The FSF's Licensing and Compliance Lab noted a discrepancy in the
licensing of several files in the glibc package.
When timespect_get.c was impelemented the license did not include
the standard ", or (at your option) any later version." text.
Change the license in timespec_get.c and all copied files to match
the expected license.
This change was previously approved in principle by the FSF in
RT ticket #1316403. And a similar instance was fixed in
commit 46703efa02.
Delay setting file->decided until the data has been successfully loaded
by _nl_load_locale(). If the function fails to load the data then we
must return and error and leave decided untouched to allow the caller to
attempt to load the data again at a later time. We should not set
decided to 1 early in the function since doing so may prevent attempting
to load it again. We want to try loading it again because that allows an
open to fail and set errno correctly.
On the other side of this problem is that if we are called again with
the same inputs we will fetch the cached version of the object and carry
out no open syscalls and that fails to set errno so we must set errno to
ENOENT in that case. There is a second code path that has to be handled
where the name of the locale matches but the codeset doesn't match.
These changes ensure that errno is correctly set on failure in all the
return paths in _nl_find_locale().
Adds tst-locale-loadlocale to cover the bug.

With modern ssh clients and daemons it is required to use AcceptEnv and
SendEnv configuration options to correctly support testing the DSO sort
ordering tests. This requirement is present because
scripts/dso-ordering-test.py injects GLIBC_TUNABLES to the left of the
${test_wrapper_env} and so it must both be sent by the ssh client and
accepted by the ssh daemon. This requirement is removed in this change
and the injected GLIBC_TUNABLES is placed after ${run_program_env} and
so still correctly provides the override that the test requires.
This is similar to existing tests like elf/tst-pathopt.sh,
elf/tst-rtld-load-self.sh, and locale/tst-locale-locpath.sh.
Tested that it fixes two failures when cross-testing on aarch64 with
scripts/cross-test-ssh.sh and an ssh client and daemon that do not pass
GLIBC_TUNABLES. Without this fix such a configuration will report the
following failures (since the GLIBC_TUNABLES not preserved):

These failures were caught while building glibc master for Fedora
Rawhide which is built with '-mtune=generic -msse2 -mfpmath=sse'
using gcc 11.3 (gcc-11.3.1-2.fc35) on a Cascadelake Intel Xeon
processor.
In commit 063f9ba220 the NEWS section
was accidentally added to the glibc 2.34 NEWS section. The NEWS entry
should have been added to glibc 2.35 which contained the committed
fix. This moves the NEWS entry to correct section.

ISO C17, POSIX Issue 7, and ISO 30112 all allow the char*
types to be empty strings i.e. "", integer or char values to
be -1 or CHAR_MAX respectively, with the exception of
decimal_point which must be non-empty in ISO C. Note that
the defaults for mon_grouping vary, but are functionaly
equivalent e.g. "\177" (no further grouping reuqired) vs.
"" (no grouping defined for all groups).
We include a broad comment talking about harmonizing ISO C,
POSIX, ISO 30112, and the default C/POSIX locale for glibc.
We reorder all setting based on locale/categories.def order.
We soften all missing definitions from errors to warnings when
defaults exist.
Given that ISO C, POSIX and ISO 30112 allow the empty string
we change LC_MONETARY handling of mon_decimal_point to allow
the empty string. If mon_decimal_point is not defined at all
then we pick the existing legacy glibc default value of
<U002E> i.e. ".".
We also set the default for mon_thousands_sep_wc at the
same time as mon_thousands_sep, but this is not a change in
behaviour, it is always either a matching value or L'\0',
but if in the future we change the default to a non-empty
string we would need to update both at the same time.

so with this commit we review and fix all the issues that
cause the builtin C locale to be different from C.UTF-8,
which includes:
* mon_decimal_point should be empty e.g. ""
- Depends on mon_decimal_point_wc fix.
* negative_sign should be empty e.g. ""
* week should be aligned with the builtin C/POSIX locale
* d_fmt corrected with escaped slashes e.g. "%m//%d//%y"
* yesstr and nostr should be empty e.g. ""
* country_ab2 and country_ab3 should be empty e.g. ""
We bump LC_IDENTIFICATION version and adjust the date to
indicate the change in the locale.

The handling of mon_decimal_point is incorrect when it comes to
handling the empty "" value. The existing parser in monetary_read()
will correctly handle setting the non-wide-character value and the
wide-character value e.g. STR_ELEM_WC(mon_decimal_point) if they are
set in the locale definition. However, in monetary_finish() we have
conflicting TEST_ELEM() which sets a default value (if the locale
definition doesn't include one), and subsequent code which looks for
mon_decimal_point to be NULL to issue a specific error message and set
the defaults. The latter is unused because TEST_ELEM() always sets a
default. The simplest solution is to remove the TEST_ELEM() check,
and allow the existing check to look to see if mon_decimal_point is
NULL and set an appropriate default. The final fix is to move the
setting of mon_decimal_point_wc so it occurs only when
mon_decimal_point is being set to a default, keeping both values
consistent. There is no way to tell the difference between
mon_decimal_point_wc having been set to the empty string and not
having been defined at all, for that distinction we must use
mon_decimal_point being NULL or "", and so we must logically set
the default together with mon_decimal_point.
Lastly, there are more fixes similar to this that could be made to
ld-monetary.c, but we avoid that in order to fix just the code
required for mon_decimal_point, which impacts the ability for C.UTF-8
to set mon_decimal_point to "", since without this fix we end up with
an inconsistent setting of mon_decimal_point set to "", but
mon_decimal_point_wc set to "." which is incorrect.

We add a new C.UTF-8 locale. This locale is not builtin to glibc, but
is provided as a distinct locale. The locale provides full support for
UTF-8 and this includes full code point sorting via STRCMP-based
collation (strcmp or wcscmp).
The collation uses a new keyword 'codepoint_collation' which drops all
collation rules and generates an empty zero rules collation to enable
STRCMP usage in collation. This ensures that we get full code point
sorting for C.UTF-8 with a minimal 1406 bytes of overhead (LC_COLLATE
structure information and ASCII collating tables).
The new locale is added to SUPPORTED. Minimal test data for specific
code points (minus those not supported by collate-test) is provided in
C.UTF-8.in, and this verifies code point sorting is working reasonably
across the range. The locale was tested manually with the full set of
code points without failure.
The locale is harmonized with locales already shipping in various
downstream distributions. A new tst-iconv9 test is added which verifies
the C.UTF-8 locale is generally usable.
Testing for fnmatch, regexec, and recomp is provided by extending
bug-regex1, bugregex19, bug-regex4, bug-regex6, transbug, tst-fnmatch,
tst-regcomp-truncated, and tst-regex to use C.UTF-8.

Support a new directive 'codepoint_collation' in the LC_COLLATE
section of a locale source file. This new directive causes all
collation rules to be dropped and instead STRCMP (strcmp or
wcscmp) is used for collation of the input character set. This
is required to allow for a C.UTF-8 that contains zero collation
rules (minimal size) and sorts using code point sorting.
To date the only implementation of a locale with zero collation
rules is the C/POSIX locale. The C/POSIX locale provides
identity tables for _NL_COLLATE_COLLSEQMB and
_NL_COLLATE_COLLSEQWC that map to ASCII even though it has zero
rules. This has lead to existing fnmatch, regexec, and regcomp
implementations that require these tables. It is not correct
to use these tables when nrules == 0, but the conservative fix
is to provide these tables when nrules == 0. This assures that
existing static applications using a new C.UTF-8 locale with
'codepoint_collation' at least have functional range expressions
with ASCII e.g. [0-9] or [a-z]. Such static applications would
not have the fixes to fnmatch, regexec and regcomp that avoid
the use of the tables when nrules == 0. Future fixes to fnmatch,
regexec, and regcomp would allow range expressions to use the
full set of code points for such ranges.
