Adding EPSV command into (Grid)FTP DMC to make it handle IPv6 properly for file listing. Finished fix for bug 3254.

Implementing RFC2428 in gridftpd. Partial - at least arccp works - solution for IPv6 problem described in bug 3254.

In case GridFTP client plugin is missing, only write error message and set exit code to 1 if job submission failed, otherwise write info message and set exit code to 0. Fixes bug 3235.

Russian translation: synchronising with changes due to the new job list and certificate signing algorithms

Use BDB job storage implementation by default, if available. Create configuration attribute for choosing job storage implementation to use.

Create structure for holding available job information storage implementations. Use an array to hold available implementations. Adapt unit test to use array. Remove XML locking test.

Create BDBException class and use that for throwing exceptions instead of std::exception. Thrown exceptions are and should not be propagated outside the JobInformationStorageBDB class. Move logging to BDBException constructor.

In revision 28075, reading job storage in JobInformationStorageXML class was moved to constructor, so when using JobInformationStorageXML methods consecutive the internal job store might be invalid, thus when writing and job store is invalid a new must be created before writing jobs. Fixes make check broken in revision 28075.

Move job list file checking from UserConfig to JobStorageInformation class. Check for storage in constructor. Improve log messages.

Another errors from 'X509_STORE_CTX_get_error' must be translated by 'X509_verify_cert_error_string' according to openssl man pages.

Revoking revision 28067 since PayloadTLSMCC pointer might be NULL, except for call to Logger in PayloadTLSMCC::StoreInstance method, since it is a member method.
