[ 558914 ] Build md5.c fails on Cray T3E

I've also deleted a comment that I didn't understand.  Feel free to
put it back if it makes/made sense to you.

Using Unicode-aware methods may still die with a NameError on unicode.
Maybe there's a more elegant solution but I doubt anybody cares.)

literals must not contain \u, \U or \N escapes.  (XXX Should they also

before passing it to fopen().

Fixes #561326.

(or how do I "mark" something to be a candidate?)

fixed an old buglet that caused bdb to be unable to
continue in the botframe, after a breakpoint was set.
the key idea is not to set botframe to the bottom level frame,
but its f_back, which actually might be None.
Additional changes: migrated old exception trick to use
sys._getframe(), which exists both in 2.1 and 2.2 .

Note: I believe Mark Hammond needs to look over his code now.
F5 correctly starts up in the debugger, but later on doesn't stop at a given
breakpoint any longer.

Remove 1.5.2 reference: who cares?
