    libxl: s/pcidev/pci and remove DEFINE_DEVICE_TYPE_STRUCT_X
    
    The seemingly arbitrary use of 'pci' and 'pcidev' in the code in libxl_pci.c
    is confusing and also compromises use of some macros used for other device
    types. Indeed it seems that DEFINE_DEVICE_TYPE_STRUCT_X exists solely 
because
    of this duality.
    
    This patch purges use of 'pcidev' from the libxl internal code, but
    unfortunately the 'pcidevs' and 'num_pcidevs' fields in 
'libxl_domain_config'
    are part of the API and need to be retained to avoid breaking callers,
    particularly libvirt.
    
    DEFINE_DEVICE_TYPE_STRUCT_X is still removed to avoid the special case in
    libxl_pci.c but DEFINE_DEVICE_TYPE_STRUCT is given an extra 'array' argument
    which is used to identify the fields in 'libxl_domain_config' relating to
    the device type.
    
    NOTE: Some of the more gross formatting errors (such as lack of spaces after
          keywords) that came into context have been fixed in libxl_pci.c.
