Subject: [PATCH 1/2] efibind: Fix usage of efi headers from C++ code
* __STDC_VERSION__ is undefined when headers are called from C++
code resulting in not using stdint.h and efibind.h
"making a guess" on what they are. extern "C" will not define
__STDC_VERSION__.
* Always leverage stdint.h on C++.
* Honestly, gnu-efi should always use stdint.h, or find a better
way to detect it. (or platforms without it need to catch up to 2007)

Subject: [PATCH] Make ELF constructors and destructors work.
Subject: [PATCH 01/18] 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 ia64 and mips64el arches have not been tested.
