Increese sleep time between writes to accomodate typical write
cycle times. An Atmel AT24C02 as well as an ON Semiconductor
CAT24C02 EEPROM specify 5ms. This resolves errors such as:
...
Bus: /dev/i2c-1, Address: 0x50, Mode: 8bit
Writing stdin starting at address 0x0
..Error i2c_write_2b: Input/output error
Error at line 162: write error
[JD] Define a single constant and add a note that this could be
revisited.
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.

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.

Instead of reencoding pre-DDR3 manufacturer codes to DDR3 manufacturer
codes, move the common decoding to a separate function.

We also need to discard vendor ID 0 and to report "Unknown" if the
vendor is in a page we don't support yet.
Additionally, check that data is present at all for DDR3 modules as we
already do for pre-DDR3 modules.

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.

Contributed by Michael Göhler. My original attempt to fix it just
shows how little I know about python.

Based on a patch from Peter Missel. The meaning of byte 31, bit 1,
was inverted. Also, this bit is only meaningful if the extended
temperature range is supported (bit 0 is set.)

When you do `pydoc smbus`, you just get the high level description.
There is no automatic display of the classes (like SMBus). This is
due to the name not being specified quite right in the type.
