9bb746d819 spl: Avoid checking for Ctrl-C in SPL with print_buffer()
We don't have a console in SPL so it doesn't make sense to check for
Ctrl-C when printing a memory dump. Skip this so that print_buffer() can
be used in SPL.

3545c66143 efi_loader: SetVariable() deleting variables
APPEND_WRITE with data length zero is allowable according to the UEFI
specification.

The EDK2 interpretation of no access attributes is attributes = 0. As
the UEFI specification is vague in this respect let's stick to EDK2 here.

23ad52fff4 efi_loader: device_path: support Sandbox's "host" devices
Sandbox's "host" devices are currently described as UCLASS_ROOT udevice
with DEV_IF_HOST block device. As the current implementation of
efi_device_path doesn't support such a type, any "host" device
on sandbox cannot be seen as a distinct object.

For example,
  => host bind 0 /foo/disk.img

  => efi devices
  Scanning disk host0...
  Found 1 disks
  Device           Device Path
  ================ ====================
  0000000015c19970 /VenHw(e61d73b9-a384-4acc-aeab-82e828f3628b)
  0000000015c19d70 /VenHw(e61d73b9-a384-4acc-aeab-82e828f3628b)

  => efi dh
  Handle           Protocols
  ================ ====================
  0000000015c19970 Device Path, Device Path To Text, Device Path Utilities, Unicode Collation 2, HII String, HII Database, HII Config Routing
  0000000015c19ba0 Driver Binding
  0000000015c19c10 Simple Text Output
  0000000015c19c80 Simple Text Input, Simple Text Input Ex
  0000000015c19d70 Block IO, Device Path, Simple File System

As you can see here, efi_root (0x0000000015c19970) and host0 device
(0x0000000015c19d70) have the same representation of device path.

This is not only inconvenient, but also confusing since two different
efi objects are associated with the same device path and
efi_dp_find_obj() will possibly return a wrong result.

Solution:
Each "host" device should be given an additional device path node
of "vendor device path" to make it distinguishable.

83a74ad143 efi_loader: correct reading of directories
EFI_FILE_PROTOCOL.Read() is used both to read files and directories.

When reaching the end of a directory we always have to return buffer size
zero irrespective of the incoming buffer size. (The described scenario for
a Shim quirk cannot arise because every directory has at least '.' and '..'
as entries.)

Even when the buffer_size is too small multiple times we have to keep a
reference to our last read directory entry.

When we return to the start of the directory via SetPosition() we must
remove the reference to a previously kept directory entry.
