Previously the test programmes happened to link because _getpid
returns an int, which is the default prototype. Instead, include
the appropriate header to supply a real declaration, fixing the
associated warning.

I moved the getpid->_getpid define to the site of the header
inclusion to make clear what's going on, rather than have it
floating in win32/config.h.

Updates the project files to include the new encoder source files.
Use OPUS_RESTRICT and include config.h to set the proper defines
for build under MSVC.

The Microsoft compiler warns about precision reduction from
default double literals to the floats we generally use outside
the fixed-point build. Avoid these by qualifying the literals
as floats.

Thanks to derf for review.

Saves some memory access and gives a tiny speedup

This fixes a SWB hybrid issue where band 18 isn't folded and cannot even
be folded because it's wider than band 17. This was causing noise to
be injected instead.

Adds a gain cross-fade to avoid discontinuities and moves it
to a place where it won't affect SILK

I stumbled upon the typo in README.draft, so took the opportunity to
grep for common misspellings using List_of_common_misspellings.txt for
hunspell.

These were only needed with RESYNTH defined

This fixes a problem where we could end up starving the redundancy
frame, especially for CBR. The solution is to make sure that some
bits are left available -- assuming we use the same rate for redundancy
as for the rest of the frame.

Doing it this way means it's only the weird corner case that actually
pays for being weird, and we don't litter the build dir with an extra
link that normal builds really don't need at all.

It also avoids the problem of platforms where LN_S isn't well defined.

This could be confusing/misleading.

Prefilling didn't use the right offset because of the extra_delay
changes introduced in the analysis branch.

Mostly this is for people building other things using an uninstalled
opus tree so that the opus-uninstalled.pc will return a working -I
with --cflags when PKG_CONFIG_PATH is set to point to the build dir.

The version of AC_OUTPUT that takes parameters has long been
deprecated now, and replaced by AC_CONFIG_* macros, so pass them
with AC_CONFIG_FILES, since we're now using AC_CONFIG_COMMANDS
to do the above.

The floating-point build calls a number of math library
functions, and linking with libm is technically necessary.
It wasn't obvious because most systems support shlib
dependencies and pulled it in that way, or supply the
referenced functions with intrinsics. Discovered the issue
trying to build libopusfile against the uninstalled static
libopus, which unlike opus-tools, doesn't itself need libm.

The -lm argument is only added to Libs for the floating-
point (default) build. It's not necessary for the fixed-
point build.

Also mark which build was used in the .pc file description.
