epriestley d16454d45d Improve a race condition in session establishment code
Summary:
If you try to establish several sessions quickly (e.g., by running several
copies of "arc" at once, as in "arc x | arc y"), the current logic has a high
chance of making them all pick the same conduit session to refresh (since it's
the oldest one when each process selects the current sessions). This means they
all issue updates against "conduit-3" (or whatever) and one ends up with a bogus
session.

Instead, do an update against the table with the session key we read, so only
one process wins the race. If we don't win the race, try again until we do or
have tried every session slot.

Test Plan:
  - Wiped conduit sessions, ran arc commands to verify the fresh session case.
  - Ran a bunch of arc piped to itself, e.g. "arc list | arc list | arc list |
...". It succeeds up to the session limit, and above that gets failures as
expected.
  - Manually checked the session table to make sure things seemed reasonable
there.
  - Generally ran a bunch of arc commands.
  - Logged out and logged in on the web interface.

Phabricator is a open source collection of web applications which make it easier
to write, review, and share source code. Phabricator was developed at Facebook.

This is an early release. It's pretty high-quality and usable, but under
active development so things may change quickly.
