Summary: entry size for bsddb cursors

Initial Comment:
If you store large entries in a database, there is

currently no way to get their size without reading the

whole thing into memory when using cursors. Knowing the

length is useful for doing partial reads from a record. 



The patch adds a method get_current_size() that returns

the length of the data in the current entry the cursor

is pointing at. 



Implemented at the request of the Quotient developers

(divmod.org). 



I have pybsddb cvs access so I can check in the docs

there if/when this goes in to core python.



(Patch is concatenated two files, hope it's ok.)

Okay, a working get_current_size() and test case have been committed.

This patch doesn't handle zero length values properly and misuses makeDbErr; i've got a fixed patch and test case in my sandbox currently running the testsuite.  I'll commit it shortly.
