[PULL 2/6] qga: Refactor guest-exec capture-output to take enum

[Konstantin Kostiuk]

From: Daniel Xu <dxu@dxuuu.xyz>

Previously capture-output was an optional boolean flag that either
captured all output or captured none. While this is OK in most cases, it
lacks flexibility for more advanced capture cases, such as wanting to
only capture stdout.

This commits refactors guest-exec qapi to take an enum for capture mode
instead while preserving backwards compatibility.

[PULL 3/6] qga: Add `merged` variant to GuestExecCaptureOutputMode

[Konstantin Kostiuk]

From: Daniel Xu <dxu@dxuuu.xyz>

Currently, any captured output (via `capture-output`) is segregated into
separate GuestExecStatus fields (`out-data` and `err-data`). This means
that downstream consumers have no way to reassemble the captured data
back into the original stream.

This is relevant for chatty and semi-interactive (ie. read only) CLI
tools.  Such tools may deliberately interleave stdout and stderr for
visual effect. If segregated, the output becomes harder to visually
understand.

This commit adds a new enum variant to the GuestExecCaptureOutputMode
qapi to merge the output streams such that consumers can have a pristine
view of the original command output.

[PULL 4/6] qga: test: Add tests for `merged` flag

[Konstantin Kostiuk]

From: Daniel Xu <dxu@dxuuu.xyz>

This commit adds a test to ensure `merged` functions as expected.
We also add a negative test to ensure we haven't regressed previous
functionality.

[PULL 5/6] qga/commands-win32.c: Drop the check for _WIN32_WINNT >= 0x0601

[Konstantin Kostiuk]

From: Thomas Huth <thuth@redhat.com>

All current versions of glib require _WIN32_WINNT set to 0x0601
or higher already, and we also use this value as a minimum in our
osdep.h header file, so there is no way to still compile this code
with an older version of the Windows ABI. Thus we can drop this
check now.

[PULL 6/6] qga: Fix suspend on Linux guests without systemd

[Konstantin Kostiuk]

From: Mark Somerville <mark@qpok.net>

Allow the Linux guest agent to attempt each of the suspend methods
(systemctl, pm-* and writing to /sys) in turn.

Prior to this guests without systemd failed to suspend due to
`guest_suspend` returning early regardless of the return value of
`systemd_supports_mode`.

Please adjust your .git/config to use url=https and pushurl=git@
so that you automatically get an https:// url here.

Fixed by hand while applying, so no need to re-send now.

Thanks, Richard. It was ok to use git@ URL last time but not a problem to
fix.


Best Regards,
