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.

847689129c esx: Rework datastore path parsing and handling
Instead of splitting the path part of a datastore path into
directory and file name, keep this in one piece. An example:

  "[datastore] directory/file"

was split into this before:

  datastoreName = "datastore"
  directoryName = "directory"
  fileName = "file"

Now it's split into this:

  datastoreName = "datastore"
  directoryName = "directory"
  directoryAndFileName = "directory/file"

This simplifies code using esxUtil_ParseDatastorePath, because
directoryAndFileName is used more often than fileName. Also the
old approach expected the datastore path to reference an actual
file, but this isn't always correct, especially when listing
volumes. In that case esxUtil_ParseDatastorePath is used to parse
a path that references a directory. This fails for a vpx://
connection because the vCenter returns directory paths with a
trailing '/'. The new approach is robust against this and the
actual decision if the datastore path should reference a file or
a directory is up to the caller of esxUtil_ParseDatastorePath.

Update the tests accordingly.

e1bd99ab7e esx: Fix esxVI_BuildSelectSet's invalid argument check
The check was altered in 8c48743b97
and got too strict, I've no clue how that snuck in. This check
makes every try to open a connection using the ESX driver fail
with an invalid argument error.

Revert the change to the check and add a comment to prevent future
mistakes with this check.

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.

f688faceac esx: Fix memory leak when looking up an non-existing domain by name

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.

041aac8648 esx: Simplify goto usage
Eliminate almost all backward jumps by replacing this common pattern:

int
some_random_function(void)
{
    int result = 0;
    ...

  cleanup:
    <unconditional cleanup code>
    return result;

  failure:
    <cleanup code in case of an error>
    result = -1;
    goto cleanup
}

with this simpler pattern:

int
some_random_function(void)
{
    int result = -1;
    ...
    result = 0;

  cleanup:
    if (result < 0) {
        <cleanup code in case of an error>
    }

    <unconditional cleanup code>
    return result;
}

Add a bool success variable in functions that don't have a int result
that can be used for the new pattern.

Also remove some unnecessary memsets in error paths.

b1fab0c21c esx: Don't treat an empty root snapshot list as error
An empty root snapshot list was considered as error condition. Creating a
new snapshot would fail if the domain didn't have snapshots yet, because
the snapshot-create function tries to lookup the list of existing snapshots
in order to verify that the snapshot name is unique. This fails if the
domain doesn't have snapshots yet.

Removing the NULL check from esxVI_LookupRootSnapshotTreeList fixes this.

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.
