[ima-evm-utils,v2,00/12] address deprecated warnings

Message

Between travis/ci and OpenSSL v3 a large number of deprecated warnings
are being emitted when compiling ima-evm-utils.  Start addressing these
deprecated warnings by replacing the low level SHA1 and HMAC calls with
the EVP_ functions.  IMA signature version 1 also uses low level calls,
but instead of fixing it, deprecate it as nobody should be using it
anyway.

OpenSSL v3 "engine" support is deprecated and replaced with "providers".
Engine support will continue to work for a while, but results in
deprecated declaration and other messages.  Define a "--disable-engine"
and the equivalent "--enable-engine=no" configuration option.

Changelog v2:
- Based on Vitaly's comments, base enabling engine support on
OPENSSL_NO_ENGINE/OPENSSL_NO_DYNAMIC_ENGINE support.  Also don't limit
disabling ima-evm-utils engine support to v3, make it generic.
- Added Stefan's Reviewed-by tags.

Changelog v1:
- Based on Stefan's comments, removed deprecated functions when not
used and added missing word. Updated the usage and options accordingly.
- Based on Vitaly's comments, explicitly require "--disable-engine"
configuration to compile ima-evm-utils without OpenSSL v3 engine support
and typo.
- Based on Petr's comments, addressed the "return 77" by removing it,
  updated the travis patch description, and added his Reviewed-by tags.

Mimi Zohar (12):
