Subject: i2c: Various fixes, extensions, documentation.

-Fix clock calculations for fast-mode support
-Add I2C_REMAP option to remap i2c1 (untested)
-Add I2C_BUS_RESET option to reset bus on initialization
-Add optional timeout parameter
-Doxygen comments
-Various cleanup

10-bit slave addressing is untested until I have a device that speaks
such.
