Introduce new "Dbgi" chunk

OTP-14369

Store abstract code in the Dbgi chunk

2017-04-25T11:24:22+00:00

The new Dbgi chunk returns data in the following format:

    {debug_info_v1, Backend, Data}

This allows compilers to store the debug info in different
formats. In order to retrieve a particular format, for
instance, Erlang Abstract Format, one may invoke:

    Backend:debug_info(erlang_v1, Module, Data, Opts)

Besides introducing the chunk above, this commit also:

  * Changes beam_lib:chunk(Beam, [:abstract_code]) to
    read from the new Dbgi chunk while keeping backwards
    compatibility with old .beams

  * Adds the {debug_info, {Backend, Data}} option to
    compile:file/2 and friends that are stored in the
    Dbgi chunk. This allows the debug info encryption
    mechanism to work across compilers

  * Improves dialyzer to work directly on Core Erlang,
    allowing languages that do not have the Erlang
    Abstract Format to be dialyzer as long as they emit
    the new chunk and their backend implementation is
    available

Backwards compatibility is kept across the board except
for those calling beam_lib:chunk(Beam, ["Abst"]), as the
old chunk is no longer available. Note however the "Abst"
chunk has always been optional.

Future OTP versions may remove parsing the "Abst" chunk
altogether from beam_lib once Erlang 19 and earlier is no
longer supported.

The current Dialyzer implementation still supports earlier
.beam files and such may also be removed in future versions.

Add unicode_util

2017-04-24T10:16:50+00:00

A base for unicode functions, not intended to be a user api.

Whitespace returns a reasonable subset of non nobreak whitespace
characters.

Implementation notes:

Make function clauses instead of using arrays and store tuples instead
of maps to save space.

Update erl_tar to support PAX format, etc.

2017-02-16T13:55:15+00:00

This commit introduces the following key changes:

- Support for reading tar archives in formats currently in common use,
  such as v7, STAR, USTAR, PAX, and GNU tar's extensions to the
  STAR/USTAR format.
- Support for writing PAX archives, only when necessary, using USTAR
  when possible for greater portability.

These changes result in lifting of some prior restrictions:

- Support for reading archives produced by modern tar implementations
  when other restrictions described below are present.
- Support for filenames which exceed 100 bytes in length, or paths which
  exceed 255 bytes (see USTAR format specification for more details on
  this restriction).
- Support for filenames of arbitrary length
- Support for unicode metadata (the previous behaviour of erl_tar was
  actually violating the spec, by writing unicode-encoded data to fields
  which are defined to be 7-bit ASCII, even though this technically
  worked when using erl_tar at source and destination, it may not have
  worked with other tar utilities, and this implementation now conforms
  to the spec).
- Support for uid/gid values which cannot be converted to octal
  integers.
