Summary:
Merging the results directories of targets on buck projects involved creating symbolic links into buck-out.
The bulk of files are .attr files: one per procedure. Creating these links can be a bottleneck, and the merge phase can be slower than the analysis phases on projects with many procedures.
This diff introduces multilinks to speed up merge.
A multilink is a file `multilink.txt` containing a sequence of paths
```
path/to/file1.ext
path/to/file2.ext
...
```
A multilink file is a compact way to represent a link for each entry.
This diff creates a multilink file for each `attributes/dir` directory, instead of one symbolic link for each file.

Summary:
This also adds `-a compile` support to `InferClang`. This is needed for the
`xcodebuild` integration, which is hard to fold into the same binary as the
rest.

Summary:
During the development/debugging of AST checks, it will be possible to emit dotty graphs with a representation of the evaluation of formulas.
The formulas, expressed using the notation of CTL (https://en.wikipedia.org/wiki/Computation_tree_logic) are represented in a graph alongside the current ast-node and their final evaluation result (green for true, red for false)
To get the dotty graph, run infer with the `--debug` flag

Summary:
This is needed for later: InferClang will no longer be started once for each
source file to be analysed. Instead, it will be called to analyse several files
at once, and will analyse them one by one. Thus, `clang_lang` and `source_file`
are moved to `cFrontend_config` as references.
The biggest change this entailed was the new logging infrastructure, which was
depending on `Config.source_file`. This diff moves the logic entirely to
`Logging`, and changes the API so that executables wishing to log into files
have to set it up using `Logging.set_log_file_identifier`. This can be called
several times during the execution, allowing to dynamically change the log file
(eg, when analysing several source files one by one!).

Summary:
Move most of common dependencies out of backend/ into base/
Diff doesn't change any code and hence files in base/ may still depend on
code outside of base/. There will be followup diff cleaning those up.
There are also files that maybe should be in common/ but haven't been moved there yet.
