We have decided that we don't want to deal with the compilations
of prim_file:get_cwd() returning a binary when the current
directory name cannot be translated losslessly to a list (i.e.
when the run-time system was started with +fnu and the current directory
name contains bytes that are not part of a valid UTF-8 sequence).
Therefore, if prim_file:set_cwd() is given a binary as the pathname,
we will need to check the binary to make sure it can be translated
to a list. We will introduce a new BIF, called prim_file:is_translatable/1,
which will check both filename encoding mode, and if it is one of
Unicode modes, the binary as well.
We don't need to do anything special if prim_file:set_cwd() is passed
a list.

The fix affects list_dir and read_link. Raw filenames are now
never produced, just consumed even if +fnu or +fna is used on
Linux etc.
This also adds the options to get error return or error handler
warning messages with +fn{u|a}{i|w|e} as an option to erl.
This is still not documented and there needs to be other versions
of read_dir and read_link to facilitate reading of all types
of filenames and links.
A check that we will not change to an invalid directory is also needed.

Currently, the format of the return value from drv_command/3 is
determined solely by the efile driver's response. In a future
commit, we will need to produce different return values that
also dependend on which function in prim_file that was called;
thus, we will need some way to pass down some sort of state
to drv_get_response/2.
As a preparation for that, allow the third argument of drv_command/3
to be a fun. That also allows us to remove the convoluted special
case handling of the list_dir operation.

Ports for operations that did not directly operate on a file (such
as listing the files in a directory) was always opened in a binary
mode, but there was still code that supported such port opened in
non-binary mode.
Since we are about to update the code reading directories, and we
don't want to bother we supporting non-binary ports, make sure that
we force the use of binary mode.

The assert_fls/2 and assert_type/3 functions both return the
Vst passed to them, but all callers ignore the return value.
Given the name of the functions, they are not expected to return
anything. Make it so by changing the return value to 'ok'.
There are two calls to bsm_get_context/2 used only to validate
that the match context is valid. Call bsm_validate_context/2
instead.
In bsm_validate_context/2, explicitly match the return value of
bsm_get_context/2 to '_' to make it clear that it is not used.

The unicode update of test_server for R16A introduced a few potential
errors when logging to files. Sometimes ~tp or ~ts was used for
formatting also when writing to files that were not opened with the
{encoding,utf8} option. If then the argument contained unicode
characters above 255, the file descriptor would crash. This has been
corrected by the following modifications:
* Since the 'unexpected_io' log file is used only when the test case
HTML file is not available (e.g. between test cases), this file is
now also a HTML file and as other test_server HTML logs it is always
UTF-8 encoded
* Since it is possible to change which information is going to which
log file (with test_server_ctrl:set_levels/3), we do not have full
control over which information is written to which file. This means
that any printout could be written to the 'major' log file
(suite.log), which was earlier encoded as latin1. To avoid crashing
this file descriptor due to unicode strings, the 'major' log file is
now also encoded in UTF-8 (possible incopatibility).
* The cross_cover.info file is no longer a text file which can be read
with file:consult/1, instead it is written as a pure binary file
using term_to_binary when writing and binary_to_term when reading.
* The encoding of the file named 'last_name', which only content is
the path to the last run.<timestamp> directory, is now dependent on
the file name mode of the VM. If file names are expected to be
unicode, then the 'last_name' file is UTF-8 encoded, else it is
latin1 encoded.
Also, ~tp is changed back to ~p unless it is somehow likely that the
argument includes strings. It is not obvious that this is the correct
thing to do, but some decission had to be taken...

The ber_bin_v2 backend calls a NIF function to decode all tags
and lengths. Even open types that should not be decoded will also be
decoded, which makes it necessary to later re-encode the data using
a NIF function.
The NIF function incorrectly encoded lengths.

The test_modified_x420/1 test case had several problems that
prevented it to detect the bugs it was supposed to find:
1) There was a 'catch' at the top-level so that it could never fail.
2) There was a call to the now non-existing ssl_base64 module.
3) It did not test all options for the BER backend.
While at it, also clean way the remaining ?line macros and some
out-commented code.

It does not make sense to return multiple values from a sequence
argument and the Kernel Erlang passes can't cope with it.
The linting pass now knows how to detect this kind of defunct code and
the Core code folding pass is changed to not generate code like that
when optimizing away multiple-valued lets in effect mode.
