Vladimir Olovyannikov b5bd3ed648 MdeModulePkg FvSimpleFileSystemDxe: Fix memory leak in Read function
FvSimpleFileSystem on read always allocates a FileBuffer, and never frees
it. This causes memory leaks. It is especially bad for reading scripts
line-by-line. In some cases memory leak can exceed 1GB.

Jian J Wang 469293f8ee MdeModulePkg: Fix misuses of AllocateCopyPool
AllocateCopyPool(AllocationSize, *Buffer) will copy "AllocationSize" bytes of
memory from old "Buffer" to new allocated one. If "AllocationSize" is bigger
than size of "Buffer", heap memory overflow occurs during copy.

One solution is to allocate pool first then copy the necessary bytes to new
memory. Another is using ReallocatePool instead if old buffer will be freed
on spot.

Olivier Martin 1ca40fa9d9 MdeModulePkg/FvSimpleFileSystemDxe: Support file opening with no '.efi'
FvSimpleFileSystem adds '.efi' to the EFI application and drivers
filenames even through this extension is not present in the real
filename of the EFI module.

In the current behaviour, it would not be possible to open an EFI
application using FvSimpleFileSystem if the extension has been omitted
in the given filename.
It can be create some confusion if someone wants to try to
open a file with the real application name (eg: 'Shell').

This patch adds support to try again to look for the file with the
extension if it had failed to find it without the extension.
