Peter Maydell 005eb2ae1f linux-user: Fix target_semid_ds structure definition
The target_semid_ds structure is not correct for all
architectures: the padding fields should only exist for:
 * 32-bit ABIs
 * x86

It is also misnamed, since it is following the kernel
semid64_ds structure (QEMU doesn't support the legacy
semid_ds structure at all). Rename the struct, provide
a correct generic definition and allow the oddball x86
architecture to provide its own version.

This fixes broken SYSV semaphores for all our 64-bit
architectures except x86 and ppc.

Markus Armbruster 3500385697 linux-user: Clean up target_structs.h header guards
These headers all use TARGET_STRUCTS_H as header guard symbol.  Reuse
of the same guard symbol in multiple headers is okay as long as they
cannot be included together.

Since we can avoid guard symbol reuse easily, do so: use guard symbol
$target_TARGET_STRUCTS_H for linux-user/$target/target_structs.h.

Petar Jovanovic 55a2b1631f linux-user: create target_structs header to place ipc_perm and shmid_ds
Creating target_structs header in linux-user/$arch/ and making
target_ipc_perm and target_shmid_ds its first inhabitants.
The struct defintions may/should be further fine-tuned by arch maintainers.
