 - Do not define macros, functions, or variables with file scope using
   names beginning with an underscore (these names are reserved for the
   implementation; see C89 section 7.1.3 or any later version) or that
   shadow other global declarations
 - Avoid declarations after statements (speex_assert) for C89 compat
 - Silence unused parameter warning in resampler_basic_zero
 - No need for the stack_alloc.h macros within #ifdef VAR_ARRAYS; use
   the standard C syntax
 - When OUTSIDE_SPEEX, define EXPORT if not already defined
 - Update URL to https

Make sure we don't overflow when calculating the phase for the new
sample rate.

Use Euclids algorithm to calculate the greatest common divisor to
simplify the resample ratio fraction instead of the slow iterative
method.

This isn't needed (and isn't doing anything here anyway).

Not everyone who includes speexdsp_config_types.h will have a test
which defines those, and if we've chosen to use the stdint types at
configure time then we know exactly which header(s) are available, so
just choose the best one then and generate the header to use it.

This patch, including the above text, is copied from a commit in the
speex repository[1]. The original commit for speex was made by Ron
<ron@debian.org>.
