The return value of virDomainControllerFind >=0 means that
the specific controller was found.
But some functions invoke it and treat 0 as not found.
This patch fix these incorrect invocation.

Since commit 297c99a5 an invalid source definition XML of a character
device that is used as backend for RNG devices, smartcards and redirdevs
causes crash of the daemon when parsing such a definition.
The device types mentioned above are not a part of a regular character
device but are backends for other types. Thus when parsing such device
NULL is passed as the argument @chr_def. Later when checking the
validity of the definition @chr_def was dereferenced when parsing a UNIX
socket backend with missing path of the socket and crashed the daemon.
Sample offending configuration:
<devices>
...
<rng model='virtio'>
<backend model='egd' type='unix'>
<source mode='bind' service='1024'/>
</backend>
</rng>
</devices>

- Move COPYING* to libvirt-client, so every package pulls them in
- Move AUTHORS ChangeLog.gz NEWS README TODO from -daemon to -docs
- Drop duplicate distribution of docs in -python

When passing in custom driver XML, allow a block like
<domain xmlns:test='http://libvirt.org/schemas/domain/test/1.0'>
...
<test:runstate>5</test:runstate>
</domain>
This is only read at initial driver start time, and sets the initial
run state of the object. This is handy for UI testing.
It's only wired up for domains, since that's the only conf/
infrastructure that supports namespaces at the moment.
The virnetmessagetest code did not check for failure to
allocate the message object. This lead to a crash on OOM
in the test suite.

For inexplicable reasons, the nwfilter XML parser is intentionally
ignoring errors that arise during parsing. As well as meaning that
users don't get any feedback on their XML mistakes, this will lead
it to silently drop data in OOM conditions.

Normally a lockspace resource is not freed while there are
active owners. During initial resource creation though, an
OOM error will trigger this scenario. virLockSpaceResourceFree
was not freeing the 'owners' field in this case.

Several places in virInterfaceDefParseProtoIPv6 clobber the
default 'ret' return value. So when jumping to cleanup on
error, 'ret' may mistakenly be set to 0 instead of -1. This
caused failure to report OOM errors, meaning data was silently
lost during parsing.

If qemuParseCommandLine finds an arg it does not understand
it adds it to the QEMU passthrough custom arg list. If the
qemuParseCommandLine method hits an error for any reason
though, it just does 'VIR_FREE(cmd)' on the custom arg list.
This means all actual args / env vars are leaked. Introduce
a qemuDomainCmdlineDefFree method to be used for cleanup.

If the call to virDomainControllerInsert fails in

The 'qemuStringToArgvEnv' method splits up a string of command
line env/args to an 'arglist' array. It then copies env vars
to a 'progenv' array and args to a 'progargv' array. When
copyin the env vars, it NULL-ifies the element in 'arglist'
that is copied.
Upon OOM the 'virStringListFree' is called on progenv and
arglist. Unfortunately, because the elements in 'arglist'
related to env vars have been set to NULL, the call to
virStringListFree(arglist) doesn't free anything, even
though some non-NULL args vars still exist later in the
array.
To fix this leak, stop NULL-ifying the 'arglist' elements,
and change the cleanup code to only free elements in the
'arglist' array, not 'progenv'.
