esp_http_server: fix return values for `httpd_socket_send()` and `httpd_socket_recv()` APIs
Closes IDFGH-9275
See merge request espressif/esp-idf!22168
Some of the esp_sntp_...() APIs that wrap lwip's SNTP
module use tcpip_callback() to execute the lwip functionality
in the correct state (either with locked TCP/IP core,
or within the TCP/IP thread).
tcpip_callback() however doesn't wait for completion of the callback,
which doesn't prevent from using the stack variables after destroy
if used as a parameter.
Introduced in a71fa82.
Fixed by using of tcpip_api_call() instead of the tcpip_callback().

cpu retention: add riscv core sleep critical and non-critical register layout structure definition
cpu retention: add assembly subroutine for cpu critical register backup and restore
cpu retention: add cpu core critical register context backup and restore support
cpu retention: add cpu core non-critical register context backup and restore support
cpu retention: add interrupt priority register context backup and restore support
cpu retention: add cache config register context backup and restore support
cpu retention: add plic interrupt register context backup and restore support
cpu retention: add clint interrupt register context backup and restore support
cpu retention: wait icache state idle before pmu enter sleep
Initialize the pmu sleep machine constant when pmu is initialized, and calculate
the pmu sleep time adjustment value and hardware configuration value according
to the machine constant during system sleep.
Calibrate fast OSC before each sleep and use the calibration value to calculate
PMU hardware wait cycles when use the fast OSC as the work clock.
Added a cast to esp_sntp_operatingmode_t in sntp_setoperatingmode()'s
call to esp_sntp_setoperatingmode(operating_mode). Althouogh C
doesn't require the cast, C++ does. Otherwise you get...
error: invalid conversion from 'u8_t' {aka 'unsigned char'}
to 'esp_sntp_operatingmode_t'
1. add check in the gdma driver, to prevent multiple channels connecting
to the same peripheral
2. memory copy DMA ID will occupy the peripheral's DMA ID on some ESP
targets (e.g. esp32c3/s3). We should search for a free one when
install async memcpy driver.
