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.

WARNING: BREAKS CONFIG COMPATIBILITY!
This commit changes the configuration interface of the NIC router in a way that
may break systems that use the component without proper adjustment!
How to adjust:
At each occurrence of the 'dns_server_from' attribute in a NIC router
configuration replace the attribute name with 'dns_config_from'. The attribute
value remains unaltered.
DETAILED DESCRIPTION
The new attribute name 'dns_config_from' reflects that also other aspects of
the DNS configuration of the denominated domain are used by the DHCP server
that holds the attribute. This commit is a preparation for forwarding also the
domain name (DHCP option 15) with the mechanism behind the attribute.

File size must be the same as the number of bytes that can be read from
the file. Otherwise, this will trigger a `Truncated_during_read`
exception.

issue #4233
Adapts Dir_file_system::open_composite_dirs in a way that it returns "success"
when the leaf node of the path is an empty directory but "lookup failed", as
usual, if one of the other directories on the way to the leaf node is empty.
I couldn't find a technical reason why we used to return "lookup failed" when
only the leaf node was empty.
The commit also adds a test for en empty root directory and empty
sub-directories to the fs_query run script.
Fixes#4198
The fs_query component used to exit with an uncaught exception if a queried
directory didn't exist. Now, fs_query will catch this event and simply skip the
affected query, thereby indicating to the user the inexistence of the
queried directory.
Ref #4032
If no window has ever been focused, next() always returns an invalid
window id. As a consequence, there is no way to cycle through the focus
history without an explicit focus event (e.g. mouse hover).
Instead, next() should return the first window from the focus history if the
currently focused window is not present.

Adds the <new-file> operation to the fs_tool. When configured, the
<new-file path="...">...</new-file> tag will cause creation or overwriting of
the file given through the 'path' attribute. The file will contain the text
content of the tag.
Ref #4032
This patch moves the utility from the app/text_area to os/vfs.h to make
it easier to use by other components. By hosting the 'New_file' as a
friend alongside the 'Directory', we can now pass a 'Directory' as
constructor argument, which is consistent with other utilities such as
'File_content'.
As a further improvement, the new version supports the implicit creation
of the directory hierarchy leading to the new file.
Issue #4032
By adding an attribute 'size="yes"' to a query, one instructs fs_query to
report also the size of each queried file as attribute 'size' of the
corresponding 'file' node.
Ref #4032
The fs_query component used to try watching all files it found resulting in
errors on files that are not watchable. For some files, however, the watch-
feature doesn't make sense as they are not readable (no content, no size).
Now, fs_query will check first whether a file is readable and skip watching
if it isn't.
Ref #4032
When configuring fs_query to print the content of files it used to try so for
all files it found resulting in errors on files that are not readable. Now,
fs_query will check first whether a file is readable and skip printing the
content of those that are not.

Managing ssh event file descriptors was performed from two different
threads which could cause reallocation of structure used in other thread
in a call to 'poll' function.
Splitted initialization to parts and moved ssh event part into ssh loop.
Issue #4095
Moved creating ssh loop thread after initialization of wake up server
file descriptors to make sure that they will be properly handled even in
first loop run.

The default size is on most kernels 512M. On OKL4 we have to use 800M,
because of the statically configured memory ranges in the OKL4 kernel.
By avoiding a specific amount of memory, the default Qemu memory sizes are
used.

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.
Fixes#4140
pthread.0 acquires a write buffer mutex and calls potentially
blocking fs operations. The EP thread handles session requests and tries to
acquire the same write buffer lock. IO progress events for pthread.0 are
handled by the EP thread, which however is blocking on the write buffer mutex.
The commit uses two write buffers, one which is filled by the EP and a second
which is used by pthread.0. The two buffers are swapped protected by a mutex
without invoking blocking fs operations.
Issue #4095
The exec_terminal generates a config report which is used as input ROM for
sandbox/init, which does not support an "<empty>" node.
An empty config node is empty, without an node.
