Summary:
Replaced by pulse. `--ownership` is now a deprecated form of `--pulse`.
The ownership checker is starting to give wrong answers due to changes in the
clang frontend, so it's better to remove it in favour of pulse.

Summary:
This is a simple checker that identifies inefficient uses of `keySet` iterator where (not only the key but also) the value is accessed via `get(key)`. It is more efficient to use `entrySet` iterator which already returns both key-value pairs. This optimization would get rid of many extra lookups which can be expensive.
We simply traverse the CFG starting from the loop head upwards and pick up the map that is iterated over. Then, we check in the loop nodes if there is a call to `get(...)` over this map. If, so we report.

Summary:
Replace `$(u,...)` with `$(i,...)` since `$(u,...)` doesn't exist.
Cmdliner was emitting a warning at runtime:
cmdliner error: Unknown cmdliner markup $(u,...) in "Specify classes where the destructor should be ignored when computing liveness. In other words, assignement to variables of these types (or common wrappers around these types such as $(u,unique_ptr<type>)) will count as dead stores when the variables are not read explicitly by the program. (default: $(i,[]))"

Summary:
Add an option to specify some classes that we really want to warn about
with the liveness checker, even when they appear used because of the
implicit destructor call inserted by the compiler.

Summary:
New analysis in foetal form to detect invalid use of C++ objects after their
lifetime has ended. For now it has:
- A domain consisting of a graph of abstract locations representing the heap, a map from program variables to abstract locations representing the stack, and a set of locations known to be invalid (their lifetime has ended)
- The heap graph is unfolded lazily when we resolve accesses to the heap down to an abstract location. When we traverse a memory location we check that it's not known to be invalid.
- A simple transfer function reads and updates the stack and heap in a rudimentary way for now
- C++ `delete` is modeled as adding the location that its argument resolves to to the set of invalid locations
- Also, the domain has a really crappy join and widening for now (see comments in the code)
With this we already pass most of the "use after delete" tests from the
Ownership checker. The ones we don't pass are only because we are missing
models.

Summary:
Keep `--analyzer` around for now for integrations that depend on it.
Also deprecate the `--infer-blacklist-path-regex`,
`--checkers-blacklist-path-regex`, etc. in favour of
`--report-blacklist-path-regex` which more accurately represents what these do
as of now.
Rely on the current subcommand instead of the analyzer where needed, as most of
the code already does.

Summary:
This allows infer devs to see the effects their changes have on the infer manuals.
Check in the manuals for each subcommand + the output of `--help-full` to get a
complete picture. If this is too annoying we can also check in only
`--help-full`.
