[PATCH v2] Fix type of startup_with_shell in gdbserver

Tue Oct 1 18:07:00 GMT 2019
startup_with_shell was changed to be of "bool" type, but I noticed
that the definition in gdbserver disagreed. This disagreement caused
some regressions on a big-endian machine.
This patch removes the redundant declaration and definition of
startup_with_shell and ensures that such clashes will be diagnosed.
This moves the declaration to common-inferior.h, and introduces a new
common-inferior.c, as suggested by Pedro.
