Core api concept (#144)
* add input debounce code from old fw

* exampl of input api

* change input API to get/release

* revert input API to read

* pointer instead of instance

* add input API description

* add display API

* rewrite display names

* migrate to valuemanager

* add LED API

* add closing brakets

* add sound api

* fix led api

* basic api

* rename API pages

* change pubsub implementation

* move FURI AC -> flapp, add valuemutex example, add valuemanager implementation

* pubsub usage example

* user led example

* update example

* simplify input

* add composed display

* add SPI/GPIO and CC1101 bus

* change cc1101 api

* spi api and devices

* spi api and devices

* move SPI to page, add GPIO

* not block pin open

* backlight API and more

* add minunit tests

* fix logging

* ignore unexisting time service on embedded targets

* fix warning, issue with printf

* Deprecate furi_open and furi_close (#167)

Rename existing furi_open and furi_close to deprecated version

* add exitcode

* migrate to printf

* indicate test by leds

* add testing description

* rename furi.h

* wip basic api

* add valuemutex, pubsub, split files

* add value expanders

* value mutex realization and tests

* valuemutex test added to makefile

* do not build unimplemented files

* fix build furmware target f2

* redesigned minunit tests to allow testing in separate files

* test file for valuemutex minunit testing

* minunit partial test valuemutex

* local cmsis_os2 mutex bindings

* implement furi open/create, tests

* migrate concurrent_access to ValueMutex

* add spi header

* Lib: add mlib submodule.
