Rework LuCI build system

 * Rename subdirectories to their repective OpenWrt package names
 * Make each LuCI module its own standalone package
 * Deploy a shared luci.mk which is used by each module Makefile

+--- Unified high-level I/O utility API for Files, Sockets and TLS-Sockets.
+-- These functions are added to the object function tables by doing <strong>
+-- require "nixio.util"</strong>, can be used on all nixio IO  Descriptors and
+-- are based on the shared low-level read() and write() functions.
+-- @cstyle	instance
+module "nixio.UnifiedIO"
+
+--- Test whether the I/O-Descriptor is a socket. 
+-- @class function
+-- @name UnifiedIO.is_socket
+-- @return	boolean
+
+--- Test whether the I/O-Descriptor is a TLS socket. 
+-- @class function
+-- @name UnifiedIO.is_tls_socket
+-- @return	boolean
+
+--- Test whether the I/O-Descriptor is a file. 
+-- @class function
+-- @name UnifiedIO.is_file
+-- @return	boolean
+
+--- Read a block of data and wait until all data is available.
+-- @class function
+-- @name UnifiedIO.readall
+-- @usage This function uses the low-level read function of the descriptor.
+-- @usage If the length parameter is ommited, this function returns all data
+-- that can be read before an end-of-file, end-of-stream, connection shutdown
+-- or similar happens.
+-- @usage If the descriptor is non-blocking this function may fail with EAGAIN.
+-- @param	length	Bytes to read (optional)
+-- @return	data that was successfully read if no error occured
+-- @return	- reserved for error code -
+-- @return	- reserved for error message -
+-- @return  data that was successfully read even if an error occured
+
+--- Write a block of data and wait until all data is written.
+-- @class function
+-- @name UnifiedIO.writeall
+-- @usage This function uses the low-level write function of the descriptor.
+-- @usage If the descriptor is non-blocking this function may fail with EAGAIN.
+-- @param	block	Bytes to write
+-- @return	bytes that were successfully written if no error occured
+-- @return	- reserved for error code -
+-- @return	- reserved for error message -
+-- @return  bytes that were successfully written even if an error occured
+
+--- Create a line-based iterator.
+-- Lines may end with either \n or \r\n, these control chars are not included
+-- in the return value.
+-- @class function
+-- @name UnifiedIO.linesource
+-- @usage This function uses the low-level read function of the descriptor.
+-- @usage <strong>Note:</strong> This function uses an internal buffer to read
+-- ahead. Do NOT mix calls to read(all) and the returned iterator. If you want
+-- to stop reading line-based and want to use the read(all) functions instead
+-- you can pass "true" to the iterator which will flush the buffer 
+-- and return the bufferd data.
+-- @usage If the limit parameter is ommited, this function uses the nixio
+-- buffersize (8192B by default).
+-- @usage If the descriptor is non-blocking the iterator may fail with EAGAIN.
+-- @usage The iterator can be used as an LTN12 source.
+-- @param	limit	Line limit
+-- @return	Line-based Iterator
+
+--- Create a block-based iterator.
+-- @class function
+-- @name UnifiedIO.blocksource
+-- @usage This function uses the low-level read function of the descriptor.
+-- @usage The blocksize given is only advisory and to be seen as an upper limit,
+-- if an underlying read returns less bytes the chunk is nevertheless returned.
+-- @usage If the limit parameter is ommited, the iterator returns data
+-- until an end-of-file, end-of-stream, connection shutdown or similar happens.
+-- @usage The iterator will not buffer so it is safe to mix with calls to read.
+-- @usage If the descriptor is non-blocking the iterator may fail with EAGAIN.
+-- @usage The iterator can be used as an LTN12 source.
+-- @param	blocksize	Advisory blocksize (optional)
+-- @param	limit		Amount of data to consume (optional)
+-- @return	Block-based Iterator
+
+--- Create a sink.
+-- This sink will simply write all data that it receives and optionally
+-- close the descriptor afterwards.
+-- @class function
+-- @name UnifiedIO.sink
+-- @usage This function uses the writeall function of the descriptor.
+-- @usage If the descriptor is non-blocking the sink may fail with EAGAIN.
+-- @usage The iterator can be used as an LTN12 sink.
+-- @param	close_when_done	(optional, boolean)
+-- @return	Sink
+
+--- Copy data from the current descriptor to another one.
+-- @class function
+-- @name UnifiedIO.copy
+-- @usage This function uses the blocksource function of the source descriptor
+-- and the sink function of the target descriptor.
+-- @usage If the limit parameter is ommited, data is copied
+-- until an end-of-file, end-of-stream, connection shutdown or similar happens.
+-- @usage If the descriptor is non-blocking the function may fail with EAGAIN.
+-- @param	fdout Target Descriptor
+-- @param	size  Bytes to copy (optional)
+-- @return	bytes that were successfully written if no error occured
+-- @return	- reserved for error code -
+-- @return	- reserved for error message -
+-- @return  bytes that were successfully written even if an error occured
+
+--- Copy data from the current descriptor to another one using kernel-space
+-- copying if possible.
+-- @class function
+-- @name UnifiedIO.copyz
+-- @usage This function uses the sendfile() syscall to copy the data or the
+-- blocksource function of the source descriptor and the sink function
+-- of the target descriptor as a fallback mechanism.
+-- @usage If the limit parameter is ommited, data is copied
+-- until an end-of-file, end-of-stream, connection shutdown or similar happens.
+-- @usage If the descriptor is non-blocking the function may fail with EAGAIN.
+-- @param	fdout Target Descriptor
+-- @param	size  Bytes to copy (optional)
+-- @return	bytes that were successfully written if no error occured
+-- @return	- reserved for error code -
+-- @return	- reserved for error message -
+-- @return  bytes that were successfully written even if an error occured
+
+--- Close the descriptor.
+-- @class function
+-- @name UnifiedIO.close
+-- @usage	If the descriptor is a TLS-socket the underlying descriptor is
+-- closed without touching the TLS connection.
+-- @return	true
