Merge branch 'v0.10.17-release' into v0.10
Now working on 0.10.18
blog: Post for v0.10.17
tools: script to report [un]stable build
tools: script release steps after jenkins build
uv: update to v0.10.15
stream: Pass 'buffer' encoding to decoded writables

Since the encoding is no longer relevant once it is decoded to a Buffer,
it is confusing and incorrect to pass the encoding as 'utf8' or whatever
in those cases.

Closes #6119
doc: Adjust util stability index to 'API Frozen'

Closes #6087
stream: check _events before _events.error

This fixes the regression introduced by 5458079, which breaks the
net/net-pipe benchmark script.

Closes #6145

timer_wrap: Timer.now always update loop time

In `Timer.now` always update the loop time by calling uv_update_time.
Previously we were trying to cache the loop time to prevent extra
syscalls. While a noble goal, it can cause timers to fire early in
certain circumstances. Especially seen in cpu bound work loads or work
loads with synchronous file operations.
pipe_wrap: squelch integer type conversion warning
vm: update API to use options argument

Passing a filename is still supported in place of certain options
arguments, for backward-compatibility, but timeout and display-errors
are not translated since those were undocumented.

Also managed to eliminate an extra stack trace line by not calling
through the `createScript` export.

Added a few message tests to show how `displayErrors` works.
vm: document vm2's changes.

- The caveats no longer apply.
- Document options arguments, including `displayErrors` and the
  different things it means in each place.
- Re-did examples to be more on point, e.g. `runInContext` example
  runs multiple scripts in the same context.
- Documented how `vm.createContext`s meaning has substantially changed,
  and is now more of a "contextifier" than a "creator."
- Reordered vm functions to be readable in order; the concept of
  contextifying needs to come before `runInContext` and
  `runInNewContext`.
- Documented new `vm.isContext`.
- Documented the `vm.Script` constructor, instead of `createScript`,
  since factory methods are silly and we wanted to document the class's
  methods anyway.
- Documented `script.runInContext`.
- Change stability to stable, if I may be so bold.
