DECODE-BASE64-STREAM-TO-SEQUENCE is the only thing that requires
anything fancy: We read into an adjustable array. Alternative could be
using REDIRECT-STREAM and WITH-OUTPUT-TO-STRING, but that is likely
slower (untested).
Test cases are kept for now to confirm that qbase64 is conforming to our
expectations, but can probably dropped in favor of a few more sample
messages in the test suite.
:START and :END are sadly no longer supported and need to be replaced by
SUBSEQ.

Eventually, we'll want to replace dump-stream-binary with something more
efficient—given that we have flexi-streams we can use something that
only does matching element types no problem. REDIRECT-STREAM is much
more efficient thanks to using an internal buffer.
streams.lisp gets a new section at the beginning for grouping utilities
that don't have any real (internal) dependencies.

The input adapter streams were input streams yielding either binary or
character data that could be constructed from a variable data source.
The stream would take care not to destroy the underlying data
source (i.e. not close it if it was a stream), so similar to with
FILE-PORTIONs, but simpler.
Unfortunately, the implementation was quite inefficient: They are
ultimately defined in terms of a function that retrieves the next
character in the source. This only allows for an implementation of
READ-CHAR (and READ-BYTE). Thanks to cl/8559, READ-SEQUENCE can be used
on e.g. FILE-PORTION, but this was still negated by a input adapter
based on one—then, READ-SEQUENCE would need to fall back on READ-CHAR or
READ-BYTE again.
Luckily, we can replace BINARY-INPUT-ADAPTER-STREAM and
CHARACTER-INPUT-ADAPTER-STREAM with a much simpler abstraction: Instead
of extra stream classes, we have a function, MAKE-INPUT-ADAPTER, which
returns an appropriate instance of FLEXI-STREAM based on a given source.
This way, the need for a distinction between binary and character input
adapter is eliminated, since FLEXI-STREAMS supports both binary and
character reads (external format is not yet handled, though).
Consequently, the :binary keyword argument to MIME-BODY-STREAM can be
dropped.
flexi-streams provides stream classes for everything except a stream
that doesn't close the underlying one. Since we have already implemented
this in POSITIONED-FLEXI-INPUT-STREAM, we can split this functionality
into a new superclass ADAPTER-FLEXI-INPUT-STREAM.
This change also allows addressing the performance regression
encountered in cl/8559: It seems that flexi-streams performs worse when
we are reading byte by byte or char by char. (After this change mblog is
still two times slower than on r/6150.) By eliminating the adapter
streams, we can start utilizing READ-SEQUENCE via decoding code that
supports it (i.e. qbase64) and bring performance on par with r/6150
again. Surely there are also ways to gain back even more performance
which has to be determined using profiling. Buffering more aggressively
seems like a sure bet, though.
Switching to flexi-streams still seems like a no-brainer, as it allows
us to drop a lot of code that was quite hacky (e.g. DELIMITED-INPUT-
STREAM) and implements en/decoding handling we did not support before,
but would need for improved correctness.

This refactor is driven by the following (ultimate) aims:
- Get rid of as much of the custom stream code in mime4cl which makes
less code to maintain in the future.
- Lay the groundwork for correct handling of 8bit transfer encoding:
The mime4cl we inherited assumes that any MIME message can be decoded
completely by the CL implementation (in SBCL's case using latin1)
into CHARACTERs. This is not necessarily the case. flexi-streams
allows changing how the stream is decoded on the fly and also has
support for reading the underlying bytes which is perfect for the
requirements decoding MIME has.
- Since flexi-streams uses trivial-gray-streams, it supports
READ-SEQUENCE. Taking advantage of this may improve decoding
performance significantly in the future.
This incurs the following changes:
- Naturally we now open given files as binary files in MIME-MESSAGE.
Given strings are encoded using STRING-TO-OCTETS and then passed on
to a new octet vector method. Instead of MY-STRING-INPUT-STREAM this
now uses flexi-streams' WITH-INPUT-FROM-SEQUENCE.
- OPEN-FILE-PORTION and OPEN-DECODED-FILE-PORTION need to be merged,
since the transfer encoding not only implies an extra decoder stream
that needs to be attached after file portion stream, but also imply a
certain encoding of the stream itself (mostly binary vs. ASCII).
As flexi-streams can change their encoding on the fly this could be
untangled again, but it is not strictly necessary.
As before, we use the DATA slot of the file portion to create a fresh
stream if possible. Instead of strings we now use an vector of octets
to match MIME-MESSAGE.
The actual portioned stream relies on POSITIONED-FLEXI-INPUT-STREAM, a
subclass of the stock FLEXI-INPUT-STREAM class, described below.
- POSITIONED-FLEXI-INPUT-STREAM replaces DELIMITED-INPUT-STREAM. It is
created using MAKE-POSITIONED-FLEXI-INPUT-STREAM which accepts the
same arguments as MAKE-FLEXI-STREAMS and, additionally, :IGNORE-CLOSE.
A POSITIONED-FLEXI-INPUT-STREAM works the same as an
FLEXI-INPUT-STREAM, but upon creation, the underlying stream is
rewinded or forwarded to the argument given by :POSITION using
FILE-POSITION.
If :IGNORE-CLOSE is T, a call to CLOSE is not forwarded to the
underlying stream.

Whether chunking is involved or not, is an implementation detail of each
Blobstore. Consumers of a whole blob shouldn't need to worry about that.
It currently is not visible in the gRPC interface either. It
shouldn't bleed into everything.
Let the BlobService trait provide `open_read` and `open_write` methods,
which return handles providing io::Read or io::Write, and leave the
details up to the implementation.
This means, our custom BlobReader module can go away, and all the
chunking bits in there, too.
In the future, we might still want to add more chunking-aware syncing,
but as a syncing strategy some stores can expose, not as a fundamental
protocol component.
This currently needs "SyncReadIntoAsyncRead", taken and vendored in from
https://github.com/tokio-rs/tokio/pull/5669.
It provides a AsyncRead for a sync Read, which is necessary to connect
our (sync) BlobReader interface to a GRPC server implementation.
As an alternative, we could also make the BlobReader itself async, and
let consumers of the trait (EvalIO) deal with the async-ness, but this
is less of a change for now.
In terms of vendoring, I initially tried to move our tokio crate to
these commits, but ended up in version incompatibilities, so let's
vendor it in for now.

point to the blobs we actually want to render, and having some data left

The idea is to replace the char by char base64 decoder with one that
supports read-sequence. After that deliminited-input-stream needs to
gain support for read-sequence as well, so we can actually take
advantage of this fact. Finally, we'll have to evaluate the remaining
