63a3d5b802 aclpolkit.html.in: Kill useless spaces in <pre/>
The <pre/> section is rendered as-is on the page. That is, if all
the lines are prefixed with 4 spaces the rendered page will also
have them. Problem is if we put a box around such <pre/> because
the content might not fix into it.

ca1ac6643e qemuDomainAttachNetDevice: Avoid @originalError leak
Coverity identified that this variable might be leaked. And it's
right. If an error occurred and we have to roll back the control
jumps to try_remove label where we save the current error (see
0e82fa4c34 for more info). However, inside the code a jump onto
other label is possible thus leaking the error object.

e555ed6f7b admin: Use the newly introduced close callback handling helpers
Use the newly introduced close callback helpers to make the code look just a
bit cleaner and more importantly, to fix the following memleak regarding a
dangling virAdmConnect object reference caused by assigning NULL to the close
callback data once the catch-disconnect routine used the callback followed
by a comparison of NULL to the originally defined close callback (which at that
moment had already been NULL'd by remoteAdminClientCloseFunc) in
virAdmConnectCloseCallbackUnregister.

7cea74a3b2 datatypes: Introduce some admin-related close callback handling helpers
Well, there were three different spots where closeCallback->freeCallback was
called, not looking the same --> potential for bugs - and there indeed is a bug
with refcounting of the @conn object. So this patch partially follows the path
set by commit 24dbb69f by introducing some close callback helpers both to
replace all the spots where we call clean the close callback data with a
dedicated function and to be able to fix the refcounting bug causing a memleak.

d46a1e5d45 admin: Remove unnecessary @conn object locking
The only place we change the @conn object is actually virAdmConnectOpen
routine, thus at the moment we don't really need to lock it, given the fact that
what we're trying to do here is to change the closeCallback object which is a
lockable object itself, so that should be enough to avoid races.

b98b3b742b vsh: Drop conditional error reporting in vshErrorHandler
First, since commit 834c5720 the error reporting within the vshErrorHandler
doesn't work because there was a lot of renaming going on (dull mechanical
renaming without much thinking about it, yep - shame on me) and so the original
env variable VIRSH_DEBUG got renamed to VSH_DEBUG which we don't support nor
document anywhere. Second, by specifying this env variable, the last libvirt
error gets reported twice despite the fact we say the error reporting should be
deferred until the command finishes, and last but not least the vintage code's
logic is a bit 'odd', since the error would get reported iff the env variable
is set, even if the value should be equal to our DEFAULT value in which case it
doesn't make sense that we behave differently when an env variable is set to
some value and when there's no env variable at all but we use the same value
automatically as default.

b7798a07f9 qemu: Generate memory device aliases according to slot number
The memory device alias needs to be treated as machine ABI as qemu is
using it in the migration stream for section labels. To simplify this
generate the alias from the slot number unless an existing broken
configuration is detected.

With this patch the aliases are predictable and even certain
configurations which would not be migratable previously are fixed.

ce1ee02a25 qemu: Assign slots to memory devices prior to usage
As with other devices assign the slot number right away when adding the
device. This will make the slot numbers static as we do with other
addressing elements and it will ultimately simplify allocation of the
alias in a static way which does not break with qemu.

93d9ff3da0 qemu: process: detect if dimm aliases are broken on reconnect
Detect on reconnect to a running qemu VM whether the alias of a
hotpluggable memory device (dimm) does not match the dimm slot number
where it's connected to. This is necessary as qemu is actually
considering the alias as machine ABI used to connect the backend object
to the dimm device.

This will require us to keep them consistent so that we can reliably
restore them on migration. In some situations it was currently possible
to create a mismatched configuration and qemu would refuse to restore
the migration stream.

To avoid breaking existing VMs we'll need to keep the old algorithm
though.
