21687726d0 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.

cadbec75d8 Fix shifting tricks in deblocking for big endian
The code interprets an array of 4 uint8_t values as one uint32_t
and does shifts on the value. The same optimization can be
kept in big endian as well, but the shift has to be done in the
other direction.

This code could be made truly independent of endianness, but
that could cause some minimal performance degradaion, at least
in theory.

This makes "make test" pass on big endian, assuming that
WORDS_BIGENDIAN is defined while building.

47ec78843a Don't read an uint8_t array as an uint32_t
This makes the code work properly on big endian.

The MC case is similar to how it's done in the encoder.

Neither of these should have any significant performance
impact.

66c39a4fd4 Remove the array_stack_align.h header from the encoder lib
All of these macros are already available in the common
macros.h header. Unify all the macros to be named ENFORCE_*
instead of mixed FORCE/ENFORCE.

7791a6d28d Use WelsSnprintf instead of a combination of strlen and STRNCAT
This simplifies the code and makes the buffer size checks
more consistent. Additionally, the previous version wrote
the extra space character without checking if it actually fit
into the buffer.

0318922654 Check the right pointer for being non-null in WelsLogDefault
In case the log level was invalid, GetLogTag returns null.
Checking pCtx doesn't make sense since nothing within the
if block uses pCtx.

92fa4eb400 Use strlen instead of WelsStrnlen/STRNLEN for known null terminated strings
strlen is not dangerous if the string is known to be null
terminated (and MSVC does not warn about its use either).

For the cases in the decoder welsCodecTrace.cpp, the string
passed to all WriteString instances is produced by WelsVsnprintf
which always null terminates the buffer nowadays.

Additionally, as the string was passed to OutputDebugStringA
without any length specifier before, it was already assumed to
be null terminated.

The file name parameter passed to DumpDependencyRec and
DumpRecFrame in encoder.cpp is always null terminated,
which was already assumed as it is passed to WelsFopen as is.

As for the encoder utils.cpp, the strings returned by GetLogPath
are string constants that are null terminated.

082a986990 Use strlen() instead of WelsStrnlen/STRNLEN for string constants
A string constant is guaranteed to be null terminated, and thus
doesn't need to use a version of strlen with a fixed buffer size
limit.

3559f425b4 Consistently use the compat wrappers for file IO
As long as WelsFileHandle* is equal to FILE* this doesn't matter,
but for consistency use the WelsF* functions for all handles
opened by WelsFopen, and use WelsFileHandle* as type for it
instead of FILE*.

11bdd8adad Move the measure_time.h header to the common library
Both encoder and decoder versions were functionally equivalent,
but I picked the decoder version (but added the static inline
keywords to it) since the encoder one was quite messy with a lot
of commented out code.

30bcfea6b8 Simplify ifdefs in measure_time.h
Instead of using "defined(MSC_VER) || defined(__MINGW32__)" to
indicate the windows platform, just check for the _WIN32 define
instead.

Also remove an unused codepath - the removed codepath would
only be used under the condition
"(defined(MSC_VER) || defined(__MINGW32__)) && !defined(_WIN32)",
and I'm not aware of any environment with MSVC or MinGW that
doesn't define _WIN32, thus this codepath never was used.

98bad4f2b3 Don't manually null terminate after calling SNPRINTF
The following pattern is unsafe on all platforms:
 n = SNPRINTF(buf, ...);
 buf[n] = '\0';

On windows, the _snprintf variants return a negative number
if the buffer was too small, thus buf[n] would be outside
of (before the start of) the buffer.

On other platforms, the C99 snprintf function returns the
total number of characters which would have been written if
the buffer had been large enough, which can be larger than
the buffer size itself, and thus buf[n] would be beyond the
end of the buffer.

The C99 snprintf function always null terminate the buffer.
These invocations of SNPRINTF are within !WIN32, so we can
be sure that the SNPRINTF call itself already null terminated
the buffer.

89f2c8bf7c Remove a duplicate median function
The decoder used WelsMedian while the encoder used WELS_MEDIAN.
The former has two different implementations, WELS_MEDIAN was
identical to the disabled version of WelsMedian.

Settle on using the same implementation for both decoder and
encoder - whichever version of the implementations is faster
should be used for both.
