SSH: add support for aes128-ctr and hmac-sha2-256

This cipher and hmac are RECOMMENDED as per RFC4344 and
RFC6668. RFC4344 notes that aes128-ctr is likely to be
promoted to REQUIRED in the near future.

Some distros of Linux and Illumos are already shipping with
aes128-cbc and 3des-cbc disabled by default due to security
concerns around chosen-plaintext attacks and other information
leaks. Without this patch, OTP SSH cannot connect to these
SSH servers in their default configuration.
Properly track column numbers in erl_scan

This is a partial revert of 05c4d31b2c5c5f6ade7d91b55c598fe7fa58e509 in
which a new macro `?STR()` was introduced. This macro shouldn't be used in
scan_number/6 and scan_based_int/6 because the length of the string is
needed when computing column numbers through tok3/8.

fix escript archive symlinked across drives

real_path method used while prim loading archive files was not taking into account
the fact that windows directory symlinks can be across different drives
(eg. c:\tmp\test is a symlink to j:\tmp\test). when performing a path split the drive
precedes the symlink, but that has be rewritten also since it's different. This issue
never arises in Unix since obviously there are no drives

[ct] Update runtime dependencies towards test_server

Ticket OTP-11971 introduced a runtime dependency towards
test_server-3.7.1, since the interface between test_server and
common_test was changed. Erroneously, the common_test.app file was not
updated according to this. This has now been corrected.
Fix filelib:wildcard/2 when 'Cwd' ends with a dot

In such case, filelib:wildcard/2 returned truncated results:

  1> file:set_cwd("/usr/lib/erlang/lib").
  ok
  2> filelib:wildcard("stdlib-*/ebin/*.app", filename:absname(".")).
  ["dlib-2.1/ebin/stdlib.app"]
odbc: Suppress signedness warnings for 'char *'

Three different pointer types are used for strings.

SQLCHAR pointer - used against ODBC driver
char pointer - used against erl_interface
byte pointer - used internally

SQLCHAR is 'unsigned char' while erl_interface is 'signed char'

byte pointer should probably not be used at all.
Use compile options when dialyzing beam files

Fetch the compile options from beam files, and use them when creating
core from the abstract code. Previously the options were ignored.
