Switching back from data (PPP) mode to command mode must be done is the following sequence:
* No characters entered for T1 time (1 second)
* "+++" characters entered with no characters in between (1 second)
* No characters entered for T1 timer (1 second)
(per specification of SIM800 SIM800_Series_AT_Command_Manual_V1.09.pdf)

Regression from a90817cda0 that caused
parsing exit in case of an unexpected result found (line handler
reported ESP_FAIL). Prevously if any error found in the line handler we
just posted an unexpected event, but continued with parsing. Fixed by
allowing for further parsing.

Due to these problems
* possible race condition, two events competing
* pattern detection work a little different for different IDF versions
* switching between pattern detection and data reading is complicated
* using just data events is easier for porting to a different communication peripheral
These changes were made:
* Removed the UART pattern detection entirely
* Used manual pattern detection after reading plain data from the UART
Closes https://github.com/espressif/esp-idf/issues/7176
These functions are unlikely to be reused, make them static.
Take esp_modem_dce_handle_cbc as an example, it's internal implementation
of esp_modem_dce_get_battery_status, expose esp_modem_dce_get_battery_status
function is enough.

Function esp_modem_netif_clear_default_handlers() didn't unregister
event handlers from IP related events, so if the netif modem was
reinitialized the previous handler was called with already destroyed
esp_netif handle.

To be in line with other interfaces, when deleting the driver and it's glue layer to esp-netif, we DO NOT delete the related esp-netif (since is was allocated and created outside of the glue code and it works the same way in esp-eth and esp-wifi driver/glue layers).
Closes https://github.com/espressif/esp-idf/issues/5486
Reuses most of the code from BG96. At this moment, this is not a
perfect support for other modules as the generic handlers for most
common modem functionality is not easily reusable. Refactoring to a
fully independent modem component will solve this.
Closes https://github.com/espressif/esp-idf/issues/5250
esp-modem netif glue layer implements esp-netif attach callback to setup corresponding driver functions and start the modem. The error code of esp_modem_start_ppp() was ignored and ESP_OK returned in all cases. Fixed by passing esp_modem_start_ppp()'s error code to post_attach callback.
Closes https://github.com/espressif/esp-idf/issues/5430
Also remove event_queue_size from esp_modem_dte_t because
event_queue_size is only used in esp_modem_dte_init.

Basic set of configuration related to UART moved from KConfig
to runtime configuration structure to simplify reusing the component for
testing and examples.
Fixes Guru Meditation Error: Core 0 panic'ed (LoadProhibited) when config with
CONFIG_PM_ENABLE=y && CONFIG_PM_DFS_INIT_AUTO=y.

pppos_client example used the UART default clock configuration which might
cause issues if power management enabled. Settings updated to UART_SCLK_REF_TICK
Also need to explicitly disable RX interrupts in UART pattern detection
mode.
Closes https://github.com/espressif/esp-idf/issues/4801
calling esp_netif_up() and esp_netif_down() was not supported if the
underlying netif wos of ppp type. Updated the code to enable setting
these interfaces up/down and registered actions in moden_netif glue for
connection/disconnection events to set the netif up/down.
When library users call esp_stop_ppp(), it is expected that the PPP link
is closed and the DCE is moved into command mode.
If the STOP event is not posted into the event loop, then the PPP stack
would not be turned off, resulting in the impossibility to switch into
command mode, as the modem is still sending PPP binary data.
