Due to the way this syscall handles siginfo_t, we only need to shift
data through the padding.
This is due to the syscall not allowing you to send siginfo_t with
si_code being positive. Which is what the kernel uses to interpret the
data if it is reinterpreting it.
The main one that we can't implement is readdir. Falls in to the same
problem space as getdents.
With this, we have the full entry tables filled out for both 64-bit and
32-bit. With some holes in the implementation, we have almost all
coverage now.
Migrates lingering instances of the old logger over to fmt where
applicable. This allows removing some of the old defines and functions.
The only remaining usages of the printf-based variant of the logger is
in Tests/LinuxSyscalls/Syscalls.cpp for the strace handling.
Needed to fix rt_sigtimedwait to use the raw syscall.
Needed to have sigtimedwait and sigtimedwait_time64 parse siginfo_t
correctly.
glibc uses this to ensure it is sending the correct signal across from
their helper thread.
Needed to correctly parse sigval and sigevent for 32-bit.
Passes my unit test for timer_create
This isn't quite a 100% clean sweep of IWYU.
There are some false positives where clang fails.
Additionally there are still a few missed in the frontend side of things
that I didn't get to
The vast majoirty of syscalls don't need anything in thread or frame.
So lets save an indirection for all those syscalls.
Most of the syscalls which do need Thread (or CTX via
Thread are in Thread.cpp or Memory.cpp
These have all been modifiy to fetch Thread from Frame
