(ITS#6689) Patch - Mozilla NSS - support cert database prefix

Full_Name: Rich Megginson Version: 2.4.23 (current CVS HEAD) OS: RHEL5 URL: ftp://ftp.openldap.org/incoming/openldap-2.4.23-moznssdbprefix-20101028.p... Submission from: (NULL) (76.113.111.209) Mozilla NSS supports having multiple cert/key databases in the same directory, each one having a unique string prefix e.g. slapd-01-cert8.db - the prefix here is "slapd-01-" This patch allows the user to pass in the prefix as the last part of the cacertdir. If the given cacertdir does not exist (neither a file nor a directory), and contains the platform's path separator character (e.g. '/'), look at the last occurance of the path separator in the string - if it exists and there is something after that, assume that is the prefix. This patch also cleans up some compiler warnings about unused variables and signedness differences, and removes a very annoying debug message. This patch file is derived from OpenLDAP Software.
