This patch changes a lot of the code in ldb_dn.c, and also removes and add a number of manipulation functions around. The aim is to avoid validating a dn if not necessary as the validation code is necessarily slow. This is mainly to speed up internal operations where input is not user generated and so we can assume the DNs need no validation. The code is designed to keep the data as a string if possible. The code is not yet 100% perfect, but pass all the tests so far. A memleak is certainly present, I'll work on that next. Simo.
