This more clearly differentiates system call arguments from integer

between system call arguments (syscallarg_t) and integer register values

truss: split counting of syscalls and syscall calling convention

This change is a refactoring cleanup to improve support for compat32
syscalls (and compat64 on CHERI systems). Each process ABI now has it's
own struct sycall instead of using one global list. The list of all
syscalls is replaced with a list of seen syscalls. Looking up the syscall
argument passing convention now interates over the fixed-size array instead
of using a link-list that's populated on startup so we no longer need the
init_syscall() function.
The actual functional changes are in D27625.

Use PT_GET_SC_ARGS and PT_GET_SC_RET in truss.

This removes all of the architecture-specific functions from truss.

A per-ABI structure is still needed to map syscall numbers to names
and FreeBSD errno values to ABI error values as well as hold syscall
counters. However, the linker set of ABI structures is now replaced
with a simple table mapping ABI names to structures. This approach
permits sharing the same ABI structure among separate names such as
i386 a.out and ELF binaries as well as ELF v1 vs ELF v2 for powerpc64.

A few differences are visible due to using PT_GET_SC_RET to fetch the
error value of a system call. Note that ktrace/kdump have had the
"new" behaviors for a long time already:
- System calls that return with EJUSTRETURN or ERESTART will now be
noticed and logged as such. Previously sigreturn (which uses
EJUSTRETURN) would report whatever random value was in the register
holding errno from the previous system call for example. Now it
reports EJUSTRETURN.
- System calls that return errno as their error value such as
posix_fallocate() and posix_fadvise() now report non-zero return
values as errors instead of success with a non-zero return value.
