This extension provides the following facilities:
- registering modules,
- module resolvers, and
- an API for retrieving a module instance given its name.
A module is defined as a global static structure containing a pointer
to a string which is the name of the module, and a pointer to a function
which will be called when an instance of the module is needed.
A module resolver is a function that accepts a string holding the name
of the module and returns a `jerry_value_t` in an out-parameter and
`true` if the module was found, or `false` if it was not. If it returns
`true` and the out-parameter has the error flag set then the API will
pass it through without caching.
This extension provides a built-in module resolver which attempts to
load modules that follow the above module definition.
The API provided by this extension invokes all module resolvers it
receives in sequence to attempt to resolve the name of a single module.
After one resolver returns `true` and a `jerry_value_t` that represents
the module the API stops iterating over the remaining resolvers and
caches the value if its error flag is not set. It then returns the
`jerry_value_t`. The API will return a `jerry_value_t` containing an
error indicating that the module was not found if it reaches the end of
the list of resolvers. The error it returns has an extra property
`"moduleName"` the value of which is a string containing the name of the
module that the API was asked to resolve.

tizenrt-arttik05x treats warning as error for uninitialized use.
This patch fixes the error in jerry-ext/arg by initializing to zero.

Add a function in jerryx/arg.
jerryx_arg_transform_object_properties, it will validate the properties of a JS object, and convert those properties into native type.

Added `handler` module to `jerry-ext` to contain implementation of
commonly used external function handlers: `assert`, `gc`, and
`print`.
Also adapted jerry-main to use jerry-ext/handler

It provides some APIs for binding developers, so that
they can validate the type of the js argument and convert/assign them
to the native argument.
