Direct strings are a new type of direct ecma-values (no memory allocation
is needed for encoding them) in JerryScript. Currently magic strings,
external magic strings and uint values are encoded as direct strings.
The constant pool of JerryScript byte-code is changed to hold ecma-values
rather than cpointers to support direct strings.

It is a followup fix after #2169. It also fixes a memory leak.
This fixes#2198 and fixes#2204

Keys are `q` to quit, `w` to scroll up `s` to scroll down.

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

Aborts are similar to exceptions except they are not caught by catch
and finally blocks. Callbacks should honor aborts as well and return
them without processing them. Aborts are never thrown by JavaScript
code.
In the future certain events such as out-of-memory condition may
also throw aborts.

Compiled code blocks are sized in multiples of JMEM_ALIGNMENT,
but it's possible that some bytes at the end remain unused and get filled
with junk. This causes snapshot output to become nondeterministic.
To fix this, zero out the compiled code buffer before using it.

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.

Add C API to work with Array Buffers.
The following methods are added:

- jerry_create_arraybuffer
- jerry_arraybuffer_write
- jerry_arraybuffer_read
- jerry_get_arraybuffer_byte_length

Add new function to avoid code duplication.
Add two new test cases to jerry_exec_snapshot function:
* test enable copy byte-code with global mode
* test enable copy byte-code with eval mode

It wasn't properly checked if the given object was an arrow function, therefore it always got wrongly casted into `ecma_arrow_function_t`.

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.

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.

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.

Added two new api functions:
* jerry_parse_and_save_function_snapshot
* jerry_load_function_snapshot_at
The jerry_parse_and_save_function_snapshot function allows
creating snapshots from snapshot arguments and body source.
The jerry_load_function_snapshot_at function enables loading
back functions from a given snapshot as a JS function object.

This patch adds an extension to snapshots which allows storing
multiple position independent primary functions in a single
snapshot data. A new application called jerry-snapshot is
added to the project to manage snapshots. Currently the only
option is merging snapshots.

Before attempting to load a module, each provided resolver must be given an
opportunity to examine the name of the requested module without actually
loading it so as to canonicalize it, in case a module can be referred to by
multiple names.
Then, modules are loaded and cached by their canonical name.
