nuttx: use lib_free for memory de-allocation after strdup or asprintf
...
The memory allocated with strdup and asprintf is done via lib_malloc
so we need to use lib_free to deallocate memory otherwise the assertion
"Free memory from the wrong heap" is hit with flat mode and user separated
heap enabled mode.

Check return from nxsem_wait_initialize()
...
Resolution of Issue 619 will require multiple steps, this part of the first step in that resolution: Every call to nxsem_wait_uninterruptible() must handle the return value from nxsem_wait_uninterruptible properly. This commit is only for those files under fs/inode. Utility functions under fs/incode were modified so the changes do extend to other fs/ sub-directories as well.

rename(): Correct more issues. (1) Move to the root directory in the pseudo file system, (2) Fix path naming calculation when the path is the root directory of a mounted file system, and (3) dont't do the rename if the source and destination of the rename are the same.

Add logic to VFS rename: If target of rename exists and is a directory, then the source file should be moved 'under' the target directory. POSIX also requires that if the target is a file, then that old file must be deleted.

inode_find: Now takes struct inode_desc_s type as input. This was necessary before that structure includes some data storage. It was used within inode_find(), but that means that the life of the data was the life of inode_find(). That data must persist longer. It is now provided by the caller so that the life of the data persists for the entire life of the caller.
