* update files
* fix Dialyzer warning
* unconditionally enable info fil
* clean-up inconsistencies
* use term_to_binary compression
* use try...catch instead of case...catch...of
* do not write build info file if the graph is unmodified
* store info file as <base_dir>/.rebarinfo
* properly support list of compile directives
* fix regressions:
- Fix a bug in handling of files to compile first.
- If a file that is depended upon itself depends on other files, make sure
those are compiled first. While at it, rename variables for correctness.

- Make sure that FirstFiles has no dupes and preserves the proper order.
- headers referenced via -include_lib() were not properly resolved to absolute
filenames
- .erl files found in sub dirs of src_dirs were not properly resolved to
absolute filenames
- restore support for "rebar help xref"
- update rebar.config.sample
- update 'help xref' string
- simplify new/changed functions by breaking out code or
using simpler syntax where applicable
* Allow the following predefined analyses :
undefined_function_calls, undefined_functions, locals_not_used,
exports_not_used, deprecated_function_calls, deprecated_functions
* Trap some possible errors in case module information is not
available
* ignore_xref works on all checks and can take {M,F,A} tuples.
(Automatic behaviour export suppression still only works on
exports_not_used)
The custom queries are configured in rebar.config via the tuple
{xref_queries, [{query(), query_result()},...]}. The implementation
passes the query() string to xref:q and compares the return value with
query_result(). It will result in an error if they do not match.
The following configuration, for example, is the same as running the
xref check undefined_function_calls. It additionally filters
ejabberd_logger:*_msg/4 from the result as these functions are generated
on execution by ejabberd and not available at compile time.
{xref_queries, [{"(XC - UC) || (XU - X - B -
(\"ejabberd_logger\":\".*_msg\"/\"4\"))",[]}]}.
This patch also modifies the build process of this package by running a
custom query instead of doing a diff against a static xref_warning file.
It is now possible to call rebar as:
rebar xref skip_app=Mod1,Mod2,...
This makes it easy to skip running xref on (e.g)
imported dependencies in your application.
The function rebar_utils:is_skipped_app/0 is added so
that other rebar commands may use it.
For parameterized modules, the beam code will have a compiler
generated new/1 and instance/1 function.
If while checking the beam, xref detects one of those is unused, the
rebars xref wrapper will try to find the location of the definition of
that function in the source code for the module (to give a more
specific warning to the user). Since the function was generated by the
compiler it does not actually exist in the source, and rebar crashes
at that stage. This patch works around that issue.
