Summary:
If an access path rooted in some parameter `p` is accessed outside of synchronizaton, but `p` is owned by the caller, then we should not warn.
We will implement this by separating writes into "conditional" (safe if a certain parameter is owned by the caller" and "unconditional" (safe only if the caller synchronizes appropriately).
This diff just introduces the map type for conditional writes and changes the transfer functions accordingly.
We'll actually use the map in a follow-up.

1. One call to `Core.Std.String.slice` was wrong and caused the program to crash, and
2. The crash was silently ignored because the error code of uncaught OCaml
exceptions was the same as `CheckCopyright.copyright_malformed_exit_code` (=2)
Address both issues. Also build CheckCopyright with debug options.

Summary:
This makes it more obvious why infer would force a path to be absolute since we
base that decision on the resolved path. For instance:
```
$ mkdir foo
$ cd foo
$ ln -s ../examples goo
$ infer -- clang -c goo/hello.c
[...]
/home/jul/infer/examples/hello.c:14: error: NULL_DEREFERENCE
```
We see that the path is outside of the current directory clearly, whereas
before infer would report on "goo/hello.c".

Summary:
`make byte` will populate infer/bin/ with bytecode version of each executable,
plus infer/bin/infer.byte (used to remember which of the native or byte
executables have been built most recently). `make infer` now also creates
infer/bin/infer.native, so that we're sure to replace the executables with
native/byte versions as appropriate.
This is to make debugging a tad easier:
make byte
ledit ocamldebug $(which infer) <infer args>
Whereas previously one had to:
make -C infer/src byte
ledit ocamldebug infer/_build/infer/backend/infer.byte <infer args>

Similar to marking classes ThreadConfined, we want to support marking fields as well.

Summary:
Currently, if we don't find `-d` or `-classes_out` on the command line then we
tell javac to redirect the compiled classes in some other directory, by default
the initial working directory. But we don't detect when these arguments are
hidden inside files (`foo` arguments on the javac command line) so the
heuristic was incomplete. Look inside these files to better tell whether we need
to make up an output directory or not.

- Generate infer genrule only if the `java_library` has `srcs`, otherwise there is nothing to analyze

Also no need to distinguish anymore between stmt and decl in the
semantics of EX and EF.
Moreover, the diff de-couple hard-coded checkers (eg checks on component kit)
from those checkers parsed in the .al files.
