[PATCH 00/13] CTF dumper improvements, a lookup testsuite, and bugfixes

Pushed! I'll see about sending the top-level stuff out next (it's so
simple that it should be easy to get in before the next sync, and if we
*do* miss it, all that happens is that make check-libctf does nothing
for a bit: no harm).

(As usual, this works everywhere I can try it, with one exception I just
noticed: the new libctf-writable testsuite works on non-ELF platforms,
with tests that link to the newly-built libctf, but on a
cygwin-to-mingw64 cross in one of my cygwin64 installations -- but only
one -- I'm seeing very odd stuff that looks almost like a buffer overrun
in the dynamic linker: complaints that it can't find shared libraries
whose names are complete garbage. I've ignored that for now because
whatever it is it's not a libctf bug and shouldn't really hold up a
libctf testsuite finally landing for everyone else. So my apologies if
anyone sees ERROR or FAIL results in that situation.)
