* dtable.cc (handle_to_fn): Add check for correct installation_key string in object name for pipes and ttys. * external.cc (cygwin_internal): Add CW_GET_INSTKEY to allow fetching the installation_key from cygserver. * fhandler_fifo.cc (fhandler_fifo::fifo_name): Add installation_key to fifo name. * globals.cc: Include cygprops.h. (_RDATA): Move slightly and add comment. (cygwin_props): Define. * mount.cc (mount_info::init): Accommodate the fact that installation_root is now a global variable in DLL common shared memory, rather than a member of cygwin_shared. * pipe.cc (fhandler_pipe::create_selectable): Add installation_key to pipe name. * shared.cc (installation_root): Define here for storage in DLL common shared memory. (installation_key): Ditto. (installation_key_buf): Ditto. (init_installation_root): Convert from shared_info method to ordinary function. Add initializing installation_key. Invalidate installation_key depending of value of disable_key property. Add comment to explain. (get_shared_parent_dir): Add installation_key to directory name. (get_session_parent_dir): Ditto. (shared_info::initialize): Move call to init_installation_root from here... (memory_init): ...to here. Add debug output to print installation root and installation key. Add comment to explain why. * shared_info.h (SHARED_INFO_CB): Recalculate. (CURR_SHARED_MAGIC): Ditto. (class shared_info): Remove definition of installation_root and declaration of init_installation_root. (init_installation_root): Declare. (installation_root): Declare. (installation_key): Declare. * uinfo.cc (pwdgrp::load): Accommodate the fact that installation_root is now a global variable in DLL common shared memory. * include/cygwin/version.h: Bump API minor number.
