Summary:
:
New flag (equivalent to --clang-biniou-file) to pass in AST to
frontend.
Passing in json files has the big advantage of emitting line numbers
on frontend AST errors.

Summary:
Output summaries in json format, so that other tools can exploit the
results of infer without having to be written inside infer itself.
For now the json for a summary is just one line saying "opaque" :)
Set up the infra to generate (yo)json automatically using
ppx_yojson_conv. See it in action in the next diff.

Summary:
- output the "menu" of the interactive mode on stderr instead of stdout
so that we can pipe the results, eg
`infer debug --procedures --procedures-summary | cat`
This will be more useful when we add an option to output json, as
otherwise the menu pollutes the json.
- Allow "--select" to work for infer-debug too:
`infer debug --procedures --procedures-summary --select 0`

Summary:
I wanted to change the default to "callgraph" but that created issues in
our tests, introducing flaky behaviours and even a failure due to trying
to run the pre-analysis multiple times (not 100% sure it was related).
Instead, document the various options and put the option in the analysis
manual so users can choose.

Summary:
Take another page from the Incorrectness Logic book and refrain from reporting issues on paths unless we know for sure that this path will be taken.
Previously, we would report on paths that are merely *not impossible*. This goes very far in the other direction, so it's possible we'll want to go back to some sort of middle ground. Or maybe not. See the changes in the tests to get a sense of what we're missing.

Summary:
This diff adds a new experimental checker for detecting size of objects in autorelease pool in ObjC. The basic mechanism is almost the same with the previous cost calculation:
* Autorelease pool size is increased at explicit `autorelease` call
* Autorelease pool size is set as zero by the `autoreleasepool` block.
While it only supports the explicit calls as of now, we will extend the checker to handle more cases in the following diffs.

This diff extends the cost_item json format to print the autoreleasepool_size field. Not yet, there
is no semantics for that code kind, so the results will always be zero with no traces.

Summary:
This diff adds a prototype of a new checker that collects config checkings between markers.
Basically, what the checker is doing is a taint analysis.
* Taint source: function calls of "marker start"
* Taint sink: function calls of config checking
* Taint remove: function calls of "marker end"
By the taint analysis, the analysis results will say that which taints can reach to the sink. In other words, which marker ID that has been started can reach to the config checks, before marker's ending.
I am separating the diff into three steps:
(1/3) Add basic abstract semantics
(2/3) Add trace information
(3/3) Add reporting with test examples
