94e30a756e std: fix a bunch of typos
The majority of these are in comments, some in doc comments which might
affect the generated documentation, and a few in parameter names -
nothing that should be breaking, however.

a5c910adb6 change semantics of @memcpy and @memset
Now they use slices or array pointers with any element type instead of
requiring byte pointers.

This is a breaking enhancement to the language.

The safety check for overlapping pointers will be implemented in a
future commit.

GPA: Catch invalid frees
* GPA: Catch invalid frees

Fix #14791: Catch cases where an invalid slice is passed to free().
This was silently ignored before but now logs an error. This change
uses a AutoHashMap to keep track of the sizes which seems to be an
overkill but seems like the easiest way to catch these errors.

* GPA: Add wrong alignment checks to free/resize

Implement @Inkryption's suggestion to catch free/resize with the wrong
alignment. I also changed the naming to match large allocations.

3c2a43fdcc Revert "std: check types of pointers passed to allocator functions"
This reverts commit abc9530a88d24350481d9264edcde300f293929a.

This patch implies that the idiomatic Zig way of handling anytype
parameter is to write a bunch of boilerplate instead of directly
accessing type information and relying on the compiler to be useful.

I don't want it to be this way.

It is the compiler's job to make useful error messages when the wrong
field of a type info result is accessed, and it is the zig programmer's
job to understand what it means when a compile error points at the field
access of `@typeInfo` (along with the relevant callsites).

One thing that might be useful would be having the compiler be aware of
module boundaries and highlighting the boundaries of them. The first
reference note after crossing a module boundary is likely the most
interesting one.

Fixes a regression introduced in

resizing fails.

7f063b2c52 WasmAllocator: simplify thanks to new Allocator interface
Now it can refuse to resize when it would disturb the metadata tracking
strategy, resulting in smaller code size, a simpler implementation, and
less fragmentation.

e2e60f5ff9 std.heap.WasmAllocator: redo
The previous version had a fatal flaw: it did ensureCapacity(1) on the
freelist when allocating, but I neglected to consider that you could
free() twice in a row. Silly!

This strategy allocates an intrusive freelist node with every
allocation, big or small. It also does not have the problems with resize
because in this case we can push the upper areas of freed stuff into the
corresponding freelist.

Make invalidFmtError public and use in place of compileErrors for bad format strings (#13526)
* Export invalidFmtErr

To allow consistent use of "invalid format string" compile error
response for badly formatted format strings.

See https://github.com/ziglang/zig/pull/13489#issuecomment-1311759340.

* Replace format compile errors with invalidFmtErr

- Provides more consistent compile errors.
- Gives user info about the type of the badly formated value.

* Rename invalidFmtErr as invalidFmtError

For consistency. Zig seems to use “Error” more often than “Err”.

* std: add invalid format string checks to remaining custom formatters

* pass reference-trace to comp when building build file; fix checkobjectstep

008b0ec5e5 std.Thread.Mutex: change API to lock() and unlock()
This is a breaking change. Before, usage looked like this:

```zig
const held = mutex.acquire();
defer held.release();
```

Now it looks like this:

```zig
mutex.lock();
defer mutex.unlock();
```

The `Held` type was an idea to make mutexes slightly safer by making it
more difficult to forget to release an aquired lock. However, this
ultimately caused more problems than it solved, when any data structures
needed to store a held mutex. Simplify everything by reducing the API
down to the primitives: lock() and unlock().

f7b090d707 std.log: simplify to 4 distinct log levels
Over the last year of using std.log in practice, it has become clear to
me that having the current 8 distinct log levels does more harm than
good. It is too subjective which level a given message should have which
makes filtering based on log level weaker as not all messages will have
been assigned the log level one might expect.

Instead, more granular filtering should be achieved by leveraging the
logging scope feature. Filtering based on a combination of scope and log
level should be sufficiently powerful for all use-cases.

Note that the self hosted compiler has already limited itself to 4
distinct log levels for many months and implemented granular filtering
based on both log scope and level. This has worked very well in practice
while working on the self hosted compiler.
