cmake: replace internal option with a new testbins target
To allow building test binaries without test certs, replacing
`_CURL_SKIP_BUILD_CERTS` internal option with a build target that is
similar to `testdeps`, but without building the test certificates.

To make building test binaries a little bit faster, with less noisy
output, and without having to reconfigure the build.

cmake: add native clang-tidy support for tests, with concatenated sources
Tests are build in "unity"-style, by including sources into an umbrella
C files (similar to how CMake unity works). This does not play well with
clang-tidy, which seems to unconditionally ignore C sources included
like this. To fix it, curl's CMake implements a manual clang-tidy
support for tests, which  compiles sources one-by-one, while also making
sure sources compile cleanly standalone (e.g. all sources need to
include `first.h`). The manual clang-tidy implementation is fragile, and
performance, in particular when targeting Windows, is abysmal.

This patch introduces an alternate solution, enabled by the
`_CURL_TESTS_CONCAT=ON` option. In this mode, umbrella sources include
the actual sources instead of `#including` them. Allowing to use CMake's
built-in clang-tidy support to compile them, with clang-tidy actually
checking the sources. Making the manual clang-tidy support unnecessary.
In the Windows CI job it results in a 4x performance improvement (4m ->
1m), making it practical to run clang-tidy on tests on Windows, in CI.

The main downside is that clang-tidy doesn't understand the `#line`
directive. Meaning issues found show the wrong filename and line number
next to them. It's not impossible to locate errors this way, but also
not convenient.

Minor/potential downside is that the concatenated source needs to be
reassembled each time an original source is updated. This may result in
more copying on the disk when used in local development. The largest
source is 1.4MB, so probably not a show-stopper on most machines.

Another is the complexity of maintaining two methods in parallel, which
may be necessary till clang-tidy understands `#line`:
https://github.com/llvm/llvm-project/issues/62405

This solution may in theory also enable adding clang-tidy support for
tests in autotools, though I haven't tried.

Targeted for curl CI for now, and used in a GHA/windows job. 100%
experimental, not recommended outside these.

build: fully omit verbose strings and code when disabled
When the compiler supports C99.

- map logging functions to macro stubs when verbose logging is disabled
  and the compiler is C99. Make sure these stubs silence unused variable
  warnings for non-variadic arguments.
  Before this patch they mapped to function stubs, the same codepath
  used for C89 compiler in this configuration.

- introduce new macros to tell the compiler which code to include
  when verbose code is active, or inactive:

  - `CURLVERBOSE`: defined when verbose code is active.
    To enclose blocks of code only used for verbose logging.

  - `VERBOSE(statement);`:
    compile statement when verbose code is active.
    To mark code lines only used for verbose logging.

  - `NOVERBOSE(statement);`:
    compile statement when verbose code is inactive.
    To suppress warnings for arguments passed to logging functions via
    printf masks, e.g. `NOVERBOSE((void)ipaddress);`, yet keeping
    the warning in verbose builds.

  Note these macros are not the same as `CURL_DISABLE_VERBOSE_STRINGS`.
  Verbose code is always active in C89 mode (without variadic macro
  support).

- drop existing uses of `CURL_DISABLE_VERBOSE_STRINGS` where redundant,
  or replace with the above macros. Ending up reducing the number of
  `#ifdef`s, and also the number of lines.

timeout handling: auto-detect effective timeout
When checking a transfer for being expired via `Curl_timeleft_ms()`,
eleminate the `bool connecting` parameter and have the function check
the `mstate` of the transfer instead.

Advantages:
* eleminate the caller needing awareness if the transfer is
  connecting or in a later state
* fix pingpong timeout handling to check the correct timeout
  during "proto_connect" phases
* avoid using "connecting" timeouts during establishing a secondary
  connection (e.g. FTP) since this would use the timestamp from
  the original, primary connect and thus be wrong

build: merge TrackMemory (CURLDEBUG) into debug-enabled option
Drop separate `TrackMemory` (aka `CURLDEBUG`) debug feature.

After recent changes (thread-safety,
193cb00ce9, and updates leading up to
it), `TrackMemory` is unlikely to cause build or runtime issues.

To simplify builds and debug options, enable `TrackMemory`
unconditionally for debug-enabled (aka `DEBUGBUILD`) builds. Before
this patch, this was already the default, with an option to disable
it, or enable it in non-debug-enabled builds.

Note, in practice these two debug options already went hand in hand. It
was not possible to toggle them separately for a long time due to bugs,
before 59dc9f7e69 (2024-05-28) fixed it.

This patch also removes/deprecates separate knobs and feature flags for
`TrackMemory`:
- autotools: `--enable-curldebug`/`--disable-curldebug`
- cmake: `-DENABLE_CURLDEBUG=ON`/`OFF`
- C macro: `CURLDEBUG`
- libcurl: `CURL_VERSION_CURLDEBUG` symbol deprecated in favor
  of `CURL_VERSION_DEBUG`. They always return the same value after this
  patch.

Also:
- drop `TrackMemory` from `curl -V` output.
- rename internal `CURLDEBUG` macro to `CURL_MEMDEBUG` internally.
  To avoid confusion with `DEBUGBUILD`, but to keep guarding
  `TrackMemory`-related internals for readability.
- runtests: bind `TrackMemory` to debug feature. Keep it a separate
  test feature requirement, for clarity.
- CI: drop test builds for combinations of the two options.
- GHA/linux: no longer disable TrackMemory in the TSAN job.

ratelimit: download finetune
When a download size is known and rate limiting is in effect, adjust the
duration of each measurement step and its rate for maximum precision.

Since it is unpredictable how long the last bytes of a download will
take, download speed can be thrown off if the "last bytes" are a
significant amount of the total download. Make the "last bytes" small in
comparision to the rest and "stretch" the rate limit intervals to
accommodate the difference.

Fix ngtcp2 receive data acknowldgements to be based on a local window
size tracking. This allows window updates controlled by rate limits.

Fix ratelimit wait time calculation to accomodate negative tokens.

h3 rate limit, update timeers

Make download rate limits work correctly in ngtcp2. Fix multi handling
of rate limits to set a timer for when limits will update again.

Without running the transfer on limit updates, protocols like h2/h3 may
stall if the server does not send due to stream windows being too small.

scorecard: measure download speedlimits

When running scorecard with --limit-rate=n, show the reported download
speed averages plus percentage deviation from the limit.

lib: remove uses of PRIu32 by adding "hack" for DJGPP
Avoid using PRIu32 and PRId32 in product source code. We don't need it.
It reduces readability. It is also inconsistent since unsigned int has
the same size and does not require the define.

DJGPP warns about using %u for uint32_t by default because it seems to
typedef it to unsigned long instead of unsigned int. Which even that is
annoying since long and int are both 32 bit on this platform.

We use our own *printf() implementation and we know this is safe.

This work-around defines uint32_t for DJGPP into unsigned int to avoid
the warnings and thus the need to use PRIu32 and PRId32.

progress: narrower time display, multiple fixes
- Each time field is now 7 characters wide, so that the total width
  never exceeds 79 columns so that it works correctly also in Windows
  terminals. The title lines are adjusted accordingly.

  This is accomplished by using h:mm:ss style up to 10 hours, and for
  longer periods switch to "nnX nnY" style output. For hours, days,
  months and years.

  For less than one hour, the hour field is now dropped.

  When no time info is provided, the field is now space-only. No more
  `-:--:--`.

  Also fixed the output for really long times which previously was
  completely broken. The largest time now shows as ">99999y". (Becase
  I can't figure out a better way).

- For sizes, the widths are now properly fixed to 6 characters. When
  displaying a unit with less than 3 digits, it shows two decimal
  precision like "16777215 => 15.99M" and one decmal otherwise: "262143
  => 255.9k"

  Also fixes the decimal math. 131071 is 127.9k, which it previously did
  not show.

- The time and size field outputs are now properly verified in test
  1636.

Use `data->progress.now` as the timestamp of proecssing a transfer.
Update it on significant events and refrain from calling `curlx_now()`
in many places.

The problem this addresses is
a) calling curlx_now() has costs, depending on platform. Calling it
   every time results in 25% increase `./runtest` duration on macOS.
b) we used to pass a `struct curltime *` around to save on calls, but
   when some method directly use `curx_now()` and some use the passed
   pointer, the transfer experienes non-linear time. This results in
   timeline checks to report events in the wrong order.

By keeping a timestamp in the easy handle and updating it there, no
longer invoking `curlx_now()` in the "lower" methods, the transfer
can observer a steady clock progression.

Add documentation in docs/internals/TIME-KEEPING.md

bufref: rename *memdup() to *memdup0()
To make it clearer to readers of the code that the resulting dup also
has a null terminator. Something a "normal" memdup() does not provide.
