Revert "FS: Fix backward conditional logic that prevent unlink() from building in some configurations."
Oops. It was not backward. Enable == !Disable. Negative logic is confusing.
This reverts commit 1fcf353e89 .

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.

Add support for a variadic ioctl() function. The ioctl() interface is a non-standard, Unix interface. NuttX has always used the older, three-parameter version. Most contemporary systems now, however, use a variadic form of the ioctl() function. Added an option to insert a shim layer to adapt the three-parameter ioctl() to use the variadic interface form. Internally, the ioctl handling is the same three-parameter logic. The only real complexity to the shim is in how the system calls must be handled.
