3f6aae03c9 Fix assert in gdbserver for watchpoints watching the same address
GDB can create watchpoints watching the same address.
This was causing assertion failures.
To handle this, hash table (with key watched address) is replaced
by an xarray of address/lengh/kind.
Fully identical watches are ignored (either not inserted, and
not causing a problem if already deleted).

gdbserver_tests/mcwatchpoint enhanced to test duplicated watchpoints

b37b05d214 Improvements for testing and compilation breakage for the GDB server
on various platforms:

* In all gdbserver_tests using gdb:
  Made a more general way to remove the initial start message.

* tests using threads burning cpu modified to have only 1 thread.
  This makes them independent of the scheduler fairness.

* filter_gdb and filter_vgdb enhanced to anonymise
    some debian 6.0/ppc specific things
    some s390x/gdb 7.0, gdb 7.1  specific things

* vgdb.c: added an #include <linux/ptrace.h> to fix compilation
  on s390x fedora and suse. (Christian Boerntrager)

* fixed a bug in valgrind-low.c debug log :
  when a register size is 0, its image cannot be output (and register
  should not be transferred).

* added a parameter --keep-unfiltered to vg_regtest.in
  This will make it easier to update filter_gdb:
  in case gdbserver_tests are failing due to "artificial"
  differences to be filtered, re-run the tests using:
     perl tests/vg_regtest --keep-unfiltered gdbserver_tests
  Then a tar file with all the *.out in gdbserver_tests
  will allow me to better/faster update the filter_gdb.

* made a better detection of a working PTRACE_GETREGS at compile time
  and/or at run-time.

This is the patch on bug 214909 comment 69.
