As want is size_t, (file->buffer_pos - want) is unsigned, so checking
if it's less than zero makes no sense.
Check if file->buffer_pos is less than want instead to avoid the
unsigned integer wraparound.

test334: verify HTTP 204 response with chunked coding header

Verifies that a bodyless response don't parse this content-related
header.

http: don't parse body-related headers bodyless responses

Responses with status codes 1xx, 204 or 304 don't have a response body. For
these, don't parse these headers:

- Content

http: don't parse body-related headers bodyless responses

Responses with status codes 1xx, 204 or 304 don't have a response body. For
these, don't parse these headers:

- Content-Encoding
- Content-Length
- Content-Range
- Last-Modified
- Transfer-Encoding

This change ensures that HTTP/2 upgrades work even if a
"Content-Length: 0" or a "Transfer-Encoding: chunked" header is present.

http2: Stop drain from being permanently set on

Various functions called within Curl_http2_done() can have the
side-effect of setting the Easy connection into drain mode (by calling
drain_this()). However, the last time we unset this for a transfer (by
calling drained_transfer()) is at the beginning of Curl_http2_done().
If the Curl_easy is reused for another transfer, it is then stuck in
drain mode permanently, which in practice makes it unable to write any
data in the new transfer.

This fix moves the last call to drained_transfer() to later in
Curl_http2_done(), after the functions that could potentially call for a
drain.
