Unified function naming scheme:
- 'lookup' functions query the ESX or vCenter for information
- 'get' functions return information from a local object

* src/esx/esx_driver.c, src/esx/esx_vi.[ch]: unify function naming

In order to register a new virtual machine the ESX driver needs to upload
a VMX file to a datastore. Try to put this file beside the main VMDK file
of the virtual machine. Change the disk selection for datastore detection
to choose the first file-based harddisk instead of just the first disk.
The first disk may be a CDROM disk and ISO images are normaly not located
in the virtual machine's directory.

* src/esx/esx_driver.c: change disk selection for datastore detection

Implementation of tunnelled migration, using a Unix Domain Socket
on the qemu backend.  Note that this requires very new versions of
qemu (0.10.7 at least) in order to get the appropriate bugfixes.

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

* src/esx/esx_driver.c: add esxNodeGetFreeMemory(), cache IP address

* 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.
