It is now possible to increase or decrease the maximum number of atoms
the VM can handle. The default value is 1048576 (1024*1024).

* cf/compile_warning_as_error:
Add option -Werror in erlc(1)
compile: add flag warnings_as_errors to treat warnings as errors
compile.erl: remove trailing whitespace
OTP-8382 The -Werror option for erlc and the compiler option
warnings_as_errors will cause warnings to be treated as errors.
(Thanks to Christopher Faulet.)

Like in gcc, this option treats warnings as errors.

* egil/binary-gc:
Add documentation for binary heap size settings.
Add tracing capabilities for binary virtual heap
Add min heap size start options to beam and erl
Improve binary garbage collection
OTP-8370 The default settings for garbage collection of binaries has been
adjusted to be less aggressive than in R13B03. It is now also
possible configure the settings for binary GC. See the
documentation for spawn_opt/2-5, erlang:system_info/1,
erlang:system_flag/2, process_flag/2-3, erlang:trace/3, and the
documenation for erl for the new command line options +hms and
+hmbs.

The erl (and beam) start arguments are extended with
the following options:
* +hms Size, sets the default minimum heap size
for processes.
* +hmbs Size, sets the default minimum binary virtual heap
size for processes.
The previous +h Size argument can still be used for backward
compatibility purposes.

The wx application will only work in the SMP emulator,
so the -wx option for 'dialyzer' must force the -smp
option when starting the emulator.
Make sure that -wx in *any* position on the command
line (not only as the first argument) forces the
SMP emulator.
