c7zero 40a8ae5d6e Support of native API mode (#59) ...

* Native API mode support

With this change CHIPSEC can operate in two modes:
1. Using CHIPSEC own kernel driver (default mode, --no_driver option was
not specified)
2. Native OS API mode when helper API can be implemented via native OS
API (--no_driver command-line option was specified)

At the moment, most of the helper API are not implemented in native
mode, except get_ACPI_table in Windows helper.

Helpers, HAL components or modules can use use_native_api() function of
the helper to determine which mode to use. Currently, it directly maps
to --no_driver option. Modules can call this function in is_supported()
if they can only run in either of the modes.

Additional changes:
1. Cleaned up destroy/delete/stop mess in the helpers. Removed destroy()
from the helpers
2. Fixed --exists mode when CHIPSEC works with kernel driver which has
already been loaded.

* Fixed missing driver_exists in start() in Linux and EFI helpers

* Updated mock_helper

* use_native_api

- Added use_native_api to cs
- Added use_native_api routing to OSHelper
- Refactred Linux helper to have "native" functions (physical_mem,
pci_reg, mmio, variables)

* Bugfixes

1. Chaged ACPI HAL to use read_physical_mem in native API mode as well
(/dev/mem) and only attempt get_ACPI_table if helper doesn't implement
native_read_physical_mem
2. Fixed set_EFI_variable in Linux helper
3. Fixed exceptions in OSHelper

* Added raising exceptions in native_read/write_physical_mem in win32helper

* Fixed incorrect change

* UEFI variable changes

- Fixed EFIVAR/VAR_set_EFI_variable return status inconsistency
- Added EFI status codes
- clenup
