Refactor code to check for terminal sharing
This refactors the code to check for terminal sharing.
is_gdb_terminal is exported, and sharing_input_terminal_1 is renamed,
slightly refactored, and moved to posix-hdep.c. A new
Windows-specific implementation of this function is added to
mingw-hdep.c.
MSDN has a warning about GetConsoleProcessList
This API is not recommended and does not have a virtual terminal
equivalent. [...] Applications remoting via cross-platform
utilities and transports like SSH may not work as expected if
using this API.
However, we believe this isn't likely to be an issue for gdb.
