docs: Rename ufoo.rst to foo.rst.

This is a simple rename of the files, no content changes
(other than updating index.rst to use the new paths)

+:mod:`ucryptolib` -- cryptographic ciphers
+==========================================
+
+.. module:: ucryptolib
+   :synopsis: cryptographic ciphers
+
+Classes
+-------
+
+.. class:: aes
+
+    .. classmethod:: __init__(key, mode, [IV])
+
+        Initialize cipher object, suitable for encryption/decryption. Note:
+        after initialization, cipher object can be use only either for
+        encryption or decryption. Running decrypt() operation after encrypt()
+        or vice versa is not supported.
+
+        Parameters are:
+
+            * *key* is an encryption/decryption key (bytes-like).
+            * *mode* is:
+
+                * ``1`` (or ``ucryptolib.MODE_ECB`` if it exists) for Electronic Code Book (ECB).
+                * ``2`` (or ``ucryptolib.MODE_CBC`` if it exists) for Cipher Block Chaining (CBC).
+                * ``6`` (or ``ucryptolib.MODE_CTR`` if it exists) for Counter mode (CTR).
+
+            * *IV* is an initialization vector for CBC mode.
+            * For Counter mode, *IV* is the initial value for the counter.
+
+    .. method:: encrypt(in_buf, [out_buf])
+
+        Encrypt *in_buf*. If no *out_buf* is given result is returned as a
+        newly allocated `bytes` object. Otherwise, result is written into
+        mutable buffer *out_buf*. *in_buf* and *out_buf* can also refer
+        to the same mutable buffer, in which case data is encrypted in-place.
+
+    .. method:: decrypt(in_buf, [out_buf])
+
+        Like `encrypt()`, but for decryption.
