c629c54153 Make util/geometry.h C++20 friendly
- Move header to base/include to make it applicable for base types
  like 'Affinity' down the road.
- Represent 'Rect' as typle of point and area, which is the most
  common form of initialization, creates in valid 'Rect' by default.
- Turn Point, Area, and Rect into compound types, making x, y, w, h, at,
  area accessible without a method call
- 'Rect::Compound' function for constructing a 'Rect' from two points,
  replacing a former constructor
- Use result type 'Rect::Cut_remainder' instead of out parameters.

d19b751632 nano3d: remove surface-clear optimization
This patch fixes a GCC-10 compile error. Even though the optimization
was quite effective - I measured a speedup of factor 2 - it is not all
that important for the overall application performance. In the nano3d
case, we are talking about 1 vs. 2 percent of CPU time.

ffb931f8b1 nano3d: Fix header guard in sqrt.h
The code fails to build with clang due to the following warning/error:

  error: '_INCLUDE__NANO3D__SQRT_H_' is used as a header guard here,
  followed by #define of a different macro [-Werror,-Wheader-guard]

Fix this by removing the extra underscore from this header guard
definition.

ef741ef80d Change pixel format to 32 bits per pixel
Until now, Genode's framebuffer session interface was based on the
RGB565 pixel format. This patch changes the pixel format to 32-bit
XRGB where the X part is ignored. It adapts all graphical applications
and device drivers accordingly.

The patch also adjusts the users of the drivers_interactive packages,
assigning 64 MiB RAM and 1500 caps to the drivers subsystem, which is
sufficient for covering high resolutions at 32 bits per pixel and to
accommodate multi-component USB HID input stacks.

181c78d482 timeout: use uint64_t for all plain time values
This enforces the use of unsigned 64-bit values for time in the duration type,
the timeout framework, the timer session, the userland timer-drivers, and the
alarm framework on all platforms. The commit also adapts the code that uses
these tools accross all basic repositories (base, base-*, os. gems, libports,
ports, dde_*) to use unsigned 64-bit values for time as well as far as this
does not imply profound modifications.

cd3a5852d6 Warn about the use of deprecated headers
This commit enables compile-time warnings displayed whenever a deprecated
API header is included, and adjusts the existing #include directives
accordingly.

17c79a9e23 base: avoid use of deprecated base/printf.h
Besides adapting the components to the use of base/log.h, the patch
cleans up a few base headers, i.e., it removes unused includes from
root/component.h, specifically base/heap.h and
ram_session/ram_session.h. Hence, components that relied on the implicit
inclusion of those headers have to manually include those headers now.

While adjusting the log messages, I repeatedly stumbled over the problem
that printing char * arguments is ambiguous. It is unclear whether to
print the argument as pointer or null-terminated string. To overcome
this problem, the patch introduces a new type 'Cstring' that allows the
caller to express that the argument should be handled as null-terminated
string. As a nice side effect, with this type in place, the optional len
argument of the 'String' class could be removed. Instead of supplying a
pair of (char const *, size_t), the constructor accepts a 'Cstring'.
This, in turn, clears the way let the 'String' constructor use the new
output mechanism to assemble a string from multiple arguments (and
thereby getting rid of snprintf within Genode in the near future).

To enforce the explicit resolution of the char * ambiguity, the 'char *'
overload of the 'print' function is marked as deleted.

259b127f96 Polygon drawing and rudimentary 3D routines
This patch adds two new painters located at gems/include/polygon_gfx.
Both painters draw convex polygons with an arbirary number of points.
The shaded-polygon painter interpolates the color and alpha values
whereas the textured-polygon painter applies a texture to the polygon.
The painters are accompanied by simplistic 3D routines located at
gems/include/nano3d/ and a corresponding example (gems/run/nano3d.run).
