Remove traces of release_handler reading from filesystem when it has Masters list

There are a couple of places in release_handler and release_handler_1 that assumed it has a disk to read from, which in the case of an erl_prim_loader Loader other than efile is not necessarily true

Add check_paths/2 to do the equivalent of check_path/1 for when there is a Masters list

Change get_vsn to no longer get sent File paths but instead use the Bin since beam_lib:version being sent a file path causes it to read the local file system

Add get_current_vsn/1 as an equivalent to beam_lib:version(code:which(Mod)), but using erl_prim_loader:get_file instead of reading from local file system

rb:stop did sometimes return {error,running}. This came from supervisor:delete_child and happened when the rb_server has not yet terminated when this function was called. Instead of having a separate gen_server call to rb_server for stopping the process, supervisor:terminate_child is now called. This is a synchronous function - i.e. it waits for the process to actually terminate before it returns.

A file descriptor leak in rb:scan_files is corrected. The index file was never closed after reading.

A mismatch in the behavior of rb:filter, when filter included 'no', is corrected. Such filters will now return *all* non-matching reports, not only the 'proplist' reports.

Start and end date for rb:filter/2 was specified as {{Y-M-D},...} in the help text instead of {{Y,M,D},...}. This has been corrected.

If some, but not all, of the sasl environment variables related to the log_mf_h error handler were missing sasl would successfully start but silently skip starting log_mf_h. This is corrected so sasl startup will now fail if one or two of the three variables are given. If none of the variables are given, sasl will start as before without starting log_mf_h.

Change default behaviour to not check src code when creating release

Add new option src_tests to systools:make_script and systools:make_tar. The old option no_module_tests is now ignored as this is the default behaviour.

Honor start type in .rel files when building relup files

Previously, relup file always included an application:start(Application, permanent) apply instruction for every application that appear in the UpTo/DowFrom release file, whatever their start type in the release file.

The new implementation fixes this bug by honoring the start type according to the rel(5) format. If the start type is none, no apply line is included in the relup. If the start type is load, the relup includes instruction to only load the application. Otherwise, the relup includes an instruction to start the application to the according type.

The fix is implemented by adding a new parameter to the add_application high level appup instruction. This new parameter is documented in appup(5).

In R13B04 sys:get_status was modified to invoke format_status/2 in the callback module if the module exports that function. This resulted in a change to the term returned from calling sys:get_status on the supervisor module, since supervisor is a gen_server and gen_server exports format_status. The sasl release_handler_1 module had a dependency on the pre-R13B04 term returned by sys:get_status when invoked on a supervisor, so the R13B04 change broke that dependency.

This problem has been fixed by change release_handler_1 to handle both the pre-R13B04 and R13B04 terms that sys:get_status can return from a supervisor.

The re:grep/1 function now uses the 're' module instead of the deprecated 'regexp' module. There are new functions rb:filter/1 and rb:filter/2 for easier filtering of reports. (Thanks to Alvaro Videla.)

There is new function sasl_report:format_report/3 that works like the existing sasl_report:write_report/3 function except that it returns a formatted string. Note that there is currently no documentation for the sasl_report module. (Thanks to Jay Nelson.)

Added an option {outdir,Dir} to the functions in systools, making it possible to specify in which directory a boot script, relup file or release package file should be placed.

Also, when using systools:make_tar/2 to create a release package file, the boot script, relup file and sys.config are now searched for also in the current working directory and any directory specified by the path option, not only in the directory of the .rel file.

As part of the work some minor bugs have been corrected:

Added a number of functions to release_handler which makes it possible to test upgrade and downgrade of applications according to an .appup file "on the fly":

A new option {update_paths,Bool} has been added for release_handler:install_release/2. It indicates if all application code paths should be updated (Bool==true), or if only code paths for modified applications should be updated (Bool==false, default).

release_handler:set_unpacked/2 now returns an error tuple if a specified application directory does not exist.
