Apply consistent naming scheme for hostlib functions.

The chromeos-installer uses several functions from the vboot_reference
userspace library, but the names of those functions are inconsistent:

  IsZero
  MapFile
  VbGetSystemPropertyString
  cgpt_add
  cgpt_boot
  cgpt_create
  cgpt_get_boot_partition_number
  cgpt_get_num_non_empty_partitions
  cgpt_get_partition_details
  cgpt_prioritize
  cgpt_set_attributes
  find_kernel_config

The Google C++ style guide says types and functions should use CamelCase,
while variables use lower_case_with_underscores.

Kernel style (which vboot_reference tries to be more-or-less compatible
with) uses lower_case_with_underscores for everything, but that really only
has to apply to firmware stuff. For userspace, we can use the Google style.
