The actual port id is used to create a key from the
pointer value which is the ErlDrvPort. To do this
a new driver api function driver_async_port_key is
added and the driver API minor version is updated.
The documentation is updated and the faulty description of
how to spread ports over async threads is updated to
use the new API.
Testcase also added.

The bug manifests so that initialization of an automatic variable
happens after a pointer to the variable is dereferenced, causing
build_exec_return to take the wrong branch by default.
The bug is verified to happen even outside the VM and
is reported to FreeBSD as trouble ID gnu/181328.
The workaround is a slight code rewrite which is optimized differently.
Also removed two warnings about dereferencing type-punned
pointers, which did not affect the bug.

This is needed as some gcc versions seems to optimize this undefined
behaviour in a way which breaks this code.

Just some clarifying comments to future progremmers to keep the relation
between error returns from the two functions.

Added to re:run and sets the corresponding fields in 'extra' struct
for the PCRE match engine. The result can be viewed by also
setting 'report_errors' when matching.
Some housekeeping was also done...
The offset option also did not properly check for offset's >= 0.
Change nomatch to BADARG when pre-compiled mp() is faked:
By constructing a 5-tuple with faked content but the right data types,
you could do a re:run which returned nomatch when in fact the mp() was
bad. The cheapest solution is to check the return from pcre_exec
better.
Remove unreachable code in erts_bif_re.c:
Replaced tests for things that logically simply
cannot happen with ASSERT.

Add notempty_atstart, no_start_optimize, ucp and
never_utf options from new PCRE version.
Use the new notempty_atstart in global matching.
Add inspect/2 function
Correctly handle dupnames when capturing a name, as
in Perl, get the leftmost matching occurence.
Also added all_names, to get all the names in the pattern
in alphabetical (name) order.
To be able to use this in global matching, an inspect
function that can dig out a namelist was added.

Since: R16B01
Symptom: A spawned process may get the same PID as an existing
process. The new process will "steal" the PID and make the old process
unreachable through the PID.
The problem also applies to port identities but has only been seen
for processes.
Conditions: SMP emulator with at least two scheduler threads. Rapid
spawning and termination of a large number of processes. A small
number of free slots in the process table will also increase the risk
for this bug.
Workaround: Use command line options "+P legacy" and "+Q legacy"
Cause: The race happens if a process terminates and gets stalled while
releasing its process table slot. The stall has to be so long (due to OS
preemptive scheduling most probably) for other schedluer threads to
consume all other free slots for newly spawn processes.
Fix: Write invalid-markers in the free-pid-table and do atomic exhange
operations in retry-loops to make sure each thread gets a unique PID.

- Remove trailing whitespaces
- Spelling fixes
- Replace "deferred" with "deprecated" where applicable
- Remove reference to non-existing "async_ready" entry point
