data: Double quote formatted date-times.
JSON does not support time values, thus, we need to treat this is a string.

data: Format binary bytes as \xXX rather than \XX.
data: Improve serialization of binary data.
Instead of calling strbuf_append() for each byte, precompute the string in a
simple for-loop and then append the result to the buffer. This basically
inlines a formatter specific to this use-case and, thus, should be must
faster.

frontend: Don't send debug logs to the client (for now).
Later, this should be configurable by the client at runtime.

frontend: Send connection-related log messages to the client.
This is done by registering a logging callback which will send all messages
originating from a thread currently handling a connection to the respective
client. For this, the connection object is stored in a thread-specific data
segment.

sysdb: Handle EOF from the server.
client: Correctly handle EOF in sdb_client_connect().
client: Added an EOF flag to the client object.
In a lot of cases, a client is passed through a couple of functions in order
to handle I/O. Adding the flag will make it easier to access the information
in the right location without having to worry about 0 return codes (which mean
different things in some cases anyway, e.g. in sdb_client_recv() which returns
zero if an empty message (header only) has been received).

sysdb: Use the asynchronous readline interface; handle asynch server replies.
For this, setup the terminal in non-canonical, raw mode in order to be able to
handle each single character input. This allows to handle user input and
asynchronous server replies at the same time but without the need to give up
sequential operation (no threads are required for the asynchronous operation).
Instead, select() is used to do the input multiplexing allowing to easily
handle different output.

An attribute value is now stored as sdb_data_t, supporting all data-types
which are supported by that type.
JSON-serialization does not fully support that yet, though.

sysdb: Implemented input scanner and simple command handling.
Reused the frontend parser lexer to identify single queries (terminated by
semicolon). No other parsing of the command is done by the client to make the
frontend the ultimate truth in regard to the parser (including simple stuff
like comments).
The query is then sent to the daemon and the reply will be printed to the
standard output channel.

When greater than (or equal to) zero, this parameter let's the parser parse a
substring of the specified query. This makes it easier to pass in a command

We don't have any concept of service inheritance (yet?).

Fixed some issues identified by static code analysis.
The following issues were identified and fixed:
* Allocator sizeof operand mismatch in dbi utils.
* Dead increment in tools/sysdb/input.
* Memory leak (and leaving behind invalid memory) in tools/sysdbd/configfile.
* Out-of-bound array access in core/plugin (the original report by the clang
analyzer was wrong but pointed to a location affected by a related
problem).
* Stack address stored into global variable in liboconfig.
Thanks to cppcheck and the clang analyzer!

sysdb: Use the flex scanner generator for reading input.
The idea is to implement a minimalistic parser which understands all valid
input and which is used to determine if an input line is part of an existing
command or a command on its own. This information will then be used to update
the prompt (and possibly to determine other information as well).
The scanner's YY_INPUT "method" is overwritten in order to use readline and
custom buffering for user input.
