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.

By using constructors/destructors we unify the case of static linking with
that of dynamic linking, and we reuse the build flag FEATURE_INIT_FINI. Using
constructors/destructors also allows us to cover the case where library
constructor/destructor functionality is unavailable, because we can expose the
module registration/unregistration functions as global symbols, to be called
explicitly from within the application.

This unreported test issue revealed an assertion in jmem_heap_finalize ().
During the conversion the lot of additional information what a cesu8 represented string needs caused overflow while setting the new ecma_string_t variable's length. This patch fixes this issue and the mentioned test case is available here:

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.

Currently new ArrayBuffer(length) does not conform to ES2017.
Major JS implementations follow ES2017 for ArrayBuffer(length).
For example, new ArrayBuffer(length) should not throw RangeError
for length = NaN, undefined, negative number, floating point, and so on.

The resolvers argument that is passed to jerryx_module_resolve() is
not mutated by the function. Therefore the argument should be const.
In the docs, a static const array is passed, but this currently does not
work w/o a cast. This patch fixes this.
