`Object.prototype.__proto__` has been implemented by most JS
engines to give R/W access to prototype chains, well before it made
it into the standard. JerryScript has decided not to implement it,
exactly because it was not part of ES 5.1. The only fully
ES5.1-compatible way of accessing the prototype chain is
`Object.getPrototypeOf` for reading.
However, ES2015 defines `Object.setPrototypeOf` for rewriting the
prototype chain, and JerryScript has now an ES2015 subset profile.
So, this commit adds its implementation to JerryScript.
Note, this commit does _not_ add `Object.prototype.__proto__`,
since that is in the Annex B of ES2015 specification, which is
optional for non-web-browser hosts.

For negative out-of-range time values, ecma_date_year_from_time
fell into an infinite loop. (Moreover, for positive out-of-range
time values, it returned an incorrect year.) This patch fixes the
helper to return NaN in these cases (and ensures that its call
sites are prepared for NaN values).
Fixes#1657.

It is a workaround fix. The problem comes from the inaccuracy of the double rounding.

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.

For example Number(".") and Number("e5") should be NaN not
zero. Parsing Number("e") caused buffer overflow as well.
Infinity parsing is a bit faster now.
Fixes#1636.

Besides the breakpoint list the JavaScript source code is
also sent to the debugger. This feature allows debugging
eval() function calls.

The server can accept a string, execute it with eval,
and returns with the result converted to string. In
case of exception it returns with the exception message.

Add a notification for JerryScript API users that the jerry-api.h
will be removed in the future and should use the jerryscript.h
header instead.
Also update the examples in the docs and the targets where
the jerry-api.h is used.

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.

Triggering hashmap recreate during property delete may damage the

There are two types of NULL values in the property hashmap: deleted
entries, and never used entries. The current implementation tracks
only the never used entries, and never scales back the hashmap.
After this patch property delete can also recreate the hashmap, or
remove it entirely if there are too few items in the array.
