* stime.h: prototype for scm_times.

* stime.c (scm_times): new procedure.
* ioext.c (scm_fseek): if the first argument is a file descriptor
call lseek.
(scm_ftell): if the first argument is a file descriptor call lseek
(sic).
* filesys.h: prototypes for scm_open_fdes, scm_fsync.
* filesys.c (scm_chmod): if the first argument is a file descriptor,
call fchmod.
(scm_chown): if the first argument is a port or file descriptor,
call fchown.
(scm_truncate_file): new procedure.
Add DEFER/ALLOW INTS to a few other procedures.
(scm_fsync): new procedure.
(scm_open_fdes): new procedure.
(scm_open): use scm_open_fdes.  If mode isn't specified, 666 will
now be used.
(scm_fcntl): the first argument can now be a file descriptor.  The
third argument is now optional.

* posix.c (scm_execl, scm_execlp): make the filename argument
compulsory, since omitting it causes SEGV.
(scm_sync): return unspecified instead of #f.
(scm_execle): new procedure.
(environ_list_to_c): new procedure.
(scm_environ): use environ_list_to_c.  disable interrupts.
(scm_convert_exec_args): take pos and subr arguments and
improve error checking.

* boot-9.scm: define tms accessors: clock, utime, stime, cutime,
cstime.

** the first argument to chmod, fcntl, ftell and fseek can now be a

** truncate-file OBJ SIZE
Truncates the file referred to by OBJ to at most SIZE bytes. OBJ
can be a string containing a file name or an integer file
descriptor or port open for output on the file. The underlying
system calls are `truncate' and `ftruncate'.
The return value is unspecified.

size. Procedures e.g., *Note open-file: File Ports, which accept a
mode string allow `0' to be added to request an unbuffered port.
** primitive-exit [STATUS]
Terminates the current process without unwinding the Scheme stack.
This would usually be used after a fork.
** fsync PORT/FD
Copies any unwritten data for the specified output file descriptor
to disk. If PORT/FD is a port, its buffer is flushed before the
underlying file descriptor is fsync'd. The return value is
unspecified.
** open-fdes PATH FLAGS [MODES]
Similar to `open' but returns a file descriptor instead of a port.
** procedure: execle PATH ENV [ARG] ...
Similar to `execl', but the environment of the new process is
specified by ENV, which must be a list of strings as returned by
the `environ' procedure.
This procedure is currently implemented using the `execve' system
call, but we call it `execle' because of its Scheme calling
interface.
** procedure: primitive-exit [STATUS]
Terminate the current process without unwinding the Scheme stack.
This is would typically be useful after a fork. The exit status
is STATUS if supplied, otherwise zero.
** procedure: times
Returns an object with information about real and processor time.
The following procedures accept such an object as an argument and
return a selected component:
`tms:clock'
The current real time, expressed as time units relative to an
arbitrary base.
`tms:utime'
The CPU time units used by the calling process.
`tms:stime'
The CPU time units used by the system on behalf of the
calling process.
`tms:cutime'
The CPU time units used by terminated child processes of the
calling process, whose status has been collected (e.g., using
`waitpid').
`tms:cstime'
Similarly, the CPU times units used by the system on behalf of
terminated child processes.
