This reverts commit 029b59ba53d0cc42630d623b52d94cae0df62734.
When $rb_cv_prog_dtrace_g is yes on FreeBSD even if /usr/bin/dtrace
exists, it means dtrace is disabled on the system.

* configure.in (--enable-dtrace): remove ineffective "else AS_CASE ..."
because the variable $rb_cv_prog_dtrace_g is normally "yes" on
FreeBSD and the AS_CASE is not evaluated on FreeBSD.

* common.mk (vm_dump.$(OBJEXT)): remove dependency on probes.h

USE_TRAP_MASK.
* signal.c (trap_arg, trap_ensure): removed.
* signal.c (trap, sig_trap): removed pointless signal disabling.
We don't need it bacause we no longer run trap hander on signal
hander context.

* NEWS: add an item about above

* struct.c (rb_struct_each_pair): yield associated pairs so that
an unsplat argument can get both, for consistency with Hash,
OpenStruct, and etc. [ruby-dev:46533] [Bug #7382]
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37721 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* common.mk (RUBYLIB): purelib option in runruby.rb is deprecated
since r28841, so set to an empty list to get rid of a bogus path in
child processes, which caused an insecure operation exception in
test/ruby/test_encoding.rb:test_unsafe.

* configure.in: see enable_dtrace for adding libelf on FreeBSD.
* common.mk: VPATH is not needed.

This method is similart to `caller_locations' method for
specific method.
And fix to accept `level' and `n' parameters for `Thread#backtrace'
and `Thread#backtrace_locations'.
`caller' (and `caller_locations') do not return `caller' method
frame.
However, `Thread#backtrace' (and `Thread#backtrace_locations')
return `Thread#backtrace' method frame itself
if `Thread.current.backtrace' was called.
* vm_backtrace.c: ditto.
* internal.h: ditto.
* test/ruby/test_backtrace.rb: add tests.

see $(srcdir).
* common.mk (probes.dmyh): now created it on $(srcdir) always.
* win32/Makefile.sub (.SUFFIXES): removed common suffix.

RUBY_DTRACE_FUNC_RETURN_HOOK): move from vm_core.h to new file
probes_helper.h for narrowing dependency to probes.h.
* common.mk (VM_CORE_H_INCLUDES): remove dependency to probes.h.
* common.mk (vm.$(OBJEXT)): add dependency to probes_helper.h.
* vm.c, vm_insnhelper.c: include probes_helper.h.

based on r26235 by Yugui. On Solaris 10, low optimization level
may also be needed, e.g. optflags="-xO1" or "-xO0" with Oracle
SolarisStudio 12.3 cc.
* configure.in (--enable-dtrace): new option to enable/disable
DTrace support. By default, trying to enable if dtrace command
is found on the system. It is disabled when cross compiling.
* configure.in (RUBY_DTRACE_POSTPROCESS): new macro. checks whether
the dtrace on the system needs postprocessing with "dtrace -G".
The postprocessing is needed on Solaris 10 and other platforms.
* configure.in (RUBY_DTRACE_BSD_BROKEN): new macro. checks whether
the dtrace supports USDT.
* configure.in (DTRACE): move after RUBY_DTRACE_POSTPROCESS.
* configure.in (LD): On Solaris, /usr/ccs/bin/ld is preferred.
* configure.in, Makefile.in, common.mk (DTRACE_OBJ): new macro for
DTrace probe object generated by postprocessing with "dtrace -G".
* Makefile.in, common.mk (probes.$(OBJEXT)): DTrace probe object
generated by the postprocessing. New file probes.stamp is for
rebuilding related objects that may be modified by "dtrace -G".
* configure.in, Makefile.in, common.mk (DTRACE_GLOMMED_OBJ): new
macro for DTrace static library hacks.
* configure.in, Makefile.in (LIBRUBY_A_OBJS): ditto.
* Makefile.in, common.mk (ruby-glommed.$(OBJEXT)): new target with
rule for DTrace static library hacks.
* common.mk (DTRACE_DEPENDENT_OBJS): objects depended on probes.h.

characters detection and ensure wide-chars are used as pattern.

* st.c (st_update): pass the key in st_table so that we can free
memory of the key in st_table when deleting.

* test/-ext-/st/test_update.rb
(Bug::StTable#test_pass_objects_in_st_table): add a test.

when wildcard character is used. [ruby-core:49451] [Bug #7374]
