doc_rst: rename the media Sphinx suff to Documentation/media

The name of the subsystem is "media", and not "linux_tv". Also,
as we plan to add other stuff there in the future, let's
rename also the media uAPI book to media_uapi, to make it
clearer.

No functional changes.

+Synopsis
+--------
+
+.. cpp:function:: int  open(const char *deviceName, int flags)
+
+
+Arguments
+---------
+
+.. flat-table::
+    :header-rows:  0
+    :stub-columns: 0
+
+
+    -  .. row 1
+
+       -  const char \*deviceName
+
+       -  Name of specific video device.
+
+    -  .. row 2
+
+       -  int flags
+
+       -  A bit-wise OR of the following flags:
+
+    -  .. row 3
+
+       -
+       -  O_RDONLY read-only access
+
+    -  .. row 4
+
+       -
+       -  O_RDWR read/write access
+
+    -  .. row 5
+
+       -
+       -  O_NONBLOCK open in non-blocking mode
+
+    -  .. row 6
+
+       -
+       -  (blocking mode is the default)
+
+
+Description
+-----------
+
+This system call opens a named ca device (e.g. /dev/ost/ca) for
+subsequent use.
+
+When an open() call has succeeded, the device will be ready for use. The
+significance of blocking or non-blocking mode is described in the
+documentation for functions where there is a difference. It does not
+affect the semantics of the open() call itself. A device opened in
+blocking mode can later be put into non-blocking mode (and vice versa)
+using the F_SETFL command of the fcntl system call. This is a standard
+system call, documented in the Linux manual page for fcntl. Only one
+user can open the CA Device in O_RDWR mode. All other attempts to open
+the device in this mode will fail, and an error code will be returned.
+
+
