ed d29789315a Properly format pointer size independent CloudABI system calls.
CloudABI has approximately 50 system calls that do not depend on the
pointer size of the system. As the ABI is pretty compact, it takes
little effort to each truss(8) the formatting rules for these system
calls. Start off by formatting pointer size independent system calls.

Changes:

- Make it possible to include the CloudABI system call definitions in
  FreeBSD userspace builds. Add ${root}/sys to the truss(8) Makefile so
  we can pull in <compat/cloudabi/cloudabi_syscalldefs.h>.
- Refactoring: patch up amd64-cloudabi64.c to use the CLOUDABI_*
  constants instead of rolling our own table.
- Add table entries for all of the system calls.
- Add new generic formatting types (UInt, IntArray) that we'll be using
  to format unsigned integers and arrays of integers.
- Add CloudABI specific formatting types.

*
* System call arguments come in several flavours:
* Hex -- values that should be printed in hex (addresses)
* Octal -- Same as above, but octal
* Int -- normal integer values (file descriptors, for example)
* LongHex -- long value that should be printed in hex
* Name -- pointer to a NULL-terminated string.
* BinString -- pointer to an array of chars, printed via strvisx().
* Ptr -- pointer to some unspecified structure. Just print as hex for now.
* Stat -- a pointer to a stat buffer. Prints a couple fields.
* StatFs -- a pointer to a statfs buffer. Prints a few fields.
* Ioctl -- an ioctl command. Woefully limited.
* Quad -- a double-word value. e.g., lseek(int, offset_t, int)
* Signal -- a signal number. Prints the signal name (SIGxxx)
* Sockaddr -- a pointer to a struct sockaddr. Prints symbolic AF, and IP:Port
* StringArray -- a pointer to an array of string pointers.
* Timespec -- a pointer to a struct timespec. Prints both elements.
* Timeval -- a pointer to a struct timeval. Prints both elements.
* Timeval2 -- a pointer to two struct timevals. Prints both elements of both.
* Itimerval -- a pointer to a struct itimerval. Prints all elements.
* Pollfd -- a pointer to an array of struct pollfd. Prints .fd and .events.
* Fd_set -- a pointer to an array of fd_set. Prints the fds that are set.
* Sigaction -- a pointer to a struct sigaction. Prints all elements.
* Sigset -- a pointer to a sigset_t. Prints the signals that are set.
* Sigprocmask -- the first argument to sigprocmask(). Prints the name.
* Kevent -- a pointer to an array of struct kevents. Prints all elements.
* Pathconf -- the 2nd argument of pathconf().
* Utrace -- utrace(2) buffer.
*
* In addition, the pointer types (String, Ptr) may have OUT masked in --
* this means that the data is set on *return* from the system call -- or
* IN (meaning that the data is passed *into* the system call).
