Replace the insert() method (which reports an error when inserting a password with a key which already exists) with the store() method which replaces or inserts the password depending on whether the key already exists or not respectively. There is also an optimisation that nothing is changed if the password to be replaced is the same as the one already stored. The code in Win_GParted::open_encrypted_partition() is simplified now it doesn't have to implement this pattern of behaviour itself. Bug 795617 - Implement opening and closing of LUKS mappings

/* PasswordRAMStore
|
|
*
|
|
* Memory only store of passwords and passphrases. Works like an associative array with
|
|
* a unique key used to identify each password. Passwords are C strings which are stored
|
|
* in a block of the process' virtual memory locked into RAM. Looked up pointers to
|
|
* passwords are valid at least until the next time the store is modified by an insert or
|
|
* erase call. Passwords are wiped from memory when no longer wanted.
|
|
*
|
|
* Recommend using LUKS UUIDs as the key when storing LUKS passphrases.
