This way it won't interfere with WMV9 initialisation inside MSS2 decoder and
avplay will play it fine.

This is necessary to avoid spuriously enabling _external or _inline
variants of arch extensions when they should be disabled.

PATH_MAX is not necessarily available on all systems, e.g. it's
normally not available on MSVC, and is not guaranteed to defined
on a POSIX system either.

This takes care of null-terminating the buffer if it is too small,
which wasn't handled properly before.

Also change the snprintf size to use the full buffer, since
snprintf always null-terminates the buffer.

Some optimized template functions reference optimized symbols, so they
must be explicitly disabled when those symbols are unavailable.

Also, align the mangled RGB planes, which is required for the
SIMD versions of dsputils' median predict.

func2_arg is the same as func_arg, except it has one additional
parameter. Change all func_arg callbacks to take that parameter (and
ignore it).

This enables replacing the -l and -L flags used to specify the
just-built libraries when linking the tools and shared libs with
non-standard syntaxes.  System library flags are already handled
by the filtering mechanism in configure.

This adds new HOSTLD and related settings for host linker allowing

Some tools use different command line syntax for specifying output
when compiling and linking.  To accomodate these, separate variables
must be used.  No currently supported compilers/linkers are affected
by the change.

The optimized dct_quantize template functions reference optimized
fdct symbols, so these functions must only be enabled if the relevant
optimizations have been enabled by configure.

This avoids trouble if HAVE_ variables are used elsewhere in the file.

This introduces support for width%4==2 in addition to width%4==0. For
odd widths, some more checks are needed, since the current code always
handles two luma items in a row, thus there is a possibility of an
overread by one.
