Add /* unprivileged */ to a variety of tapset embedded-c functions,
together with uid-assertion-checking code as needed. This is only
an initial set, and may need to grow or shrink after further testing.
Prototyped-By: Dave Brolley <brolley@redhat.com>
* runtime/runtime.h (is_myproc, assert_is_myproc): New macros.
* runtime/addr-map.c (lookup_bad_addr): Reject if !is_myproc
in unprivileged mode.
* runtime/print.c (_stp_print_kernel_info): Add unprivileged
mode info.
* tapset/DEVGUIDE: Document /* pure */ and /* unprivileged */.
* tapset/*.stp: Add /* unprivileged */ here and there, in
questionable cases along with an assert_is_myproc().

* tapset/utrace.stp: Cast the return value of
syscall_get_return_value() to an unsigned long to avoid sign
extension.

* buildrun.cxx (compile_pass): Compile autoconf test for
<asm/syscall.h>.
* runtime/autoconf-asm-syscall.c: New "autoconf" test the presence
of <asm/syscall.h>.
* runtime/syscall.h: If <asm/syscall.h> exists, use it.
Otherwise, use our private copy of the functions for each
architecture.
(syscall_get_nr): Renamed from __stp_user_syscall_nr().
(syscall_get_return_value): Renamed from
__stp_user_syscall_return_value().
(syscall_get_arguments): Renamed from __stp_user_syscall_arg().
* runtime/task_finder.c
(__stp_utrace_task_finder_target_syscall_exit): Uses new syscall.h
functions.
* tapset/utrace.stp: Ditto.
