  src/xenapi/xenapi_driver.c: Add dummy entries in driver
  table for new APIs

This matches the public API and helps to get rid of some special
case code in the remote generator.

Rename driver API functions and XDR protocol structs.

No functional change included outside of the remote generator.

gcc 4.6 warns when a variable is initialized but isn't used afterwards:

vmware/vmware_driver.c:449:18: warning: variable 'vmxPath' set but not used [-Wunused-but-set-variable]

This patch fixes these warnings. There are still 2 offending files:

- vbox_tmpl.c: the variable is used inside an #ifdef and is assigned several
  times outside of #ifdef. Fixing the warning would have required wrapping
  all the assignment inside #ifdef which hurts readability.

vbox/vbox_tmpl.c: In function 'vboxAttachDrives':
vbox/vbox_tmpl.c:3918:22: warning: variable 'accessMode' set but not used [-Wunused-but-set-variable]

- esx_vi_types.generated.c: the name implies it's generated code and I
  didn't want to dive into the code generator

esx/esx_vi_types.generated.c: In function 'esxVI_FileQueryFlags_Free':
esx/esx_vi_types.generated.c:1203:3: warning: variable 'item' set but not used [-Wunused-but-set-variable]

It is possible to set a migration speed limit when starting
migration. This new API allows the speed limit to be changed
on the fly to adjust to changing conditions

This patch introduces a new libvirt API (virDomainSetMemoryFlags) and
a flag (virDomainMemoryModFlags).

virRun gives pretty useful error output, let's not overwrite it unless there
is a good reason. Some places were providing more information about what
the commands were _attempting_ to do, however that's usually less useful from
a debugging POV than what actually happened.

VIR_ERR_OPERATION_INVALID means that the operation is not valid
for the current state of the involved object.

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.
