Andrew Cooper 869aeb7f02 tools: Introduce a xc_xenver_buildid() wrapper
... which converts binary content to hex automatically.

Update libxl to match.  No API/ABI change.

This removes a latent libxl bug for cases when the buildid is longer than 4092
bytes.

Andrew Cooper 504ea442e3 tools: Introduce a non-truncating xc_xenver_extraversion()
... which uses XENVER_extraversion2.

In order to do this sensibly, use manual hypercall buffer handling.  Not only
does this avoid an extra bounce buffer (we need to strip the xen_varbuf_t
header anyway), it's also shorter and easlier to follow.

Update libxl and the ocaml stubs to match.  No API/ABI change in either.

With this change made, `xl info` can now correctly access a >15 char
extraversion:

  # xl info xen_version
  4.18-unstable+REALLY LONG EXTRAVERSION

Andrew Cooper 583a0fb0fa tools/libxc: Move xc_version() out of xc_private.c into its own file
kexec-tools uses xc_version(), meaning that it is not a private API.  As we're
going to extend the functionality substantially, move it to its own file.
