Improve error messages for PHABRICATOR_ENV
Summary:
- Allow user to specify "myconf" (recommended) or "myconf.conf.php" (less
surprising).
- Make sure syntax errors and other problems are surfaced.
- If the configuration value isn't valid, give them a list of all valid
values.
Test Plan:
- Added a syntax error, got a useful error.
- Set PHABRICATOR_ENV to a silly value, got a list of valid values.
- Set PHABRICATOR_ENV to have .conf.php suffix, site still worked.

Create AphrontWriteGuard, a backup mechanism for CSRF validation
Summary:
Provide a catchall mechanism to find unprotected writes.
- Depends on D758.
- Similar to WriteOnHTTPGet stuff from Facebook's stack.
- Since we have a small number of storage mechanisms and highly structured
read/write pathways, we can explicitly answer the question "is this page
performing a write?".
- Never allow writes without CSRF checks.
- This will probably break some things. That's fine: they're CSRF
vulnerabilities or weird edge cases that we can fix. But don't push to Facebook
for a few days unless you're prepared to deal with this.
- **>>> MEGADERP: All Conduit write APIs are currently vulnerable to CSRF!
<<<**
Test Plan:
- Ran some scripts that perform writes (scripts/search indexers), no issues.
- Performed normal CSRF submits.
- Added writes to an un-CSRF'd page, got an exception.
- Executed conduit methods.
- Did login/logout (this works because the logged-out user validates the
logged-out csrf "token").
- Did OAuth login.
- Did OAuth registration.
