    evtr: initial implementation of a DSL
    
    libevtr:
    - abstract out the hash table, convert to using uintptr_t's
      internally
    - move a bunch of fields and most of the error logic from
      evtr to evtr_query
    - don't try to resolve format strings to id's and reject
      records that don't match early; this needs way more care
      now that we might want to interpret the format strings
    - start implementation of a minimal Domain Specific Language
    - add the ability to filter based on the event type
    - lots of fixes all around
    
    evtranalyze:
    - catch up w/ API changes in libevtr
    - add toy 'stats' command
