ubifs: convert to ctime accessor functions
In later patches, we're going to change how the inode's ctime field is used. Switch to using accessor functions instead of raw accesses of inode->i_ctime.

ubifs: fix snprintf() checking
The snprintf() function returns the number of characters (not counting the NUL terminator) that it would have printed if we had space.
This buffer has UBIFS_DFS_DIR_LEN characters plus one extra for the terminator. Printing UBIFS_DFS_DIR_LEN is okay but anything higher will result in truncation. Thus the comparison needs to be change from == to >.
These strings are compile time constants so this patch doesn't affect runtime.

ubifs: Limit dumping length by size of memory which is allocated for the node
To prevent memory out-of-bounds accessing in ubifs_dump_node(), actual dumping length should be restricted by another condition(size of memory which is allocated for the node).
This patch handles following situations (These situations may be caused by bit flipping due to hardware error, writing bypass ubifs, unknown bugs in ubifs, etc.): 1. bad node_len: Dumping data according to 'ch->len' which may exceed the size of memory allocated for node. 2. bad node content: Some kinds of node can record additional data, eg. index node and orphan node, make sure the size of additional data not beyond the node length. 3. node_type changes: Read data according to type A, but expected type B, before that, node is allocated according to type B's size. Length of type A node is greater than type B node.

So fix this up properly.

ubifs: no need to check return value of debugfs_create functions
When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this.

ubifs: Format changes for authentication support
This patch adds the changes to the on disk format needed for authentication support. We'll add:
* a HMAC covering super block node * a HMAC covering the master node * a hash over the root index node to the master node * a hash over the LPT to the master node * a flag to the filesystem flag indicating the filesystem is authenticated * an authentication node necessary to authenticate the nodes written to the journal heads while they are written. * a HMAC of a well known message to the super block node to be able to check if the correct key is provided
And finally, not visible in this patch, nevertheless explained here:
* hashes over the referenced child nodes in each branch of a index node

ubifs: Rework ubifs_assert()
With having access to struct ubifs_info in ubifs_assert() we can give more information when an assert is failing. By using ubifs_err() we can tell which UBIFS instance failed.
Also multiple actions can be taken now. We support: - report: This is what UBIFS did so far, just report the failure and go on. - read-only: Switch to read-only mode. - panic: shoot the kernel in the head.
