Skip to GDB version string on init
Skip to GDB version string when initializing debugger. This allows to use ~/.gdbinit file.
Initial problem comes from the fact that if ~/.gdbinit contains following string: skip -gfi /usr/include/c++/*
current gdb integration returns error.
It expects first gdb output to be something with gdb version but in case of this string it will be:
File(s) /usr/include/c++/* will be skipped when stepping.
