Change pid_to_str to return std::string
...
Currently the target pid_to_str method returns a const char *, so many
implementations have a static buffer that they update. This patch
changes these methods to return a std::string instead. I think this
is cleaner and avoids possible gotchas when calling pid_to_str on
different ptids in a single statement. (Though no such calls exist
currently.)
This also updates various helper functions, and the gdbarch pid_to_str
methods.
I also made a best effort to fix all the callers, but I can't build
some of the *-nat.c files.
Tested by the buildbot.
