Berthold Stoeger f93acdace7 cleanup: make alloc_taxonomy local to taxonomy.c
The alloc_taxonomy()/free_taxonomy() interface was exceedingly strange.
The former gave a "struct taxonomy", the latter took a "struct taxonomy_data".
To make things worse, is appears as if the names "taxonomy" and "taxonoma_data"
are reversed: the latter contains the former.

In any case, the alloc_taxonomy() call is not needed anymore from outside
taxonomy.c, as these memory-management details are now hidden in accessor
functions. Therefore, make the function local to taxonomy.c. Moreover,
rename it to "alloc_taxonomy_table()" and let it take a "taxonomy_data"
structure for symmetry with "free_taxonomy()".
