Now platform_type is no longer global it tracks with board instance
so that platform and sub-platform can report different types.

This also means arm subplatforms can work and removes a plat == NULL check
which will never be true if -DUSBPLAT=ON

All files in sysfs are 4K minimum so allocate a 4k buffer to hold the result -
even if it'll never be that big

Avoids on some platforms where when setting a mux will set it low when
it wouldn't be safe to.

Instead of plain char* to avoid need to malloc and do all the needed
error checking needed that goes along with that.

It's already the case for rpi & MMAX but it should be noted that on 1 indexed
boards gpio_count should be +1

test was adding board gpio_count to pin so that 0 would use the info for pin 14

mraa_init() will now:
- print user name and EUID of the process instead of UID,
- print full platform text name in addition to numeric type,
- return, log and print an error if started by non-root user

Doing so breaks galileo gen2 (gpio2) and others. Failing early is rather
pointless in any case so we may as well attempt the write, muxes do not
neccesarily have directions that work

Instead of trying to have an implementation that covers most platforms
Leave all mmap up to platform definition. Through function pointers.
gpio_mmap_setup sets up the mmap
Within the internal gpio context struct two more function pointers now
exist mmap_read & mmap_write. They exist there so each context can its
own function for handling a write and read.
