http: restore h3 to working condition after connection filter introduction

Follow-up to dafdb20a26d0c

HTTP/3 needs a special filter chain, since it does the TLS handling
itself.

http: restore h3 to working condition after connection filter introduction

Follow-up to dafdb20a26d0c

HTTP/3 needs a special filter chain, since it does the TLS handling
itself. This PR adds special setup handling in the HTTP protocol handler
that takes are of it.

When a handler, in its setup method, installs filters, the default
behaviour for managing the filter chain is overridden.

sendf: change Curl_read_plain to wrap Curl_recv_plain

Prior to this change Curl_read_plain would attempt to read the
socket directly. On Windows that's a problem because recv data may be
cached by libcurl and that data is only drained using Curl_recv_plain.

Rather than rewrite Curl_read_plain to handle cached recv data, I
changed it to wrap Curl_recv_plain, in much the same way that
Curl_write_plain already wraps Curl_send_plain.

Curl_read_plain -> Curl_recv_plain
Curl_write_plain -> Curl_send_plain

This fixes a bug in the schannel backend where decryption of arbitrary
TLS records fails because cached recv data is never drained. We send
data (TLS records formed by Schannel) using Curl_write_plain, which
calls Curl_send_plain, and that may do a recv-before-send
("pre-receive") to cache received data. The code calls Curl_read_plain
to read data (TLS records from the server), which prior to this change
did not call Curl_recv_plain and therefore cached recv data wasn't
retrieved, resulting in malformed TLS records and decryption failure
(SEC_E_DECRYPT_FAILURE).

The bug has only been observed during Schannel TLS 1.3 handshakes. Refer
to the issue and PR for more information.

url: move back the IDN conversion of proxy names

Regression: in commit 53bcf55 we moved the IDN conversion calls to
happen before the HSTS checks. But the HSTS checks are only done on the
server host name, not the proxy names. By moving the proxy name IDN
conversions, we accidentally broke the verbose output showing the proxy
name.

This change moves back the IDN conversions for the proxy names to the
place in the code path they were before 53bcf55.

lib: feature deprecation warnings in gcc >= 4.3

Add a deprecated attribute to functions and enum values that should not
be used anymore.
This uses a gcc 4.3 dialect, thus is only available for this version of
gcc and newer. Note that the _Pragma() keyword is introduced by C99, but
is available as part of the gcc dialect even when compiling in C89 mode.

It is still possible to disable deprecation at a calling module compile
time by defining CURL_DISABLE_DEPRECATION.

Gcc type checking macros are made aware of possible deprecations.

Some testing support Perl programs are adapted to the extended
declaration syntax.

Several test and unit test C programs intentionally use deprecated
functions/options and are annotated to not generate a warning.

New test 1222 checks the deprecation status in doc and header files.
