This splits the code in 4 files:
- uencrypt.h
- uencrypt.c - main program
- uencrypt-openssl.c - OpenSSL/wolfSSL implementation
- uencrypt-mbedtls - mbedTLS implementation
Other changes, accounting for ~400 bytes increase in ipk size:
- more error condition checking and reporting,
- hide key and iv command line arguments

The ABI of the wolfssl library changed a bit between version 5.5.3 and
5.5.4. This release update will trigger a rebuild of all packages which
are using wolfssl to make sure they are adapted to the new ABI.

As wolfSSL is having hard time maintaining ABI compatibility between
releases, we need to manually force rebuild of packages depending on
libwolfssl and thus force their upgrade. Otherwise due to the ABI
handling we would endup with possibly two libwolfssl libraries in the
system, including the patched libwolfssl-5.5.1, but still have
vulnerable services running using the vulnerable libwolfssl-5.4.0.
So in order to propagate update of libwolfssl to latest stable release
done in commit ec8fb542ec3e4 ("wolfssl: fix TLSv1.3 RCE in uhttpd by
using 5.5.1-stable (CVE-2022-39173)") which fixes several remotely
exploitable vulnerabilities, we need to bump PKG_RELEASE of all
packages using wolfSSL library.

Modify uencrypt to support any cipher provided by ssl library.
Original tool supported only AES-128-CBC to decrypt the config
mtd of Arcadyan WG430223/WG443223.
TP-Link Deco S4 has mtd configuration encrypted with DES-ECB,
so make the cipher generic to support both routers.

This adds a simple AES-128-CBC encryption/decryption program using
either wolfSSL or OpenSSL as backend to decrypt Arcadyan WG4xx223
configuration partitions. The ipk size is 3,355 bytes.
