Routine Description:

    This routine is used to encrypt/decrypt the entire database in system context. The routine checks that
    the CSC database is hosted on a filesystem that allows encryption. Only admins can do the conversion
    

Arguments:

    fEncrypt    if TRUE, we encrypt the database else we decrypt.
    
    LPCSCPROCW  callback proc. The usual set of CSCPROC_REASON_BEGIN, CSCPROC_REASON_MORE_DATA, CSC_PROC_END
                are sent when the conversion actually begins. Conversion can fail if a file is open or for
                some other reason, in which case the second to last parameter in the callback with 
                CSCPROC_REASON_MORE_DATA has the error code. The third to last parameter indicates whether
                the conversion was complete or not. Incomplete conversion is not an error condition.
    
    dwContext   callback context

Returns:

    TRUE if no errors encountered.

Notes:


    Theory of operations:
    
        The CSC database encryption code encrypts all the inodes represented by remote files.
        Who: Only user in admingroup can do encryption/decryption. This is checked in kernel
        Which context: Files are encrypted in system context. This allows files to be shared
                       while still being encrypted. This solution protects from a stolen laptop case.
                       
        The database can have the following status set on it based on the four encryption states:
        
        a) FLAG_DATABASESTATUS_UNENCRYPTED b) FLAG_DATABASESTATUS_PARTIALLY_UNENCRYPTED
        c) FLAG_DATABASESTATUS_ENCRYPTED d) FLAG_DATABASESTATUS_PARTIALLY_ENCRYPTED
        
        In states a) and b) new files are created unencrypted. In states c) and d) new files are created encrypted.
        
        At the beginning of the conversion, the database stats is marked to the appropriate XX_PARTIAL_XX
        state. At the end, if all goes well, it is transitioned to the final state.
        At the time of enabling CSC, if the database state is XX_PARTIAL_XX, the kernel code tries to
        complete the conversion to the appropriate final state.
