1) Rename srp component to esp_srp 2) Remove dependency on hkdf sha 3) Restructure protocomm component APIs to make them more flexible for allowing multiple security versions 4) esp_srp: convert API return type from int to esp_err_t 5) esp_srp: Formatting changes 6) Added mbedtls_gcm instead of aes_ctr Co-authored-by: Laukik hase <laukik.hase@espressif.com>
