We rely on driver-supplied information in mraa_spi_frequency(),
so let's be consistent.
Closes#132.

This could be generally useful and more specifically is a
prerequisite for issue #178.

The declaration seems to be misplaced compared to all other similar structs.
It's also a prerequisite for introducing the _replace hook for spi_lsbmode(),
per issue #178.

This stops the error code getting lost since -1 wraps around to 0xFF when cast
to a uint8_t. This fixes#146

This lets you access a spidev device directly without any checking in the style
of mraa_i2c_init_raw

syslog messages should be written as <module>: Message in order to increase
readability and usefulness

When using SPI, I prefer to not have to do malloc/free functions for each
transfer, so why not have a transfer function that you can pass in both
buffers. With my ILI9341 TFT display code that gave some perf wins, also more
of a win, you can pass in NULL for recv buffer and the underlying device driver
does not have to copy the data.

Syslog is now used for all error messages, return values in the code should be
used by programmers to see the status of the library/board and syslog can be
used to see quickly from a debugging perspective what has gone wrong. A few
cosmetics where improved as well as a mraa_set_log_level() call where the
syslog log mask can be set directly from libmraa.
