Here are the latest patches.

The ChangeLog entries are screwy, I will clean them up before checkin.

I am only including the big main patch, plus the Ada patch.
The other patches haven't changed in recent rebases.

Built and regtested on x86-64 F15.

Relative to the previous patch, I:

* Removed expand_line_sal
* Removed validate_inexact_match
* Changed decode_all_digits to replicate the logic that used to be in
  expand_line_sal
* Removed decode_line_list and instead added a "flags" enum and 
  changed all callers
* Changed "info line" and "clear" to use "list mode"
