* config/tc-hppa.c (subspace_dictionary_chain): Add new ssd_defined 

field.  Define SUBSPACE_DEFINED accessor macro.
	(pa_subspace): Allow user to override subspace attributes for
	built-in subspaces.  Set ssd_defined at the end of fcn -- that
	way the attributes can only be changed once.  Pass newly allocated
	name to is_defined_subspace, not a pointer to the input line.
	Fix typo in space/subspace rework.
	(is_defined_subspace): Delete unused 2nd arg.  All callers changed.

	* config/tc-hppa.c (pa_import): If currently in the text segment
	and a symbol is imported without type information, set BSF_FUNCTION
	for the symbol.

the section's size was rounded up.
