parser: use PyInt_FromSsize_t in index_stats

Eliminates

  mercurial/parsers.c(515) : warning C4244: 'function' : conversion from
  'Py_ssize_t' to 'long', possible loss of data
  mercurial/parsers.c(520) : warning C4244: 'function' : conversion from

  mercurial/parsers.c(521) : warning C4244: 'function' : conversion from

when compiling for Windows x64 target using the Microsoft compiler.

PyInt_FromSsize_t does not exist for Python 2.4 and earlier, so we define a
fallback in util.h to use PyInt_FromLong when compiling for Python 2.4.

# simple script to be used in hooks
#
# put something like this in the repo .hg/hgrc:
#
#     [hooks]
#     changegroup = python "$TESTDIR"/printenv.py <hookname> [exit] [output]
#
#   - <hookname> is a mandatory argument (e.g. "changegroup")
#   - [exit] is the exit code of the hook (default: 0)
#   - [output] is the name of the output file (default: use sys.stdout)
#              the file will be opened in append mode.
