common/ptid.h: Mention that process_stratum targets should prefer ptid.lwp.
It's best that we standardize on process_stratum targets using the
ptid.lwp field to store thread ids. The idea being leave the ptid.tid
field free for any thread_stratum target that might want to sit on
top. This patch adds a comment in that direction to struct ptid's
definition.
