Description
Handle MSP properly and enlarge lwip tcp thread stacksize.
Set MSP in assembly block before jumping to the real platform startup code to avoid
redundant SP push/pop in prologue and epilogue. GCC does that when sibling code optimization is turned off which unfortunately happens under debug profile.
Also enlarge lwip tcp thread stacksize to reserve extra head room for GCC debug profile.
