`pkg-config` is a well established tool and all of our required
libraries do provide .pc files. Therefore let's declare `pkg-config` as
required and use it. In addition, remove now useless code.

It's often useful to know how much data was actually copied, therefore let's
introduce an nullable parameter `@copied` to `pv_gbytes_memcpy`.

Use `PV_CERT_ERROR` error domain whenever useful. Currently, it's only used
internally in libpv and therefore there is no problem in changing it.

Fixes a bug that make still tried to build libpv even when the
compilation of libpv was turned off.
This lead to a build bug when one of the dependencies was not met.
Also fixes the check of the OpenSSL version at build time.i

pv_BIO_reset() wrongfully handled the BIO_reset() rc for non-file-backed BIOs.
This is currently not an issue as the only non-file BIO used cannot fail
at BIO_reset()

The current implementation drops the reason why a download of a CRL
failed. This is changed to the reporting of the error triggered by the
last CRL download attempt.
This mainly helps to check for the download error during CI testing
and prevent connectivity issues to be the reason of a test failure.

libpv is a collection of definitions and functions related to
Protected Virtualization (PV).
The functions cover mainly encryption (e.g. AES-GCM)
and certificates (X509). There are also helping functions for glib2.
Most of the code is extracted+refactored from `genprotimg`, which
will use this library in future.
Requires openssl v1.1.1+, glib2.56+, and libcurl.
libpv is not designed or intended to be dynamically linked or used
outside of this project. Its purpose is to avoid code duplication
as PV tools do very similar things regarding cryptography.
