Revert ubi-tools changes
Restore ubi tools to their "original" state, which means to the state they were before I stareted cleaning them up. Instead, create a "new-utils" subdirectory and move my work there. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

+This directory contains a new UBI toolchain which is intended to replace
+the old one. All the utilities start with "ubi-" to distinguish them from
+the old utilities. All support "-h" option which prints sufficient usage
+information. See the MTD web-site for more information.
+
+Motivation for new tool-chain.
+
+I was doing very active UBI development and had to add new features like
+dynamic UBI devices and auto-resize feature. Because of the mess in the
+the old tools I basically could not figure out how to upgrade them. In
+my humble oppinion, they are unmaintainable. The original authors did not
+show enthusiasm when I mailed them and asked to clean-up the tool-chain
+[1]. Thus, I re-implemented them, but I did borrow things from the old
+tool-chain and preserved copyrights and author names.
+
+I really did try to clean-up the old tool chain, but gave up (see git
+history for confirmation). So,
+
+1. I found the source codes very difficult to navigate and read, especially
+ those related to pdd, pfi, and bootenv. Try to do this yourself - they
+ are a puzzle.
+2. I foud the concept of PFI needlesly complecated - PFI file is nothing
+ else but the initial configuration .ini file + the contents of the
+ UBI volumes packed into one file, but with some changes of the .ini file's
+ format. The PFI file format is not very nice and it is difficult to parse,
+ especially because the PFI headers do not tell you data star and end for
+ each data chunk, and you have to do additional parsing.
+
+ So basically, you have .ini file + images, then you transfer this to pfi,
+ which does not add any other information. For .ini you have libraries
+ which may parse them, for pfi - not. Then you have to parse this pfi
+ which adds unneeded and complex code. This all needs lists, hashmaps,
+ and so on - for no reason.
+3. I found the command line options of the utilities to be inconsistent.
+ This is OK when you script your single task and do not touch it anymore.
+ But when you have to use the utilities while developing and testing,
+ It is difficult to remember their inconsistent options.
+4. I found it wrong to add development options to user utilities like
+ "broken update". End users should not see them.
+5. I did not find any consistent style and convention inside which
+ irritated me.
+6. I found it weird to introduce needless "logging infrastructure" instead
+ of just re-directing stdout and stderr to another file.
+7. I found the tool to be rather IBM-setup oriented. For example, the VID
+ header position was hard-coded. Some utilities were just weird, like
+ mkbootenv, which changed some ethernet addresses mentioned in a
+ configuration file.
+8. Finally, it was very difficult to realize what is pfi and pdd, what for,
+ why I need this transiant pfi file when I just want to create an UBI
+ image. There was zero documentation.
+
+And so on.
+
+Feb 19, 2008, Artem Bityutskiy.

+ * COPYRIGHT (C) 1986 Gary S. Brown. You may use this program, or
+ * code or tables extracted from it, as desired without restriction.
+ *
+ * First, the polynomial itself and its table of feedback terms. The
+ * polynomial is
+ * X^32+X^26+X^23+X^22+X^16+X^12+X^11+X^10+X^8+X^7+X^5+X^4+X^2+X^1+X^0
+ *
+ * Note that we take it "backwards" and put the highest-order term in
+ * the lowest-order bit. The X^32 term is "implied"; the LSB is the
+ * X^31 term, etc. The X^0 term (usually shown as "+1") results in
+ * the MSB being 1
+ *
+ * Note that the usual hardware shift register implementation, which
+ * is what we're using (we're merely optimizing it by doing eight-bit
+ * chunks at a time) shifts bits into the lowest-order term. In our
+ * implementation, that means shifting towards the right. Why do we
+ * do it this way? Because the calculated CRC must be transmitted in
+ * order from highest-order term to lowest-order term. UARTs transmit
+ * characters in order from LSB to MSB. By storing the CRC this way
+ * we hand it to the UART in the order low-byte to high-byte; the UART
+ * sends each low-bit to hight-bit; and the result is transmission bit
+ * by bit from highest- to lowest-order term without requiring any bit
+ * shuffling on our part. Reception works similarly
+ *
+ * The feedback terms table consists of 256, 32-bit entries. Notes
+ *
+ * The table can be generated at runtime if desired; code to do so
+ * is shown later. It might not be obvious, but the feedback
+ * terms simply represent the results of eight shift/xor opera
+ * tions for all combinations of data and CRC register values
+ *
+ * The values must be right-shifted by eight bits by the "updcrc
+ * logic; the shift must be unsigned (bring in zeroes). On some
+ * hardware you could probably optimize the shift in assembler by
+ * using byte-swap instructions
