When unloading the driver, we really want to unregister the i2c adapter
before we power it off, rather than the other way around.
Also speed up the bus a bit when we can sense SCL. The slaves will
stretch the line as needed.

Initialize the fields of the i2c_adapter structure individually,
rather than copying a whole static template structure. This shaves
off 474 bytes or 14% (on i386) from the binary size.

i2c-algo-bit: Discard the mdelay data struct member
The i2c_algo_bit_data structure has an mdelay member, which is not
used by the algorithm code (the code has always been ifdef'd out.)
Let's discard it to save some code and memory.

This patch forces the user to specify what type of adapter is present when
loading i2c-parport or i2c-parport-light. If none is specified, the driver
init simply fails - instead of assuming adapter type 0.
This alleviates the sometimes lengthy boot time delays which can be caused
by accidentally building one of these into a kernel along with several i2c
slave drivers that have lengthy probe routines (e.g. hwmon drivers).
Kconfig and documentation updated accordingly.

Use ARRAY_SIZE macro instead of sizeof(x)/sizeof(x[0]). Some trailing
whitespaces are also removed.

It's a bit confusing to name a variable the same as an unrelated
structure. The compiler doesn't complain, but it certainly makes the
code harder to understand, and could confuse grep and LXR among
others.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
