/* Search global state {{{2
*
* We only ever search under a global lock, so we can use (and reuse)
* some global data to reduce allocations made while searching.
*
* In short, we keep around arrays of results that we expand as needed
* (and never shrink).
*
* static_token_results: this is where we append the results for each
* token within a given desktop directory, as we handle it (which is
* a union of all matches for this term)
*
* static_search_results: this is where we build the complete results
* for a single directory (which is an intersection of the matches
* found for each term)
*
* static_total_results: this is where we build the complete results
* across all directories (which is a union of the matches found in
* each directory)
*
* The app_names that enter these tables are always pointer-unique (in
* the sense that string equality is the same as pointer equality).
* This can be guaranteed for two reasons:
*
* - we mask appids so that a given appid will only ever appear within
* the highest-precedence directory that contains it. We never
* return search results from a lower-level directory if a desktop
* file exists in a higher-level one.
*
* - within a given directory, the string is unique because it's the
* key in the hashtable of all app_ids for that directory.
*
* We perform a merging of the results in merge_token_results(). This
* works by ordering the two lists and moving through each of them (at
* the same time) looking for common elements, rejecting uncommon ones.
* "Order" here need not mean any particular thing, as long as it is
* some order. Because of the uniqueness of our strings, we can use
* pointer order. That's what's going on in compare_results() below.
