By incorporating the sculpt version into the path where customizations
are stored, we can update and roll back sculpt versions without risking
configuration incompatibilities. By default, the sculpt version
corresponds to <genode-dir>/VERSION.
The condition must first check the io-buffer length and then check the
content. Otherwise, cat'ting a file that is padded with zeros up to
page size (io-buffer size) yields an out-of-range read access.
This patch replaces the terminal's formerly built-in fonts with the new
VFS-based font handling.
To avoid the copying of the terminal's font configuration across run
scripts, this patch adds the new terminal/pkg runtime package, which
includes everything needed for instantiating a terminal: the actual
terminal component, the library dependencies (vfs_ttf, which in turn
depends on the libc), a font (bitstream-vera), and a reasonable default
configuration.

The 'stat' method is called for all paths, not just the specific file
system node of the ROM module. The ROM update is needed only in the
latter case.
Otherwise, when always updating the ROM on stat, stat calls on the VFS
become very expensive in the presence of a mounted ROM module if the ROM
is obtained from fs_rom (which re-watches the file and all its
individual path elements whenever the 'update' RPC function is called).
This patch make the scenario independent from device drivers, which were
solely needed to display a graphical terminal. The output of the
scenario is now printed via the log_terminal component, which makes the
logging output of nightly tests more useful.
The pattern rule picked up the wrong platform_services.cc in the
depot-archive case only because the archive integrates generic and
sel4-specific source files into REP_DIR.
The Ada runtime can now be set with the ADA_RTS variable. The ada
library builds a (currently) minimal runtime from the gcc sources that
come with Genode (to stay consistent with the used compiler) and sets
the runtime path accordingly. It is build as a shared library ada.lib.so
which needs to be added to the build files.
I split the existing Ada test into program and library, and moved it
to libports as it depends on the runtime library residing in this
repository too.
Fixes#2748
VFS plugin to replicate from one file-system to another. Can be used to
seed a mutable file-system with an immutable file-system. The plugin is
configure with two paths, a read-only path, and a read-write path. This
is an initial implementation that copies files on open. It is not
optimized to perform actual copy-on-write, but the result is the same.
<vfs>
<dir name="immutable"> ... </dir>
<dir name="mutable"> ... </dir>
<dir name="cow">
<cow ro="/immutable" rw="/mutable"/>
</dir>
</vfs>
Fix#2745
Reduce the size and forward compatibility of VFS file-system
constructors by passing an object holding accessors for 'Genode::Env',
'Genode::Allocator', response handlers, and the root file-system.

When working with GPIO interrupts on i.MX6SX for Ethernet PHYs
it became obvious that the GPIO driver repeatedly receives interrupts
for the same event, because it acknowledges the interrupt before a
client has handled the event.

In other words: Loosen the former property that suspend can only be
called from the first user stack and, thus, enable additional user
stacks, e.g., in coroutine libraries.
Fix#2737
This driver component provides support for using consumer NVMe storage
devices, i.e. it omits name space managment and will always use the
first name space, on Genode. For now it defaults to a reasonable low
configuration:
- 1 I/O queue (completion/submission tuple)
- 128 entries in the I/O queue
- 4096 as the only I/O transaction memory page size
Fixes#2747.
The 'default' attribute is useful to change the default value for those
protocol attributes that are not explicitely set in the configuration of
the component.
