:

- --ram: the initial RAM quota provided to the whole subsystem
         (including the GDB-related components)
- --ram-limit: limit for expanding RAM quota
- --gdb-ram-preserve: the RAM quota that 'gdb_monitor' ahould preserve
                      for itself

Fixes #928.

2329184ddb cli_monitor: make preservation limit a hard limit

e0be6b9ed6 cli_monitor: ensure blocked children are waked up
When a command was executed, it is necessary to check not only whether the
preservation limit of the ram quota is reached, but also whether new ram quota
is available (e.g.: consequence of the kill command), and children are waiting
for additional resources.

59d6157441 l4lx: ballooning by using new parent interface
Implement a ballooning mechanism in L4Linux similar to solutions like XEN's
balloon driver. Therefore the new parent interface extensions for requesting
and yielding resources are used. L4Linux registers a yield signal context at
its parent. Whenever the parent triggers a yield, the balloon driver blows up,
which means it requests all pages available, and then frees the corresponding
backend memory.

f82e1a7092 nitpicker: Late allocation of virtual framebuffer
This patch changes the interface of Nitpicker to support dynamically
dimensioned virtual frame buffers. This solves two problems:

First, it enables a client to create a connection to nitpicker without
donating much session quota in advance. The old interface required each
screen-size-dependent client to donate as much memory as needed to
allocate a screen-sized virtual framebuffer. For clients that are
interested int the screen size but cover just a small portion of the
screen (e.g., a banner, a menu, an applet that sits in the screen
corner), this overprovisioning is painful. The new interface allows such
clients to upgrade the session quota for an existing session as needed.

Second, because each nitpicker session used to have a virtual frame
buffer with a fixed size over the lifetime of the session, a client that
wanted to implement a variable-sized window had to either vastly
overprovide resources (by opening a session as large as the screen just
in order to be prepared for the worst case of a maximized window), or it
had to replace the session by a new one (thereby discarding the stacking
order of the old views) each time the window changes its dimensions. The
new interface accommodates such clients much better.

047d851fb6 Noux: add basic 'Ctrl-C' support
This patch implements the POSIX signal functionality needed to interrupt a
running Noux GDB by pressing 'Ctrl-C'.

It allows to register a signal handler for the 'SIGINT' signal, which
gets executed after 'Ctrl-C' is received from the terminal. With the
current state of the implementation, the signal handler only gets executed
when the Noux application calls a 'read()', 'write()', 'ftruncate()' or
'select()' syscall.
