When makedevs is called for a second time with the same device file,
it fails because the files already exist and mknod() gives -EEXIST.

Parse this in config files:
DEFINE col ...
DEFINE tbl ...
DEFINE nroff ...
Add width options to nroff command line.
Use "tbl", not "gtbl", as default tbl command.
Export GROFF_NO_SGR=1 and use "col -b -p -x" instead of pager when writing to file.

Commit e6a2f4cc changed the way common_bufsiz1 works. Now it needs to
be initialized before using, but i2cdump wasn't updated by said patch.
Since the fact that we're using common_bufsiz1 here isn't obvious (no
G_INIT() macro, no other global variables), drop it and simply
allocate the integer array required for block reads on the stack.
Tested with i2c block read on a Lenovo Thinkpad laptop.

The non-fancy version of the from_cpuset uses CPU_SETSIZE as if it
represents the number of bytes in the cpuset, while it is actually
the number of bits. This leads to out-of-bounds accesses on the
cpu_set_t in the big-endian case. Basically all uses of CPU_SETSIZE
have to be divided by 8. This is done correctly in the fancy version
of from_cpuset.
In addition, the big-endian case is completely wrong to begin with.
All standard C libraries that I know of implement cpu_set_t as an
unsigned long array, so both for big and little endian, the least
significant bits are in the beginning of the array. Therefore, the
approach taken for the little endian case is equally valid. We only
need special handling for big endian when CPU_SETSIZE is large and
we use an unsigned long long to get more bits out.

We should bail-out if i2c_smbus_read_block_data() or

Currently we're calling i2c_smbus_read_block_data() for both 'i' and 's'
mode parameters. If the bus doesn't support SMBus block mode, then the
i2c access ioctl() fails. Make i2cdump behave compatibly with upstream
version by calling i2c_smbus_read_i2c_block_data() for I2C block.

If the bus doesn't support SMBus Quick Write or Receive Byte commands
and we're running in auto mode all addresses will be skipped resulting
in an empty table being printed.
This is caused by not restoring the auto mode after it's been changed
for certain address ranges - we need an additional variable to hold the
temporary state.

The virtual y can be larger - and we can be even writing there since
we are taking into account the y offset. Avoids possible crash.
But use it only if set, seems it is not set if virtual area is not
allocated (though, often fbcon allocates some scrollback area).
