to handle "lookup without refc++" correctly
which was introduced in 4dcb2ae7810a507b701a30072b2f514cab7ebbdb.
When decrementing refc to zero (in try_delete or prepare_try_delete)
we must always wait thread progress to make sure no thread has done
lookup without refc++ and is just about to do refc++ and thereby revive
the DistEntry. That is, we wait for a potential other thread to either
do refc++ or drop its pointer to the DistEntry.
And if that other thread does refc++ (in erts_ref_dist_entry)
it must also do the extra refc++ for the scheduled pending delete.

- uri_string module used for parsing URIs.
- Removed url_encode option as only valid URIs shall be handled
by the http client.
- The client rejects URIs that are not compliant with RFC 3986.

Refactor supervisor, and store children in a map instead of a list
OTP-14586
|

RFC 2616 requires an absolute URI in 'Location' header field for
redirects. RFC 7231 obsoleted RFC 2616 and allows URI-references.
Updated httpc_response to support URI-references, based on the
URI resolution algorithm defined by RFC 3986 (5.2.2. Transform
References).

The "root cause" error reason was lost when abort_write failed,
e.g. file was already closed, and Mod:abort_write(..) returned an

When a ref is created before performing a receive that will only
receive message containing that ref, there is a compiler optimization
to avoid scanning messages that can't possible contain the newly
created ref.
Magnus Lång pointed out that the implementation of the optimization
is flawed. Exceptions or recursive calls could cause the receive
operation to scan the receive queue from a position beyond the expected
message (that is, the message containing the ref would never be
matched out). See the receive_opt_exception/1 and receive_opt_recursion/1
test cases in receive_SUITE.
It turns out that we can simplify the implementation of the
optimization while fixing the bug (suggested by Magnus Lång). We
actually don't need the c_p->msg.mark field. It is enough to have
c_p->msg.saved_pos; if it is non-zero, it is a valid position in the
message qeueue. All we need to do is to ensure that we clear
c_p->msg.saved_pos when a receive is exited normally or abnormally.
We can clear c_p->msg.saved_pos in JOIN_MESSAGE(), since it is called
both when leaving a receive because a message matched and because there
was a timeout and the 'after' clause was executed. In addition, we
need to clear c_p->msg.saved_pos when an exception is caught.

Retrying close(2) on anything other than HP-UX is likely to close
something entirely different. POSIX says that the state of the file
descriptor is unspecified, and Linux/BSD guarantee that it's closed
on return.
