- Made tcp_transport_errors codes public to indicate
TCP connection issues not covered in socket's errno
- Added API to translate tcp_transport_error codes
to esp_err_t codes for TCP Transport

lwip was added to common requirements list to provide "sys/socket.h"
header to all components without additional requirements specified.
However, lwip pulls in a lot of dependencies on other components.
This commit removes lwip from common requirements to reduce the number
of components in G1-only apps.
To compensate for this removal, the following changes are made:
- newlib (which is a common requirement) has a public dependency on
lwip if lwip is present in the build. This ensures that sys/socket.h
is available as long as lwip component is included into the build.
- lwip is now a public requirement of esp-tls since esp_tls.h includes
sys/socket.h header.
- lwip is now a public requirement o esp_http_client because
sys/socket.h is included from esp_http_client.h
- lwip is now a private requirement of esp_wifi for "smartconfig_ack"
- lwip is now a private requirement of mqtt for socket functions
- lwip is now a public requirement of tcp_transport because
esp_transport_tcp.h includes sys/socket.h header.
- mbedtls checks if lwip component is present in the build. If yes,
net_sockets.c is added to the build, along with the dependency on
lwip. Previously lwip was a public requirement of mbedtls
unconditionally.
system/g1_components test app is updated to reflect the changes
Default public dependencies of a component before and after this
change, except common requirements:
- esp_timer (public dependency of freertos)
- bootloader_support (public dependency of esp_hw_support)
- vfs (public dependency of lwip)
- esp_wifi (public dependency of lwip)
- esp_event (public dependency of esp_wifi)
- esp_netif (public dependency of esp_event)
- esp_eth (public dependency of esp_netif)
- esp_phy (public dependency of esp_wifi)
After:
- esp_timer (public dependency of freertos)
- bootloader_support (public dependency of esp_hw_support)
Altogether, the following components have been always added as
public requirements to all other components, and are not added now
([breaking-change]):
- lwip
- vfs
- esp_wifi
- esp_event
- esp_netif
- esp_eth
- esp_phy
Application components now need to explicitly declare dependencies on
these components.
Documentation was incorrectly point that we return the socket number.
The function returns an integer related to the status of the connection.

Also added parameter checks if used from as a public API
and updated the `is_plein_tcp` description that it's possible to connect
directly using plain tcp transport with the new API.
Add missing NULL test for esp_transport_init() call.
Otherwise, it will hit NULL pointer dereference when assign t->_get_socket.

For compatibility reasons, support also transports separately if the transport is used
before attaching to parent list. In this case we create an internal context which is
independent on the foundation transport and used preferably
Transport's error_handle is used to capture different types of errors
including esp_err_t from esp-tls and socket/system errors.
This change adds the following error codes for TCP transport:
* connection closed by a FIN flag (clean closure from server)
* DNS resolution problem
* connection timeout
These errors are already defined in esp-tls component and since this
component will be used in the future for both TCP and SSL transport, we
currently report these issues in transport::error_handle::esp_tls_last_error
of standard esp error type (esp_err_t)
