i2c-tools: Add examples to manual pages
As suggested by rpjday back in August. I tried to follow the same style
Wolfram used for the i2ctransfer examples, for consistency.

i2ctransfer: replace broken "force" handling
Probably because of a bad rebase, the old and bogus handling (v1) of "force"
slipped into the latest version of the patch (v3). Apply the better
version from v2 which does the error handling correct and makes the code
a lot easier to understand.

i2c-tools: add new tool 'i2ctransfer'
This tool allows to construct and concat multiple I2C messages into one
single transfer. Its aim is to test I2C master controllers, and so there
is no SMBus fallback.
I've been missing such a tool a number of times now, so I finally got
around to writing it myself. As with all I2C tools, it can be dangerous,
but it can also be very useful when developing.
It has been tested with various Renesas I2C IP cores as well as Tegra,
i.MX and AT91.

Enable static use of libi2c
When debugging embedded systems, it is often nice to simply TFTP the
desired i2ctool to the target without the hazzle of dealing with shared
libs. Using -static is overkill, too, so let's add a switch which will
only link functions from libi2c statically.
