* bcache.h: Update copyright.

(struct bstring, struct bcache): Move definition to "bcache.c".
Replaced by opaque declaration.
(bcache_xfree): Replace free_bcache.
(bcache_xmalloc, bcache_memory_used): Declare.

(struct bstring, struct bcache): Moved to here from "bcache.h".
Update comments.
(bcache_xmalloc, bcache_memory_used): New functions.
(bcache_xfree): Replace function free_bcache.

* Makefile.in (objfiles.o): Add $(bcache_h).
(objfiles_h): Remove $(bcache_h).
(symfile.o): Add $(bcache_h).

* symmisc.c: Update copyright.
(print_symbol_bcache_statistics): Pass psymbol_cache by value.
(print_objfile_statistics): Use bcache_memory_used.

* symfile.c: Include "bcache.h".
(reread_symbols): Use bcache_xfree.
(reread_symbols): Use bcache_xmalloc and bcache_xfree.
(add_psymbol_to_list): Pass psymbol_cache by value.
(add_psymbol_with_dem_name_to_list): Ditto.

* objfiles.h: Update copyright.
(struct bcache): Declare opaque.  Do not include "bcache.h".
(struct objfile): Change psymbol_cache and macro_cache to ``struct
bcache'' pointers.
* dwarf2read.c (macro_start_file): Pass macro_cache by value.

* objfiles.c: Include "bcache.h".  Update copyright.
