Summary: Fixes T3046. Git has no minimum or bad versions; svn has no minimum and the bad version of 1.7.1, and mercurial has a minimum of 1.9 and bad versions 2.2 and 2.1. These error messages are specific about the problem but do not include the details as to what specifically is bad about a given version. I don't think that's really necessary - the details don't help solve the problem and its probably booooooring at best to the average user. The details about a bad version are included in the code however.
Test Plan: hardcoded a VCS array to let me test all the VCS stuff. added some phlog() calls to make sure the VCS version parsing stuff was working correctly relative to the version(s) on my system. played around with setting minimum versions and bad versions and saw good results depending on what I set.

https://github.com/facebook/phabricator/issues/389#issuecomment-36612511
The problem is similar to the original report, but not identical. In this case, we're following a sequence of steps like:
- Run setup checks.
- Check for enabled providers, in order to raise "no providers configured yet" warning.
- Try to generate login/redirect URIs.
- Build the request.
- Set the default base URI.
- Run normal code.
Since we try to generate URIs before we provide a default, this fatals. Instead, don't try to build objects.
An alternative fix might be to try to set defaults earlier, but we depend on some config and on building the Request in order to be able to figure out if a request is HTTP or HTTPS right now. We could assume one, or guess, or use protocol-relative URIs (`///host.com`), but I think this fix is a little cleaner overall. If we keep hitting similar stuff, we could look into alternate fixes.
We could also set some kind of "setup mode" flag and make `getURI()` if it's called during setup mode to detect these during testing. I'd like to hit one more of these before doing that, though.
Test Plan: Reproduced the issue, applied the patch, verified this fixes it.

Summary:
Ref T4420. Tokenizers currently operate in "preload" or "ondemand" modes. In the former mode, which is default, they'll try to load the entire result list when a page loads.
The theory here was that this would slightly improve the experience for small installs, and once they got big enough they could switch to "ondemand". In practice, several issues have arisen:
- We generally don't have a good mechanism for telling installs that they should tweak perf config -- `metamta.send-immediately` is the canonical example here. Some large installs are probably affected negatively by not knowing to change this setting, and having settings like this is generally annoying.
- We have way way too much config now.
- With the advent of ApplicationSearch, pages like Maniphest make many redundant loads to prefill sources like projects. Most of the time, this data is not used. It's far simpler to switch everything to ondemand than try to deal with this, and dealing with this would mean creating two very complex divergent pathways in the codebase for a mostly theoretical performance benefit which only impacts tiny installs.
- We've been using `tokenizer.ondemand` forever on `secure.phabricator.com` since we have many thousands of user accounts, and it doesn't seem sluggish and works properly.
Removing this config is an easy fix which makes the codebase simpler.
I've retained the ability to use preloaded sources, since they may make sense in some cases (in at least one case -- task priorities -- adding a static source pathway might make sense), and they're part of Javelin itself. However, the code will no longer ever go down that pathway.
Test Plan: Used `secure.phabricator.com` for years with this setting enabled.

Summary:
Currently, we try to mostly-kind-of-work if daemons aren't running (for example, we send mail in-process). I want to stop doing this. A major motivator is that `metamta.send-immediately` is confusing for a lot of users and frequently the cause of performance problems. Increasingly, functionality of applications depends on the daemons (Harbormaster, Drydock, Nuance all require daemons to do anything at all). They're also fairly stable/robust/well-tested and no reasonable install should be running without them.
This will let us simplify or remove some flags (like `metamta.send-immediately`) and simplify some other processes like search indexing.

Moving forward, every PHID type will be provided by a `PhabricatorPHIDType` subclass, which will manage loading it, etc.
