Use clamping to more easily normalize input values
The kernel has min/max/clamp macros to make range comparisons easier.
Clamp is a newer invention, but we can define it for older kernels in
terms of min and max.

Don't pass client-only options to the server.
Also correct parsing of the --server option.

Rework identification of probes allowed for unprivileged users.
- Bind unprivileged permission at probe registration time.
- Remove check_unprivileged filter from derived_probe_builder
and its children.
- Add test suites for unprivilegedok and unprivilegedko.

PR11256: harden --unprivileged mode
* tapsets-mark.cxx, tapsets.cxx: Don't even publish probe point families that are
inappropriate for use in --unprivileged mode.
(dwarf_derived_probe_*unprivileged*): Remove, to default to blanket no-permission
rather than emit_process_owner_permission mode.
* testsuite/semko/fortyeight.stp: New test.

Support building against elfutils < 0.142 again.
* dwflpp.cxx (get_cfa_ops): Guard new cfi related code and variables.
commit be13343b3a72749c2881d418f2e7eeba0387f0c7
Author: Mark Wielaard <mjw@redhat.com>
Date: Tue Feb 2 13:47:19 2010 +0100
Make sure cfa_ops are always retrieved through dwfl global address.
dwflpp::translate_location() works on the dw address space, but
get_cfa_ops() starts out with dwfl calls (only dwarf_cfi_addrframe()
needs to be adjusted for bias).
* dwflpp.cxx (translate_location): Pass pc plus module bias through to
get_cfa_ops.
(get_cfa_ops): Adjust for bias when calling dwarf_cfi_addrframe(),
add frame start/end address when found if verbose logging.
* testsuite/systemtap.exelib/lib.stp: Add $foo and $bar variables to
process.function probes.
* testsuite/systemtap.exelib/libmarkunamestack.stp: Likewise.
* testsuite/systemtap.exelib/lib.tcl: Expect correct values for
process.function probe variables.
* testsuite/systemtap.exelib/libmarkunamestack.tcl: Likewise.

PR11173 Markers get a bad address in prelinked libraries.
Our literal_addr_to_sym_addr() function was just wrong. To compensate for
raw addresses read from elf (either given by the user or through a mark
transformation) we need to know what the elf_bias is (as returned by
dwfl_module_getelf) before feeding them to any libdwfl functions.
* tapsets.cxx (query_module_dwarf): Always add elf_bias to raw function or
statement addresses before calling query_addr().
(query_addr): Don't call literal_addr_to_sym_addr().
* dwflpp.h (literal_addr_to_sym_addr): Removed.
* dwflpp.cxx (literal_addr_to_sym_addr): Likewise.

Fixed BZ559643 by doing 'spawn;expect;wait' instead of 'spawn;wait;expect'.
* testsuite/systemtap.base/labels.exp: Corrected order of
'spawn;expect;wait' calls. Added 'wait' calls when needed. Also,
doesn't run the "labels exe .label" test if uprobes isn't supported.

rhbz#563114 Make syscall.pipe sys32_pipe probe alias optional on x86_64.
Some distributions might have backported the pipe fd leak patch and removed
the sys32_pipe kernel function even before 2.6.32. So make the probe alias
optional instead of relying on a version check.
* tapset/x86_64/syscalls.stp (syscall.pipe): Make alias optional.
(syscall.pipe.return): Likewise.

rhbz 560890: preserve -L/-l variable ordering
Switch to list<string> from set<string> for collecting
available $var lists. Use O(N**2) list-uniqueifier
that preserves initial ordering.

PR11234: Rewrite __get_argv without embedded-C
We now implement __get_argv's string building in pure stap script.
Also, every argument is now quoted, which is different than before, but
it's much more robust about handling special characters.
