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.

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.

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.

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.

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.
