libroot: Disable -Werror and re-enable safeClone usage.

This code depends on the inline buffer being used at
the moment. Eventually we should refactor it, but for
now, just use the deprecated method.

Should fix regressions following ICU upgrade.

icu: bump OS (and all dependencies) to ICU 74

* Non-x86 will likely break until they get an updated icu74
build-package

Prepare for ICU update

- libicule and libiculx do not exist anymore in newer ICU versions
(harfbuzz replaces them), but we didn't actually use them, so remove
them from the build feature and from the package dependencies
- Add namespace usage marcos since the newer ICU packages put ICU things
in a namespace, making it easier to have multiple versions of ICU used
side by side.

No functional change intended, but this makes it possible to build the
code with either ICU 57 (for gcc2) or 66 (for other architectures).

MultibyteToWchar: correctly handle UTF-16 surrogate pairs.

* Whilst in WcharToMultibyte, we correctly convert our UTF-32
wchar characters to multibyte, the same wasn't done in
MultibyteToWchar. Now, if we detect a leading surrogate,
we'll re-read the multibyte sequence with space for a UTF-16
pair, which allows U16_GET to correctly convert the UTF-16
byte sequence into the needed UTF-32 codepoint.

Fixes #13184.

ICUCtypeData.cpp: format string fixes for tracing.

ICU add-on: validate mbState->converter before attempting to close.

This resolves crashes in gawk with multibyte support.

Fixes #12515, #13103.

Adjust mbstate_t to embed the state of the ICU converter.

* make room in mbstate_t for containing an ICU-converter's state
(well, in fact the whole converter object)
* adjust libroot's locale add-on to clone converters into a given
mbstate_t directly
* adjust ICUThreadLocalStorageValue to contain the converter pointer
instead of a converter-ID (if the converter is related to an
mbstate_t, it points into the mbstate_t).
* adjust users of converters to directly use converter pointers
instead of ICUConverterRef
* drop now unused ICUConverterManager and ICUConverterRef
* update gcc4 optional package

This brings our multibyte implementation into a fully working state,
both non-ascii and non-8-bit characters can now be handled normally
in the Terminal, i.e. this finally fixes #6276.

N.B.: Since the size of mbstate_t has changed, everything (including
the compiler!) needs to be rebuilt.

Fix gcc4-build and handling of src-pointer upon error.

* the reference to MB_CUR_MAX requires stdlib.h
* if an conversion error occurs, the returned src pointer must point to
the character that triggered the error

Implement our own version of wcsrtombs().

* add WcharStringToMultibyte() to libroot's locale backend
* implement wcstombs(), wcsrtombs() and wcsnrtombs() on top of that
new backend function

Add implementation of mbsrtowcs() to our locale backend.

* add MultibyteStringToWchar() to ICU locale backend
* implement mbsrtowcs() and mbsnrtowcs() on top of
MultibyteStringToWchar()
* drop respective glibc files

Reset ICU-converter in case of error.

Add tracing to some locale backend functions.

Bring rewritten multibyte-support into repository.

* update copyrights of locale backend files

Multibyte-support has been rewritten to use ICU as backend.
While this does not necessarily work properly in every aspect
(e.g. the shell still has [different] problems with multibyte-
characters now), it does fix #6263 and #7700.

Reset mbstate to initial in wcrtomb() with 0 wchar.

Add multibyte-support to ctype-locale backend.

* add actual converter methods MultibyteToWchar() and WcharToMultibyte()
to locale backend and implement them in the ctype subpart
* add management code for maintaining converters referenced by mbstate_t

Use TLS and converter manager in locale backend.

* Merged weak-symbols branch.
* Fixed trivial merge conflict in src/system/libroot/posix/locale/nl_langinfo.cpp
* Fixed gcc 2 compilation of src/system/glue/init_term_dyn.c.

* no longer keep a separate time-backend, since the implementation needs to
access (data of) the locale backend anyway
* moved more stuff from localtime_fading_out.c to localtime.cpp
* added respective tests to locale_test
