    • This patch implements the unification of the *bitmap interfaces as discussed. · f61e445a 
      Essentially, we rename ebitmap and sbitmap functions to use the same names
as the bitmap functions.  This rename works because we can now overload
on the bitmap type.  Some macros now become inline functions to enable
that overloading.

The sbitmap non-bool returning bitwise operations have been merged with
the bool versions.  Sometimes this merge involved modifying the non-bool
version to compute the bool value, and sometimes modifying bool version to
add additional work from the non-bool version.  The redundant routines have
been removed.

The allocation functions have not been renamed, because we often do not
have an argument on which to overload.  The cardinality functions have not
been renamed, because they have different parameters, and are thus not
interchangable.  The iteration functions have not been renamed, because
they are functionally different.

Tested on x86_64, contrib/config-list.mk testing passed.

    • remove useless if-before-free tests · 04695783 
      Change "if (E) free (E);" to "free (E);" everywhere except in the
libgo/, intl/, zlib/ and classpath/ directories.
Also transform equivalent variants like
"if (E != NULL) free (E);" and allow an extra cast on the
argument to free.  Otherwise, the tested and freed "E"
expressions must be identical, modulo white space.
