A generic interface miosix::ContextSwitchTimer has been added to the
kernel that can play the role of either periodic/aperiodic system timer.
Like other kernel interfaces, there should be provided a proper
implementation for cstimer.

Currently the only available implementation is done for cortexM4_stm32f
which is based on TIM2 timer. Although the implementation is an
aperiodic timer, it is set to act like a periodic timer with T=1ms.

In this subproject, an 64 bit apriodic timer is created based on
TIM2 in which the overflow is managed automatically and the user
is able to set checkpoints (in terms of timer ticks) to fire IRQ.

An expected usecase is the use this driver as the context switch
tool for the kernel.
There might be some errors in which overflows/checkpoints are not
managed correctly that will be OK asap.

Some commits ago when adding the polinode board and switching to C++11 the Makefile.inc was changed, but the MAKEFILE_VERSION was mistakenly not incremented, which caused issues using git out-of-tree projects. Incrementing version now, you should update your Makefile.inc if you are running a git out-of-tree (i.e. you are using submodules)

Improved Makefile path referencing to always use relative paths, as using absolute ones fails when the absolute path contains spaces.

Added support for out of git tree projects to allow having Miosix as a git submodule of another project

  doing make clean on an already clean directory, no errors are reported
- Added DMA RX for USART1 un STM32Serial. Also fixed bugs on stm32f1.

First process running in testing branch. Problem was the new context save code accounting for floating point registers. Still much work to do.
