Summary:
First step towards a global analysis. A new command line flag activates the step in `Driver`.
The whole-program analysis is a simple, quadratic (inefficient-as-yet), iteration over all domain elements. However, it is restricted to those elements that are explicitly scheduled to run.

Summary:
I observed a bug in incremental analysis for thread safety analysis, where a thread safety violation was not being reported because the folder `racerd` was not being cleaned. This meant that the violation was determined to be a preexisting issue when it was actually an introduced issue.
This method can be used to fix this problem by cleaning the `racerd` folder. It also cleans the `captured` folder, I've done this following the original version of the method (see D16602417).
I'm not sure if the `captured` folder is used; it wasn't used in the tests I did. Thoughts about this?

Summary:
Implementation of write-serializer for Sqlite. Points of note:
- A Unix socket is used for communication. This avoids buffer-size limitations, as the objects we send for writing may exceed said limits.
- No daemon is used if running under buck or in genrule mode, as this usually means a single-threaded job capturing into the DB.
- When the daemon is running, read-only access is *not* enforced for other processes. This makes starting and stopping the daemon during Infer execution easier and more robust. In WAL mode this should not have any effect on performance.
- This version is not economical with connections, it uses one per query, todo.

Summary:
Write contention is becoming a problem in parallel capture (eg when make runs with high parallelism) or when analysis writes CFGs to the DB in parallel (eg when analysing blocks in ObC). This is believed to lead to BUSY errors in Sqlite.
This is step 1 of a process where all writes are cordoned-off in one module, and fixing the interface for that module.

Summary:
It's not being worked on and is not in a state where it works.
It would probably better to write this as a script of some kind or else
resurrect this subcommand in a form where it behaves more like a script,
ie fork/execs infer analyses instead of having them be function calls
(but then it might as well *be* a script as it would likely be more
flexible).
In any case...

Summary:
Move genrule capture integration logic from shell to OCaml.
Also, stop relying on side-effects of buck compilation for constructing the infer-deps.txt file used for merging. Now this is obtained by passing `--show-output` to buck, which spits out the `buck-out` output paths to the targets we asked to build.

Summary:
- Rather than passing a directory name to PerfStats reporting api to write the stats to, and then determining the EventLogger `stats_type` from that dirname, there is now a `stats_type` type in PerfStats, and the directory name and EventLogger tag is automatically determined from that type after it is passed to the API
- This allows us to determine whether we're in capture mode or linters mode dynamically from PerfStats itself, and use the appropriate tag when creating an event
