This patch solves 2 problems of the os module.
1) Bug ID #50 (case-mismatch wiht "environ.get(..,..)" and "del environ[..]")
2) os.environ.update (dict) doesn't propagate changes to the 'real'
   environment (i.e doesn't call putenv)

This patches also has minor changes specific for 1.6a
The string module isn't used anymore, instead the strings own methods are
used.

The bug is in mmap_read_line_method(), and its loop that searches for
newlines.  After the loop reaches EOF, eol is incremented and points
after the end of the memory.  This results in readline() method
sometimes picking up and returning a byte after the end of the string.
This is usually a bogus \0, but it could cause SIGSEGV if it's after
the end of the page).

The patch fixes the problem.  Also, it uses memchr() for finding a
character, which is in fact the "strnchr" the comment is asking for.
memchr() is already used in Python sources, so there should be no
portability problems.

I didn't make these deprecation notices since it was never a
documented feature.

backwards compatibility, and to avoid a revolution.

Unix From lines, change the UnixMailbox class so that _search_start()
positions the file *before* the Unix From line instead of after it;
change _search_end() to skip one line before looking for the next From
line.  The rfc822.Message class automatically recognizes these Unix
From lines and squirrels them away in the 'unixfrom' instance variable.

  - file_util.py: operations on single files
  - dir_util.py: operations on whole directories or directory trees
  - dep_util.py: simple timestamp-based dependency analysis
  - archive_util.py: creation of archive (tar, zip, ...) files
The functions left in util.py are miscellany that don't fit in any of the
new files.

the Command class from core.py to cmd.py.  No other code needs changing
though; distutils.core still provides the Command and Distribution classes,
although indirectly now.

(Very rough.)

Hopefully I got all this right!
