installing .egg-info for a project that contains no modules or packages,
while using --root (as in bdist_rpm).  (Backport from trunk)

Two changes:

Where possible, use link()/remove() to move files into a directory; this
makes it easier to avoid overwriting an existing file.

Use _create_carefully() to create files in tmp/, which uses O_EXCL.

Replace C++ comment with C comment (fixes SF bug #1593525).

Both the Maildir and MH classes had this bug; the patch fixes both classes
and adds a test.

Don't inline Py_ADDRESS_IN_RANGE with gcc 4+ either.

Prevent crash if alloc of garbage fails.  Found by Typo.pl.

Fix bug #1565514, SystemError not raised on too many nested blocks.
It seems like this should be a different error than SystemError, but
I don't have any great ideas and SystemError was raised in 2.4 and earlier.

Fix crash in test on HP-UX.  Apparently, it's not possible to delete a lock if
it's held (even by the current thread).

Fix warnings with HP's C compiler.  It doesn't recognize that infinite
loops are, um, infinite.  These conditions should not be able to happen.

Add some asserts.  In sysmodule, I think these were to try to silence
some warnings from Klokwork.  They verify the assumptions of the format
of svn version output.

The assert in the thread module helped debug a problem on HP-UX.
