Append/prepend commands.
Introduce new storage commands "append" and "prepend" for atomic value
modification. They follow generic storage commands interface as described in
doc/protocol.txt:
<command name> <key> <flags> <exptime> <bytes>\r\n
<data block>\r\n
Current implementation involves memcpy() twice to combine values on writing
(i.e. full resulting value are copied), but truly atomic (and even threadsafe).
