erts_debug:instructions/0 is useful for finding which specific

The options for the ets:new/2 call has changed recently. There are
read_concurrency hints as well as compressed tables. The hipe/dialyzer
did not take this into account. This patch corrects the problem by
going through the documentation and altering the type specification.
The error fixed is with the dialyzer. When constructing an ETS table
with, e.g., {read_concurrency, true}, the dialyzer will report that the
caller of ets:new/2 will not return.
; First, we update the documentation from the ets man page.
; Second, we reorder the type specification of keypos so they appear
in the same order as in the documentation.
; Finally, we add the missing read_concurrency and compressed Tweak
options.

The introduction of filenames being unicode binaries revealed a problem
in the type analysis of the native code compiler which resulted in an
infinite loop when compiling the 'filename' module.
In addition, the hard-coded type information for the built-in functions
of the 're' module was out-of-date, which resulted in erroneous type
information for 'filelib' functions being stored in the PLT.

* lukas/hipe/decode_packet_type:
Update httppacket type to return both strings and binaries
|

Also corrected type-info for bifs
|

Dialyzer for a long time now has had hard-coded type information about
key functions of the 'file' and 'code' modules in 'erl_bif_types'.
Some of this information was not up-to-date according to the published
Erlang/OTP documentation, while some other part contained small errors.
Now that specs are available, this information should be moved to the
corresponding files, not be hard-coded in erl_bif_types.
This change takes out all information for the 'file' module and fixes
some small errors in type information for the 'code' module.

Although the {encoding, encoding()} set of options is documented in
the manual page of the 'file' module, they do not appear in the Mode
description on that page nor in the mode() type declaration.
The patch adds this information in both the code of the module and
the documentation of the module.
To avoid duplication, the declaration of the encoding() type is added
to the 'unicode' module where it most probably belongs.
While at it, added a proper declaration for posix(), took out the
now superfluous information about the types of file:open/2 from the
erl_bif_types module, and corrected the return type of file:open/2
so that it corresponds to the published documentation.

elib_malloc is an alternate memory allocator that
is no longer possible to build.

The code handling this BIF did not take into account that
the fun in the first argument that could return []
and therefore the return value of the BIF could also be [].

erlang:garbage_collect_message_area/0 is undocumented and unsupported.

(erlang:port_call/2 is undocumented.)

These are aliases for '++'/2 and '--'/2.

While at it, introduce a new type for adler32 and crc32
and use it consistently within the file.

A stub function that is supposed to be replaced by a NIF usually
calls erlang:error/1 to cause an exception if the NIF library
is not loaded. For example:
foo() ->
erlang:error(nif_not_loaded).
The problem is that although erlang:error/1 will normally never be
called, Dialyzer will think that any call to the function will fail
and thus generate false warnings. Adding a spec for the function
will not help because Dialyzer will not believe the spec.
Add erlang:nif_error/1,2 that work exactly like erlang:error/1,2.
Define the return types for both BIFs to be t_any().
erlang:nif_error is used like this:
-spec foo() -> binary().
foo() ->
erlang:nif_error(nif_not_loaded).
(The -spec is optional but highly recommended, since Dialyzer
otherwise has no chance to figure out the types.)

erts_debug:lock_counters/1 is an undocumented BIF used by
the 'lcnt' module in the 'tools' application.

BIFs and extends the return value of erlang:load_module/2.
