include/nuttx/i2c/i2c_master.h: Rename I2C_M_NORESTART to I2C_M_NOSTART since it may be used in other contexts than a repeated start. Add comments to clarilfy setup for repeated start.

include/nuttx/i2c/i2c_master.h: Add a definition to distinguish a new START of messages from a repeated start. No lower-half I2C drivers actually implement this new flag bit, however. drivers/i2c/i2c_writeread.c: Use new repeated START definition where appopriated. Other: Some cosmetic changes, updates to README files, etc.

...
Feature pca9540bdp i2cmultiplexer
* Implement common i2c multiplexer abstraction to be reused by i2c multiplexer devices. Provide common interface with transfer and reset calls to set up virtual i2c busses.
* Remove i2cmux_lower_half.c and headers, will be implemented by each mux driver
* Implement PCA9540BDP I2C multiplexer lower half which uses the common i2c mux abstraction
* Remove application interface and implement common i2c functions
* Remove application interface from pca driver and implement common i2c functions directly in the pca driver
* Use i2cerr
