Summary:
When a deprecated option is found in .inferconfig, we change it to `--<long>`
on the command line, but that string can be empty. Plumb things through so that
some non-empty string is selected in that case.

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.

Previously we wouldn't flush the formatter hence the error message would
generally not make it to the log file. Add the backtrace too, although only the
first few lines appear for some reason...

Summary:
First version of differential for costs, based on polynomial's degree's variation. The rule is very simple:
For a given polynomial that is available before and after a diff, `if degree_before > degree_after`, then the issue becomes `fixed`. Instead, `if degree_before < degree_after`, then the issue becomes `introduced`.

Summary: Buck is allowing compiler commands with no source files and skipping them when using the in-memory complier mode. However, those commands are not skipped when using an external compiler. Simulating this behavior at the level of Infer.
