Remove test_server as a standalone application

The test_server application has previously been deprecated.

In OTP 19, we will move relevant parts of test_server into the
common_test application. Test suites that include test_server.hrl
must be updated to include ct.hrl instead. Test suites that include
test_server_line.hrl must removed that inclusion. Test suites that
call the test_server module directly will continue to work in OTP 19.

The test suites for Erlang/OTP are built and executed in exactly
the same way as previously.

Here are some more details.

The modules test_server*.erl and erl2html2.erl in lib/test_server/src
have been moved to common_test/src.

The test_server.hrl and test_server_line.hrl include files have
been deleted. The macros in test_server.hrl have been copied into
lib/common_test/include/ct.hrl.

The ts*.erl modules and their associated data files in
lib/test_server/src has been been moved to the new directory
lib/common_test/test_server. The ts* modules are no longer built
to lib/common_test/ebin. They will only built when 'make release_tests'
is executed.

The test suite for test_server has been moved to lib/common_test/test.

The rest of the files have been deleted.

+%%
+%% {make,Ref,{Mod,Func,Args}} Mod:Func is a make function, and it is called

+%% then reiterate.
+%%
+%% {Mod,Case,Args} A test case with predefined argument (usually a normal
+%% test case which just got a fresh configuration (see above)).
+%%
+%% {skip_case,{conf,Ref,Case,Comment}} An init conf case gets skipped
+%% by the user. This will also cause the end conf case to be skipped.
+%% Note that it is not possible to skip an end conf case directly (it
+%% can only be skipped indirectly by a skipped init conf case). The
+%% comment (which gets printed in the log files) describes why the case
+%% was skipped.
+%%

+%% The comment (which gets printed in the log files) describes why the
+%% case was skipped.
+%%
+%% {auto_skip_case,{conf,Ref,Case,Comment},Mode} This is the result of
+%% an end conf case being automatically skipped due to a failing init
+%% conf case. It could also be a nested conf case that gets skipped
+%% because of a failed or skipped top level conf.
+%%
+%% {auto_skip_case,{Case,Comment},Mode} This is a normal test case which
+%% gets automatically skipped because of a failing init conf case or
+%% because of a failing previous test case in a sequence.
+%%
+%% -------------------------------------------------------------------
+%% Description of IO handling during execution of parallel test cases:
+%% -------------------------------------------------------------------
+%%
+%% A conf group can have an associated list of properties. If the
+%% parallel property is specified for a group, it means the test cases
+%% should be spawned and run in parallel rather than called sequentially
+%% (which is always the default mode). Test cases that execute in parallel
+%% also write to their respective minor log files in parallel. Printouts
+%% to common log files, such as the summary html file and the major log
+%% file on text format, still have to be processed sequentially. For this
+%% reason, the Mode argument specifies if a parallel group is currently
+%% being executed.
+%%
+%% The low-level mechanism for buffering IO for the common log files
+%% is handled by the test_server_io module. Buffering is turned on by
+%% test_server_io:start_transaction/0 and off by calling
+%% test_server_io:end_transaction/0. The buffered data for the transaction
+%% can printed by calling test_server_io:print_buffered/1.
+%%
+%% This module is responsible for turning on IO buffering and to later
+%% test_server_io:print_buffered/1 to print the data. To help with this,
+%% two variables in the process dictionary are used:
+%% 'test_server_common_io_handler' and 'test_server_queued_io'. The values
+%% are set to as follwing:
+%%
+%%   Value	Meaning
+%%   -----     -------
+%%   undefined	No parallel test cases running
+%%   {tc,Pid}	Running test cases in a top-level parallel group
+%%   {Ref,Pid}	Running sequential test case inside a parallel group
+%%
+%% FIXME: The Pid is no longer used.
+%%
+%% If a conf group nested under a parallel group in the test
+%% specification should be started, the 'test_server_common_io_handler'
+%% value gets set also on the main process.
+%%
+%% During execution of a parallel group (or of a group nested under a
+%% parallel group), *any* new test case being started gets registered
+%% in a list saved in the dictionary with 'test_server_queued_io' as key.
+%% When the top level parallel group is finished (only then can we be
+%% sure all parallel test cases have finished and "reported in"), the
+%% list of test cases is traversed in order and test_server_io:print_buffered/1
+%% can be called for each test case. See handle_test_case_io_and_status/0
+%% for details.
+%%
+%% To be able to handle nested conf groups with different properties,
+%% the Mode argument specifies a list of {Ref,Properties} tuples.
+%% The head of the Mode list at any given time identifies the group
+%% currently being processed. The tail of the list identifies groups
+%% on higher level.
+%%
+%% -------------------------------------------------------------------
+%% Notes on parallel execution of test cases
+%% -------------------------------------------------------------------
+%%
+%% A group nested under a parallel group will start executing in
+%% parallel with previous (parallel) test cases (no matter what
+%% properties the nested group has). Test cases are however never
+%% executed in parallel with the start or end conf case of the same
+%% group! Because of this, the test_server_ctrl loop waits at
+%% the end conf of a group for all parallel cases to finish
+%% before the end conf case actually executes. This has the effect
+%% that it's only after a nested group has finished that any
+%% remaining parallel cases in the previous group get spawned (*).
+%% Example (all parallel cases):
+%%
+%% group1_init   |---->
+%% group1_case1        | --------->
+%% group1_case2        | --------------------------------->
+%% group2_init         | ---->
+%% group2_case1               | ------>
+%% group2_case2               | ---------->
+%% group2_end                              | --->
+%% group1_case3                               (*)| ---->
+%% group1_case4                               (*)| -->
+%% group1_end                                              | --->

+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%%
+%% A module is included in the cover analysis if
+%% - it belongs to the tested application and is not listed in the
+%%   {exclude,List} part of the App.cover file
+%% - it does not belong to the application, but is listed in the
+%%   {include,List} part of the App.cover file
+%% - it does not belong to the application, but is listed in the
+%%   {cross,[{Tag,List}]} part of the App.cover file
+%%
+%% The modules listed in the 'cross' part of the cover file are
+%% modules that are heavily used by other tests than the one where
+%% they are explicitly tested. They should then be listed as 'cross'
+%% in the cover file for the test where they are used but do not
+%% belong.
+%%
+%% After all tests are completed, the these modules can be analysed
+%% with coverage data from all tests where they are compiled - see
+%% cross_cover_analyse/2. The result is stored in a file called
+%% cross_cover.html in the run.<timestamp> directory of the
+%% test the modules belong to.
+%%
+%% Example:
+%% If the module m1 belongs to system s1 but is heavily used also in
+%% the tests for another system s2, then the cover files for the two
+%% systems could be like this:
+%%
+%% s1.cover:
+%%  {include,[m1]}.
+%%
+%% s2.cover:
+%%  {include,[....]}. % modules belonging to system s2
+%%  {cross,[{s1,[m1]}]}.
+%%
+%% When the tests for both s1 and s2 are completed, run
+%% cross_cover_analyse(Level,[{s1,S1LogDir},{s2,S2LogDir}]), and
+%% the accumulated cover data for m1 will be written to
+%% S1LogDir/[run.<timestamp>/]cross_cover.html
+%%
+%% S1LogDir and S2LogDir are either the run.<timestamp> directories
+%% for the two tests, or the parent directory of these, in which case
+%% the latest run.<timestamp> directory will be chosen.
+%%
+%% Note that the m1 module will also be presented in the normal
+%% coverage log for s1 (due to the include statement in s1.cover), but
+%% that only includes the coverage achieved by the s1 test itself.
+%%
+%% The Tag in the 'cross' statement in the cover file has no other
+%% purpose than mapping the list of modules ([m1] in the example
+%% above) to the correct log directory where it should be included in
+%% the cross_cover.html file (S1LogDir in the example above).
+%% I.e. the value of the Tag has no meaning, it could be foo as well
