clang-tidy: avoid/silence bugprone-not-null-terminated-result
Prefer `sizeof()` over `strlen()`, static const variables over macros.
Add a couple of `NOLINT`s to silence false positives.

Also sync similar code patterns between libtests.

Cherry-picked from #20720

build: stop overriding standard memory allocation functions
Before this patch curl used the C preprocessor to override standard
memory allocation symbols: malloc, calloc, strdup, realloc, free.
The goal of these is to replace them with curl's debug wrappers in
`CURLDEBUG` builds, another was to replace them with the wrappers
calling user-defined allocators in libcurl. This solution needed a bunch
of workarounds to avoid breaking external headers: it relied on include
order to do the overriding last. For "unity" builds it needed to reset
overrides before external includes. Also in test apps, which are always
built as single source files. It also needed the `(symbol)` trick
to avoid overrides in some places. This would still not fix cases where
the standard symbols were macros. It was also fragile and difficult
to figure out which was the actual function behind an alloc or free call
in a specific piece of code. This in turn caused bugs where the wrong
allocator was accidentally called.

To avoid these problems, this patch replaces this solution with
`curlx_`-prefixed allocator macros, and mapping them _once_ to either
the libcurl wrappers, the debug wrappers or the standard ones, matching
the rest of the code in libtests.

This concludes the long journey to avoid redefining standard functions
in the curl codebase.

Note: I did not update `packages/OS400/*.c` sources. They did not
`#include` `curl_setup.h`, `curl_memory.h` or `memdebug.h`, meaning
the overrides were never applied to them. This may or may not have been
correct. For now I suppressed the direct use of standard allocators
via a local `.checksrc`. Probably they (except for `curlcl.c`) should be
updated to include `curl_setup.h` and use the `curlx_` macros.

This patch changes mappings in two places:
- `lib/curl_threads.c` in libtests: Before this patch it mapped to
  libcurl allocators. After, it maps to standard allocators, like
  the rest of libtests code.
- `units`: before this patch it mapped to standard allocators. After, it
  maps to libcurl allocators.

Also:
- drop all position-dependent `curl_memory.h` and `memdebug.h` includes,
  and delete the now unnecessary headers.
- rename `Curl_tcsdup` macro to `curlx_tcsdup` and define like the other
  allocators.
- map `curlx_strdup()` to `_strdup()` on Windows (was: `strdup()`).
  To fix warnings silenced via `_CRT_NONSTDC_NO_DEPRECATE`.
- multibyte: map `curlx_convert_*()` to `_strdup()` on Windows
  (was: `strdup()`).
- src: do not reuse the `strdup` name for the local replacement.
- lib509: call `_strdup()` on Windows (was: `strdup()`).
- test1132: delete test obsoleted by this patch.
- CHECKSRC.md: update text for `SNPRINTF`.
- checksrc: ban standard allocator symbols.

tests: make individual test sources compile cleanly
Tidy up headers and includes to ensure all individual test source
compile cleanly (but not link). To allow running clang-tidy (and
possibly other static analyzers) on them. It also improves readability
and allows to verify them locally, without the bundle logic.

clang-tidy ignores #included C files, so it's blind to bundle C files
the include these tests. The current workaround of embedding has
a couple of downsides:. meaningless filenames and line numbers,
missing issues, messing up self header paths. Thus, running it on
individual sources would be beneficial.

Also:
- de-duplicate includes.
- untangle some includes.
- formatting/indentation fixes.
- merge `getpart.h` into `first.h`.

tests: always make bundles, adapt build and tests
Make test bundles the default. Drop non-bundle build mode.
Also do all the optimizations and tidy-ups this allows, simpler builds,
less bundle exceptions, streamlined build mechanics.

Also rework the init/deinit macro magic for unit tests. The new method
allows using unique init/deinit function names, and calling them with
arguments. This is in turn makes it possible to reduce the use of global
variables.

Note this drop existing build options `-DCURL_TEST_BUNDLES=` from cmake
and `--enable-test-bundles` / `--disable-test-bundles` from autotools.

Also:
- rename test entry functions to have unique names: `test_<testname>`
  This removes the last exception that was handled in the generator.
- fix `make dist` to not miss test sources with test bundles enabled.
- sync and merge `tests/mk-bundle.pl` into `scripts/mk-unity.pl`.
- mk-unity.pl: add `--embed` option and use it when `CURL_CLANG_TIDY=ON`
  to ensure that `clang-tidy` does not miss external test C sources.
  (because `clang-tidy` ignores code that's #included.)
- tests/unit: drop no-op setup/stop functions.
- tests: reduce symbol scopes, global macros, other fixes and tidy-ups.
- tool1621: fix to run, also fix it to pass.
- sockfilt: fix Windows compiler warning in certain unity include order,
  by explicitly including `warnless.h`.

libtests: stop building the sames source multiple times
After this patch there is no more double/multiple compile of the same
libtest source under a different libtest ID. Each libtest is compiled
once, and changing behavior at runtime based on test ID.

- drop recently added physical clones for two prevously multi-compiled
  tests:
  - merge lib587 into lib554 again, branch at runtime.
  - merge lib645 into lib643 again, branch at runtime.

- replace existing dynamic branching to use `testnum` instead of
  a manually rolled `testno` based on an extra command-line argument.
  lib1571, lib1576.

- mk-bundle.pl: stop defining `LIB*` macros. No longer used.

- libtests: drop all `LIB*_C` guards.

- Make these tests branch at runtime, stop building copies:
  - lib585, based on lib500
  - lib565, based on lib510
  - lib529, based on lib525
  - lib527, lib532, based on lib526
  - lib545, based on lib544
  - lib548, based on lib547
  - lib696, based on lib556
  - lib584, based on lib589
  - lib1539, based on lib1514
  - lib1543, based on lib1518
  - lib1917, based on lib1916
  - lib1946, based on lib1940
  - lib671, 672, 673, based on lib670

tests: drop mk-bundle exceptions
Using a mixture of techniques to avoid symbols collisions:
- reduce scope.
- add `t*_` / `T*_` prefix.
- move shared functions to `testutil.c`.
  (`suburl()`, `rlim2str()`)
- clone re-used lib*.c sources.
  (lib587, lib645)
- include shared symbols just once in re-used `lib*.c` sources.
  (using `LIB*_C` guards.)
- drop re-used `lib*.c` sources where they were identical or
  unused.
- make macros global.
- #undef macros before use.

What remain is the entry functions `test`, and `unit_setup`,
`unit_stop` in unit tests.

Also:
- fix formatting and other minor things along the way.
- add `const` where possible.
- sync some symbol names between tests.
- drop `mk-bundle-hints.sh` that's no longer necessary.

curlx: move into to curlx/
Move curlx_ functions into its own subdir.

The idea is to use the curlx_ prefix proper on these functions, and use
these same function names both in tool, lib and test suite source code.
Stop the previous special #define setup for curlx_ names.

The printf defines are now done for the library alone. Tests no longer
use the printf defines. The tool code sets its own defines. The printf
functions are not curlx, they are publicly available.

The strcase defines are not curlx_ functions and should not be used by
tool or server code.

dynbuf, warnless, base64, strparse, timeval, timediff are now proper
curlx functions.

When libcurl is built statically, the functions from the library can be
used as-is. The key is then that the functions must work as-is, without
having to be recompiled for use in tool/tests. This avoids symbol
collisions - when libcurl is built statically, we use those functions
directly when building the tool/tests. When libcurl is shared, we
build/link them separately for the tool/tests.

multi: init_do(): check result
Calls to `Curl_init_do()` did not check on result and missed failures to
properly and completely initialize a transfer request.

The main cause of such an init failure is the need to rewind the
READFUNCTION without a SEEKFUNCTION registered. Check the failure to
"rewind" the upload data immediately make test cases 1576 and friends
fail.

lib: add CURLFOLLOW_OBEYCODE and CURLFOLLOW_FIRSTONLY
With this change, the argument passed to the CURLOPT_FOLLOWLOCATION
option is now instead a "mode" instead of just a boolean. Documentation
is extended to describe the two new modes.
