OpenCores Ethernet MAC has a relatively simple interface, and is
already supported in QEMU. This makes it a good candidate for enabling
network support when running IDF apps in QEMU, compared to the
relatively more complex task of writing a QEMU model of ESP32 EMAC.
This driver is written with QEMU in mind: it does not implement or
handle things that aren't implemented or handled in the QEMU model:
error flags, error interrupts. The transmit part of the driver also
assumes that the TX operation is done immediately when the TX
descriptor is written (which is the case with QEMU), hence waiting for
the TX operation to complete is not necessary.
For simplicity, the driver assumes that the peripheral register
occupy the same memory range as the ESP32 EMAC registers, and the
same interrupt source number is used.

This fixes the issue that if Wi-Fi is stopped from a shutdown handler,
the code in connect.c tries to reconnect, and fails because Wi-Fi is
already stopped.
Also make the error check in connect.c less strict.

Test services may cause confussion (and did cause some GitHub/forum issues). This update runs test services only when example executed in ci. Also host name is a simple config entry if executed outside of ci.

* Use "example" in all example function & variable names,
ie use i2c_example_xxx instead of i2c_xxx for example functions.
Closes#198https://github.com/espressif/esp-idf/issues/198
* Mark example functions, etc. static
* Replace uses of "test" & "demo" with "example"
* Split the UART example into two
* Rename "main" example files to end with "_main.c" for disambiguation

nvs_flash_init may return an error code in some cases, and applications
should check this error code (or at least assert on it being ESP_OK, to
make potential issues more immediately obvious).
This change modifies all the examples which use NVS to check the error
code. Most examples get a simple ESP_ERROR_CHECK assert, while NVS
examples, OTA example, and NVS unit tests get a more verbose check which
may be used in real applications.
