mfiutil(8): "show drives" truncates information
Improve mfi_pd_inq_string() by
* Reusing buffer sizes from cam/cam.h according to SCSI specification + NULL byte
* Don't truncate vendor-specific information by escaping into a too small buffer
* Use cam_strvis() from libcam instead of old, outdated local copy
* Recaculate size of inq_string based on the reused buffer sizes and
format statements

Diable a few options unlikely to be all that useful on a NeXT:
- COMPAT_NOMID, COMPAT_SUNOS
- file-system MFS (TMPFS is preferred)
- dse, se (SCSI Ethernet)
- sl (SLIP), ppp / pppoe
Shrinks the kernel by ~167KB.

[Headers][X86] Remove more duplicated typedefs (#153820)
They are defined in mmintrin.h
This fixes a -Werror warning in openzfs, which compiles for C99, and C99
does not allow for typedef redefinitions.

[libc++] Fix iostream size ABI break (#185839)
In #124103 we changed the size of various iostream objects, which turns
out to be ABI breaking when compiling non-PIE code.
This ABI break is safe to fix, since for any programs allocating more
memory for the iostream objects, the remaining bytes are simply unused
now.
Fixes #185724
This fixes the ABI break that causes programs that use the standard
streams to terminate in various interesting ways, usually by throwing an
unexpected std::bad_cast exception.

[libc++] Fix std::make_exception_ptr interaction with ObjC (#135386)
Clang treats throwing/catching ObjC types differently from C++ types,
and omitting the `throw` in `std::make_exception_ptr` breaks ObjC
invariants about how types are thrown/caught.
Fixes #135089

Only use lambdas when in !defined(_LIBCPP_CXX03_LANG), so this will
compile with clang 18 and lower, in C++03 mode and earlier.

`__libcpp_popcount` was previously used as a fallback for `__builtin_popcountg` to ensure compatibility with older compilers (Clang 18 and earlier), as `__builtin_popcountg` became available in Clang 19. Now that support for Clang 18 has been officially dropped in #130142, we can now safely replace all instances of `__libcpp_popcount` with `__builtin_popcountg` and eliminate the fallback logic.
