Overflows in conversions from floating-point to integer are
undefined behavior in the C99 standard. (Clause 6.3.1.4: "If the
value of the integral part cannot be represented by the integer
type, the behavior is undefined.")
When UBSAN is enabled, this gets reported at `srand()` calls. (The
random seed is usually initialized using the date port API, which
represents dates as `double`s. But `srand` takes an `unsigned int`.
A simple cast from `double` to `unsigned` becomes undefined
behavior if the value is too large. And "now" is too large
nowadays. So, effectively, all executions start with an undefined
behavior.)
This patch fixes this by casting the floating-point value of the
date to an integer through a union.

MSVC doesn't support C99 VLA (variable-length array).
Use fixed size arrays in API examples and use JERRY_VLA macro
in unit tests to make these tests buildable on Windows too.

Their length (size) is known at compile time. Therefore `sizeof`
is more efficient for them.

Issue #2053 has highlighted the fact that random numbers are always generated with the same seed.
An example of generating different random numbers, other than the original seed, has been added to the documentation.
Furthermore srand initialization has been added to jerry-main, and targets.
Update test-common.h with srand call.

Markdown files in the docs/ directory can now be annotated to turn
fenced C code blocks into unit tests. The recognized syntax is:
[doctest]: # (name="test.c", test="run")
```c
// unit test code
```
The commit also fixes the issues revealed during the initial
annotation.

The built-in `print` is removed from jerry-core, but an external
`print` implementation is added to jerry-main. From now on, all
embedders of the engine have to implement their own `print` if they
need such a functionality.
For printing results in REPL mode of jerry-main, the external
`print` handler is called directly instead of looking up the `print`
function registered into the global object. (The two are the same,
but the indirection is not needed anymore.)
Because jerry-core does not contain `print` anymore,
`jerry_port_console` is removed from the port API. The default port
is updated, i.e., the implementation of `jerry_port_console` is
removed. Additionally, all references to `jerry_port_console` in
jerry-main are replaced by `printf`.
Speculatively, `jerry_port_console` is also removed from all
non-default targets. Most targets implemented it for the sake of the
engine only; in those targets the removal was trivial. Where the
function was called from the embedder application as well, the
calls were replaced with equivalents (e.g., `printf`, `printk`).
NOTE 1: This is a breaking change!
NOTE 2: This patch still leaves several targets without a JS `print`
implementation.

All public headers should follow the pattern `jerryscript[-*].h`.
The `jerry-api.h` to `jerryscript.h` renaming has already happened
a while ago, now it's time for the port API header to follow.
This patch
* renames the public header file,
* updates all includes to use the new file name (in `jerry-main`,
in all the targets, and in the docs), and
* keeps `jerry-port.h` as a deprecated forwarding header to leave
some time for external users to follow up with this change.
As a related change, the header of the default port implementation
is also changed to `jerryscript-port-default.h`.

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.
