If a memory-mapped file is truncated before we get to the end, the
atomizer may catch SIGBUS. Detect that, reduce the input length to
what we were actually able to read, and set a flag so the caller can
take further action (e.g. warn the user and / or start over).

This /etc/resolv.conf:
# x
# nameserver 8.8.8.8
Still configured 8.8.8.8 as nameserver, because the comment detection in `ldns_resolver_new_frm_fp_l()` didn't anticipate empty lines before the comment.
This fix removed all comment handling from `ldns_resolver_new_frm_fp_l()`. Instead a new function is introduced `ldns_fget_token_l_resolv_conf()` that skips comments that start with '#' and ';'. The old `ldns_fget_token_l()` (that is used for zonefiles too) still accepts only ';' for comments.
In the last 2nd edition import, I mistakenly grabbed from the 'main'
branch of upstream rather than the bsd-feature branch. This means that
we have a regression in awk from that point forward: all the
BSD-specific bit functions (and a few others) were dropped. This
restores it at the same level.

- libc needs to #undef some of the macros from ssp/* for underlying

- ssp/* wants a __RENAME() macro (snatched more or less from NetBSD)

[OpenMP] Fix child processes to use affinity_none (#91391)
When a child process is forked with OpenMP already initialized, the
child process resets its affinity mask and sets proc-bind-var to false
so that the entire original affinity mask is used. This patch corrects
an issue with the affinity initialization code setting affinity to
compact instead of none for this special case of forked children.
The test trying to catch this only testing explicit setting of
KMP_AFFINITY=none. Add test run for no KMP_AFFINITY setting.
Fixes: #91098
This should fix OpenMP processes sometimes getting stuck on a single CPU

[OpenMP] Fix re-locking hang found in issue 86684 (#88539)
This was initially reported here (including stacktraces):
https://stackoverflow.com/questions/78183545/does-compiling-imagick-with-openmp-enabled-in-freebsd-13-2-cause-sched-yield
If `__kmp_register_library_startup()` detects that another instance of
the library is present, `__kmp_is_address_mapped()` is eventually
called. which uses `kmpc_alloc()` to allocate memory. This function
calls `__kmp_entry_thread()` to access the thread-local memory pool,
which is a bad idea during initialization. This macro internally calls
`__kmp_get_global_thread_id_reg()` which sets the bootstrap lock at the
beginning (before calling `__kmp_register_library_startup()`).
The fix is to use `KMP_INTERNAL_MALLOC()`/`KMP_INTERNAL_FREE()` instead
of `kmpc_malloc()`/`kmpc_free()`. `KMP_INTERNAL_MALLOC` and
`KMP_INTERNAL_FREE` do not use any bootstrap locks. They just translate
to `malloc()`/`free()` and are meant to be used during library
initialization before other library-specific allocators have been
initialized.
Fixes: #86684
This should fix OpenMP processes sometimes getting locked with 100% CPU
usage, endlessly calling sched_yield(2).

[sanitizer_symbolizer] Cast arguments for format strings in markup (#89815)

This is because `uptr` is dependent on the platform, and can be either

[libc++] Re-enable std::pair trivial copy constructor for FreeBSD >= 14
After many years of using the really old std::pair ABI which did not yet
have a trivial copy constructor, FreeBSD 14 and later will finally get
rid of it. Only use the old ABI for FreeBSD 13 and earlier.
Note: on the FreeBSD side, we will bump our libc++.so version for this,
and keep an old compatibility library in a separate package.
Differential Revision: https://reviews.llvm.org/D126462
This ABI change can cause crashes when binaries compiled against older
libc++ versions are run against binaries compiled against this libc++
version.
For example, lang/ldc uses a precompiled bootstrap ldc2 binary that was
compiled against the old libc++, but also links against libLLVM-15.so.
If libLLVM-15.so is compiled against the new libc++ version, the ABI
mismatch results in segfaults or even stack overflows.
Note: we can only re-enable the std::pair trivial copy constructors
again when the official libc++ ABI version is bumped to 2.

As of 4d20cfcf4eb08217ed37c4d4c38dc395d7a66d26, `__bit_reference`
contains a template `__fill_n` with a bool `_FillValue` parameter.
Unfortunately there is a relatively widely used piece of scientific
software called NetCDF, which exposes a (C) macro `_FillValue` in its
public headers.
When building the NetCDF C++ bindings, this quickly leads to compilation
errors when the macro interferes with the template in `__bit_reference`.
Rename the parameter to `_FillVal` to avoid the conflict.

[Clang][AST] Fix a crash on attaching doc comments (#78716)
This crash is basically caused by calling
`ASTContext::getRawCommentForDeclNoCacheImp` with its input arguments
`RepresentativeLocForDecl` and `CommentsInTheFile` refering to different
files. A reduced reproducer is provided in this patch.
After the source locations for instantiations of funtion template are
corrected in the commit 256a0b298c68b89688b80350b034daf2f7785b67, the
variable `CommitsInThisFile` in the function
`ASTContext::attachCommentsToJustParsedDecls` would refer to the source
file rather than the header file for implicit function template
instantiation. Therefore, in the first loop in
`ASTContext::attachCommentsToJustParsedDecls`, `D` should also be
adjusted for relevant scenarios like the second loop.
