arm64: Use the fault handler when one is provided
In align_abort() and tag_check_abort(), if we got a fault while in kernel,
do not panic if a fault handler has been provided. We may get such a fault
when trying to read or write userland data, it can at least happen with
_umtx_op() if an unaligned pointer is provided. Instead, just let the
fault handler deal with it.

exterror: advertise error strings via kern.features.exterr_strings
Allow userland, in particular test cases for EXTERROR conversions,
to detect at run time whether extended errors include the
descriptive message strings, which depends on the EXTERR_STRINGS
kernel option and cannot be probed in any other way.

install: drop obsolete file size limit for -C
Removes the file size limit for -C comparisons. The limit was
meant to prevent oversized mmap allocations, which is no longer

install: Bump compare size limit (128MB) to support large binaries
Preserve metadata and prevent redundant disk writes during builds with
the install's -C (compare) flag.
The previous historical comparison limit of 16MB is insufficient for
modern toolchains, frequently choked or bypassed by a large base
components like LLVM/Clang, kernels, Rust apps, and large runtime
libraries.
By leaving matching files alone, install keeps their modification timestamps
intact. make(1) safely ignores those files on subsequent runs.
Base examples: 15.0 amd64 GENERIC kernel - 28MB, clang - 105MB, lldb - 97MB, etc.
