Use "virNWFilterObj" as a prefix for any external API in virnwfilterobj

In an effort to be consistent with the source module, alter the function
prototypes to follow the similar style of source with the "type" on one
line followed by the function name and arguments on subsequent lines with
with argument getting it's own line.

Alter the format of the code to follow more recent style guidelines of
two empty lines between functions, function decls with "[static] type"
on one line followed by function name with arguments to functions each
on one line.

Move all the NWFilterObj API's into their own module virnwfilterobj
from the nwfilter_conf

Purely code motion at this point, plus adjustments to cleanly build.

Rather than pass the nwfilter object, just pass the def to the function

There's no need to pass the driver pointer to nwfilter_conf, just
pass the configDir.

Found by Coverity. Because there's an "if ((cur = strstr(base, "revision"))
 != NULL) {" followed by a "base = cur" coverity notes that 'base' could
then be NULL causing the return to the top of the "while ((tmp_base =
strstr(base, "processor")) != NULL) {" to have strstr deref a NULL 'base'
pointer because the setting of base at the bottom of the loop is unconditional.

Alter the code to set "base = cur" after processing each key. That will
"ensure" that base doesn't get set to NULL if both "cpu" and "revision"
do no follow a "processor".

While a /proc/cpuinfo file that has a "processor" key but with neither
a "cpu" nor a "revision" doesn't seem feasible, the code is written as if
it could happen, so we have to account for it.

Calls to virFileReadAll after a VIR_ALLOC that return NULL all show
a memory leak since 'ret' isn't virSysinfoDefFree'd and normal path
"return ret" doesn't free outbuf.

Since the kernel does not report much data for that box the sysinfo
output is comparatively sparse.

There's no reason why we should avoid running all sysinfo tests on all
platforms. Refactor the test to get rid of the conditionally compiled
cruft.

virSysinfoSetup should be used only in tests so it can be moved to the
new header file rather than using an extern declaration.

Whole implementations along with helper totalling screens of code were
conditionally compiled. That made the code totally unreadable and
untestable. Rename functions to have the architecture in the name so
that all can be compiled at the same time and introduce header to allow
testing them all.

Proposed formal coding conventions encourage defining typedefs for
vir[Blah] and vir[Blah]Ptr separately from the associated struct named
_vir[Blah]:

    typedef struct _virBlah virBlah;
    typedef virBlah *virBlahPtr;
    struct _virBlah {
    ...
    };

At some point in the past, I had submitted several patches using a
more compact style that I prefer, and they were accepted:

    typedef struct _virBlah {
        ...
    } virBlah, *virBlahPtr;

Since these are by far a minority among all struct definitions, this
patch changes all those definitions to reflect the style prefered by
the proposal so that there is 100% consistency.

Test virSystemd APIs twice to check the cache effects.

After the system has been booted, it should not change.

Cache the return value of virSystemdHasMachined.
Allow starting and terminating machines with just one
DBus call, instead of three, reducing the chance of
the call timing out.

Also introduce a small function for resetting the cache
to be used in tests.

This hides the unused third parameter from every line
and prepares for resetting the environment after each test
case in the future.

Both virSystemdTerminateMachine and virSystemdCreateMachine
propagate the error to tell between a non-systemd system
and a hard error.

In virSystemdGetMachineNameByPID both are treated the same,
but an error is ignored by the callers.

Split out the checks into a separate function.

Make common helpers testNetworkObjFindByUUID and testStoragePoolObjFindByUUID
which will replace the repeated patter for each to find objects by UUID.

As a bonus, the error message processing will also provide the failed uuidstr
rather than a generic error message.

Rather than have multiple places using the same pattern to find
a network by name using virNetworkObjFindByName, create a common
helper which will provide a consistent error message as well.

Rather than have continued repeated sequences of :

    testDriverLock()
    xxx = vir*ObjFindByName()
    testDriverUnlock()

    if (xxx == NULL) {
        virReportError
        goto cleanup;
    }

Make some common helpers which will use the pattern and make a single
reference using a single common error message.

Altered for Interfaces, Storage Pools, Storage Volumes, and Node Devices.

For each the common error message can now also indicate which 'name' was
not found. For Storage Volumes, the "new" error will be more specific
rather than just invalid argument.

In an effort to be consistent with the source module, alter the function
prototypes to follow the similar style of source with the "type" on one
line followed by the function name and arguments on subsequent lines with
with argument getting it's own line.

Use "virInterfaceObj" as a prefix for any external API in virinterfaceobj

Alter the format of the code to follow more recent style guidelines of
two empty lines between functions, function decls with "[static] type"
on one line followed by function name with arguments to functions each
