lldb support seems pretty broken in lldb-300.5.27.3

[richo]

So far what I've deduced:

I can get voltron to work if I:

• start lldb
• load voltron
• start voltron
• attach a bunch of viewers
• manually call voltron update
• Do whatever I'm doing in lldb
• manually call voltron update every time I want the viewer to update.

I get a barf in get_registers that crashes lldb if it's run in a hook, but if you run voltron update from the debugger it dumps a stack trace. It looks like GetRegisters is returning an empty set.

tl;dr I'm happy to work on this but missing a bunch of domain knowledge about how lldb's interface works/how voltron is bound to it. If you're free, wanna give me a primer at some point?

Some more info, I've been using it all morning, basically doing the voltron update dance by hand.

Since I added a stack viewer, I get this super helpful error out of lldb everytime inferior execution stops:

error: Aborting reading of commands after command #0: 'voltron update' failed with <unknown error>.

Fixed with beer/hackathon with richo
