This patch closes#2170.

The pre-scanner now is able to track all variable declarations and produces a compressed
stream which store this data for each function and catch block. When a function or
catch block is parsed, this information is decoded and the appropriate variables are
created. Furthermore a stack scope is created which contains the currently available
local variables and their register or literal index.

Currently it evaluates the given expression in the context of the top most stack frame.
The expression should access to any variables and arguments that are in the scope chain.
Implement the eval_at request with the level of the scope chain as a further argument.

Return with the object`s toString() method instead of create a json formated string from it.
It could have led to an error in previous cases (an object contains itself etc.)

It supports to list the scope chain of the current execution context and see
which variables are available.

- Properly display data during parse
Furthermore hide global functions of the debugger.

Replace DisplayData to DebuggerAction. The new class has only four type
options. Furthermore several functions returning with DisplayData is
changed to return with string.

With this feature the use can restart the actual debug session
(similar to the multiple source context reset) within a client.

In some cases the debugger catches (reports) the same
exception multiple times. This is confusing since these
not new errors. This patch fixes this behaviour.

Aborts are not caught by catch/finally blocks,
so it is possible to stop a script using the debugger.

Before this patch the JS execution is started right after the parsing
is completed. The problem is that some parts of the JS code is executed
before the debugger had any chance to insert pending breakpoints due
to network latency. This patch adds a delay after parsing when at least
one pendding breakpoint is available.

Whit this enhancement the debugger can able handle more than one source file across the new source wait mode.
This feature can be used by the python client with the --client-source [paths] switch.
The client will store every source path, when the debugger send a signal about the waiting status, then the client will send one file from the list.

With this feature the debugger webIDE and the python client can able to send a source code to the debugger while that is running in wait mode.
This feature can be activated with the --debugger-wait-source switch and the debugger will wait for the source messages.
If every message part are received the debugger will continue the exectuion with the initalized options.

Convert debug server port from a compile-time constant to a context
variable. This enables each engine instance (either running in the
same process or in different processes) to listen for connections
at different ports, i.e., multiple engines can be debugged at the
same time on the same machine.

Reworked source(src) command to display a given range of the code, defaults to 3.
Added display command which does the same as the source, except it displays the source code everytime a breakpoint is hit.
Made tests for display, extended tests for src.

Now the debugger generates a breakpoint for each function before
its first executable statement. This allows inspecting the function
arguments. Position (line and column) info is also added which
simplifies finding of anonymus functions. Several tests were
update to check more corner cases.

The debugger supports setting breakpoints, execution control (step, next, continue)
and getting backtrace. The communication is WebSocket-based, so a browser can
communicate with JerryScript without any intermediate application.
