[FYI] Make remote.c ptid constants "const"
Commit Message
This changes magic_null_ptid, not_sent_ptid, and any_thread_ptid to be
"const". This is a minor improvement that makes it so these can't be
accidentally modified.
Tested by rebuilding. I'm checking this in.

* remote.c (magic_null_ptid, not_sent_ptid, any_thread_ptid): Now
const. Add initializers.
(_initialize_remote): Don't initialize ptid globals.
