* renamed private members for more clear code
* registerExternalBufferID() method to obtain unique ID for withExternalBuffer()
* PICoutManipulators::PICoutStdStream enum for select stream (stdout or stderr)
* Constructors now accept optional stream
* piCerr and piCerrObj macros
PIDir::temporary() moved to "mkdtemp"
PILog:
* now 4 levels
* you can set max level
* Error writes to piCerr
* PIThread::~PIThread() now unregister itself from introspection, if terminates than show warning
* PISystemMonitor now correctly stops
* PIPeer now can correctly stopAndWait
* PIPeer::destroy(), protected method for close all eths and threads
* new PIINTROSPECTION_STOP macro
* Introspection now can be correctly stopped by macro, more safety
ClientServer:
* ClientBase::close() stop and disconnect channel
* Server clients clean-up now event-based
* No warnings on client destructor
maybe fix hang on PIEthernet::interrupt()
replace piLetobe with piChangeEndian:
* piChangeEndianBinary
* piChangeBinary
* piChangedBinary
PIDiagnostics::start now accept PISystemTime instead of number
add PITimer::start(PISystemTime, std::function<void()>) overload
in almost all methods removed timeouts in milliseconds, replaced to PISystemTime
PITimer rewrite, remove internal impl, now only thread implementation, API similar to PIThread
PITimer API no longer pass void*
PIPeer, PIConnection improved stability on reinit and exit
PISystemTime new methods
pisd now exit without hanging
