Fix typo in common_test documentation for the -join_specs flag
Remove a superfluous echo in the emulator Makefile

It pollutes the output of silent rules.
wx: Fix configure for win64 with wxWidgets-3.0
wx: Fix listCtrl sort callback
wx: Fix possibility to fetch early open msgs on mac

Mac doesn't add clicked files to program arguments, a callback
is invoked instead, send msgs to erlang about them.
wx: Fix memory garbage collector
wx: Added misc functions

Nice to have functionality
wx: Add wxLocale class
wx: Send destroy message direct

Messages was routed via the wxe_server process, which caused process
to never get the message.
Change the subtag used for maps from 0xB to 0xF

The subtag chosen for maps breaks crucial assumptions in other parts of
the system, in particular the native code generation scheme used in the
HiPE compiler. Therefore it is better to use 'the other' unused subtag.

The main change here is the use of 0xF subtag for maps instead of 0xB.
The rest of the differences are changes to and additions of comments.

One more comment from my part.
I noticed that the file contains the following two lines:

The comment of the second line is most certainly a copy and paste error
and should be appropriately fixed by the OTP developers. More importantly,
it would be great if that subtag (0x7) turned out to be unused and could
be used for maps instead of the 0xF one. This might turn out very handy
in the future. I can elaborate on this, if needed.

Relax time limits for parallel groups tests
erts: Adjust is_external_header() for new map tag

stdlib: Fix map type listing
wx: loosen testcase

Stabilize tests for all kind of machines

Old sparc (and newer smaller) machines timeouts in 'random_ref_comp'
decrease load and increase timeouts.

Supervisor:
Turn up accepted time, since if non-linear it should be much worse,
now the test failes on slow multicore machines

Remove memory tests, they fail sometimes and those tests are not
needed to be tested. Hard to predict GC's and other processes behaviours.
