Also:
- support per-directory and per-upper-directory whitelist entries.
- convert badlist input grep tweak into the above format.
(except for 'And' which had just a few hits.)
- fix many code exceptions, but do not enforce.
(there also remain about 350 'will' uses in lib)
- fix badwords in example code, drop exceptions.
- badwords-all: convert to Perl.
To make it usable from CMake.
- FAQ: reword to not use 'will'. Drop exception.
Closes#20886
Backtrack on previous change that aimed to solve the wrong `share.h`
being included. It turns out it did not fix this issue. At the same time
it introduced relative header filenames and the need to include the same
headers differently depending on the source files' location, reducing
readability and editability.
Replace this method by re-adding curl's lib source directory to the
header path and addressing headers by the their full, relative name to
that base directory. Aligning with this method already used in src and
tests.
With these advantages:
- makes includes easier to read, recognize, grep, sort, write, and copy
between sources,
- syncs the way these headers are included across curl components,
- avoids the ambiguity between system `schannel.h`, `rustls.h` vs.
local headers using the same names in `lib/vtls`,
- silences clang-tidy `readability-duplicate-include` checker, which
detects the above issue,
Ref: https://clang.llvm.org/extra/clang-tidy/checks/readability/duplicate-include.html
- possibly silences TIOBE coding standard warnings:
`6.10.2.a: Don't use relative paths in #include statements.`
- long shot: it works well with concatenated test sources, for
clang-tidy-friendly custom unity builds. Ref: #20667
Slight downside: it's not enforced.
If there happens to be a collision between a local `lib/*.h` header and
a system one, the solution is to rename (possibly with its `.c`
counterpart) into the `curl_` namespace. This is also the method used by
curl in the past.
Also:
- curlx/inet_pton: reduce scope of an include.
- toolx/tool_time: apply this to an include, and update VS project
files accordingly. Also dropping unnecessary lib/curlx header path.
- clang-tidy: enable `readability-duplicate-include`.

- asyn-thrdd.c: scope an include.
- apply more clang-format suggestions.
- tidy-up PP guard comments.
- delete empty line from the top of headers.
- add empty line after `curl_setup.h` include where missing.

Also:
- vquic-tls.h: do not include unused headers for non-H3 builds.
- autotools: stop looking for `openssl/x509.h` header.
- cmp-config.pl: delete exception for `openssl/x509.h`.
- examples: format/comment sync between the two touched files.
- openssl: drop unused `curlx/wait.h` include.

Replace the old Curl_ssl_get_internals() with a new connection filter
query to retrieve the information. Implement that filter query for TCP
and QUIC TLS filter types.
Add tests in client tls_session_reuse to use the info option and check
that pointers are returned.

Fixes#17801Closes#17809
by including headers using "../[header]" when done from C files in
subdirectories, we do not need to specify the lib source dir as an
include path and we reduce the risk of header name collisions with
headers in the SDK using the same file names.

Enable TLS Early Data for wolfSSL:
- merge WOLFSSL_CTX and WOLFSSL setup from ngtcp2 with the general
implemenation in wolfssl.c
- enable for QUIC via ngtcp2
- give Curl_vquic_tls_init() a `struct alpn_spec` like used for the TCP
case. Adapt gnutls and other users.
- enable pytest test cases for early data with wolfSSL
and while this messes up wolfssl.c anyway, do
- rename all struct/functions with prefix 'wolfssl_' to 'wssl_' to not
pollute that name prefix
- rename `ctx/handle` to `ssl_ctx/ssl`, as used in openssl case
Closes#16167
When a QUIC TLS session announced early data support and
'CURLSSLOPT_EARLYDATA' is set for the transfer, send initial request and
body (up to the 128k we buffer) as 0RTT when curl is built with
ngtcp2+gnutls.
QUIC 0RTT needs not only the TLS session but the QUIC transport
paramters as well. Store those and the earlydata max value together with
the session in the cache.
Add test case for h3 use of this. Enable quic early data in nghttpx for
testing.
Closes#15667
Described in detail in internal doc TLS-SESSIONS.md
Main points:
- use a new `ssl_peer_key` for cache lookups by connection filters
- recognize differences between TLSv1.3 and other tickets
* TLSv1.3 tickets are single-use, cache can hold several of them for a peer
* TLSv1.2 are reused, keep only a single one per peer
- differentiate between ticket BLOB to store (that could be persisted) and object instances
- use put/take/return pattern for cache access
- remember TLS version, ALPN protocol, time received and lifetime of ticket
- auto-expire tickets after their lifetime
Closes#15774
Before this patch `lib/curl_setup.h` defined these two macros right
next to each other, then the source code used them interchangeably.
After this patch, `USE_HTTP3` guards all HTTP/3 / QUIC features.
(Like `USE_HTTP2` does for HTTP/2.) `ENABLE_QUIC` is no longer used.
This patch doesn't change the way HTTP/3 is enabled via autotools
or CMake. Builders who enabled HTTP/3 manually by defining both of
these macros via `CPPFLAGS` can now delete `-DENABLE_QUIC`.
Closes#13352
