First, BuildHuffmanTable is called to check if the data is valid.
If it is and the table is not big enough, more memory is allocated.
This will make sure that valid (but unoptimized because of unbalanced
codes) streams are still decodable.

Also fix the variables: we need to check for PTHREAD_PRIO_INHERIT
and PTHREAD_CREATE_JOINABLE (not PTHREAD_CREATE_UNDETACHED) and
internally use HAVE_PTHREAD_PRIO_INHERIT and PTHREAD_CREATE_JOINABLE
(and not HAVE_PTHREAD_CREATE_JOINABLE).
cmake/config.h.in actually had the right variables.

memory-alloc limit (8M).
Raise this limit reasonably if it looks like the input bitstream

It's explicitly safe (and recommended!) to plug external data into
the pic->y/u/v/argb fields. They are guaranteed to be preserved
by the encoding process if no conversion is needed.

this is similar to iosbuild.sh, but will create .xcframework variants to
support Catalyst targets. currently it includes libs for:
ios-arm64_armv7_armv7s
ios-arm64_x86_64-maccatalyst
ios-i386_x86_64-simulator
macos-arm64_x86_64
this script requires Xcode 12+ to target arm64 for mac/catalyst, Xcode
11 builds will create x86_64 libraries only. iosbuild.sh remains for
compatibility purposes

Since
a376e7b9 Fix compilation on windows and clang-cl+ninja.
the highest level assembly flag (/arch:AVX / -msse4.1) would be applied
to all assembly files. This could result in higher level instructions
being used which would defeat the runtime cpu detection check and could
result in a crash.
With this change -m style flags are used with clang-cl as it supports
them and allows the correct level to be set. With at least Visual
Studio 12 (2013)+ /arch is not necessary to build SSE2 or SSE4 code
unless a lesser /arch is forced so these flags are avoided. This matches
the nmake build.
For emscripten only sse2 and sse4.1 are tested (NEON will succeed in
being enabled, but fail to build). This is consistent with
the current behavior added in:

Add a stub file to object only library targets.

Some native build systems (such as Xcode) may not like targets that have
only object files, so consider adding at least one real source file to
any target that references $<TARGET_OBJECTS:objlib>.

- Add `-msimd128` to flags to actually enable WebAssembly SIMD
when performing SIMD detection. It's currently required in
addition to `-msse*` / `-mfpu=neon` flags which only perform
translation of corresponding intrinsics to Wasm SIMD ones.
See a discussion at emscripten-core/emscripten#12714 for
automating this and making easier in the future.
- Remove compilation branch that prevented definitions of
`WEBP_USE_SSE` and `WEBP_USE_NEON` on Emscripten even when
SIMD support was detected at compile-time.
- Add an implementation of `VP8GetCPUInfo` for Emscripten which
uses static `WEBP_USE_*` flags to determine if a corresponding
SIMD instruction is supported. This is because Wasm doesn't
have proper feature detection (yet) and requires making separate
build for SIMD version anyway.

The offset *can* be negative, but the sanitizer reports strange
address behaviour when row_offset is unsigned size_t.
For safety, use int64_t instead (probably overkill. int32_t is probably ok).
