Make CopyMem() and SetMem() be EFIAPI

For wildly unknown reasons, EFI Boot Services includes CopyMem() and
SetMem() functions, and they are marked as EFIAPI functions.

This patch marks gnu-efi's CopyMem() and SetMem() as EFIAPI functions,
and makes their exposed API match the misguided nonsense in the EFI
spec, so that they can be used there in a test environment.

This adds 'set -e' to all of those, so they'll propagate back up.

Make ELF constructors and destructors work

This makes setup and teardown functions defined with

Make ELF constructors and destructors work

This makes setup and teardown functions defined with
__attribute__((__constructor__) and __attribute__((__destructor__)) work
in normal circumstances in EFI binaries.

A couple of notes:
- it implements both the old-style .ctors/.dtors methods and the newer
style .init_array/.fini_array ELF constructor and destructor arrays,
processed in the order:
.init_array[]
.ctors[]
efi_main()
.dtors[]
.fini_array[]
- Destructors will only be called if efi_main() exits using "return";
any call to Exit() will still longjmp() past them.
- InitializeLib() has already been called before constructors run, so
they don't need to call it (and neither does anything else.) For
compatibility, it has been altered so calling it more than once is
safe.
- No attempt is made to handle any constructor or destructor with a
prototype other than "void func(void);", but note that InitializeLib
has been called, so LibImageHandle, ST, BS, and RT are set.
- The init_array/ctor/dtor/fini_array lists aren't the using the GNU
"CONSTRUCTOR" output section command, so they don't start with a size.
- The lists are individually sorted during the link stage via
SORT_BY_NAME() in the linker script.
- The default (empty) init_array/ctor/dtor/fini_array lists are padded
out to 8-byte alignment with ".p2align 3, 0", and each list always has
at least one ".long 0" at the end of it (even if it's completely
empty). As a result, they can have NULLs that need to be skipped.
The sections they're in are mergeable, so the NULLs don't have to be
exclusively at the end.
- The ia64 and mips64el arches have not been tested.

riscv: Update SPDX license identifiers

The whole gnu-efi project is licensed under BSD license, see [1].
However some of the RISC-V codes have conflict license identifiers:

- Some mention GPL-2.0+ in the SPDX license part, but the long license
header indicates it's actually BSD and GPL-2.0+ dual-licensed
- Some mention GPL-2.0+ in the SPDX license part only
- Some do not have any license indication

To have a matching license with the whole project, this commit updates
all RISC-V codes to have the correct SPDX license identifiers
(GPL-2.0+ or BSD dual-license).

Let's suppress the warnings in assembly files by adding non-executables
stack markings. This fixes at least systemd build which uses '-Wl,--fatal-warnings':
