Another hack to get over the stack issue. And a fix to show bash output inside
mintty.exe.

I still experienced crashes with the "updated hack".
So I did some experiments and came up with another hack which does
a few recursive function calls to get enough stack pages committed,
to not have guard pages hit inside some shared library calls.

After getting over the stack issues, mintty.exe still shows nothing
from the bash.exe process running inside.
This is because mintty relies on
NtQueryInformationFile(FilePipeLocalInformation)
returning the real value for ReadDataAvailable.

With these three patches applied I had e.g. bash.exe, mintty.exe,
ls.exe and script.exe working.
gdb.exe (because of some python initialisation) and python3.8.exe did not work.
