This patch fixes#2230 and fixes#2237.
Test cases are added for both issues and also adds new cases which caused the same error.

The length*sizeof(ecma_value_t) may overflow on 32 bit systems which
cause a memory corruption when the values are filled.
Fixes#2182.

It wasn't properly checked if the given object was an arrow function, therefore it always got wrongly casted into `ecma_arrow_function_t`.
Fixes issue #2110
*plus fixing a typo in the comments

Freezing the global object and later trying to add properties to it caused an assertion error (issue #2105).
This patch fixes the issue.

This patch fixes#2106. The problem was that the function always tried to transform the array-like object to TypedArray object even if there was an error during TypedArray creation.

This patch fixes#2108. The problem was if the convertible number had less significant fractions digits than the requested, the result was filled with memory junk instead of zeros.

Fixes issue #2094, which introduced an error caused by jerry_value_is_syntax_error.
The problem was that the function used strcmp instead of strncmp while checking if err_str_buf contains syntax error and it caused buffer overflow.

This patch fixes this bug which caused corrupted stack by preventing unnecessary double to ascii conversion even if
the convertible number of digits is higher than allowed.
In addition, improved ecma_double_to_binary_floating_point function by removing a needless buffer.

Fixes issue #2073, which introduced an error caused by Date.parse()
The problem was that the function didn't properly check if there was a ':' after the hours.
If any UTF8 character was inserted there which got decoded into multiple characters, it caused the pointer to point at a wrong character.

Fixed an unhandled corner case while parsing slashes and template literals.
This patch fixes#2039 and adds a test case for it.

The issue was reported against v1.0 and isn't reproducible anymore.
Still, adding the then-faulty input to the regression test suite to
prevent it occuring again.

This patch extends the infinity and zero parsing of the convertible number by checking the normalized number exponent part.
This improvement prevents the engine's hanging while converting extreme big numbers.

Note: the special this behaviour of arrow functions is not implemented.

Issue #1990 revealed an unhandled corner case while parsing pattern. This patch fixes it and also adds a test case.

If a literal was assigned the unused flag it wasn't freed, however it could have been not empty, therefore should've been freed.

The radix conversion code path was very messy which made it hard to understand
what was happening inside of it. The code got cleaned up, and a lot of comments
were added that explain what is happening and why.

Functions has several built-in non-enumerable properties, and
they are correctly ignored during enumeration after this patch.
External function prototype is also lazy enumerated.

So far a freed variable was tested during error flag inspection.
This patch fixes it and #1972 as well.

The buffer size was previously badly computed since scale == 0 case was not checked, therefore the buffer size was smaller than intended.
This patch fixes this issue.

Fixes#1367.
From now numbers are represented as binary floating-point which guarantees the expected operation of toFixed function.
