149afbf3ba Fix 64-bit syscall argument fetching in 32-bit Linux syscall handlers. 
The Linux32 system call argument fetcher places each argument (passed in
registers in the Linux x86 system call convention) into an entry in the
generic system call args array.  Each member of this array is 8 bytes
wide, so this approach is broken for system calls that take off_t
arguments.

Fix the problem by splitting l_loff_t arguments in the 32-bit system
call descriptions, the same as we do for FreeBSD32.  Change entry points
to handle this using the PAIR32TO64 macro.

Move linux_ftruncate64() into compat/linux.

6469bdcdb6 Move most of the contents of opt_compat.h to opt_global.h. 
opt_compat.h is mentioned in nearly 180 files. In-progress network
driver compabibility improvements may add over 100 more so this is
closer to "just about everywhere" than "only some files" per the
guidance in sys/conf/options.

Keep COMPAT_LINUX32 in opt_compat.h as it is confined to a subset of
sys/compat/linux/*.c.  A fake _COMPAT_LINUX option ensure opt_compat.h
is created on all architectures.

Move COMPAT_LINUXKPI to opt_dontuse.h as it is only used to control the
set of compiled files.
