epriestley 2b7210260f Allow Phabricator storage engines to be extended and configured
Summary:
See T344. Currently, there's a hard-coded 12MB filesize limit and some awkward
interactions with MySQL's max_allowed_packet. Make this system generally more
robust:

  - Move the upload limit to configuration.
  - Add setup steps which reconcile max_allowed_packet vs MySQL file storage
limits.
  - Add a layer of indirection between uploading files and storage engines.
  - Allow the definition of new storage engines.
  - Define a local disk storage engine.
  - Add a "storage engine selector" class which manages choosing which storage
engines to put files in.
  - Document storage engines.
  - Document file storage classes.

Test Plan:
Setup mode:

  - Disabled MySQL storage engine, misconfigured it, configured it correctly.
  - Disabled file storage engine, set it to something invalid, set it to
something valid.
  - Verified max_allowed_packet is read correctly.

Application mode:

  - Configured local file storage.
  - Uploaded large and small files.
  - Verified larger files were written to local storage.
  - Verified smaller files were written to MySQL blob storage.

Documentation:

  - Read documentation.

// generally better if Phabricator uses the user's real address as the "From"
// since the messages are easier to organize when they appear in mail clients,
// but this will only work if the server is authorized to send email on behalf
// of the "From" domain. Practically, this means:
// - If you are doing an install for Example Corp and all the users will
// have corporate @corp.example.com addresses and any hosts Phabricator
// is running on are authorized to send email from corp.example.com,
// you can enable this to make the user experience a little better.
// - If you are doing an install for an open source project and your
// users will be registering via Facebook and using personal email
// addresses, you MUST NOT enable this or virtually all of your outgoing
// email will vanish into SFP blackholes.
// - If your install is anything else, you're much safer leaving this
// off since the risk in turning it on is that your outgoing mail will
// mostly never arrive.

// you can use a single, non-unique reply to address and authenticate users
// based on the "From" address by setting this to 'true'. This trades away
