Since 5084091a, @tmp is filled by a g_key_file_get_string which is
now an allocated string as opposed to some hash table lookup value,
so we need to treat it as so.

Now that 100% of libvirt code is forbidden in a SUID environment,
we no longer need to worry about whether env variables are
trustworthy or not. The virt-login-shell setuid program, which
does not link to any libvirt code, will purge all environment
variables, except $TERM, before invoking the virt-login-shell-helper
program which uses libvirt.

All of the ones being removed are pulled in by internal.h. The only
exception is sanlock which expects the application to include <stdint.h>
before sanlock's headers, because sanlock prototypes use fixed width
int, but they don't include stdint.h themselves, so we have to leave
that one in place.

Unconditional use of getenv is not secure in setuid env.
While not all libvirt code runs in a setuid env (since
much of it only exists inside libvirtd) this is not always
clear to developers. So make all the code paranoid, even
if it only ever runs inside libvirtd.

Previously a connection object was required to retrieve the auth
credentials. This patch adds the option to call the retrieval functions
only using the connection URI or path to the configuration file. This
will allow to use this toolkit to request passwords for ssh
authentication in the libssh2 connection driver.
Changes:
*virAuthGetConfigFilePathURI(): use URI to retrieve the config file path
*virAuthGetCredential(): Remove the need to propagate conn object
virAuthGetPasswordPath():
*virAuthGetUsernamePath(): New functions, that use config file path
instead of conn object
The source code base needs to be adapted as well. Some files
include virutil.h just for the string related functions (here,
the include is substituted to match the new file), some include
virutil.h without any need (here, the include is removed), and
some require both.
When auto-probing hypervisor drivers, the conn->uri field will
initially be NULL. Care must be taken not to access members
when doing auth lookups in the config file

No check for conn->uri being NULL in virAuthGetConfigFilePath (valid
state) made the client segfault. This happens for example with these
settings:
- no virtualbox driver installed (modifies conn->uri)
- no default URI set (VIRSH_DEFAULT_CONNECT_URI="",
LIBVIRT_DEFAULT_URI="", uri_default="")
- auth_sock_rw="sasl"
- virsh run as root
That are unfortunately the settings with fresh Fedora 17 installation
with VDSM.
The check ought to be enough as conn->uri being NULL is valid in later
code and is handled properly.

* Allows sharing a home directory between different machines, or
sessions (eg. using NFS)
* Cleanly separates cache, runtime (eg. sockets), or app data from
user settings
* Supports performing smart or selective migration of settings
between different OS versions
* Supports reseting settings without breaking things
* Makes it possible to clear cache data to make room when the disk

* Allows us to write a robust and efficient backup solution
* Allows an admin flexibility to change where data and settings are stored
* Dramatically reduces the complexity and incoherence of the
