If module `arduino_serial_stdio` is used and `ARDUINO_UART_DEV` is `UART_UNDEF`, the STDIO is used for `Serial`. It requires that the used `stdio` backend implements `stdio_available`.
On ARM platforms, `__dso_handle` is used for dynamic shared objects. But it is also required if global static objects are used. To avoid that `sys/cpp11_compat` is required only for using the (re)defined `new`/`delete` operators, `__dso_handle` is moved to module `sys/cpp_new_delete`
The `new` and `delete` operators that don't need `libtsdc++` are also provided by module `sys/cpp_new_delete` for platforms that don't have the `libstdc++`. Since these operators in `sys/cpp11-compat` are just wrappers for standard `malloc`/`free` functions like in `sys/cpp_new_delete`, the `new`/`delete` operators that don't need `libstdc++` are used from `sys/cpp_new_delete`. Only the `new`/`delete` operators that require the `libstd++` are left in `sys/cpp11-compat`.
So it is sufficient for the use of the (re)defined `new`/`delete` operators that an application uses the module `sys/cpp_new_delete` instead of `sys/cpp11-compat` and thus also works on platforms without `libstdc++`.
This provides the same functionality as `static_assert()` provided by
C11 and has no advantages compared to it. Hence, encourage users to use
standard C functionality instead.
The vendor binary libraries of ESP-IDF are provided as a separate GIT repository. These libraries are defined as separate package for two reasons: 1. RIOT packages don't support to clone GIT repositories recursively; 2. ESP-IDF pulls a lot of other GIT repositories that are not needed when it is cloned recursively.

Some small changes to use a common document and naming style for all ESP SDK packages. The @defgroup command should start with the name to keep alphabetical order in doc as well as Kconfig
