The screenshot trigger displays a little red dot at the upper-left
corner of the screen. When touched or clicked-on, it generates an
artificial key-press-release sequence for the print key and disappears
for one second. In this time, a separate screenshot component can handle
the print key by capturing the screen without the red dot appearing in
the saved picture.
The 'file' library makes the gems API depend on the libc, which is not
desireable because most users of the gems API have no direct libc
dependency.
With the changes of issue #4599, the build of each src archive that
depends on the gems API would attempt to build the 'file' library and
thereby demand the libc.
Note that the 'file' library is a relic that should better not be
promoted as part of the gems API. Hence, this patch removes the file
library from the gems API and adds it to the src archives of the few
remaining users.
Issue #4599
By using the new functions provided by the base API, this patch removes
the dependency of several components from include/decorator/xml_utils.h.
Issue #4584
* retrieve Genode::Env from plugin, this way no mesa applications need to
be changed.
* add 'vfs_gpu' api
* remove when all required functionality is implemented within the plugin.
issue #4380
When a <gpu> node is present in the VFS, the plugin opens a
Gpu::Connection for each open call to the 'gpu' node and installs a
completion signal handler. A read only to the fd returned only comes
back if a completion signal has been received between two read
transctions to the fd.
For now the Gpu::Connections can be retrieved by calling the
'vfs_gpu_connection(unsigned long id)' function. The id can be obtained
using 'stat' on the 'gpu' device and is located in the inode (st_ino)
field of the stat buffer.

Warning!
The current version of the file vault is not thought for productive use but
for mere demonstrational purpose! Please refrain from storing sensitive data
with it!
The File Vault component implements a graphical frontend for setting up and
controlling encrypted virtual file systems using the Consistent Block Encrypter
(CBE) for encryption and snapshot management. For more details see
'repos/gems/src/app/file_vault/README'.
Fixes#4032
Both, trace_logger and vfs_trace had their own trace_buffer.h. This
commit consolidates the existing implementations and provides the
resulting trace_buffer.h at 'include/trace/'. It thereby becomes part of
the trace api archive.

* the GPU multiplexer now offers the platform service to the Intel
framebuffer driver (driver_manager)
* ajdusted drivers_managed-pc to hand out resources to the GPU driver
* adjust quotas
