closures: Create temporary file with O_TMPFILE and O_CLOEXEC when available
The open_temp_exec_file_dir function can create a temporary file without
file system accessible link. If the O_TMPFILE flag is not defined (old
Linux kernel or libc) the behavior is unchanged.
The open_temp_exec_file_name function now need a new argument "flags"
(like O_CLOEXEC) used for temporary file creation.
The O_TMPFILE flag allow temporary file creation without race condition.
This feature/fix prevent another process to access the (future)
executable file from the file system.
The O_CLOEXEC flag automatically close the temporary file for any
execve. This avoid transmitting (executable) file descriptor to a child
process.

Fix ABI on 32-bit non-Windows x86: go back to trampoline size 10
The trampoline size is part of the ABI, so it cannot change. Move the
logic from the stdcall and thiscall trampolines to the functions they
call, to reduce them both to 10 bytes.
This drops the previously added support for raw THISCALL closures on
non-Windows. (Non-raw THISCALL closures still work.)

When sizeof(size_t) != sizeof(unsigned), adding a size_t to cif->bytes

the warning.

Add support for stdcall, thiscall, and fastcall on non-Windows x86-32
Linux supports the stdcall calling convention, either via functions
explicitly declared with the stdcall attribute, or via code compiled
with -mrtd which effectively makes stdcall the default.
This introduces FFI_STDCALL, FFI_THISCALL, and FFI_FASTCALL on
non-Windows x86-32 platforms, as non-default calling conventions.

before returning FFI_BAD_ABI. However, on X86_WIN32, FFI_THISCALL

This separates the 32-bit sysv/linux/bsd code from the 64-bit linux
code, and makes it possible to link code compiled with different
options to those used to compile libffi. For example, a
-mlong-double-128 libffi can be used with -mlong-double-64 code.
Using the return value area as a place to pass parameters wasn't such
a good idea, causing a failure of cls_ulonglong.c. I didn't see this
when running the mainline gcc libffi testsuite because that version of
the test is inferior to the upstreamm libffi test.
Using NUM_FPR_ARG_REGISTERS rather than NUM_FPR_ARG_REGISTERS64 meant
that a parameter save area could be allocated before it was strictly
necessary. Wrong but harmless. Found when splitting apart ffi.c
into 32-bit and 64-bit support.

Finally, this adds _CALL_ELF == 2 support. ELFv1 objects can't be
linked with ELFv2 objects, so this is one case where preprocessor
tests in ffi.c are fine. Also, there is no need to define a new
FFI_ELFv2 or somesuch value in enum ffi_abi. FFI_LINUX64 will happily
serve both ABIs.

Andreas' 2013-02-08 change reverted some breakage for struct return
values from 2011-11-12, but in so doing reintroduced string
instructions to sysv.S that are not supported on all powerpc variants.
This patch properly copies the bounce buffer to destination in C code
rather than in asm.
I have tested this on powerpc64-linux, powerpc-linux and
powerpc-freebsd. Well, the last on powerpc-linux by lying to
configure with
CC="gcc -m32 -msvr4-struct-return -mlong-double-64" \
CXX="g++ -m32 -msvr4-struct-return -mlong-double-64" \
/src/libffi-current/configure --build=powerpc-freebsd
and then
make && make CC="gcc -m32" CXX="g++ -m32" \
RUNTESTFLAGS=--target_board=unix/-m32/-msvr4-struct-return/-mlong-double-64\
check

The powerpc64 ABIs align structs passed by value, a fact ignored by
gcc for quite some time. Since gcc now does the correct alignment,
libffi needs to follow suit. This ought to be made selectable via
a new abi value, and the #ifdefs removed from ffi.c along with many
other #ifdefs present there and in assembly. I'll do that with a
followup patch sometime.
This is a revised version of
https://sourceware.org/ml/libffi-discuss/2013/msg00162.html

The powerpc64 support opted to pass floating point values both in the
fpr area and the parameter save area, necessary when the backend
doesn't know if a function argument corresponds to the ellipsis
arguments of a variadic function. This patch adds powerpc support for
variadic functions, and changes the code to only pass fp in the ABI
mandated area. ELFv2 needs this change since the parameter save area
may not exist there.
This also fixes two faulty tests that used a non-variadic function
cast to call a variadic function, and spuriously reasoned that this is
somehow necessary for static functions..
