The splay tree is a tree where each easy handle can be added *once*. The
expire time for that node is the closest expire time for that easy
handle.
Easy handles can however have more expire times queued up, so when the
node is removed from the splay tree because it is the next in line to
take care of, we must check if there is another expire time in the queue
and then add the node back into the splay.
Failing to do the later part, the calling of add_next_timeout after
Curl_splaygetbest, would leave the state.expiretime on the previous time
stamp, which when could make the next call to Curl_splaygetbest use the
wrong time stamp and get a wrong node out, causing trouble.

Closes#18201
Make variants for transfers that send/receive or do both with just the
parameters they need. Split out the shutdown setting into a separate
function. Only FTP bothers with that.
Closes#18203
- assert instead of printing "internal error" for unlikely events
- avoid allocating the main struct
- convert globerror() from macro to function
- renames to shorter and clearer names
- malloc + copy => memdup0
- change buffer handling to dynbuf
- realloc to handle more globs, but use less memory for few
Closes#18198
The `connectdata` members `sockfd` and `writesockfd` needed to by either
CURL_SOCKET_BAD or a copy of one of `conn->sock[2]`. When equal to one,
that index was used to send/recv/poll the proper socket or connection
filter chain.
Replace those with `send_idx` and `recv_idx` which are either -1, 0 or 1
to indicate which socket/filter to send/receive on.
Closes#18179
When a HTTP version has been negotiated via ALPN, set the member
`conn->httpversion_seen` accordingly. This allows pending transfers to
reuse multiplexed http connections before the response to the first
transfer has arrived.

- Consistently keep options within ranges
- Reduce the maximum maxredirs value to fit a signed short
- Removed comments as the place to document the options is not here

Hold them for half the normal lifetime. Helps when told to transfer N
URLs in quick succession that all use the same non-resolving hostname.
Done by storing a DNS entry with a NULL pointer for 'addr'.
Previously an attempt was made in #12406 by Björn Stenberg that was
ultimately never merged.

In WebAssembly, using `TCP_NODELAY` fails with:
```
* Could not set TCP_NODELAY: Protocol not available
```
Add a new feature macro in `curl_setup.h` telling whether `TCP_NODELAY`
is known to be supported at runtime, when defined at compile-time.
Keep `TCP_NODELAY` guards at their current positions to ensure the
necessary headers (e.g. `netinet/tcp.h` and `netinet/in.h`) define it.

Adds `curl_off_t curl_multi_get_offt(CURLM *multi_handle, CURLMinfo_offt
info)` to the multi interface with enums:
* CURLMINFO_XFERS_CURRENT: current number of transfers
* CURLMINFO_XFERS_RUNNING: number of running transfers
* CURLMINFO_XFERS_PENDING: number of pending transfers
* CURLMINFO_XFERS_DONE: number of finished transfers to read
* CURLMINFO_XFERS_ADDED: total number of transfers added, ever
Add documentation for functions and info enums.
Add use in the curl command line tool to replace two static
variables counting the same "from the outside".

`getsock()` calls operated on a global limit that could
not be configure beyond 16 sockets. This is no longer adequate
with the new happy eyeballing strategy.
Instead, do the following:
- make `struct easy_pollset` dynamic. Starting with
a minimal room for two sockets, the very common case,
allow it to grow on demand.
- replace all protocol handler getsock() calls with pollsets
and a CURLcode to return failures
- add CURLcode return for all connection filter `adjust_pollset()`
callbacks, since they too can now fail.
- use appropriately in multi.c and multi_ev.c
- fix unit2600 to trigger pollset growth
Closes#18164
Makes curl follow redirects an act on the response code and change a

Potential future command line to send QUERY and following a redirect

Recently sometimes the Ubuntu package repository is very slow to access.
Remove the time limit for the install step, and bump the total limit,
aligning with Linux jobs.
In most cases the `install packages` steps takes 15-25 seconds.
Sometimes this goes up to 30-45 minutes.

Instead of using integer seconds. Also: if the cache contains over
30,000 entries after first pruning, it makes anoter round and removes
all entries that are older than half the age of the oldest entry until
it goes below 30,000.

To reduce log noise in local test runs:
- move the `buildinfo.txt` dump and header info lines
`OS:`, `Perl:`, `diff:` behind a `--ci` `runtests.pl` option.
- enable this option for the CI test targets.
- hide `Env:` header info line if empty.
- merge `Env:` output into a single `logmsg()` call.
Closes#18147
Also:
- GHA/linux, macos: test `install` with autotools too.
- GHA/linux, macos: enable fish and zsh completion in an autotools job.
- scripts: drop dynamic perl checks redundant after this patch.
- scripts: drop two interim variables.
- autotools: make `build-certs` target check perl first.
- autotools: replace `$(PERL)` with `@PERL@` to match the pattern used
in most automake scripts. For consistency. This makes `PERL` be
defined at configure-time, as opposed to make-time, for these cases
now.

Regression from 739ef9804d#13713Closes#18153

Add a case with 1 ipv4 and 3 ipv6 and check that all are attempted with

Before this patch there was no (easy) way to run tests without various
verbose options, hindering readability of the output due its length.
Unfortunately CMake reserves `test` as a target name, which was
the reason for its removal earlier. Re-add it with the name `tests`,
to have the functionality without the name collision.
Also add a `tests` target as an alias to `test` for autotools.

Some CURLOPT constants defined in the curl public headers were initially
enums (= ints), or macros with bare numeric values. Recent curl releases
upgraded them to `long` constants, to make them pass correctly to
`curl_easy_setop()` by default, i.e. without requiring a `(long)` cast.
This patch drops such casts from the examples embedded in the docs. At
the same time it documents which curl release made them `long` types,
to keep them useful when working with previous libcurl versions.
Also:
- drop a `(long)` cast that was never necessary.
- CURLOPT_ALTSVC_CTRL.md: bump local copy of macros to long.
- test1119: make it ignore symbols ending with an underscore, to skip
wildcard, e.g. `**CURLAUTH_***`.
