Ruiyu Ni 1e57188216 EmulatorPkg: IoThunk->Close() is called too early, may causing hang
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1121

To produce a EFI_BLOCK_IO_PROTOCOL instance in Emulator platform,
EmulatorPkg defines the EMU_IO_THUNK_PROTOCOL. OS dependent layer
needs to produce this protocol implementation and a generic OS
independent layer consumes this protocol to produce
EFI_BLOCK_IO_PROTOCOL.

EMU_IO_THUNK_PROTOCOL can also be used to abstract the OS dependent
IO operation for other UEFI protocols, e.g.: GOP, SimpleFileSystem
and etc.

It contains two interfaces Open() and Close(). Open() creates the
specific IO instances, e.g. for Block IO access, File System access,
Screen access, etc. Close() destroys the specific IO instances.

Later on the Emulator generic module (e.g.: EmuBlockIoDxe) calls
Open() to create the IO instance in DriverBindingStart() and calls
Close() in DriverBindingStop().
But today's implementation of DriverBindingStop() contains a bug
that it calls Close() before uninstalling the EFI_BLOCK_IO_PROTOCOL.

It's a mistake in code. Take EFI_BLOCK_IO for example,
the uninstallation may cause the upper layer driver that consumes
EFI_BLOCK_IO call BlockIo.Reset(), which consequently calls
EmuBlockIo.Reset(). But the EmuBlockIo instance is already destroyed
by Close() that happens before uninstallation.

So a proper implementation is to call Close() after uninstallation
succeeds.

Ruiyu Ni 3da7b0639f EmulatorPkg/EmuFileSystem: Fix a bug that causes Close() assertion
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1117

The root cause is when a file is opened through File.Open(), the
private data for the File is not allocated, so when later
when File.Close() is called, the signature check in CR() causes
the assertion.

The private data for the File is allocated properly when the file
is opened from FS.OpenVolume().

The patch also fixes a minor issue that wrongly assigns
revision number to File.

Paulo Alcantara dda74d6d62 EmulatorPkg/EmuSimpleFileSystemDxe: Fix incorrect return values upon allocation failure
In EmuSimpleFileSystemOpenVolume() function - in case an allocation failed
with AllocatePool() - EFI_UNSUPPORTED was being returned instead of
EFI_OUT_OF_RESOURCES, which is incorrect.

Even worse, in EmuSimpleFileSystemDriverBindingStart(), an unitiliasied
variable (Status) will be returned in case of an allocation failure with
AllocateZeroPool().

This patch fixes both issues by correctly returning EFI_OUT_OF_RESOURCES.
