If the TLS server (e.g., openssl) closes connection with encrypted close-notify alert
then `errno` is not explicitly set on the socket by LwIP stack.
For this scenario, we must rely only on `ERR_TCP_TRANSPORT_CONNECTION_CLOSED_BY_FIN`
return value as the connection close case and do the graceful connection closure.

This reverts commit 04ac8e43dbaf37e42452fef034606ae3f04e644b.
When `http_on_header_event` is called, event_handler is invoked and
then the current header key and header value are freed. In the previous
approach, `http_on_header_event` was called from `http_on_header_value`,
but it lead to an issue where if the value is received in multiple chunks,
then the current header key and value were freed and thus header was not
processed correctly which might result in connection issues. Calling
`http_on_heaher_event` from `http_on_header_field` ensures that the current
header field and value are processed properly

Foundation transport contained TCP properties for both TCP and SSL
transport, so it was enough to set the TCP connection properties
(keepalive, interface binding) to one transport only. After merging
5778a7c7 we have separate TCP properties for these transports and need
to set the same for both.
This commit also fixes unnecessary allocation of 1 more byte for if_name
Closes https://github.com/espressif/esp-protocols/issues/322
In case of `esp_http_client_read` based workflow, we cache data that is received
during fetch header stage. In case, there is URL redirection and we have to close
the connection on URL, port change then we must discard earlier cached data.
Closes AUD-4158
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)
- Allows users to manually intercept and process the HTTP redirection
when disable_auto_redirect (from the esp_http_client handle) is set to true
Closes https://github.com/espressif/esp-idf/issues/8029
Reason:
For example, if an url is lack of leading 'http:' by mistake, it causes to http_parser_parse_url() cannot parse http host item,
and then pass the null host pointer to _get_host_header(), crash happens.
Fix:
http added null pointer check now.
Closes https://jira.espressif.com:8443/browse/ESPAT-953
For https connection `ESP_TLS_ERR_SSL_WANT_READ` of esp_transport_read was getting treated as error.
Treated this as a timeout to fix connection abort issue!
Also handled http connection EAGAIN with `errno == EAGAIN` check.
