Add missing parenthesis

One parenthesis is missing, and it causes a compilation error.  This
patch is to fix it.

	* go32-nat.c (go32_create_inferior): Add missing parenthesis.
expand_symtab_containing_pc: Renamed from find_pc_sect_symtab_via_partial.

This patch just renames one function.
Its only caller is in stack.c where we're printing a backtrace
with non-zero info_verbose and we want to make sure all the needed
symtabs are expanded before printing the backtrace
so that debug symbol reading messages don't pollute the backtrace.

I think the new name of the function makes clearer to the reader
what is going on.

gdb/ChangeLog:

	* symtab.c (expand_symtab_containing_pc): Renamed from
	find_pc_sect_symtab_via_partial.  All callers updated.

Basically the problem is that "symtab" is ambiguous.
Is it the primary symtab (where we canonically think of
blockvectors as being stored) or is it for a specific file
(where each file's line table is stored) ?

gdb_disassembly wants the symtab that contains the line table
but is instead getting the primary symtab.
