mtd-utils: Restructure the mtd-utils source.

* There is no code modification in this commit, only moving
* the files to proper place.

The user tools looks a little messy as we place almost
the all tools in the root directory of mtd-utils. To make
it more clear, I propose to introduce the following structure
for our source code.

mtd-utils/
	|-- lib
	|-- include
	|-- misc-utils
	|-- jffsX-utils
	|-- nand-utils
	|-- nor-utils
	|-- ubi-utils
	|-- ubifs-utils
	`-- tests

- * Note about LZO compression.
- *
- * We want to use the _999_ compression routine which gives better compression
- * rates at the expense of time. Decompression time is unaffected. We might as
- * well use the standard lzo library routines for this but they will overflow
- * the destination buffer since they don't check the destination size.
- *
- * We therefore compress to a temporary buffer and copy if it will fit.
