build: move library related code to lib/ Cleanup main Makefile and remove all library related code to lib/ to better support the increasing number of libraries and to keep the main Makefile clean from library dependencies.

newlib: add support for nano-formatted-io If newlib is configured with --enable-newlib-nano-formatted-io, floating-point support is split out of the formatted I/O code into weak functions which are not linked by default. This leads to a smaller code by about 16~20k when using newlib "printf" and/or "sscanf" but not using floating point I/O. Programs that need floating-point I/O support must explicitly request linking of one or both of the floating-point functions: _printf_float or _scanf_float. This can be done at link time using the -u option which can be passed to either gcc or ld. Implemented via new configuration options: CONFIG_NEWLIB_LIBC_FLOAT_PRINTF CONFIG_NEWLIB_LIBC_FLOAT_SCANF Change-Id: I57f9d9f02e6d21d6011d14de7153b1d3ba6f6e32 Signed-off-by: Juro Bystricky <juro.bystricky@intel.com>

lib: Introduce the CoAP implementation for Zephyr This is a CoAP implementation tailored for Zephyr's requirements, it tries to use memory predictably by exposing its control structures to the user (so the user only pays for the features that are used) and having a lightweight packet representation (the trade-off is that adding options is not as efficient as it could be, if there were more information available).
