This introduces the qemu-gdb command "qemu timers" which will dump the
state of the main timers in the system.

Since QEMU has been able to build with native Int128 support this was
broken as it attempts to fish values out of the non-existent
structure. Also the alias print was trying to make a %x out of
gdb.ValueType directly which didn't seem to work.

The following exception is threw:
Python Exception <class 'NameError'> name 'long' is not defined:
Error occurred in Python command: name 'long' is not defined
Python 2.4+, int()/long() have been unified, so replace long
with int.

get_fs_base() cannot be run on a core dump, because it uses the arch_prctl
system call. The fs base is the value that is returned by pthread_self(),
and it would be nice to just glean it from the "info threads" output:
* 1 Thread 0x7f16a3fff700 (LWP 33642) pthread_cond_wait@@GLIBC_2.3.2 ()
^^^^^^^^^^^^^^
but unfortunately the gdb API does not provide that. Instead, we can
look for the "arg" argument of the start_thread function if glibc debug
information are available. If not, fall back to the old mechanism.

As we add more commands to our Python gdb debugging support, it's
going to get unwieldy to have everything in a single file. Split
the implementation of the 'mtree' command from qemu-gdb.py into
its own module.
