Tom Tromey 0e6f30610f Remove some unused buildsym functions 
Now that the DWARF reader uses the builder-based API, we can remove a
few "legacy" functions that were only ever called by it.

Tom Tromey 80e649fcac Parameterize cp_scan_for_anonymous_namespaces 
This changes cp_scan_for_anonymous_namespaces to use the
buildsym_compunit API, rather than the function-based API.

	* cp-support.h (cp_scan_for_anonymous_namespaces): Update.
	* cp-namespace.c: Include buildsym.h.
	(cp_scan_for_anonymous_namespaces): Add "compunit" parameter.

Tom Tromey 0baae8dbd3 Introduce buildsym-legacy.h 
This introduces a new header, buildsym-legacy.h, and changes all the
symbol readers to use it.  The idea is to put the function-based
interface, that relies on the buildsym_compunit global, into a
separate header.  Then when a symbol reader is updated to use the new
interface, it can simply not include buildsym-legacy.h, so it's easy
to be sure that the new API is used everywhere.
