Instead of exposing the arm64-optimized SHA-1 code via arm64-specific crypto_shash algorithms, instead just implement the sha1_blocks() library function. This is much simpler, it makes the SHA-1 library functions be arm64-optimized, and it fixes the longstanding issue where the arm64-optimized SHA-1 code was disabled by default. SHA-1 still remains available through crypto_shash, but individual architectures no longer need to handle it. Remove support for SHA-1 finalization from assembly code, since the library does not yet support architecture-specific overrides of the finalization. (Support for that has been omitted for now, for simplicity and because usually it isn't performance-critical.) To match sha1_blocks(), change the type of the nblocks parameter and the return value of __sha1_ce_transform() from int to size_t. Update the assembly code accordingly.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
