If one of the perlasm xlate drivers crashes, OpenSSL's build will
currently swallow the error and silently truncate the output to however
far the driver got. This will hopefully fail to build, but better to
check such things.
Handle this by checking for errors when closing STDOUT (which is a pipe
to the xlate driver).
This is the OpenSSL 1.1.1 version of
https://github.com/openssl/openssl/pull/10883 and
https://github.com/openssl/openssl/pull/10930.

Apart from public and internal header files, there is a third type called
local header files, which are located next to source files in the source
directory. Currently, they have different suffixes like
'*_lcl.h', '*_local.h', or '*_int.h'
This commit changes the different suffixes to '*_local.h' uniformly.

Return error if the output tag buffer size doesn't match
the tag size exactly. This prevents the caller from
using that portion of the tag buffer that remains
uninitialized after an otherwise succesfull call to
CRYPTO_ccm128_tag.
Bug found by OSS-Fuzz.
Fix suggested by Kurt Roeckx.

The add/double shortcut in ecp_nistz256-x86_64.pl left one instruction
point that did not unwind, and the "slow" path in AES_cbc_encrypt was
not annotated correctly. For the latter, add
.cfi_{remember,restore}_state support to perlasm.
Next, fill in a bunch of functions that are missing no-op .cfi_startproc
and .cfi_endproc blocks. libunwind cannot unwind those stack frames
otherwise.
Finally, work around a bug in libunwind by not encoding rflags. (rflags
isn't a callee-saved register, so there's not much need to annotate it
anyway.)
These were found as part of ABI testing work in BoringSSL.

As it turns out originally published results were skewed by "turbo"
mode. VM apparently remains oblivious to dynamic frequency scaling,
and reports that processor operates at "base" frequency at all times.
While actual frequency gets increased under load.

On contemporary platforms assembly GHASH processes multiple blocks
faster than one by one. For TLS payloads shorter than 16 bytes, e.g.
alerts, it's possible to reduce hashing operation to single call.
And for block lengths not divisible by 16 - fold two final calls to
one. Improvement is most noticeable with "reptoline", because call to
assembly GHASH is indirect.

In `aes_wrap_cipher()`, the minimal out buff length is `(inlen - 8)`.
Since it calls `CRYPTO_128_unwrap_pad()` underneath, it makes sense to
reduce the minimal out length in `CRYPTO_128_unwrap_pad()` to align to
its caller.

The make variables LIB_CFLAGS, DSO_CFLAGS and so on were used in
addition to CFLAGS and so on. This works without problem on Unix and
Windows, where options with different purposes (such as -D and -I) can
appear anywhere on the command line and get accumulated as they come.
This is not necessarely so on VMS. For example, macros must all be
collected and given through one /DEFINE, and the same goes for
inclusion directories (/INCLUDE).
So, to harmonize all platforms, we repurpose make variables starting
with LIB_, DSO_ and BIN_ to be all encompassing variables that
collects the corresponding values from CFLAGS, CPPFLAGS, DEFINES,
INCLUDES and so on together with possible config target values
specific for libraries DSOs and programs, and use them instead of the
general ones everywhere.
This will, for example, allow VMS to use the exact same generators for
generated files that go through cpp as all other platforms, something
that has been impossible to do safely before now.

C preprocessor flags get separated from C flags, which has the
advantage that we don't get loads of macro definitions and inclusion
directory specs when linking shared libraries, DSOs and programs.
This is a step to add support for "make variables" when configuring.

MSA level is installed. Therefore, it is sufficient to check the bits returned
by the QUERY functions. The MSA level does not have to be checked at every
function call.

required KM or KMC function codes are not available. Formally, the availability
of a KMC function code does not imply the availability of the corresponding KM

OPENSSL_ia32cap.pod discusses possibility to disable operations on
XMM register bank. This formally means that this flag has to be checked
in combination with other flags. But it customarily isn't. But instead
of chasing all the cases we can flip more bits together with FXSR one.

"Optimize" is in quotes because it's rather a "salvage operation"
for now. Idea is to identify processor capability flags that
drive Knights Landing to suboptimial code paths and mask them.
Two flags were identified, XSAVE and ADCX/ADOX. Former affects
choice of AES-NI code path specific for Silvermont (Knights Landing
is of Silvermont "ancestry"). And 64-bit ADCX/ADOX instructions are
effectively mishandled at decode time. In both cases we are looking
at ~2x improvement.
AVX-512 results cover even Skylake-X :-)

Original text:
Clarify use of |$end0| in stitched x86-64 AES-GCM code.
There was some uncertainty about what the code is doing with |$end0|
and whether it was necessary for |$len| to be a multiple of 16 or 96.
Hopefully these added comments make it clear that the code is correct
except for the caveat regarding low memory addresses.

The assembler already knows the actual path to the generated file and,
in other perlasm architectures, is left to manage debug symbols itself.
Notably, in OpenSSL 1.1.x's new build system, which allows a separate
build directory, converting .pl to .s as the scripts currently do result
in the wrong paths.
This also avoids inconsistencies from some of the files using $0 and
some passing in the filename.

Prevent undefined behavior in CRYPTO_cbc128_encrypt: calling this function
