Summary:
We can fill the gaps in the trace now: they correspond to processes waiting on
pipes. This suggests a more efficient protocol would help perf, at least on the
small example I tried. Anyhow, it shows it's useful to trace pipe operations.
Some small gaps remain but they look like they could be explained by rounding errors.

Summary:
The model for `getcwd` assumes the first argument should be non-null when in fact a NULL pointer is legitimate and results in allocation:
> As an extension to the POSIX.1-2001 standard, glibc's getcwd() allocates the buffer dynamically using mal‐
> loc(3) if buf is NULL. In this case, the allocated buffer has the length size unless size is zero, when buf
> is allocated as big as necessary. The caller should free(3) the returned buffer.
I suggest this glibc extension be used for the getcwd model to reduce false positives.

Summary:
For some unexplained reason, some of the functions registered in the Epilogues would sometimes be executed several times. I could not figure out why.
This diff fixes that, but also has more explainable benefits:
- Do not run epilogues registered in the parent in the children. Previously it
would do so, but probably only if the children registered some epilogue given
that `at_exit` must be called again once on the child (but the value of the ref
in `Pervasives` would not have been reset).
- Unified behaviour for early and late epilogues given that we now handle both of these directly
We already have all the control needed to run epilogues when needed: we know
when infer exits, and we know when children processes exit.

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:
Litho uses an idiom as follows. `Component.Builder` has an abstract method `T getThis()` which is supposed to be implemented as `{return this;}`.
I believe the reason it's there is to have covariant return types in subclasses, though this doesn't really matter.
We don't do dynamic dispatch, so instead of summarising `getThis` as having a return ownership of `OwnedIf({ 0 })` we just return `Unowned`.
This is generating many false positives, which are really hard to debug.
Here I'm special-casing any abstract method whose return type is equal to that of it's only argument, to return conditional ownership.
