[commit] Deprecate remaining STREQ uses

[Michael Elizabeth Chastain]

My two cents:

(1) I don't like it when patches are chained to other work.
    ("You must do Y if you touch X".)  If fixing X is good,
    and it does not make Y _worse_, then I'm fine with X alone.
    I know this isn't gdb policy but it's my preference.
    One exception to this is copyright notices.

(2) The problem with cleaning up old code is that there's so much
    code which never gets tested.  That's a QA problem.  I would
    like to test more, and I've just recently gotten access to
    HP's test drive.
    
    But basically, I think we should be more aggressive about
    deprecating things.  If nobody submits test results for a platform
    to the gdb-testers group for a long time, then I would like to drop
    that platform.
