It is possible to change the default buffer size for log message creation via
environment variable:
export DLT_LOG_MSG_BUF_LEN=<value>
Instead of using a static buffer with size of 1390 bytes, the buffer is
allocated dynamically with the specified value.The max size is restricted to approx 65k.

So far, signal number had been output in signal handler.
However this was not so safety. And when syslog was used as log
output destination of dlt_log(), we could not see any info in the
same Life Cycle.
So dlt_log() is removed from signal handler and signal number is
newly output by DLT message and dlt_log() at exit.
This info will help analysis why dlt-daemon exits.

If application tries to send application registration request before
dlt-daemon startup, the request is sent twice as below:
1. Buffered request in user library buffer
2. New request when user app succeeds to attach to dlt-daemon
In previous, dlt-daemon had been output the registration messages
2 times even though these messages were come from same application.
This duplicated output is avoided by this change.
Warning message in case of dlt-runtime-context.cfg exists
is also avoided. This file is created when Control message: "Store Config"
is used. This is not irregular case.

This patch changes Context un-/registration message not to output DLT
by default for the purpose of reducing trace messages.
Actually dlt-daemon already sends almost same meaning control message
which can show Context un-/registration([get_log_info] and [unregister_context]).
These are duplicate message and should be suppressed in normal case.
Only if "Verbose = 1" is set in dlt.conf, the messages are output as same as before.

- When dlt_daemon_user_send_log_level() called in
dlt_daemon_process_user_message_register_context() fails -1 was returned
which caused dlt_daemon_process_user_messages() to stop processing
receiver buffer. Remaining data was stuck until new data arrived over
FIFO.
- Make debug output of dlt_daemon_user_send_log_level() more
verbose.

On context and application registration, the data needs to be read in 2
parts. If the first part was at the end of the receiver buffer, it was
wrongly removed whereas the complete data is not full received and
therefore interpretable. This has to be fixed by not removing the data
before everything is checked.
Thus, while readjusting the buffer to the first found header, the offset
was not properly updated.

Process User Messages: Fix buffer handling
In case application and context registration the buffer need to be read
two times. But before removing the data, the data need to be readjusted
to its origin. This was missing in a previous fix.
Furthermore, in case of corrupted description field, applications and
contexts will be registered anyway with the dummy description "Unknown".

ECU ID that is not default value
dlt-daemon overwrites ECU ID even if user log message already has the ECU ID that is not default value.
This phenomenon happens when application uses dlt_forward_msg().
Therefore, dlt-daemon is modified not to overwrite ECU ID if log message has already has the ECU ID.

MultiNode allows to connect DLT Daemons running on different operating systems,
e.g. in a virtualized environment. The central component is the Gateway DLT
Daemon which connects external DLT Clients, like the DLT Viewer running on a
host computer, with Passive DLT Daemons running on nodes without a physical
connection to external DLT clients. The Gateway DLT Daemon itself acts as a
DLT client when connecting to a Passive DLT Daemon.
To use the Gateway functionality, it has to be enabled in dlt.conf:
GatewayMode = 1
All communication between passive nodes and DLT Viewer has to be send via the
Gateway node. The Gateway node forwards log messages coming from passive nodes
to all connected DLT clients. It also forwards command and control requests
coming from DLT clients to the corresponding passive node.
The Gateway DLT Daemon read a configuration file (dlt_gateway.conf) at startup
with information about Passive DLT Daemon connections. Afterwards, the
Daemon will try to connect to the passive DLT Daemons. If the connection cannot
be established after the configured timeout, the Gateway DLT Daemon will give up
connecting.
The configuration file has to contain the following information about a passive
node:
[PassiveNode1]
IPaddress = 192.168.2.35
Port = 3490
EcuID = ECU2
Connect = OnStartup
; timeout in seconds
Timeout = 10
Precondition is, that the passive node is configured with the correct ECU id,
ECU2 in this case. If the passive node sends messages with another than
configured ECU id, the Gateway DLT Daemon will shut down the connection.
It is also possible to connect to a passive DLT daemon using the
dlt-passive-node-ctrl application. In this case "Connect=OnDemand" has to be
configured in the configuration file.
To connect to PassiveNode1, "dlt-passive-node-ctrl -n ECU2 -c 1" has to be
executed.
With "dlt-passive-node-ctrl -s" the status of passive node connections can be
retrieved.

When using DltLogstorage on internal storage device, it is needed to
reduce writing to internal storage device as much as possible.
This patch introduces sync strategies to Logstorage to provide that
functionality.
The ON_MSG strategy is the default sync strategy that flushes every
written log message to the storage device (fflush).
The ON_DAEMON_EXIT strategy only flushes data to disk when the daemon
exits.
The strategy can be defined per filter in the dlt_logstorage.conf
configuration file by adding
SyncBehavior=<Strategy> to a configuration.

Control applications running in the same Linux OS should be able to communicate
with the DLT Daemon via a socket connection.
To be able to do that, the DLT Client library need to be extended. DLT
Clients connected via this UNIX socket are not handled as normal DLT
Clients and no log messages will be forwarded to them. This avoids
problems in situations when a control application is connected to the
DLT Daemon before any other 'real' DLT Client (e.g. DLT Viewer) is
connected. In this situations, all already stored log messages are
flushed to the control application and therefore lost, because the
control application most likely ignore all incoming messages besides the
one in which it is interested in.

The event handling has been reworked in order to use epoll and
restructure the code.
There are 2 new structures.
The DltConnection which contains all basic connection information, like
the type, the file descriptor, and the receiver structure corresponding.
The DltEventHandler that manages the DltConnections and the associated
events.
The concept is basically the following. The daemon will create different
connections, serial connections, socket connections, fifos etc ... Each of
them will then register itself to the event handler, and give it the
ownership of this connection. From this point in time, the daemon can act
on the connections.
Once an event is triggered, the event handler will call the connection
specific callback, creates new connections when clients arrives,
and potentially destroy the connection in case of hangup.
On exit, the daemon cleanup the event handler, which leads to the
destruction of the connections.
The work there is a first step for a global restructuring. Several
modification will follow, in order to rationalize the different daemon
structures, and avoid variable and code duplication.

When logging-mode of the DLT-daemon was set to DLT_USER_MODE_INTERNAL or DLT_USER_MODE_OFF and a client tried to connect to the daemon,
the socket for accepting new connections would be closed. This would make connecting to the daemon impossible, even if the logging mode
was reset to DLT_USER_MODE_EXTERNAL or DLT_USER_MODE_BOTH.
Fixed this by removing conditional check on the logging mode - clients connections are always accepted now. If the logging-mode is
being switched from INTERNAL to EXTERNAL or BOTH while a client is connected, the client will then start to receive messages normally.

- Make dlt-daemon configurable to specify directory of fifos and port of dlt-daemon, this
allows to run multiple instances of dlt-daemon at one node at the same time. This is useful
in testing environment where simultanous tests should not interfere due to the same
instance of dlt-daemon
- dlt-daemon: add option -t <dir> to specify a directory where all fifos will be created
- dlt-daemon: add option -p <port> to specify the port under which dlt-daemon can be connected
- client-library: add environment variable DLT_PIPE_DIR to specify a non-default directory
of fifos for logging applications
- client-library: add environment variable DLT_DAEMON_TCP_PORT to specify the port under which
dlt-daemon can be reached (especially when using dlt-receive)
