Introduce a new set of helpers including a new data structure which
simplifies keeping and construction of lists of typed parameters.

The use of VIR_RESIZE_N in the virTypedParamsAdd API has performance
benefits but requires passing around 3 arguments. Use of them lead to a
set of macros with embedded jumps used in the qemu statistics code.

This patch introduces 'virTypedParamList' type which aggregates the
necessary list-keeping variables and also a new set of functions to add
new typed parameters to a list.

These new helpers use printf-like format string and arguments to format
the argument name as the stats code often uses indexed typed parameters.

The accessor function then allows extracting the typed parameter list in
the same format as virTypedParamsAdd* functions would do.

One additional benefit is also that the list function can easily be used
with VIR_AUTOPTR.

Missing semicolon at the end of macros can confuse some analyzers

Drop the semicolon from the final statement of the macro, so

For any file ending priv.h, before the #ifndef, we will require a

Same as for deserializer, this method might get handy for admin one day.
The major reason for this patch is to stay consistent with idea, i.e.
when deserializer can be shared, why not serializer as well. The only
problem to be solved was that the daemon side serializer uses a code
snippet which handles sparse arrays returned by some APIs as well as
removes any string parameters that can't be returned to older clients.
This patch makes of the new virTypedParameterRemote datatype introduced
by one of the pvious patches.

Since the method is static to remote_driver, it can't even be used by our
daemon. Other than that, it would be useful to be able to use it with admin as
well. This patch uses the new virTypedParameterRemote datatype introduced in
one of previous patches.

Currently, the deserializer is hardcoded into remote_driver which makes
it impossible for admin to use it. One way to achieve a shared implementation
(besides moving the code to another module) would be pass @ret_params_val as a
void pointer as opposed to the remote_typed_param pointer and add a new extra
argument specifying which of those two protocols is being used and typecast
the pointer at the function entry. An example from remote_protocol:

struct remote_typed_param_value {
        int type;
        union {
                int i;
                u_int ui;
                int64_t l;
                uint64_t ul;
                double d;
                int b;
                remote_nonnull_string s;
        } remote_typed_param_value_u;
};
typedef struct remote_typed_param_value remote_typed_param_value;

struct remote_typed_param {
        remote_nonnull_string field;
        remote_typed_param_value value;
};

That would leave us with a bunch of if-then-elses that needed to be used across
the method. This patch takes the other approach using the new datatype
introduced in one of earlier commits.

Both admin and remote protocols define their own types
(remote_typed_param vs admin_typed_param). Because of the naming convention,
admin typed params wouldn't be able to reuse the serialization/deserialization
methods, which are tailored for use by remote protocol, even if those method
were exported properly. In that case, introduce a new internal data type
structurally copying both admin and remote protocols which, eventually, would
allow serializer and deserializer to be used in a more generic way.

All APIs that take typed parameters are only using params address in
their entry point debug messages. With the new VIR_TYPED_PARAMS_DEBUG
macro, all functions can easily log all individual typed parameters
passed to them.

This API is useful for checking whether only a specific subset of
supported typed parameters were passed.

The function is just a renamed public version of former
virTypedParameterArrayClear.

This patch adds a helper to deal with assigning values to
virTypedParameter structures from strings. The helper parses the value
from the string and assigns it to the corresponding union value.

The driver uses OpenWSMAN to directly communicate with a Hyper-V
server over its WS-Management interface exposed via Microsoft WinRM.

The driver is based on the work of Michael Sievers. This started in
the same master program project group at the University of Paderborn
as the ESX driver.

See Michael's blog for details: http://hyperv4libvirt.wordpress.com/

Add a generator script to generate the structs and serialization
information for OpenWSMAN.

openwsman.h collects workarounds for problems in OpenWSMAN <= 2.2.6.
There are also disabled sections that would use ws_serializer_free_mem
but can't because it's broken in OpenWSMAN <= 2.2.6. Patches to fix
this have been posted upstream.

Replace 'method' with 'function' and get the filename's suffix right.
