Note that Python does pass `--buck` to OCaml infer to make it aware that it is
running from within Buck, and the OCaml code uses that flag to trim infer-out
to only what's strictly necessary (and especially to remove non-deterministic
output that would mess with Buck's cache).

Summary:
Try and enforce the following rules:
- stderr is for updating the user about progress or errors
- Introduce Logging.progress that outputs to stderr, but honours --quiet
- Logging.stderr is as before
- Logging.out now prints to stderr (or to log files as before if set up) and
not stdout. If some information should go on stdout then the user should be
able to rely on it (ie, it's not just some progress message). For now only
the summary of the errors is printed on stdout by default.
- Logging.err* functions are gone. If the error is user-visible, it should be
Logging.stderr, or `failwith`. If not, go to the same log file as other
output, which personally I find much more convenient than having to dig through
2 log files every time I'm looking for some output.

Summary:
Introduce `infer-<command>` for each command, except for internal commands
(only `infer-clang` for now) which are not exported. Install these executables
(which are just symlinks to `infer`) on `make install`. The main executable
looks at the name it was invoked with to figure out if it should behave as a
particular command.
Get rid of `InferClang`, `InferAnalyze`, and `InferPrint`. As a bonus, we now
only need to build one executable: `infer`, which should be a few seconds
faster (less link time).
`InferAnalyze` is now `infer-analyze` and `InferPrint` is `infer-print`. To run
`InferClang`, use a symlink named `clang`, `clang++`, etc. to `infer`. There
are such symlinks available in "infer/lib/wrappers/" already.
I also noticed that the scripts in xcodebuild_wrappers/ don't seem useful
anymore, so use wrappers/ instead, as for `make`.

It's quite common to have collections of delegates. The collection itself is usually named like "delegatesHash", "delegatesStorage" or simply "delegates". Obviously, there is common part in all these cases, but currently you're excluding property only if it contains "queue".

Summary: The Buck integration assumes that the output jar file of all the dependency targets are available locally in order to retrieve the analysis from these targets.

Summary:
This replaces the previous integration written in Python, which consisted in 1)
run the mvn command and parse its output to locate "directories containing
source files", 2) run on files named "*.java" in these directories. This meant
we had to run javac twice on each source file, and more importantly this
mechanism of finding source files was very fragile. In fact, I could not make
it work on several mvn projects I tried.
The new integration is based on parsing "pom.xml" to add an "infer-capture"
profile which instructs mvn to run `/path/to/infer` instead of `javac`. We also
add this profile to each maven submodule.
Users can specify an "infer-capture" profile themselves if the default one
doesn't work; in that case we don't inject our own "infer-capture" profile.
