Fixes T11537. See that task for discussion.
Although we could accommodate these faithfully, it requires a huge migration and affects one repository on one install which was written with buggy tools.
At least for now, just replace out-of-32-bit-range epoch values with the current time, which is often somewhat close to the real value.
Test Plan:
- Following the instructions in T11537, created commits in 40,000 AD.
- Tried to import them, reproducing the "epoch" database issue.
- Applied the patch.
- Successfully imported future-commits, with some liberties around commit dates. Note that author date (not stored in an `epoch` column) is still shown faithfully:

Fixes T9235. When the stars align, PHP 5.6 or newer emits a deprecation warning on startup about "always_populate_raw_post_data" which occurs too early for us to intercept and can break responses by adding garbage to the output.
These settings appear to be sufficient:
```
always_populate_raw_post_data = 1
display_errors = 1
display_startup_errors = 1
error_reporting = -1
```
Then make a request with an unusual content type:
```
$ curl -X POST -H "Content-Type: application/json" -d "{foo: bar}" http://phabricator.example.com/
```
This triggers the warning:
```
<br />
<b>Deprecated</b>: Automatically populating $HTTP_RAW_POST_DATA is deprecated and will be removed in a future version. To avoid this warning set 'always_populate_raw_post_data' to '-1' in php.ini and use the php://input stream instead. in <b>Unknown</b> on line <b>0</b><br />
<br />
...
```
To avoid this, just instruct administrators to set this value to "-1", which completely disables the feature and silences the warning.

- Reproduced this issue by following the instructions above.

Test Plan: Create objects (tasks, slowvotes, etc.) then mention the object names in chat (with the bot running). The bot should respond with helpful links to the given objects. Then add the object names to the blacklist through the config web UI. This apparently triggers the bot to restart itself. Then mention the object names in chat again. The bot should no longer respond with links because those object names have been added to the blacklist regex.

Summary:
Ref T11522. This tries to reduce the cost of rewriting a repository by making handles smarter about rewritten commits.
When a handle references an unreachable commit, try to load a rewrite hint for the commit. If we find one, change the handle name to "OldHash > NewHash" to provide a strong hint that the commit was rewritten and that copy/pasting the old hash (say, to the CLI) won't work.
I think this notation isn't totally self-evident, but users can click it to see the big error message on the page, and it's at least obvious that something weird is going on, which I think is the important part.
Some possible future work:
- Not sure this ("Recycling Symbol") is the best symbol? Seems sort of reasonable but mabye there's a better one.

Ref T6996. Depends on D16407. This does the same stuff as D16407, but for `bin/storage renamespace`. In particular:
- Support writing directly to a file (so we can get good errors on failure).
- Support in-process compression.
Also add support for reading out of a `storage dump` subprocess, so we don't have to do a dump-to-disk + renamespace + compress dance and can just stream out of MySQL directly to a compressed file on disk.
This is used in the second stage of instance exports (see T7148).
It would be nice to share more code with `bin/storage dump`, and possibly to just make this a flag for it, although we still do need to do the file-based version when importing (vs exporting). I figured that was better left for another time.
Test Plan:
Ran `bin/storage renamespace --live --output x --from A --to B --compress --overwrite` and similar commands.
Verified that a compressed, renamespaced dump came out of the other end.

Summary:
Ref T6996. If you do this kind of thing in the shell, you don't get a good error by default if the `dump` command fails:
```
$ bin/storage dump | gzip > output.sql.gz
```
This can be worked around with some elaborate bash tricks, but they're really clunky and uninintuitive.
We also need to do this in several places (while writing backups; while performing exports), and I don't want to copy clunky bash tricks all over the codebase.
Instead, provide `--output` and `--compress` flags which just do this processing inside `bin/storage dump`. It will fail appropriately if any of the underlying operations fail. This also makes the write a little safer (refuses to overwrite) and the code more reusable.
Test Plan:
- Did three dumps, with no flags, `--output`, and `--output --compress`.
- Verified all three took similar amounts of time and were identical except for "Date Exported" timestamps in comments (except that the compressed one was compressed).
- Used `gunzip` to examine the compressed one, verified it was really compressed.
- Faked a write error, saw properly command behavior (clean up file + exit with error).

- The "no phcid" errors happen when bots try to go through the login flow.
All of these are clearly communicated to human users, commonly encountered by bots, and not useful to log.
I collapsed the `CSRFException` type into a standard malformed request exception, since nothing catches it and I can't really come up with a reason why anything would ever care.

Summary:
Ref T11473. If you write a method like `get_stuff(ids)` and then call it with an empty list of IDs, you can end up passing an empty constraint to Conduit.
If you run a `*.search` method with such a constraint, like this one:
```
{
"ids": []
}
```
...we have three possible beahviors:
# Treat it like the user passed no constraint (basically, ignore the constraint).
# Respect the constraint (return no results).
# Error.
Currently, we do (1). However, this is pretty confusing and I think clearly the worst option, since it means `get_stuff(array())` in client code will often tend to return a ton of results.
We could do (2) instead, but this is also sort of confusing (it may not be obvious why nothing matched, even though it's an application bug) and I think most reasonable client code should be doing an `if ($ids)` test: this test makes clients a little more complicated, but they can save a network call, and I think they often need to do this test anyway (for example, to show the user a different message).
This implements (3), and just considers these to be errors: this is the least tricky behavior, it's consistent with what we do in PHP, makes fairly good sense, and the only cost for this is that client code may need to be slightly more complex, but this slightly more complex code is usually better code.
Test Plan: Ran Conduit `*.search` queries with `"ids":[]` and `"phids":[]`, got sensible errors instead of runaway result sets.
