Sometimes, an asynchronous helper is started (such as a compressor or iohelper program), but a later error means that we want to abort that child. Make this easier.
Note that since daemons and virCommandRunAsync can't mix, the only time virCommandFree can reap a process is if someone did virCommandRunAsync for a non-daemon and didn't stash the pid.
* src/util/command.h (virCommandAbort): New prototype. * src/util/command.c (_virCommand): Add new field. (virCommandRunAsync, virCommandWait): Track whether pid was used. (virCommandFree): Reap child if caller did not request pid. (virCommandAbort): New function. * src/libvirt_private.syms (command.h): Export it. * tests/commandtest.c (test19): New test. ---
v2: no change, but by adding patch 2, it should make it clear that this patch is doing the right thing about not reaping a long-running daemon.
