42b2f35d36 esx: Move VMX handling code out of the driver directory
Now the VMware driver doesn't depend on the ESX driver anymore.

Add a WITH_VMX option that depends on WITH_ESX and WITH_VMWARE.
Also add a libvirt_vmx.syms file.

Move some escaping functions from esx_util.c to vmx.c.

Adapt the test suite, ESX and VMware driver to the new code layout.

2a151699f1 esx: Improve error reporting for failed tasks
Instead of just reporting that a task failed get the
localized message from the TaskInfo error and include
it in the reported error message.

Implement minimal deserialization support for the
MethodFault type in order to obtain the actual fault
type.

For example, this changes the reported error message
when trying to create a volume with zero size from

  Could not create volume

to

  Could not create volume: InvalidArgument - A specified parameter was not correct.

Not perfect yet, but better than before.

5699034b65 esx: Use SessionIsActive when available
Before this commit SessionIsActive was not used because ESX(i)
doesn't implement it. vCenter supports SessionIsActive, so use
it here, but keep the fall back mechanism for ESX(i) and GSX.

8fdb0b0c84 esx: Fall back to path as key when QueryVirtualDiskUuid isn't available
QueryVirtualDiskUuid is only available on an ESX(i) server. vCenter
returns an NotImplemented fault and a GSX server is missing the
VirtualDiskManager completely. Therefore only use QueryVirtualDiskUuid
with an ESX(i) server and fall back to path as storage volume key for
vCenter and GSX server.

635f01ae28 esx: Use the VirtualDisk UUID as storage volume key
VirtualDisks are .vmdk file based. Other files in a datastore
like .iso or .flp files don't have a UUID attached, fall back
to the path as key for them.

8c48743b97 esx: Improve object-by-type lookup performance
Instead of using one big traversal spec for lookup use a set of
more fine grained traversal specs that are selected based on the
actual needs of the lookup.

This gives up to 20% speedup for certain operations like domain
listing due to less HTTP(S) traffic.

5254546bba esx: Make storage pool lookup by name and UUID more robust
Don't rely on summary.url anymore, because its value is different
between an esx:// and vpx:// connection. Use host.mountInfo.path
instead.

Don't fallback to lookup by UUID (actually lookup by absolute path)
in esxVI_LookupDatastoreByName when lookup by name fails. Add a
seperate function for this: esxVI_LookupDatastoreByAbsolutePath

e4938ce2f1 esx: Restrict vpx:// to handle a single host in a vCenter
Now a vpx:// connection has an explicitly specified host. This
allows to enabled several functions for a vpx:// connection
again, like host UUID, hostname, general node info, max vCPU
count, free memory, migration and defining new domains.

Lookup datacenter, compute resource, resource pool and host
system once and cache them. This simplifies the rest of the
code and reduces overall HTTP(S) traffic a bit.

esx:// and vpx:// can be mixed freely for a migration.

Ensure that migration source and destination refer to the
same vCenter. Also directly encode the resource pool and
host system object IDs into the migration URI in the prepare
function. Then directly build managed object references in
the perform function instead of re-looking up already known
information.

25e34b703a esx: Improve blocked task detection and fix race condition
esxVI_WaitForTaskCompletion can take a UUID to lookup the
corresponding domain and check if the current task for it
is blocked by a question. It calls another function to do
this: esxVI_LookupAndHandleVirtualMachineQuestion looks up
the VirtualMachine and checks for a question. If there is
a question it calls esxVI_HandleVirtualMachineQuestion to
handle it.

If there was no question or it has been answered the call
to esxVI_LookupAndHandleVirtualMachineQuestion returns 0.
If any error occurred during the lookup and answering
process -1 is returned. The problem with this is, that -1
is also returned when there was no error but the question
could not be answered. So esxVI_WaitForTaskCompletion cannot
distinguish between this two situations and reports that a
question is blocking the task even when there was actually
another problem.

This inherent problem didn't surface until vSphere 4.1 when
you try to define a new domain. The driver tries to lookup
the domain that is just in the process of being registered.
There seems to be some kind of race condition and the driver
manages to issue a lookup command before the ESX server was
able to register the domain. This used to work before.

Due to the return value problem described above the driver
reported a false error message in that case.

To solve this esxVI_WaitForTaskCompletion now takes an
additional occurrence parameter that describes whether or
not to expect the domain to be existent. Also add a new
parameter to esxVI_LookupAndHandleVirtualMachineQuestion
that allows to distinguish if the call returned -1 because
of an actual error or because the question could not be
answered.

50723581b0 esx: Generate most SOAP mapping and improve inheritance handling
The Python script generates the mappings based on the type descriptions
in the esx_vi_generator.input file.

This also improves the inheritance handling and allows to get rid of the
ugly, inflexible, and error prone _base/_super approach. Now every struct
that represents a SOAP type contains a _type member, that allows to
recreate C++-like dynamic dispatch for "method" calls in C.

d304352b19 esx: Generate method mappings via macros
This is actually a consequence of the reworked required parameter
checking: Unify the required parameter check into a Validate function
instead of doing it separately im the (de)serialization part.

The required parameter checking for the mapped methods parameter was
done in the (de)serialize functions before. Now it's explicitly done
in the mapped method itself.

b79aaf91b8 ESX: Don't automatically follow redirects.
The default transport for the VI API is HTTPS. If the server redirects
from HTTPS to HTTP the driver would silently follow that redirection.
The user assumes to communicate with the server over a secure transport
but isn't.

This patch disables automatical redirection following. The driver reports
an error if the server tries to redirect.

  function and do error handling there, disable automatical redirection
  following for curl
