Per WiFi library requirement, SSID can be non-null terminated string
if its length goes to 32 bytes (maximum). Use of strncpy in this case,
along with compiler optimization level -O2 results in some warnings
for potential use of non-null terminated strings.
Fix here ensures use of memcpy to copy SSID string upto appropriate
desired length. This helps to avoid compiler specific workaround
flags added earlier.

esp_netif_init() returns standard esp_err_t error code (unlike tcpip_adapter init), so shall be checked for the return value
Also to make the initialization code more consistent.
The build system automatically determines offsets of partitions from
the partition table, so no manual changes are needed. Instead, add a
note that partition offsets may need to be updated when increasing
the bootloader size.
Other changes:
* Command line argument name and descriptions updated and formatted
* Some exception messages updated for clarity
* READMEs updated for tool and all provisioning examples
* Minor update in example test scripts due to change in esp_prov.get_transport() API
* Transport_HTTP now forces connect on initialization
- Adds NimBLE stack support to existing BLE variant of unified provisioning.
- Uses scan response to send device name, 128 bit custom UUIDs based on service
UUID.
- Minimal changes to `app_prov.c`, component.mk, CMakeLists.txt and
`protocomm_ble.h` to accomodate NimBLE stack for provisioning.
Removed all other instances of call to esp_wifi_init(), because every time this is called it
will override its previously set default event handler and hence cause numerous warnings.
Also, call nvs_flash_init() only once, that is before calling esp_wifi_init() in main function
Note : Examples have been updated to prevent invocation of bluedroid/wifi APIs from inside timer callback when stopping provisioning. Workaround is to spawn new task from inside the timer callback.
* BLE and softAP provisioning examples added along with tests.
* An application specific example added for demonstrating custom provisioning scheme.
* tools/esp_prov/esp_prov.py can be used as a provisioning client for SoftAP, BLE and CLI based transports.
