Switch to using calloc on all calls to malloc where the memory isn't
initialized. For things like the mraa_board_t, not allocating all to zero
causes issues such as with the sub_platform member, where if that's not zero
mraa_get_platform_type will try to dereference a random memory location for the
sub_platform->platform_name, which can result in segmentation faults and other
issues.
Note that in some places where immediately after the malloc call is a copy
operation, there is no need for calloc, as all the memory gets overwritten
anyways, but in cases where there may or may not be memory written to (such as
in mraa_file_contains, with reading from a file), even though in most cases the
memory is overwritten, it could be the case that the read operation does
nothing, but the memory still has non-zero values, by virtue of the fact it
wasn't overwritten.

This patch adds support to 96boards. 96boards is an open platform
specification. This spec strandardizes the pins on the external
connectors like Low speed and High speed. Given these pins are standard
across multiple boards, I think adding a generic 96boards made sense to
me.
The idea behind adding this generic board file is to make mraa work on
most of the 96boards with minimal changes to board support in libmraa.
This patch adds support to the LS expansion connector which has got 12
gpio pins + 2 i2c + 1 spi and 2 uarts.
For now I have added Dragaon board DB401c support as part of this patch
and is tested.
More info about board @ https://www.96boards.org/products/ce/dragonboard410c/
Long term plan is to get all this configuration from the /sys and
populate the board specifics dynamically, which is bit easy with
96boards specs in-place.

NPM builds don't support cross compiling and will always compile for the host.
Binding.gyp now uses mraa_NPM_SRCS instead of mraa_LIB_SRCS_NOAUTO which
contains all platforms. Cmake now uses mraa_LIB_PLAT_SRCS_NOAUTO to provide all
the sources. NPM builds will build objects for all platforms reguardless of
space which does meann slightly bigger binaries.
