dns_over_https/main includes time_sync.h, nvs_flash.h, esp_event.h,
esp_timer.h, and mbedtls headers. Declare nvs_flash, esp_event,
esp_timer, mbedtls and time_sync in PRIV_REQUIRES so the build is
self-describing under any build system.
Also move esp_netif from PRIV_REQUIRES to REQUIRES in
protocol_examples_common, since its public header exposes esp_netif.h.
Also add the PRIVATE keyword to target_link_libraries in the
dns_over_https component — CMake rejects mixed keyword/plain
signatures on the same target.
On wifi-disconnect (after all retries), we signal to the IP semaphores
and delete them immediately, while the wait thread might be still
holding on them causing:
```
I (1682) example_connect: Waiting for IP(s)
I (4092) example_connect: Wi-Fi disconnected 201, trying to reconnect...
I (6502) example_connect: WiFi Connect failed 2 times, stop reconnect.
assert failed: spinlock_acquire spinlock.h:142 (lock->count == 0)
```
The intention of the code block was to set MAC address for SPI
Ethernet modules, however !CONFIG_EXAMPLE_USE_INTERNAL_ETHERNET also
affected the case of CONFIG_EXAMPLE_USE_OPENETH.
This commit corrects the code to match the original intention.

Function example_configure_stdin_stdout() was used for simple UART I/O
operation in CI to enter test env configuration (wifi ssid, IPs, etc).
It could be called multiple times, but didn't handle the situation where
we install UART interrupt from multiple source (e.g. in ICMP tests,
where we first need to enter wifi credentials of test AP and then we
start ping-cmd console to handle ping commands)
Fixed memory leak in emac_esp_new_dma function.
Polished ESP EMAC cache management.
Added emac_periph definitions based on SoC features and improved(generalized) ESP EMAC GPIO
initialization.
Added ESP EMAC GPIO reservation.
Added check for frame error condition indicated by EMAC DMA and created a target test.
Fix dependency tree so that lwip doesn't depend on any specific network
interface component.
Network interface drivers shall depend on esp_netif.
esp_netif shall depend on lwip (but not on any specific interface
driver) -- it optionally depends on vfs and esp_eth (need ethernet
header for L2/bridge mode)
* esp-netif to optionally depend on esp-eth (only for l2tap config)
* esp_eth.h now includes the original ethernet header and the
ethernet-netif glue layer
* Updated examples and test to explicitely use esp-eth dependency if
needed
