On some SPI NOR flashes you can actually erase the OTP region until its
fully locked. Add a small utility for that.

The nandflipbits tool is intended to be used when one need to flip one or
several specific bits on a NAND media.
It can be useful to manually recover from an unexpected bit flip on a flash
device, though the main purpose of this tool is to provide a way to test
ECC algorithms robustness.
One typical example I used this tool for is testing HW ECC engines behavior
when bitflips occur in an erased page: most HW engines do not correctly
handle this case, because, most of the time, ECC bits generated for an
empty page are not all 1s, and, empty page detection embedded in such
engines is only validating that all bits are set to 1s (which is not true
when a bit-flip has occurred).
Another use of this tool is replacing nandbiterrs test which
absolutely do not work with MLC-like chips because of the rewriting of
the pages in raw mode to toggle ones into zeroes.

This patch adds a program called "lsmtd". The program produces a pretty
printed list of the hierarchy of UBI and MTD devices on a system. It
tries to imitate the lsblk program from util-linux as closely as
possible.
A number of command line switches are available to fine tune what information
should be exposed and in what output format.
The goal is to have a simple way of displaying the complete MTD stack on
a system in a human readable form instead of piecing details together
from proc files and various UBI utilities.

Compiling for x86_64 generates a lot of warning because the PRIxoff_t and
PRIdoff_t are not properly defined, which comes from the missing
SIZEOF_LONG definition.
Use the autotools to generate a config.h header, include this header from
common.h and ask autoheader to generate the SIZEOF_LONG and SIZEOF_LOFF_T
definitions.
Use these new definitions to assign the proper descriptors to PRIxoff_t
and PRIdoff_t.

Basically a user space port of the mtd sub page test kernel module.
In addition to the module parameters, the utility supports using
only a sub-range of the flash erase blocks with a configurable
stride and can restore the block contents after the test.

Basically a user space port of the mtd speed test kernel module.
In addition to the block offset and count module parameters, the
utility supports a block stride and can restore the block contents
after test. Furthermore, a flag can be used to disable destructive
tests (i.e. only perform read speed tests).

Basically a user space port of the mtd torture test kernel module. In
addition to the block offset and count module parameters, the utility
supports a block stride and can restore the block contents after test.
In contrast to the kernel module, the torture test is implemented by
the libmtd mtd_toruture function and thus doesn't allow for similarly
fine grained options on diagnostics.

This patch is largely based on Richards original RFC.
The major differences to the RFC patch are:
- Add missing sumtools & mtdpart targets
- Fix name of mkfs.jffs2 target
- Add missing subdir-objects option for non-recursive make
- Move all automake options to configure.ac
- Add manpages to install target
- Make XATTR & LZO support configurable
- Install binaries to sbin directory like in the old build system
- Install flash_erase wrapper script
- Add files missing from distribution target

* 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

First, the top-level Makefile should not tell git to ignore sub-level
.gitignore files.
Second, add simple .gitignores to ignore the executables generated under
the various `tests' subdirectories.

Linux FLAT toolchains produce .gdb files alongside the normal program
for debugging purposes (so linking to "foo" will also produce "foo.gdb").
Ignore these too.

These have overlapping functionality, and while flash_eraseall supports
newer 64bit ioctls, flash_erase does not. So rather than graft support
onto flash_erase, merge the functionality of two into flash_erase so we
only have to support one util from now on.
A simple wrapper is provided to ease old flash_eraseall users into the
new combined flash_erase util.
