Summary:
When looking at large CFGs, at least in `xdot`, it's often difficult to find
the procedure you're looking for. Sorting the proc names puts them in
alphabetical order, which makes searching one procedure easier.

[This is a stepping stone before moving the specs data to sqlite.]
Previously, things worked like this (ignore ObjC):
1. capture & analyse C models
2. capture & analyse C++ models
3. copy C *.specs files to lib/specs/
4. copy C++ *.specs files to lib/specs/
Now it works like this:
1. capture C models
2. capture C++ models
3. analyse both together
4. install *.specs files to lib/specs

It works now. Jumping to definition or calling merlin-document on files from
opam libraries doesn't seem to work when several libraries used by infer define
the same module (e.g. string.ml exists in ocaml lib, core_kernel, and base).

Given a difference between two files, return the relevant lines in the new file; a line is relevant when a change took place in it, or nearby. To generate a valid input for this parser, use unix-diff command with the following formatter arguments:

Summary:
We were using the "filename" as the key because it's (kinda) unique *and* human
readable, but with the `infer explore --procedures` interface we don't really
need the human readable part anymore, so we can just use the OCaml marshalling
of the pname as the key. The human-readable version (sans unique-fying hash) is
now another column in the table, used to match procedure names in
`--procedures-filter`.

Summary:
Add a `--procedures` option to `infer explore` to print information about the
procedures captured by infer. More precisely, `infer explore --procedures` will
print each row of the "procedures" table in the results database. A new
`--procedures-filter` controls which procedures to print information about, and
there is one flag per column in the db too to print more or less options about
each procedure (in particular, we can now print attributes), with some defaults.

Summary:
Run with `SHELL = bash -e -u -o pipefail` to catch many kinds of failures. We
were silently failing during `make install` because of some missing escaping,
and the failure was hidden because it was happening inside a bash `for` loop.
This fixes the escaping issue and makes sure such issues will result in an
error as of now.
Also removes dangerous `find -exec` instances: `find` will `exit 0` event if
some commands failed.

Summary:
Try to skip running even `clang -###` when we know there's nothing to capture
in the clang command. Do that by recording in the `ClangCommand.t` whether the
command is pre- or post-running `clang -###`, and apply slightly different
filters in each case. In particular, the filter has to let in more commands
than necessary pre-`clang -###` because the flags are not normalised at that
point.
Also regard `-x cuda` commands as unsupported.

This is unused, but the logic for keeping its value up to date was still alive

I don't know that making use of this flag would be easy: we could just use it
in `Ondemand.should_analyze`, but it would be unsound because a procedure might
need to be re-analysed becauese its dependencies have changed. Since there's
not code to deal with that currently I think it's best to remove it and
re-introduce it when we have some idea how to use it.
