This patch series is to:
(1) Update VfrCompiler to parse UNION type, bit field in data structure.
(2) Update HiiDatabase and SetupBrowser to handle questions with Bit VarStore.
(3) Add sample questions with bit/union VarStore in DriverSample.

https://bugzilla.tianocore.org/show_bug.cgi?id=545

Enhance VfrCompiler to parse following case:
1. EFI/Buffer VarStore can contain bit fields in their structure.
2. For question Oneof/Checkbox/numeric, their storage can be
   bit fields of an EFI VarStore/Buffer VarStore.

For oneof/numeric/checkbox, their storage may be bit field.
When generating <ConfigAltResp> string to get default value
for these questions, we need to parse the Ifr data to get
the bit Varstore info,and then generating the correct
<ConfigAltResp> string.

  To: edk2-devel; +Cc: Eric Dong, Liming Gao

https://bugzilla.tianocore.org/show_bug.cgi?id=545

For oneof/numeric/CheckBox(storage can be Bit VarStore)
If the question value can be updated and shown correctly
in UI page, we need do enhancements in following cases:
1. Parse the Ifr data to get the bit VarStore info correctly.
2. Set/get value to/from bit VarStore correctly.

Subject: [patch 0/6] Support bitfield and union type in vfr

This patch series is to:
(1) Update VfrCompiler to parse UNION type, bit field in data structure.
(2) Update HiiDatabase and SetupBrowser to handle questions with Bit VarStore.
(3) Add sample questions with bit/union VarStore in DriverSample.
