[issue7632] dtoa.c: oversize b in quorem, and a menagerie of other bugs

Mark, thanks for the explanation! - You can generate suppressions for the Misc/valgrind-python.supp file, but you have to know exactly which errors can be ignored.

Going through the Valgrind output again, it looks like most of it is about what you already mentioned (bd0, bd, bb, bs and delta not being released).

Would it be much work to provide Valgrind-friendly versions of Balloc, Bfree and pow5mult? Balloc and Bfree are already mentioned in an XXX
comment, pow5mult should be a slow version that doesn't cache anything. Perhaps these could be ifdef'd with Py_USING_MEMORY_DEBUGGER.
