2022-05-11Clean up ill-advised or unusual header guardsMarkus Armbruster8-24/+27
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.

2022-02-26bsd-user/bsd-file.h: Implementation details for the filesystem callsWarner Losh1-0/+2
An include file that pulls in all the definitions needed for the file related system calls. This also includes the host definitions to implement the system calls and some helper routines to lock/unlock different aspects of the system call arguments.

2022-02-26bsd-user/freebsd/os-syscall.c: Add get_errno and host_to_target_errnoWarner Losh1-1/+22
Add the helper functions get_errno and host_to_target_errno. get_errno returns either the system call results, or the -errno when system call indicates failure by returning -1. Host_to_target_errno returns errno (since on FreeBSD they are the same on all architectures) along with a comment about why it's the identity.

2022-02-26bsd-user/freebsd/os-syscall.c: Move syscall processing hereWarner Losh1-0/+69
While there is some commonality between *BSD syscall processing, there's a number of differences and the system call numbers and ABIs have been independent since the late 90s. Move FreeBSD's proessing here and delete it. The upstream implementation is somewhat different than the current implementation. It will be much easier to upstream these from scratch, justifying the final result, rather than working out the diffs and justifying the changes. Also tweak a comment to qemu standard form.

2022-01-07bsd-user/freebsd: Create common target_os_ucontext.h fileWarner Losh2-3/+35
FreeBSD has a MI ucontext structure that contains the MD mcontext machine state and other things that are machine independent. Create an include file for all the ucontext stuff. It needs to be included in the arch specific files after target_mcontext is defined. This is largely copied from sys/_ucontext.h with the comments about layout removed because we don't support ancient FreeBSD binaries.

2021-09-10bsd-user: pull in target_arch_thread.h update target_arch_elf.hWarner Losh1-0/+25
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.
