Extend and cleanup the VMX to domain XML mapping. Add the domain XML to
VMX mapping functions.

  to distinguish between i686 and x86_64, make SCSI virtualDev VMX entry
  optional as it should be, map the VMX networkName entry to the domain XML
  interface bridge name, add basic mapping for serial devices in pipe mode,
  add several esxVMX_Format*() functions

This enables the auth callback to automatically distinguish between
requests for ESX host and vCenter credentials.

* src/esx/esx_util.[ch]: set challenge for auth callback to hostname

* src/esx/esx_driver.c: add esxNodeGetFreeMemory(), cache IP address
* src/esx/esx_vi.[ch]: refactor resource pool query into esxVI_GetResourcePool()
* src/esx/esx_vi_types.[ch]: bind VI type ResourcePoolResourceUsage

Add the virStrncpy function, which takes a dst string, source string,
the number of bytes to copy and the number of bytes available in the
dest string.  If the source string is too large to fit into the
destination string, including the \0 byte, then no data is copied and
the function returns NULL.  Otherwise, this function copies n bytes
from source into dst, including the \0, and returns a pointer to the
dst string.  This function is intended to replace all unsafe uses
of strncpy in the code base, since strncpy does *not* guarantee that
the buffer terminates with a \0.

* src/esx/esx_vmx.c: add it to the list of accepted devices when
  parsing the Ethernet section.

* src/esx/esx_driver.c: also strip (C) and (TM) from the CPU model
  strings

* src/esx/esx_driver.c: reorder some function calls to avoid potential
  virDomainPtr leaks

* src/esx/esx_util.c: let esxUtil_GetConfigUUID() report an error if
  virUUIDParse() fails

  esxGetCapabilities()

* src/esx/esx_vi.[ch]: convert esxVI_RemoteRequest_Execute() to a
  simpler esxVI_Context_Execute() version, remove esxVI_RemoteRequest
  and convert esxVI_RemoteResponse to esxVI_Response
* src/esx/esx_vi_methods.c: update and simplify callers to use
  esxVI_Context_Execute() instead of esxVI_RemoteRequest_Execute()

* src/esx/esx_vi.[ch]: use virXPathNode*() in
  esxVI_RemoteRequest_Execute() and remove
  esxVI_RemoteResponse_DeserializeXPathObject*()
* src/esx/esx_vi_methods.c: update callers to use the new syntax of
  esxVI_RemoteRequest_Execute()

  to check it in esxVI_GetVirtualMachineIdentity()
* src/esx/esx_vi.[ch]: add esxVI_GetManagedEntityStatus()
  and use it in esxVI_GetVirtualMachineIdentity()
* src/esx/esx_vi_types.[ch]: add VI type esxVI_ManagedEntityStatus

* src/esx/esx_driver.c: handle spaces in VMX file path and use a
  virBuffer to encode spaces correctly in the resulting URL
* src/esx/esx_vi.c: include the URL in the error message in case
  of a download error

* src/esx/esx_vi.c (esxVI_Enumeration_Deserialize): Fix
reversed goto and result=-1 statements.

* src/esx/esx_util.c: esxUtil_ParseQuery() warns if a known query
  parameter should be ignored due to the corresponding char/int pointer
  being NULL, instead of silently ignoring it. Fix the control flow.

* src/esx/esx_vmx.c: add an extra type of addressType beside 'static'
  and 'generated', 'vpx' indicates that the MAC address was generated
  by a vCenter.

While trying to remove uses of unsafe strncpy in the tree, I came
across a couple of usages in the ESX driver.  To my eyes, the snprintf
replacements do the same thing in less code, and are also safer.
