Growing by one is a simpler, and often cheaper,
operation compared to appending one (newly created) zero value.
The method was introduced in Go 1.20.
growSlice in dec_helpers.go is left alone,
as it grows using the builtin append instead of reflect.Append.
No noticeable performance difference on any of our benchmarks,
as this code only runs for slices large enough to not fit in
saferio.SliceCap, and none of our benchmarks use data that large.

wireType itself is just a struct with seven pointer fields,
so an indirection doesn't feel necessary to noticeably reduce the amount
of memory that typeInfo takes for each Go type registered in gob.
The indirection does add a small amount of overhead though,
particularly one extra allocation when registering a type,
which is done a number of times as part of init.
For consistency, also update wireTypeUserInfo to not use a pointer.

Doing this work at init time does make the first encode or decode call
slightly faster, but the cost is still paid upfront.
However, not all programs which directly or indirectly import
encoding/gob end up encoding or decoding any values.
For example, a program might only be run with the -help flag,
or it might only use gob encoding when a specific mode is enabled.
Moreover, any work done at init time needs to happen sequentially and
before the main function can start, blocking the entire program.
Using benchinit, we see a moderate saving at init time:

The folded name logic (despite all attempts to optimize it)
was fundamentally an O(n) operation where every field in a struct
needed to be linearly scanned in order to find a match.
This made unmashaling of unknown fields always O(n).
Instead of optimizing the comparison for each field,
make it such that we can look up a name in O(1).
We accomplish this by maintaining a map keyed by pre-folded names,
which we can pre-calculate when processing the struct type.
Using a stack-allocated buffer, we can fold the input name and
look up its presence in the map.
Also, instead of mapping from names to indexes,
map directly to a pointer to the field information.
The memory cost of this is the same and avoids an extra slice index.
The new logic is both simpler and faster.

The Grow method is generally a more efficient way to grow a slice.
The older approach of using reflect.MakeSlice has to
waste effort zeroing the elements overwritten by the older slice
and has to allocate the slice header on the heap.

CodeUnmarshal 92.7k ± 0% 91.3k ± 0% -1.47%
CodeUnmarshalReuse 77.1k ± 0% 77.0k ± 0% -0.07%
The Code benchmarks (which are the only ones that uses slices)
are largely unaffected. There is a slight reduction in allocations.
A histogram of slice lengths from the Code testdata is as follows:
≤1: 392
≤2: 256
≤4: 252
≤8: 152
≤16: 126
≤32: 78
≤64: 62
≤128: 46
≤256: 18
≤512: 10
≤1024: 8
A bulk majority of slice lengths are 8 elements or under.
Use of reflect.Value.Grow performs better for larger slices since
it can avoid the zeroing of memory and has a faster growth rate.
However, Grow grows starting from 1 element,
with a 2x growth rate until some threshold (currently 512),
Starting from 1 ensures better utilization of the heap,
but at the cost of more frequent regrowth early on.
In comparison, the previous logic always started
with a minimum of 4 elements, which leads to a wasted capacity
of 75% for the highly frequent case of a single element slice.
The older code always had a growth rate of 1.5x,
and so wastes less memory for number of elements below 512.
All in all, there are too many factors that hurt or help performance.
Rergardless, the simplicity of favoring reflect.Value.Grow
over manually managing growth rates is a welcome simplification.

As part of the effort to rely less on bytes.Buffer,
switch most operations to use more natural append-like operations.
This makes it easier to swap bytes.Buffer out with a buffer type
that only needs to support a minimal subset of operations.
As a simplification, we can remove the use of the scratch buffer
and use the available capacity of the buffer itself as the scratch.
Also, declare an inlineable mayAppendQuote function to conditionally
append a double-quote if necessary.

There is a slight performance gain across the board due to

into the unused capacity of the underlying buffer,
avoiding an additional copy. See #53685

Unify these two methods as a single version that uses generics
to reduce duplicated logic. Unfortunately, we lack a generic
version of utf8.DecodeRune (see #56948), so we cast []byte to string.
The []byte variant is slightly slower for multi-byte unicode since
casting results in a stack-allocated copy operation.
Fortunately, this code path is used only for TextMarshalers.
We can also delete TestStringBytes, which exists to ensure
that the two duplicate implementations remain in sync.

There is a very slight performance degradation for CodeEncoder
due to an increase in allocation sizes. However, the number of allocations
did not change. This is likely due to remote effects of the growth rate
differences between bytes.Buffer and the builtin append function.
We shouldn't overly rely on the growth rate of bytes.Buffer anyways
since that is subject to possibly change in #51462.
As the benchtime increases, the alloc/op goes down indicating
that the amortized memory cost is fixed.

This is part of the effort to reduce direct reliance on bytes.Buffer
so that we can use a buffer with better pooling characteristics.
Avoid direct use of bytes.Buffer in Compact and Indent and
instead modify the logic to rely only on append.
This avoids reliance on the bytes.Buffer.Truncate method,
which makes switching to a custom buffer implementation easier.

There isn't document on what the behavior *should* be in this case.
Two possibilities:
1. Error dst has insufficient space (as done in this change)
2. Reduce the length of the decode to min(dst, src)
Option 1 was chosen because it seems the least surprising or

Avoid unnecessary allocations when calling reflect.TypeOf;
we can use nil pointers, which fit into an interface without allocating.
This saves about 1% of CPU time.
The builtin types are limited to typeIds between 0 and firstUserId,
and since firstUserId is 64, builtinIdToType does not need to be a map.
We can simply use an array of length firstUserId, which is simpler.
This saves about 1% of CPU time.
idToType is similar to firstUserId in that it is a map keyed by typeIds.
The difference is that it can grow with the user's types.
However, each added type gets the next available typeId,
meaning that we can use a growing slice, similar to the case above.
nextId then becomes the current length of the slice.
This saves about 1% of CPU time.
typeInfoMap is stored globally as an atomic.Value,
where each modification loads the map, makes a whole copy,
adds the new element, and stores the modified copy.
This is perfectly fine when the user registers types,
as that can happen concurrently and at any point in the future.
However, during init time, we sequentially register many types,
and the overhead of copying maps adds up noticeably.
During init time, use a regular global map instead,
which gets replaced by the atomic.Value when our init work is done.
This saves about 2% of CPU time.
Finally, avoid calling checkId in bootstrapType;
we have just called setTypeId, whose logic for getting nextId is simple,
so the extra check doesn't gain us much.
This saves about 1% of CPU time.
Using benchinit, which transforms GODEBUG=inittrace=1 data into Go
benchmark compatible output, results in a nice improvement:

The docs say:
If the input is at EOF, Decode returns io.EOF and does not modify e.
However, the added test fails:
--- FAIL: TestDecodePartial (0.00s)
encoder_test.go:1263: 31/81: expected io.ErrUnexpectedEOF: EOF
encoder_test.go:1263: 51/81: expected io.ErrUnexpectedEOF: EOF
In particular, the decoder would return io.EOF after reading a valid
message for a type specification, and then hit EOF before reading a data
item message.
Fix that by only allowing a Decode call to return io.EOF if the reader
hits EOF immediately, without successfully reading any message.
Otherwise, hitting EOF is an ErrUnexpectedEOF, like in other cases.
Also fix a net/rpc test that, coincidentally, expected an io.EOF
as an error when feeding bad non-zero data to a gob decoder.
An io.ErrUnexpectedEOF is clearly better in that scenario.
