Ensure that we cannot get any dangling pointers into code that
has been purged. This is done by a two phase purge. At first
phase all fun entries pointing into the code to purge are marked
for purge. All processes trying to call these funs will be suspended
and by this we avoid getting new direct references into the code.
When all processes has been checked, these processes are resumed.
The new purge strategy now also completely ignore the existence of
indirect references to the code (funs). If such exist, they will
cause bad fun exceptions to the caller, but will not prevent a
soft purge or cause a kill of a process having such live references
during a hard purge. This since it is impossible to give any
guarantees that no processes in the system have such indirect
references. Even when the system is completely clean from such
references, new ones can appear via distribution and/or disk.

Update INSTALL.md

* Fixed a grammatical error.

Remove the options:
--enable-darwin-universal
--enable-darwin-64bit
The --enable-darwin-universal option turns on universal binaries
(Intel/PPC). It does not work on modern releases of OS X, and
OTP 19 will most not likely build on an OS X release that still
supports universal builds.
The --enable-darwin-64bit option is not needed, because 64-bit builds
are default on modern OS X releases. There is also the generic
--enable-m64-build option.

I found that I needed to take the two steps I added to INSTALL.md for
this PR, or else fop execution when doing a "make docs" would fail with
either a Java ClassNotFoundException or command "fop" not found:
* Adding the FOP install directory to $FOP_HOME
* Adding the fop script to $PATH

- Documented the configure switch --with-clock-resolution=<RES>
- Changed default clock source for OS system time on Darwin to
gettimeofday(). In order to use clock_get_time(CALENDER_CLOCK, ...)
on Darwin, the user has to pass --with-clock-resolution=high when
configuring the build.

wxWidgets does not have a branch named `WX_3_0_branch`, but has
`WX_3_0_BRANCH` Trying to clone with `--branch` set to the lowercase
name fails. Fix branch name to `WX_3_0_BRANCH`.

Remove OSE from erl_interface
ose: Remove all code related to the OSE port

The OSE port is no longer supported and this commit removed it
and any changes related to it. The things that were general
improvements have been left in the code.

Since no bug fixes are done anymore on the 2.8 branch it is time

* Use of __atomic builtins when available.
* Improved configure test that checks for missing memory
barrier in __sync_synchronize(). The old approach was to
verify known working gcc versions and check gcc version at
compile time. Besides not being very safe, the old approach
often unnecessarily caused usage of the very expensive
workaround.
* Introduced (no overhead) workaround for missing clobber in
__sync_synchronize() when using buggy LLVM implementation of
__sync_synchronize().
* Implement native memory barriers for ARM processors supporting
the DMB instruction.
* Use of volatile store on Alpha as atomic set operation if no
__atomic_store_n() is available (already used on x86/x86_64
Sparc V9, PowerPC, and MIPS). Fallback used when not using
volatile store is typically very expensive.
* Use volatile load on Alpha and ARM as atomic read operation
if no __atomic_load_n() is available (already used on
x86/x86_64 Sparc V9, PowerPC, and MIPS). Fallback when not
using volatile load is typically very expensive.

The master branch has incompatible changes by default. The safest
course for now is to use the WX_3_0_branch.

In 9f57d8c4f86323cf7481c9a7e512486087bb5542, the configure option
--enable-shared-zlib. It was replaced with --enable-builtin-zlib.

The build and install documentation was not complete
and needed some restructuring.
