Summary:
Store model summaries in the `model_specs` database table instead of in spec files.
This table is populated when a new database is created by loading a dump of the `specs` table in the models database. This avoids the perf and reliability implications of ATTACHing the same, non-read-only models-DB by many processes.
- `BiabductionModels` is moved into `IR` so that `JsonReports` can access it.
- The binary `sqlite3` is now required on the host compiling infer.

The models are only for biabduction so try to make that clearer in the

Summary:
[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

Summary:
Saw these two types of errors before (but they're hard to reproduce locally) when building the models:
- `ERROR: Zip.Error("/mnt/btrfs/trunk-git-infer-739-1503054473/infer/bin/../lib/java/models.jar", "", "end of central directory not found, not a ZIP file")`. I think this means infer reads a partially-written models jar. We shouldn't try to load this in models mode.
- `install` would complain that the destination already exists. I think this can only happen if there's a race and the file gets created between when install first checks and when it tries to write to it.
This made me realise that the some of the models are computed in C and C++ mode
and we pick one computed spec arbitrarily. That sounds a bit dodgy but at least
now we do so in a non-racy way.

Summary:
Nuking the specs then building the models was not a great idea: the models do
not look at specs but only at some dummy marker files, eg
infer/lib/specs/c_models, so they don't necessarily realize that they need to
be rebuilt when the specs have been nuked!
One easy workaround would be to also delete the marker files, but then we would
*always* rebuild the models when building infer. Not good.
The solution here is to nuke the specs and marker files only when the clang
dependencies change, then rebuild all the models.

Summary:
It can be useful when debugging infer or the Makefiles themselves to see what
`make` is doing. Instead of editing Makefiles to remove `@` now you can `make
VERBOSE=1`.
This is just `git ls-files | grep -e Makefile -e '.*\.make' | xargs sed -e 's/^\t@/\t$(QUIET)/' -i`, and adding the definition of `QUIET` to Makefile.config.

Summary:
Turns out that swapping stdout and stderr using a temporary fd 3 was screwing
up with make's jobserver, who also uses fd 3!
Also, infer is partly to blame as it also calls `make`. Unsetting `MAKEFLAGS`
in infer tells `make` that the way infer calls `make` is independent from
parent `make` invocations.
Also, simplify the rules for direct tests and build system tests.

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)'`
