060066804a esp32/modnetwork: Add "reconnects" option to WLAN STA interface.
This adds a wlan.config(reconnects=N) option to set the number of reconnect
attempts that will be made if the WLAN connection goes down.  The default
is N=-1 (infinite retries, current behavior).  Setting
wlan.config(reconnects=0) will disable the reconnect attempts.

A nice side effect of reconnects=0 is that wlan.status() will report the
disconnect reason now.  See related issue #5326.

48437cec45 esp32/network_lan: Add Ethernet support for IDF v4.1 and above.
Ethernet-PHYs from ESP-IDF (LAN8720, IP101, RTL8201, DP83848) are now
supported in IDF v4.1 and above.  PHY_KSZ8041 is only for ESP-IDF 4.3 and
above.  ESP32S2 is not supported.

ecb36d2439 esp32/modnetwork: Re-enable PPP support for IDF-SDK >=v4.
PPP support was disabled in 96008ff59a -
marked as "unsupported" due to an early IDF v4 release.  With the currently
supported IDF v4.x version - 4c81978a - it appears to be working just fine.

ad7213d3c3 py: Add mp_raise_msg_varg helper and use it where appropriate.
This commit adds mp_raise_msg_varg(type, fmt, ...) as a helper for
nlr_raise(mp_obj_new_exception_msg_varg(type, fmt, ...)).  It makes the
C-level API for raising exceptions more consistent, and reduces code size
on most ports:

96008ff59a esp32: Support building with ESP IDF 4.0-beta1.
This commit adds support for a second supported hash (currently set to the
4.0-beta1 tag).  When this hash is detected, the relevant changes are
applied.

This allows to start using v4 features (e.g. BLE with Nimble), and also
start doing testing, while still supporting the original, stable, v3.3 IDF.

Note: this feature is experimental, not well tested, and network.LAN and
network.PPP are currently unsupported.

tcpip_adapter_get_hostname() but should eventually be configurable.

b80bccccff esp32/modnetwork: Still try to reconnect to WLAN even with AUTH_FAIL.
WIFI_REASON_AUTH_FAIL does not necessarily mean the password is wrong, and
a wrong password may not lead to a WIFI_REASON_AUTH_FAIL error code.  So to
improve reliability connecting to a WLAN always reconnect regardless of the
error.

21f9329d5d esp32/modnetwork: Fix wifi.isconnected to return False after disconnect.
esp_wifi_connect will return ESP_OK for the normal path of execution which
just means the reconnect is started, not that it is actually reconnected.
In such a case wifi.isconnected() should return False until the
reconnection is complete.  After reconnect a GOT_IP event is called and it
will change wifi_sta_connected back to True.

039f196c56 esp32/modnetwork: Fix isconnected() when using static IP config.
Currently <WLAN>.isconnected() always returns True if a static IP is set,
regardless of the state of the connection.

This patch introduces a new flag 'wifi_sta_connected' which is set in
event_handler() when GOT_IP event is received and reset when DISCONNECTED
event is received (unless re-connect is successful).  isconnected() now
simply returns the status of this flag (for STA_IF).

The pre-existing flag misleadingly named 'wifi_sta_connected" is also
renamed to 'wifi_sta_connect_requested'.

Fixes issue #3837

bc08c884a2 esp32: Add new port to Espressif ESP32 SoC.
This commit is a combination of 216 commits from the initial stages of
development of this port, up to and including the point where the code was
moved to the ports/esp32 directory.  These commits were mostly concerned
with setting up the build system and getting a reliable port working with
basic features.  The following is a digest of the original commits in their
original order (most recent listed first), grouped where possible per
author.  The list is here to give credit for the work and provide some
level of traceability and accountability.  For the full history of
development please consult the original repository.

  esp32: Add PWM support via machine.PWM class.

  Code lineage:
  I started by copying the esp8266 machine_pwm.c. I used information from the
  ESP32 Technical Reference Manual, the esp-idf documentation, and the SDK's
  sample ledc example code (but I did not copy that code, just studied it to
  understand the SDK's API for PWM). So aside from the code copied from the
  esp8266 PWM support, everything else you see is just new code I wrote.

  I wasn't an employee of anybody when I wrote it, and I wrote it with the
  understanding and intention that it's simply a derivative work of the
  existing micropython code. I freely and willingly contribute it to the
  project and intend that it not change the legal status of the micropython
  code base in any way, even if it is included in that base in whole or part.
