Summary:
`JavaSplitName` is used to represent Java types (in `Procname` in particular). The type itself is a pair of string (an optional package qualifier) and a "type name" (the quotes are there because it may contain array qualifiers).
For example `java.lang.Object[][]` should be represented as
```
{package=Some "java.lang"; typename="Object[][]"}
```
The constructor `make` was misused to construct instead types such as
```
{package=None; typename="java.lang.Object[][]"}`
```
This is evident when we print the return type of a `Procname` non-verbosely (the default), but we still see the package qualifier.
Obviously this is not just a pretty-printing bug, the values were themselves wrong.
The fix is to use the `of_string` constructor which will parse the package and separate it correctly. Another bug (in response to this one) had to be fixed in `Procname.is_vararg` to maintain behaviour in Nullsafe and Quandary.

Summary:
Old versions of sawja/javalib got the line numbers slightly wrong. The workaround was to do a regexp search in the source file for the right line.
My understanding is that this is no longer necessary. This diff removes it.

Summary:
Goal of the stack: deprecate the `--analyzer` option in favour of turning
individual features on and off. This option is a mess: some of the options are
now subcommands (compile, capture), others are aliases (infer and checkers),
and they can all be replicated using some straightforward combination of other
options.
This diff: stop using `--analyzer` in tests. It's mostly `checkers` everywhere,
which is already the default. `linters` becomes `--no-capture --linters-only`.
`infer` is supposed to be `checkers` already. `crashcontext` is
`--crashcontext-only`.

Summary:
It's useful to test that the bucket a given error is classified as doesn't
change over time without notice.
This records the bucket for *all* the tests, even though some never produce a
bucket. This is to be on the safe size instead of risking to forget adding the
bucket information when the test changes, or when copy/pasting from a test that
doesn't have buckets to one that does.
The implementation is pretty crude: it greps the beginning of the qualifier
string for a `[bucket]`.

Summary:
The abstract interpreter tried to handle exceptional control-flow by propagating the *pre* of a block that threw an exception rather than the *post*.
This was a half-measure that isn't correct when an exception-throwing instruction isn't in the middle of a block.
The handling of exceptions wasn't actually used anywhere and was leading to further hacks in `ProcCfg`, so let's get rid of it.

Summary:
At the moment, Java and Clang sources/sinks live in the same inferconfig entry.
If we try to parse a Java procedure that happens to be an invalid Clang qualified name (e.g., `MyClass.<init>`),
parsing will crash.
As a temporary fix, throw an exception and catch it instead.
In the future, we can avoid this by requiring that JSON source/sink specifications to indicate the language.

Summary: This will avoid collisions when the inner classes are implementing the same methods. For example, the previous version of the bug hash could conflate the issues when several annonymous inner classes are implementing the same method, e.g. a annonymous subclass of `Runnable` implementing `run()`.

Summary:
Simpler bug hash that is more independent of the underlying analysis. This now computes the hash based on:
- the bug type.
- the base filename: i.e for my/source/File.java, just keep File.java. So the hash will not change when moving files around.
- the simple method name: i.e. without package information and list of parameters. So changing the list of parameters will not affect the bug hash.
- the error message were the line numbers have been removed. So moving code or reformatting will not affect the hash.

In a summary, you never want to see a trace where non-footprint sources flow to a sink.
Such a trace is useless because nothing the caller does can make more data flow into that sink.

1. Mark some Makefile targets as depending on `MAKEFILE_LIST` so they get rebuilt on Makefile changes
2. Do not show boolean options with no documentation in the man pages (like we do for other option types).
3. Default to Lazy dynamic dispatch for the checkers.
4. In the tests, use `--<checker>-only` instead of relying on `--no-default-checkers`
5. `--no-filtering` is redundant if `--debug-exceptions` is passed

Summary:
Since D5381239, infer is careful not to delete directories that do not "look
like" results directories on startup, in case the user passed, eg, `-o /`.
In our repo, lots of results dir are created by build/test of infer, and when
the version of infer changes and the expected contents of results directories
change then it might start refusing to delete the results directories created
with another version of infer.
Add an option to force infer to delete the results directory no matter how
dodgy it looks, and use it in our repo by adding the option in every
.inferconfig.
