[libnbd PATCH] rust: Allow rust compilation without rustfmt
by Eric Blake
Our goal is that rustfmt should be an optional dependency. If
present, we use it to make generated .rs files look nicer in the
tarball created by 'make dist'. But if absent, things should still
compile just fine.
However, the configure test currently rejects cargo as unusable if
'cargo fmt' doesn't work, which is overly strict. Not to mention that
'test ... -a ...' is non-portable (we don't need two conditions, but
if we did, the portable spelling is 'test ... && test ...').
Fixes: b2511d640b ("rust: create basic Rust bindings", v1.17.3)
Signed-off-by: Eric Blake <eblake(a)redhat.com>

Pushed as b389eaea, as it lets me complete 'make check' with Rust
bindings enabled but rustfmt not installed.

[PATCH libnbd] copy/copy-file-to-qcow2-compressed.sh: Skip test for all zeroes disk
by Richard W.M. Jones
Occasionally this test will choose a random seed which results in an
all-zeroes disk. The test tries to convert this to a compressed qcow2
file, and fails because no compressed clusters are detected in the
resulting file. This happens because qcow2 stores zero clusters with
a special sparse representation, they are never stored compressed, so
a disk with only zeroes in it will never contain compressed clusters.
To fix this, detect an all-zeroes disk and skip.

[libnbd PATCH] golang: Optionally use gofmt on generated .go files
by Eric Blake
Combine my recent work on improving the generated Go output with
Tage's work on using a canonical formatter for Rust. If gofmt is
available during the build, then the generated .go files will now use
TAB indents and have proper columnar alignment; if it is not
available, the project still compiles.

Followup to this earlier series:
https://listman.redhat.com/archives/libguestfs/2023-July/032133.html
I still need to fold in the 'make check' verification of non-generated
.go files, plus Dan's idea of enabling CI coverage...
