tmem: cleanup: rename 'tmh_' with 'tmem_'

tmem was designed can be ported to other platform besides xen easily, but I
don't think anybody will port tmem to other platform. And this flexible
character made tmem not easy for understand, there are too many 'tmh_' and
'tmem_' functions and variables.

This patch replace all 'tmh_' functions/variables with 'tmem_' to make code
more readable.

get_maintainer.pl: Adjust to Xen workflow

Based on feedback from reviewers:
* Disable git fallback by default: it has a tendency to mail
  anyone who did a single oneline change and should not be
  necessary for a project of Xen's size.
* Disable rolestats: Makes cut-and-paste from the output into the
  commit message easy.
* Drop "THE REST" fallback: Don't spam Keir *too* much.

libxl: change most remaining LIBXL_LOG to LOG in libxl_qmp.c

Coding style has recently been changed for libxl. The convenience
macro LOG() has been introduced, and invocations of the old macro
LIBXL__LOG() are to be replaced with it. Change occurences of the
old macro to the new one in the functions qmp_handle_response()
and qmp_handle_error_response(). The new macros need access to a
local libxl__gc *gc, so add it as a parameter to both these functions,
and pass the instance in qmp_next() down the call chain to
qmp_handle_response() and in turn to qmp_handle_error_response().

libxl: Use new macro LOGE() in libxl_qmp.c

Code cleanup -- no functional changes

Coding style has recently been changed for libxl. The convenience
macro LOGE() has been introduced, and invocations of the old macro
LIBXL__LOG_ERROR() are to be replaced with it. Change all occurences
of the old macro (in functions that have a local libxl_gc *gc) except
the one in register_serials_chardev_callback() to the new one. (This
function lacks a local libxl__gc *gc, which LOGE() requires.)

libxl: use LOGE instead of LIBXL__LOG_ERRNO in libxl_utils.c

Code cleanup - no functional changes

The convenience macro LOGE has been written to take the place of
LIBXL__LOG_ERRNO. LOGE depends on the existence of a local libgl__gc
*gc. Replace two invocations of LIBXL__LOG_ERRNO, which are in
functions that already have a libxl__gc *gc present, to invocations
of the new macro.

libxl: use LOG and LOGE instead of LIBXL__LOG* in libxl_utils.c

Code cleanup - no functional changes

The convenience macros LOG and LOGE have been written to take the
place of the old macros in the LIBXL__LOG* family. Replace the
invocations of the old macros in the function libxl_read_file_contents()
with invocations of the corresponding new ones. Create a local
libxl__gc gc* for the new macros to use by invoking GC_INIT(ctx) at the
top of the function, and clean it up by invoking GC_FREE at the two
exit points.
