[Bug #1172763] dumbdbm uses eval() on lines, so it chokes if there's an extra \r on the end of a line; fixed by stripping off trailing whitespace.

arguments (left, right) like any sane comparison function.  no need to
pass in the db object as an argument.

for them in a roundabout way (catching and parsing stderr)

keeps test output clean.

DBError was supposed to be raised.

needs backport to 2.4.x and possibly 2.3.x.

bug #1215432

by Darek Suchojad)

 * the has_key() method was not raising a DBError when a database error
   had occurred. [SF patch id 1212590]
 * added a wrapper for the DBEnv.set_lg_regionmax method [SF patch id 1212590]
 * DBKeyEmptyError now derives from KeyError just like DBNotFoundError.
 * internally everywhere DB_NOTFOUND was checked for has been updated
   to also check for DB_KEYEMPTY.  This fixes the semantics of a couple
   operations on recno and queue databases to be more intuitive and results
   in less unexpected DBKeyEmptyError exceptions being raised.

On more modern linuxes (and probably others) straight 'en_US' isn't a
valid locale. Make the code try a couple of alternates.

[ 1180995 ] binary formats for marshalling floats

Adds 2 new type codes for marshal (binary floats and binary complexes), a
new marshal version (2), updates MAGIC and fiddles the de-serializing of
code objects to be less likely to clobber the real reason for failing if
it fails.

component of the path.
