2022-05-11Clean up ill-advised or unusual header guardsMarkus Armbruster
Leading underscores are ill-advised because such identifiers are reserved. Trailing underscores are merely ugly. Strip both. Our header guards commonly end in _H. Normalize the exceptions. Macros should be ALL_CAPS. Normalize the exception. Done with scripts/clean-header-guards.pl. include/hw/xen/interface/ and tools/virtiofsd/ left alone, because these were imported from Xen and libfuse respectively.

2022-05-11Clean up header guards that don't match their file nameMarkus Armbruster
Header guard symbols should match their file name to make guard collisions less likely. Cleaned up with scripts/clean-header-guards.pl, followed by some renaming of new guard symbols picked by the script to better ones.

2022-02-26bsd-user: introduce target.hWarner Losh
Create target.h. This file is intended to be simple and describe basic things about the architecture. If something is a basic feature of the architecture, it belongs here. Should we need something that's per-BSD there will be a target-os.h that will live in the per-bsd directories. Define regpairs_aligned to reflect whether or not registers are 'paired' for 64-bit arguments or not. This will be false for all 64-bit targets, and will be true on those architectures that pair (currently just armv7 and powerpc on FreeBSD 14.x).

This doesn't build on openbsd at the moment, and this could should arguably be in bsd-user/*bsd/i386 somewhere. Until we refactor to support OpenBSD/NetBSD again, drop it here.

2021-09-10bsd-user: pull in target_arch_thread.h update target_arch_elf.hWarner Losh
Update target_arch_elf.h to remove thread_init. Move its contents to target_arch_thread.h and rename to target_thread_init(). Update elfload.c to call it. Create thread_os_thread.h to hold the os specific parts of the thread and threat manipulation routines. Currently, it just includes target_arch_thread.h. target_arch_thread.h contains the at the moment unused target_thread_set_upcall which will be used in the future when creating actual thread (i386 has this stubbed, but other architectures in the bsd-user tree have real ones). FreeBSD doesn't do AT_HWCAP, so remove that code. Linux does, and this code came from there. These changes are all interrelated and could be brokend down, but seem to represent a reviewable changeset since most of the change is boiler plate.
