2. not require --results-dir to be present
3. if invoked with .spec file, print just that file (that broke long time ago I think)

Summary:
This diff changes the toplevel 'infer' executable from the current
python script to an OCaml binary. Currently this executable only parses
command line arguments, sets up environment variables, and invokes the
existing python script. This improves infer's command-line and
configuration interface, since passing arguments to the frontends or
backend no longer requires manually setting environment variables, and
arguments for the toplevel can now also be specified in .inferconfig.
Simplification and migration of functionality from the python script is
left for the future.

Now that array types record only static - and therefore constant -
lengths, Sil typ and exp no longer need to be mutually recursive.
This diff:
- splits the recursion in the type definitions of typ and exp,
- splits the recursion in the comparison and pretty-printing
functions,
- and then refactors typ into a separate module.

Assume that std::vector::resize will always create nonempty vector. While this is clearly
wrong for resize(0), it removes many FPs for `resize(n)` calls, where value of `n` is unknown.
Without it, infer was thinking that `n` could be 0 and reported empty vector access.

Summary:
Array types where the length is not statically known were represented
using fresh variables. This diff:
- Makes array type length optional, reducing the amount of work needed
for renaming, substitution, and normalization.
- Revises uses of array length so that the length component of a
Tarray type represents only the statically determined constant
length of an array type, and the length component of a Sizeof
expression represents the dynamically determined length of an array
value.
- Restricts the type of static lengths from a general expression
(Sil.exp) to an integer (Sil.Int.t), enforcing that static types are
constant. This in particular ensures that types contain no
variables, and so are invariant under operations such as renaming
and substitution.
- Removes the type substitution and renaming functions typ_sub,
typ_normalize, and typ_captured_ren. Now that array type lengths
are constant integers, all of these functions are the identity.

Summary:
This diff extends Sizeof expressions with an optional expression for the
length of the final extensible array, if any. For example, sizeof a
simple array `sizeof(t[n])` is represented by (modulo subtyping info)
`Sizeof t (Some n)`, and sizeof a struct whose final member is an array
`sizeof(struct s {... t[n] f})` is represented by `Sizeof (struct s
{... t[n] f}) (Some n)`.
This is an intermediate step toward eliminating expressions from types,
the redundancy between the length in the types and in the sizeof
expressions will be eliminated later.

Summary:
Specs files can become stale and cause crashes if the serialized format
changes. It is unclear how to add the right dependencies to the
existing targets, so this patch just removes them. Perhaps when the
specs are built we should drop an empty file to time-stamp them, and add
a target that depends on e.g. InferAnalyze and produces that file, and
then add dependencies on it.

Summary:
Hardcoding `variable@` in Makefiles is Bad™ because it prevents the users from
overwriting them easily with `make variable="my custom value"`. The right way
to do it is thus:
```
variable = variable@
# then use $(variable) everywhere
```
This diff puts all the `variable = variable@` lines in Makefile.config.in, and
changes every occurrence of a `variable@` to `$(variable)` everywhere else.
I mostly automated generating this diff. Here are the steps I did:
- find out which `variable@`s we use:
find . -name 'Makefile*' -exec grep -e '@[^@ []\+@' -o -h \{\} \+ | sort | uniq > config_variables
- write this `replace.sh` script to replace every `variable@` with `$(variable)`:
```
#!/bin/sh
config_vars_file=$1
shift
for line in $(cat $config_vars_file); do
var=$(echo $line | tr -d @)
sed -i -e "s/$line/\$($var)/g" $@ > /dev/null
done
```
- run the script as such:
find . -name 'Makefile.*in' \( -not -wholename './Makefile.config.in' \) -exec ./replace.sh config_variables \{\} \+
- put all the `VARIABLE = VARIABLE@` lines in Makefile.config.in
- move all `Makefile.in` to `Makefile`, since they don't need to be generated by `./configure` anymore:
```
for i in $(find . -name 'Makefile.*in' \( -not -wholename './Makefile.config.in' \)); do \
rm $(dirname $i)/$(basename $i .in) && git mv $i $(dirname $i)/$(basename $i .in) ; \
done
```
- delete all Makefile except Makefile.config from configure.ac
- manually inspect and remove remaining instances of `VAR = $(VAR)` in makefiles, looking at the output of `git grep '^\(\w\+\) = $(\1)'`
