When printing nothing for the diagnostic on PASS/FAIL, use a string format
with an empty string, not an empty format with a NULL parameter. Clang
complains about the empty format string, which in turn breaks building
with -Werror.

When logging an error from calling waitpid() on the child we print a
misleading error message saying that the error we report was returned by
the chilld. Fix this to say the error is from waitpid().

Description: PGP
Modifies ucall handling for SEV-ES VMs. Instead of using an out
instruction and storing the ucall pointer in RDI, SEV-ES guests use a
outsb VMGEXIT to move the ucall pointer as the data. Allows for SEV-ES
to use ucalls instead of relying the SEV-ES MSR based termination protocol.
Cc: Vishal
Add GHCB management functionality similar to the ucall management.
Allows for selftest vCPUs to acquire GHCBs for their usage.

Some tests, such as the MPTCP bpf tests, require send_recv_data helper
to run in nonblock mode.
This patch adds nonblock support for send_recv_data(). Check if it is
currently in nonblock mode, and if so, ignore EWOULDBLOCK to continue
sending and receiving.

v3:
- add two more patches.
- use log_err instead of ASSERT in v3.
- let send_recv_data return int as Martin suggested.
v2:
Address Martin's comments for v1 (thanks.)
- drop patch 1, "export send_byte helper".
- drop "WRITE_ONCE(arg.stop, 0)".
- rebased.
