conjunction with older binaries.
(environ_init): Ditto.
* external.cc (get_cygdrive_info): New function.
* external.cc (get_cygdrive_prefixes): Change to use get_cygdrive_info but toss
the user and system flags.
* external.cc (cygwin_internal): Add new CW_GET_CYGDRIVE_INFO case.
* path.cc (mount_info::get_cygdrive_prefixes): Remove method.
* path.cc (mount_info::get_cygdrive_info): New method.  Actually,
get_cygdrive_info is really an enhanced version of get_cygdrive_prefixes
renamed to get_cygdrive_info that also gets the user and system flags.
* shared_info.h (get_cygdrive_prefixes): Remove method.
* shared_info.h (get_cygdrive_info): New method.
* include/cygwin/version.h: Bump minor API version due to adding
CW_GET_CYGDRIVE_INFO to cygwin_internal.
* include/sys/cygwin.h (cygwin_getinfo_types): Add CW_GET_CYGDRIVE_INFO.
