The CommandExecutor helper class can execute shell commands in blocking and non-blocking mode
This class is able to execute processes by using the Linux popen call. It also has the capability of writing
the read output of a process into a provided ring buffer.
The executor works by first loading the command which should be executed and specifying whether
it should be executed blocking or non-blocking. After that, execution can be started with the execute call.
Using non-blocking mode allows to execute commands which might take a longer time in the background,
and allowing the user thread to check completion status with the check function
Moved to HAL like requested in code review and unit tested with failing commands as well.
Also, Linux HAL components are compiled by default now unless explicitely disabled.
1. The type correction was merged as part of
#7 in the
EIVE project. Quotation of PR
definition of getSpiParameters is `void getSpiParameters(spi::SpiModes& spiMode, uint32_t& spiSpeed, UncommonParameters* parameters = nullptr) const;`.
Here, size_t spiSpeed is passed, which implicitely gets converted to a temporary, which can not be bound to uint32_t& and, at least in gcc 9.3.0, leads to a compiler error.
2. Allow flushing the UART buffers
