Add HMAC support to the SHA-1 library, again following what was done for
SHA-2. Besides providing the basis for a more streamlined "hmac(sha1)"
shash, this will also be useful for multiple in-kernel users such as
net/sctp/auth.c, net/ipv6/seg6_hmac.c, and
security/keys/trusted-keys/trusted_tpm1.c. Those are currently using
crypto_shash, but using the library functions would be much simpler.

Add a library interface for SHA-1, following the SHA-2 one. As was the
case with SHA-2, this will be useful for various in-kernel users. The
crypto_shash interface will be reimplemented on top of it as well.

Rename the existing sha1_init() to sha1_init_raw(), since it conflicts
with the upcoming library function. This will later be removed, but
this keeps the kernel building for the introduction of the library.

Fix build warnings with W=1 that started appearing after
commit a934a57a42f6 ("scripts/misc-check: check missing #include
<linux/export.h> when W=1").
While at it, also sort the include lists alphabetically. (Keep
asm/irqflags.h last, as otherwise it doesn't build on alpha.)
This handles all of lib/crypto/, but not arch/*/lib/crypto/. The
exports in arch/*/lib/crypto/ will go away when the code is properly
integrated into lib/crypto/ as planned.

asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.

With ARCH=arm, make allmodconfig && make W=1 C=1 reports:
WARNING: modpost: missing MODULE_DESCRIPTION() in lib/crypto/libsha256.o
Add the missing invocation of the MODULE_DESCRIPTION() macro to all
files which have a MODULE_LICENSE().
This includes sha1.c and utils.c which, although they did not produce
a warning with the arm allmodconfig configuration, may cause this
warning with other configurations.

libsha1 can be a module, so it needs a MODULE_LICENSE.

SHA-1 is a crypto algorithm (or at least was intended to be -- it's not
considered secure anymore), so move it out of the top-level library
directory and into lib/crypto/.
