Use same code path for reading data (not the OOB) from either the
standard input or a regular file.

Fixed broken behavior in case of write failure. More specifically:
- Only try to mark a block bad if the errors are EIO. Other errors
will abort the tool.
- Also abort the tool if the marking fails instead of ignoring it.

Fix nandwrite to return EXIT_FAILURE in case of error when using the
standard input instead of a file for input.

If the file contains only a few bytes in the last page and the
--oob option is selected, the loop may exit early
(readlen < meminfo.oobsize).
Most of the time it will still work though because the code
tries to read the whole OOB in one chunk.

The "read" syscall does not necessarily return all the requested
data, in which case the caller has to try again and read more.
Take this into account when reading input data.
This patch is an improved vestion of the original patch sent by
Hai Zaar.

Added include directive for stdbool.h and leveraged where appropriate
to improve code readability by making variable intent and usage more

Static-qualified all globals except 'main' because they have no use
beyond file scope.
Constant-qualified MTD device and input positional parameter globals.

The $Id:$ tags are left over from the old CVS repository. Several files have
since been changed, and they generally have little value in a git repo so they
should be removed.

Older kernel do not implement the MTDFILEMODE ioctl. In this case
nandwrite and nanddump should have used MEMGETOOBSEL in combination
with MEMSETOOBSEL. Unfortunately the return value of the unsucessfull
ioctl is not -ENOTTY, but -1 and errno contains ENOTTY. This change
fixes this issue. I have not tested all cornercases. Would be
good if someone could do more careful testing than I did, or maybe
reviewing is sufficient in this case.

The NAND rework exposes more information to userspace and
has a different mechanism to read raw FLASH contents without
ECC. Update nanddump and nandwrite. Use the new ECC statistics
ioctl to inform the user about corrected and uncorrectable
bitflips.
