Initialize libsym early in trace.c to help the compiler.
GCC 4.4.7 isn't smart enough to realize own_libsym will always be zero
when it sees the goto done which might jump over the initialization of
libsym. And so will produce a warning like:
cc1: warnings being treated as errors
trace.c: In function ‘ifunc_ret_hit’:
trace.c:1433: error: ‘libsym’ may be used uninitialized in this function

Partial support of IFUNC tracing on PPC32

Add support for tracing of IRELATIVE PLT entries
- Because the IRELATIVE entries have no associated symbol name, we
need to allow arch_elf_add_plt_entry to override the name. This is
done by that callback returning PLT_OK and returning the new symbol
via libsym-chain return argument. Filtering is postponed until we
have that symbol, and the filter is applied to the whole returned
chain.
- Add linux_elf_add_plt_entry_irelative to support proper naming of
IRELATIVE PLT entries. This needs to be called from arch backend,
as the numbers of IRELATIVE relocations differ per-architecture.

Instead of smuggling the vfork return breakpoint back, ref it once more
- Before we would let the breakpoint be removed and later reinserted it.
But that's unnecessarily cumbersome, and besides breaks on ARM Thumb,
where the reinserted breakpoint would be ARM breakpoint instead of
Thumb. This is easier and fixes that issue.

GNU/Linux software singlestepping: store breakpoints, not addresses
The reason being that the actual breakpoint address might be different
from the address requested. One example is Thumb, where Thumb
breakpoints are requested for address+1 (lowest bit set). Whether
this is clean solution is very questionable though.

Change DICT_FIND to DICT_FIND_{REF,VAL}
- In many places, DICT_FIND was awkward to use, as it required the use
of pointers even in cases that the dictionary already stored
pointers. For those cases, add DICT_FIND_VAL.
- Rename the original DICT_FIND to DICT_FIND_REF to make the
disctinction clear. That is useful if the dictionary holds actual
structures.

Remove hacks for SPARC code
Simply continuing on SPARC is probably broken. The breakpoint isn't
disabled at that point, and continuing just hits it again.
That __ia64___ in ifdef is never defined even on an IA64 machine.

Rename atomic singlestep to software singlestep
- The old name came from PPC implementation, where the feature was used for
skipping atomic instructions. But this is more useful, was reused for
fully software singlestepping on MIPS, and will be similarly used for ARM.
So rename the interface, and make the prototype more explicit.
- Also document the method in backend.h.
- And convert several void*'s to arch_addr_t's while there.

Don't queue sysret events
- That's because on s390x, we use process call stack to actually figure out
whether it's a syscall/sysret event, and if it's sysret, then what syscall
it returns from. So we need to keep the stack in sync with reality.

More robust fix of signal-before-singlestep problem
- On s390x, when we PTRACE_CONT the process, it will actually continue,
even though we ordered PTRACE_SINGLESTEP before. So always issue
PTRACE_SINGLESTEP when we get signal before singlestep.
- Also, simply queue the signal as usual.

Work around some odd behavior of PTRACE_DETACH after PTRACE_SINGLESTEP
- this might turn out to be a bug in the kernel that I'm using right now.
The thing that when task is detached right after it was singlestepped
(and the singlestep is caught by waitpid), it's immediately killed by
the SIGTRAP signal. This goes away if we insert breakpoint right under
the IP, CONT the process, catch the breakpoint event, retract the
breakpoint, and detach _then_.

Fix serious race in attach to many-threaded process
- the gist is that tasks continue running while we attach, so more tasks
come into existence, or the ones that we didn't attach to yet disappear,
etc.
- besides, we really can't enable breakpoints before we are done attaching,
otherwise the still-running tasks risk running into them and dying of
SIGTRAP.
