Commit Message

Markus Armbruster July 6, 2020, 8:09 a.m. UTC 
The previous commit enables conversion of

    foo(..., &err);
    if (err) {
        ...
    }

to

    if (!foo(..., &err)) {
        ...
    }

for QemuOpts functions that now return true / false on success /
error.  Coccinelle script:

A few line breaks tidied up manually.
