Instead of using the user passphrase directly, use its SHA256 hash calculated
using libcrypto. The passphrase hash is still stored in the key file to be
used as base for the very primitive way of generating the private key.

Closing the keyfile handle after a write operation wasn't synchronised to the
actual end of the write operation.
Issuing a write operation at the back end returns successfull as soon as the
back end has acknowledged that it will execute the operation. However, the
actual writing of the data might still be in progress at this point. But the
plugin used to close the file handle and declare the operation finished at this
point which led to warnings about acks on unknown file handles and leaking
resources. Now, the plugin issues a sync operation directly after the write
operation and waits for the sync to complete. This ensures that the plugin
doesn't declare the operation finished too early.
Ref #4032
The unlocking operation in the trust anchor was broken wich caused bad keys in
the CBE. This rewrites the whole operation to work as desired. Note that this
doesn't make it more safe! The private key is still almost the same as the
passphrase and stored plaintext.
Ref #4032
The plugin used to close file handles via the 'vfs_env.root_dir.close'.
However, this lead to resource leaks and apparently isn't the right way to
do it. Other VFS plugins do it by calling 'close' directly on the handle and
doing it in the trust anchor plugin also, fixes the leaks.

There were no means for issuing a Deinitialize request at the CBE using the
CBE VFS plugin. The new control/deinitialize file fixes this. When writing
"true" to the file, a Deinitialize request is submitted at the CBE. When
reading the file, the state of the operation is returned as a string of the
format "[current_state] last-result: [last_result]" where [current_state] can
be "idle" or "in-progress" and [last_result] can be "none", "success", or
"failed".
Ref #4032
When discarding a snapshot, the CBE VFS plugin didn't communicate the ID of
the snapshot to the CBE. Instead it set the ID argument to 0. Therefore the
operation never had any effect.
Ref #4032
The snapshots file system used to return the number of snapshots on
'num_dirent' when called for the root directory although it was expected to
return 1. This confused the tooling ontop of the VFS.
Ref #4032
Despite being readable, the files control/extend and control/rekey proclaimed
that they were not when asked. This caused the fs_query tool to not report the
content of the files although it could have.
Ref #4032
Stat calls on the control/extend and control/rekey files returned a bogus file
size that led to an error in the VFS File_content tool. The tool complained
that the size of the file determined while reading the content differs from the
one reported by the stat operation. Now, the stat call will always determine
the actual size of what would be read. However, it isn't guaranteed that this
size doesn't change in the time after the stat operation and before the read
operation.

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.

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.
Issue #4095
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.

The exec_terminal generates a config report which is used as input ROM for
