[PATCH v3 0/4] x86: build adjustments

[Jan Beulich <jbeulich@xxxxxxxx>]

This is a in part just loosely connected set of changes in particular
aiming at further shim size binary reduction.

Review feedback for v2 addressed for 1 and 2; 3 and 4 unchanged. One
patch was dropped.

1: x86/EFI: sanitize build logic
2: x86: don't build with EFI support in shim-exclusive mode
3: bitmap: move to/from xenctl_bitmap conversion helpers
4: x86: don't include domctl and alike in shim-exclusive builds
