Avoid requiring byteswapping functions

Instead of byteswapping a 32 bit word and writing it out as a
whole (which could even possibly lead to crashes due to
incorrect alignment on some platforms), write it out explicitly
in the intended byte order.

This avoids having to set a define indicating the endianness.
Make the deblocking handling endian independent

This avoids having to set a define indicating the endianness.

This doesn't incur any significant measurable slowdown.
Consistently use inline instead of __inline

This seemed to have been missed in 109fecc.
Remove typedefs for float_t and double_t

The actual float and double data types are defined in C89 and are
usable as such without any extra typedefs.

Removing the extra typedefs simplifies the compatibility typedef
headers, simplifies portability and makes the code base easier
to work with for people new to the library.
Remove the real32_t typedef

The float type is defined in standards and is portably available
on all supported compilers and platforms.
Include stdbool.h in the public interface headers in C mode

This avoids requiring the callers to explicitly include it before
including codec_api.h

Remove redundant /./ parts from pathnames in makefiles

This is mostly a cosmetic improvement for the quiet make output.

Take the missed WelsDecoderI4x4LumaPredH_sse2 function into use

Previously this function was never used.
Remove an MSVC resource editor state file

This file contains the local UI state of the resource editor,
and should not be committed to version control.

A similar file was removed earlier in c61b040, but this one
was missed.
