Steffen Eiden 972d4fe0a5 pvattest: Improve logging
Change the name of `hexdump´ to `pvattest_log_bytes´. Additionally, allow
that function to dump the bytes as a single hexadecimal number.

Change the name of `printf_hexdump´ to `pvattest_hexdump´.

Steffen Eiden 3ab06d77fb pvattest: Create, perform, and verify attestation measurements
pvattest is a tool to attest an IBM Secure Execution guest.

In a trusted environment, one can create a request using
`pvattest create`. To get a measurement of an untrusted
IBM Secure Execution guest call 'pvattest perform'.
Again in a trusted environment, call 'pvattest verify'
to verify that the measurement is the expected one.

The tool runs on s390 and x86.
It has the same requirements like libpv and therefore
requires openssl v1.1.1+, glib2.56+, and libcurl.
Additionally, to measure, the linux kernel must provide
the Ultravisor userspace interface `uvdevice` at /dev/uv
and must be executed  on an IBM Secure Execution guest on
hardware with Ultravisor attestation support, like IBM z16 or later.
