If valgrind is started with --vgdb-prefix arg, then callgrind_control
cannot find and control this valgrind.
So, add an (optional) argument to callgrind_control,
and have callgrind tool report the needed vgdb prefix argument
if the user supplied this arg.

The semantics of XEN_DOMCTL_gethvmcontext are little interesting.
If the 'buffer' field of the structure is NULL, the hypercall is a request for
the required buffer size, which written into the 'size' paramater.
If 'buffer' is non NULL, Xen will write to the buffer, and update 'size' with
the amount of data written.

The exiting thread will have its registers considered as not reachable
anymore, registers of other threads will be considered reachable.
This is ensured by using a different exit reason for the
exiting thread and for the other threads.

Option -v outputs a list of used suppressions. This only gives
the nr of times a suppression was used.
For a leak search, this only gives the nr of loss records that
have been suppressed, but it does not give additional needed details
to understand more precisely what has been suppressed
(i.e. nr of blocks and nr of bytes).
=> Add in the tool interface update_extra_suppression_use and
print_extra_suppression_info functions to allow the tool to record
additioonal use statistics for a suppression. These statistics
can be done depending on the error (and its data) which is suppressed.
Use this in memcheck for the leak suppressions, to maintain and output
the nr of blocks and bytes suppressed by a suppression during
the last leak search.

* Remove dead code in m_oset.c VG_(OSetGen_ResetIterAt)
The code at the end of VG_(OSetGen_ResetIterAt) was unreachable
(detected by BEAM checker).
Looking at SVN, the initial commit of VG_(OSetGen_ResetIterAt)
already contained this deadcode.
* pub_tool_oset.h was wrongly indicating that signed words could
be used for fast cmp oset.
* modified memcheck/tests/unit_oset.c to test VG_(OSetGen_ResetIterAt)
* modified memcheck/tests/unit_oset.c to not use signed words
(it was previously using signed words, but only with positive values)

to put a "marker" msg in process log output
* v.info n_errs_found accepts optional msg, added in the output of
the monitor command.
* use VG_(printf) rather than VG_(gdb_printf) when output of command
should be redirected according to v.set gdb_output|log_output|mixed_output
* also avoid calling gdb_printf in output sink processing
to output zero bytes, as gdb_printf expects to have a null terminated
string, which is not ensured when 0 bytes have to be output.
* some minor reformatting (replace char* xxx by char *xxx).

If a suppression file contains an error, the lineno reported could be wrong.
Also, give filename and lineno of the used suppressions in -v debugging output.
The fix consists in ensuring that tool specific read_extra function gets
the Int* lineno pointer, together with other VG_(get_line) parameters.
