Without this, when targeting x86, the compiler may not enable sse2
by default without -msse2 switch and therefore leaves WEBP_USE_SSE2
undefined and the SSE2 procedure won't be built.

This enables the executables and the correct flags, it's a full desktop
platform. This is different from the old Windows mobile ARM target.

There's no need for this in libsharpyuv currently. This avoids an ABI
bump and library size increase.

Basic version for 8 bit only and C only (no simd).
Hidden behind a compile flag because the precompiled table is
fairly large (114kiB) and more than triples the size of the library.

Initially added to workaround gcc implementation issues that clang
does not have. (gcc hardcodes rbx as the PIC register, clang uses a
virtual register)

When WebPSafeMalloc fails on VP8LHuffmanTablesAllocate,
next is not initialized to NULL.
VP8LHuffmanTablesDeallocate uses next to know the following nodes.
A patch fixes this issue.

The first condition is only necessary if we have not read enough
(enough being defined by src_last, not src_end which is the end
of the image).
The second condition now fits the comment below: "if not
incremental, and we are past the end of buffer".

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.

According to https://gcc.gnu.org/onlinedocs/gcc/extensions-to-the-c-language-family/how-to-use-inline-assembly-language-in-c-code.html
For the C language, the asm keyword is a GNU extension. When
writing C code that can be compiled with -ansi and the -std options
that select C dialects without GNU extensions, use __asm__ instead
of asm (see Alternate Keywords). For the C++ language, asm is a
standard keyword, but __asm__ can be used for code compiled with
-fno-asm.
