Remove unused NormalizedInstruction::funcName and associated machinery

I was digging into how annotate works and noticed that we go to all
this trouble to set funcName but nothing reads it. Getting rid of it simplifies
a lot of related code.

Test http headers containing "Expect: 100-continue"

API endpoints are frequently called with 100-continue so we
want to make sure they work.  This would have caught a recent bug
introduced in our libevent implementation.

change the debugger to use .ini files

In my quest to kill `.hdf` files these have to go. The weirdest thing was writing out all the colors to the file just incase someone wrote a node to reference them, instead I just put them in the docs.

There isn't an INI serializer built into php, but the format was simple enough to do with strings.

Remove dead code: simplifyPrint

I imagine this is a holdover from a previous time when we had a single
polymorphic Print opcode. Nowadays it's impossible for that optimization
to kick in because the three Print* opcodes are monomorphic: if their
src were Null, the IR wouldn't typecheck.
