transfer: cleanup done+excess handling
- add `SingleRequest->download_done` as indicator that
  all download bytes have been received
- remove `stop_reading` bool from readwrite functions
- move excess body handling into client download writer

transfer: readwrite improvements
- changed header/chunk/handler->readwrite prototypes to accept `buf`,
  `blen` and a `pconsumed` pointer. They now get the buffer to work on
  and report back how many bytes they consumed
- eliminated `k->str` in SingleRequest
- improved excess data handling to properly calculate with any body data
  left in the headerb buffer
- eliminated `k->badheader` enum to only be a bool

misc: fix -Walloc-size warnings
GCC 14 introduces a new -Walloc-size included in -Wextra which gives:

```
src/tool_operate.c: In function ‘add_per_transfer’:
src/tool_operate.c:213:5: warning: allocation of insufficient size ‘1’ for type ‘struct per_transfer’ with size ‘480’ [-Walloc-size]
  213 |   p = calloc(sizeof(struct per_transfer), 1);
      |     ^
src/var.c: In function ‘addvariable’:
src/var.c:361:5: warning: allocation of insufficient size ‘1’ for type ‘struct var’ with size ‘32’ [-Walloc-size]
  361 |   p = calloc(sizeof(struct var), 1);
      |     ^
```

The calloc prototype is:
```
void *calloc(size_t nmemb, size_t size);
    ```

So, just swap the number of members and size arguments to match the
prototype, as we're initialising 1 struct of size `sizeof(struct
...)`. GCC then sees we're not doing anything wrong.

RTSP: improved RTP parser
- fix HTTP header parsing to report incomplete
  lines it buffers as consumed!
- re-implement the RTP parser for interleave RTP
  messages for robustness. It is now keeping its
  state at the connection
- RTSP protocol handler "readwrite" implementation
  now tracks if the response is before/in/after
  header parsing or "in" a bod by calling
  "Curl_http_readwrite_headers()" itself. This
  allows it to know when non-RTP bytes are "junk"
  or HEADER or BODY.
- tested with #12035 and various small receive
  sizes where current master fails

http: do not require a user name when using CURLAUTH_NEGOTIATE
In order to get Negotiate (SPNEGO) authentication to work in HTTP you
used to be required to provide a (fake) user name (this concerned both
curl and the lib) because the code wrongly only considered
authentication if there was a user name provided, as in:

  curl -u : --negotiate https://example.com/

This commit leverages the `struct auth` want member to figure out if the
user enabled CURLAUTH_NEGOTIATE, effectively removing the requirement of
setting a user name both in curl and the lib.

Introduce a --enable-form-api configure option to control its inclusion

Form api code is dependent of MIME: configure and CMake handle this
dependency automatically: CMake by making it a dependent option
explicitly, configure by inheriting the MIME value by default and
rejecting explicit incompatible values.

"form-api" is now a new hidden test feature.

Update libcurl modules to respect this option and adjust tests
accordingly.

lib: add bufq and dynhds
Adding `bufq`:
- at init() time configured to hold up to `n` chunks of `m` bytes each.
- various methods for reading from and writing to it.
- `peek` support to get access to buffered data without copy
- `pass` support to allow buffer flushing on write if it becomes full
- use case: IO buffers for dynamic reads and writes that do not blow up
- distinct from `dynbuf` in that:
  - it maintains a read position
  - writes on a full bufq return CURLE_AGAIN instead of nuking itself
- Init options:
  - SOFT_LIMIT: allow writes into a full bufq
  - NO_SPARES: free empty chunks right away
- a `bufc_pool` that can keep a number of spare chunks to
  be shared between different `bufq` instances

Adding `dynhds`:
- a straightforward list of name+value pairs as used for HTTP headers
- headers can be appended dynamically
- headers can be removed again
- headers can be replaced
- headers can be looked up
- http/1.1 formatting into a `dynbuf`
- configured at init() with limits on header counts and total string
  sizes
- use case: pass a HTTP request or response around without being version
  specific
- express a HTTP request without a curl easy handle (used in h2 proxy
  tunnels)
- future extension possibilities:
  - conversions of `dynhds` to nghttp2/nghttp3 name+value arrays

CURLOPT_PIPEWAIT: allow waited reuse also for subsequent connections
As tested in test_02_07, when firing off 200 urls with --parallel, 199
wait for the first connection to be established. if that is multiuse,
urls are added up to its capacity.

The first url over capacity opens another connection. But subsequent
urls found the same situation and open a connection too. They should
have waited for the second connection to actually connect and make its
capacity known.

This change fixes that by

- setting `connkeep()` early in the HTTP setup handler. as otherwise
  a new connection is marked as closeit by default and not considered
  for multiuse at all
- checking the "connected" status for a candidate always and continuing
  to PIPEWAIT if no alternative is found.

pytest:
- removed "skip" from test_02_07
- added test_02_07b to check that http/1.1 continues to work as before
