As part of sys_core_fold, variables involved in bit syntax
matching would be annotated when it would be safe for a later
pass to do the delayed sub-binary creation optimization.
An implicit assumption regarding the annotation was that the
code must not be further optimized. That assumption was broken
in 05130e48555891, which introduced a fixpoint iteration
(applying the optimizations until there were no more changes).
That means that a variable could be annotated as safe for
reusing the match context in one iteration, but a later iteration
could rewrite the code in a way that would make the optimization
unsafe.
One way to fix this would be to clear all reuse_for_context
annotations before each iteration. But that would be wasteful.
Instead I chose to fix the problem by moving out the annotation
code to a separate pass (sys_core_bsm) that is run later after
all major optimizations of Core Erlang has been done.

On Solaris, giving a too long sfv_len results in an
EINVAL error, but data is still transmitted and len is
correctly. So we translate this to a success with that
amount of data sent. This may hide some other errors
that causes EINVAL, but it is the best we can do for now.

Using enter actions for retransmission timers makes the code easier to
understand. Previously the retransmission timer was incorrectly started in
the connection state. Using enter actions feels like a cleaner approach
than bloating the state with more flags.

The need for more trace patterns requires a somewhat different structure.
It was previoiusly a bit difficult to use in e.g. test suites. Now it is easier.

Correct close semantics for active once connections. This was a timing dependent bug the resulted in the close message not always reaching the ssl user process.

In the test group public_key we need to control both the host key
and the user key. This new test case is aimed at faciliate the
user public key testing.
