# Description of Changes
This exports the following API from `spacetime:sys@1.0`:
```ts
export type ModuleHooks = {
__describe_module__(): Uint8Array;
__call_reducer__(
reducerId: u32,
sender: u256,
connId: u128,
timestamp: bigint,
argsBuf: Uint8Array
): { tag: 'ok' } | { tag: 'err'; value: string };
};
export function register_hooks(hooks: ModuleHooks);
```
This is then called by the `spacetimedb` package. This means that users
no longer need to export `__call_reducer__` and `__describe_module__`
from their own code, and differently from how it was before it doesn't
pollute the global namespace. It also means that the signatures for
`__call_reducer__` can be changed when we change the ABI version - the
bindings would then do `import { register_hooks } from
"spacetime:sys@2.0";` and that version of the function would expect a
different signature..

2 - it's a change, but not all that different from the existing way
we've been doing it.

Move the global.json file to the repo root, which should make `dotnet`
resolve the correct SDK regardless of the directory it is run in.
Where a copy of the global.json file is needed, symlink it to the one at
the root.
Should fix "C#/Unity - Test Suite".
# Description of Changes
Extends log records with a new field, `function`, which stores the name
of the reducer being executed when the log was produced. I have chosen
to name this field `function` rather than `reducer` because we will soon
be adding procedures, which are not reducers but will also be valid
values for this field.
While making this change, I noticed inconsistent values for injected
logs. Previously, we injected logs in three places, with different
values for the record fields:
1. `SystemLogger` (used when publishing and updating) set `filename:
Some("spacetimedb")` and `target: None`.
2. `log_reducer_error` (used for reducer error returns) set `filename:
None` and `target: Some(reducer)`, with `reducer` being the name of the
reducer.
3. `ModuleHost::inject_logs` (used for calls to nonexistent reducers and
calls with ill-typed arguments) set `filename: Some("external")` and
`target: None`.
With this change, I have decided that injected logs universally have
`filename: Some("__spacetimedb__")` and `target:
Some("__spacetimedb__")`. I have chosen the double-underscore convention
for reserved names to avoid confusion should a user name a source file
or reducer `spacetimedb`. I am not terribly attached to using
`spacetimedb` here, and would be happy to change to some other string,
like `internal` or `system`.
I have further decided that `log_reducer_error` and `inject_logs` both
have access to a sensible non-`None` value for `function` and so should
set it to the name of the reducer. The `target` field is not used for
this. Note that in cases where a client attempts to call a non-existent
reducer, the `function` field of the log record will be set to that
client-supplied non-existent reducer name.
# API and ABI breaking changes
Changes our log record format. This is at least backwards-compatible (as
in, newer consumers can read older logs) because the new field is
optional. I am unsure if it is forwards-compatible (as in, older
consumers reading newer logs) because I don't know if `serde_json` will
ignore unknown fields or will error.

# Testing
- [x] Manually ran `quickstart-chat` (modified to log messages and name
changes) and saw sensible output.
# Description of Changes
PR introduces support for column-level default values via a new
`#[default(...)]` attribute.
It also validates, `default` macro is not used along with `primary_key`,
`unique` or `auto_inc`.

# Description of Changes
Uncommented out code from test, in order to have "delete row by index"
test of C# module code ran.
This is the implementation of a fix for issue

# Description of Changes
Apparently, I missed several license files in #3002. I'm not sure what
method I was using to find them, but apparently it was insufficient.
**This replaces all empty `LICENSE` files with an explicit (symlink to)
BSL license, and all apache licenses with symlinks to the root apache
license.** This PR does not intentionally change any license terms, so
if you see one that changed, **it's a mistake**.

./crates/sqltest/standards/LICENSE # this one is an external library that we are not allowed to re-license
./LICENSE.txt # this is the root license
