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

[after test: replaced a hardcoded IV size of 16 by cipher_info->iv_size]

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.
