[efi] Provide access to files stored on EFI filesystems
Provide access to local files via the "file://" URI scheme. There are
three syntaxes:
- An opaque URI with a relative path (e.g. "file:script.ipxe").
This will be interpreted as a path relative to the iPXE binary.
- A hierarchical URI with a non-network absolute path
(e.g. "file:/boot/script.ipxe"). This will be interpreted as a
path relative to the root of the filesystem from which the iPXE
binary was loaded.
- A hierarchical URI with a network path in which the authority is a
volume label (e.g. "file://bootdisk/script.ipxe"). This will be
interpreted as a path relative to the root of the filesystem with
the specified volume label.
Note that the potentially desirable shell mappings (e.g. "fs0:" and
"blk0:") are concepts internal to the UEFI shell binary, and do not
seem to be exposed in any way to external executables. The old
EFI_SHELL_PROTOCOL (which did provide access to these mappings) is no
longer installed by current versions of the UEFI shell.
