Summary:
First step in writing an analyzer that is meant to run only on Android core library implementation.
This will, when finished, compute the library entrypoints that may lead to a strict mode violation.
The normal analyzer will use those to statically flag strict mode violations in app code.
Strict Mode is an Android debug mode, where doing certain things (like disk read/write or network activity) on the UI thread will raise an exception. We want to statically catch these, as well as indirect versions (the UI thread takes a lock and another thread holding that lock calls a method that would be a strict mode violation).

Summary: We had a special case for fixing false positives on constexpr implicitly captured by lambdas. However, we do not report dead stores on constexpr anymore, hence, do not need the special case anymore. Moreover, the special case was not only capturing constexpr in lambdas, but also any variables which type had `const` (see new test `capture_const_bad` which was not being reported before this diff)

Summary:
It simplifies abstract memory instantiations of function calls. Now it instantiates callee memories by directly evaluating symbol paths, rather than constructing `subst_map`.
main changes are:
- no construction of `subst_map` and `trace_map`
- no symbol table in Inferbo's summary
- no `Symbol_not_found` exception (for when a required symbol was unavailable in `subst_map`)

Summary: We report dead store false positives in template arguments when constexpr is used. To remove the false positives, with the expense of some false negatives, we do not report dead stores on constexpr anymore.

Summary:
Lambdas can capture references to locals of the enclosing method as long as
they are not propagated outside the method. However to keep things simple
always allow them to capture locals of the enclosing method at the price of
some false negatives.

Summary: C++17 introduce guaranteed copy elision which omits constructor calls. In ownership analysis, we depended on these constructor calls to acquire ownership. In particular, when a method returns struct, previously, a constructor was used to acquire ownership. In this diff, we acquire ownership of the returned structs directly.

Summary:
When we see `pthread_create(..., ..., foo, ...)`, we want to call the function
`foo` to check that its precondition is met. The initial goal was to get rid
of the uncouth call to `Summary.get` when what we really want is to analyse
`foo` instead of just betting on the fact that it has been analysed already.
Besides switching to `Ondemand.analyze_proc_name`, this also changes the
matching of the function pointer in the arguments of `pthread_create()` to
detect the common case of a constant function name. I also added tests.
