Summary:
Record per-location traces. Actually, that doesn't quite make sense as a
location can be accessed in many ways, so associate a trace to each
*edge* in the memory graph. For instance, when doing `x->f = *y`, we
want to take the history of the `<val of y> --*--> ..` edge, add "assigned
at location blah" to it and store this extended history to the edge
`<val of x> --f--> ..`.
Use this machinery to print nicer traces in `infer explore` and better
error messages too (include the last assignment, like biabduction
messages).

Summary:
When a lambda gets created, record the abstract addresses it captures, then
complain if we see some of them be invalidated before it is called.
Add a notion of "allocator" for reporting better messages. The messages are
still a bit sucky, will need to improve them more generally at some point.

Summary:
`make doc` will use `jbuilder` (which in turn uses `odoc`) to generate the
documentation for infer's modules. This is useful to browse the APIs of infer
and gives a more discoverable place to host more general documentation about
infer's internals.
Besides the actual plumbing necessary to generate the docs, this diff also
- Moves the various infer/src/*/README.md to index.mld files that make it to the generated docs
- Fixes some doc comments that would anger `ocamldoc`
Closes#435

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:
There's actually a nice separation between IR/, base/, istd/, and the rest of
infer, so they can be made into separate jbuilder libraries so that the
separation remains. This helps make sense of the infer codebase.
Also:
- move everything biabduction-related out of backend/ and into a new
biabduction/ directory. This clarifies the current situation where backend/
contains a mix of analysis-independent code (still there now), and
biabduction-specific code (moved to biabduction/).
- move everything from base/ that is not infer-specific into istd/, e.g. IList.ml
- kill unused `FbTraceCalls`
- A couple of files needed to move around to complete the separation of base/ and IR/
