Add an option -h to display the help of the tools. This is a common
practice so users may expect it to work.
Based on a preliminary patch from David Kerns.

For all manpages installed on my Debian system, add a BUGS section, so
people can easily find whom to contact.

The I2C standard reserves addresses 0x03-0x07. Adapt our tools to that.

The text describing the address to be used did not reflect the recent
change where some of the functionality of '-f' has been seperated into
'-a'.

We now have the flag '-a' for all i2c-tools to allow access for all
addresses. This was tied in i2ctransfer to the '-f' flag. Remove it and
keep that feature to '-a' only. This is also more in sync with the other
i2c-tools which use '-f' only to access already busy devices.

If the user is sure that the reserved 0x00 - 0x02 and 0x77 - 0x7f ranges
are not needed by its devices, then the "-a" option can be passed for
allowing all theorical addresses to be used. It is then possible to
access devices in this address range.

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.
